Summary

Adds two comprehensive skills for integrating Mapbox Model Context Protocol (MCP) servers into development and production workflows.

New Skills

1. mapbox-mcp-devkit-patterns (Development-time)

For: Developers using AI coding assistants (Claude Code, Cursor, Windsurf, etc.)

Covers:

  • Setting up Mapbox MCP DevKit Server in coding environments
  • Style management workflows (conversational creation/updates)
  • Token management (scoped tokens, environment-specific)
  • Validation workflows (GeoJSON, expressions, coordinates)
  • Documentation access through AI
  • Integration patterns for Claude Code, Cursor, Windsurf, Cline
  • Security best practices and testing

Key patterns:

  • Iterative style development with AI
  • Environment-specific token generation
  • Validation-first development
  • Documentation-driven development

2. mapbox-mcp-runtime-patterns (Production-time)

For: Developers building AI applications with geospatial capabilities

Covers:

  • Integrating Mapbox MCP Server into AI frameworks:
    • pydantic-ai (Python)
    • mastra (TypeScript)
    • LangChain (JavaScript/TypeScript)
    • Custom agents
  • Architecture patterns (MCP as service layer, hybrid approaches)
  • Real-world use cases:
    • Real estate apps (Zillow-style) with commute calculations
    • Food delivery apps (DoorDash-style) with delivery zones
    • Travel planning apps (TripAdvisor-style) with itineraries
  • Performance optimization (caching, batching, tool selection)
  • Error handling and rate limiting
  • Security and testing

Key patterns:

  • Framework-specific integration code
  • Domain-specific agent implementations
  • Cost optimization (offline vs API tools)
  • Production error handling

Files Changed

  • skills/mapbox-mcp-devkit-patterns/SKILL.md - Comprehensive DevKit guide (~620 lines)
  • skills/mapbox-mcp-devkit-patterns/AGENTS.md - Quick reference (~230 lines)
  • skills/mapbox-mcp-runtime-patterns/SKILL.md - Comprehensive runtime guide (~880 lines)
  • skills/mapbox-mcp-runtime-patterns/AGENTS.md - Quick reference (~400 lines)
  • skills/README.md - Added both new skills to index
  • cspell.config.json - Added terms: pydantic, Pydantic, Popen, langchain

Why These Skills?

MCP provides a new way to access Mapbox capabilities through AI agents, but developers need guidance on:

  1. How to set up MCP in development (DevKit patterns)
  2. How to integrate MCP in production apps (Runtime patterns)

These skills fill that gap with concrete code examples, architecture patterns, and real-world use cases.

Test Plan

  • All checks passing (spell check, markdown lint, validation)
  • Both skills follow Agent Skills specification
  • Code examples are syntactically correct
  • Framework integrations tested (TypeScript and Python)
  • Real-world use cases included with working code
  • AGENTS.md quick references created

@mattpodwysocki mattpodwysocki requested a review from a team as a code owner February 5, 2026 17:57
mattpodwysocki and others added 10 commits February 5, 2026 13:05
Updates both MCP skills to lead with Mapbox's hosted servers as the recommended approach:

**DevKit patterns:**
- Primary: Hosted server at https://mcp-devkit.mapbox.com/mcp
- OAuth authentication (no token config needed for interactive flows)
- Alternative token auth for specific use cases
- Self-hosted as secondary option for advanced users

**Runtime patterns:**
- Primary: Hosted server at https://mcp.mapbox.com/mcp
- Token-based authentication (standard for programmatic access)
- Note about OAuth being available but primarily for interactive flows
- Self-hosted as secondary option for custom deployments

Benefits of hosted approach:
- Zero installation/setup
- Always up-to-date
- Production-ready infrastructure
- OAuth support for DevKit (secure, no token storage)
- Lower latency (Mapbox infrastructure)

Updated code examples to use hosted URLs with proper authentication patterns.

Added spell check term: getenv

Resolve conflicts in cspell.config.json by keeping all words from both branches.

Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
Added new "Writing Effective Tool Descriptions" section to SKILL.md covering:
- Common confusion points between similar tools (directions vs distance, category vs specific search, etc.)
- Examples of ambiguous vs clear tool descriptions
- Best practices for writing descriptions that help LLMs choose correctly
- System prompt guidance for tool selection

Updated all example tool descriptions to be more specific:
- Clarify when to use get_directions (route along roads with traffic) vs calculate_distance (straight-line)
- Specify category_search is for browsing types vs search_geocode for specific places
- Explain get_isochrone returns reachable area vs get_directions for specific route
- Added system prompt tool selection rules to all examples (LangChain, Mastra, CrewAI)

This addresses the critical issue of ensuring LLMs call the right MCP tools by providing clear, actionable guidance.

Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
Moved key conceptual distinctions to appear before framework integrations:
- "As the crow flies" vs "along roads" (straight-line vs route distance)
- Category search vs specific place search
- Reachable area (isochrone) vs specific route (directions)
- Offline tools vs API tools (cost and performance implications)

This ensures developers understand the fundamental concepts before diving into
framework-specific code examples, reducing confusion about when to use which tools.

Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
Updated SKILL.md code snippets to demonstrate the pattern:
- CrewAI: Added tool selection guidance to agent backstories
- LangChain: Updated tool descriptions to be specific and actionable

This ensures developers see the complete pattern when reading docs:
1. Understand concepts (Understanding Tool Categories section)
2. See it applied in framework examples (agent backstories/descriptions)
3. Get detailed guidance (Writing Effective Tool Descriptions section)

Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
The previous example used an undefined isAIAgentCall() method that:
- Had no implementation
- Wasn't clear how to detect
- Suggested runtime decision when it's actually architecture decision

Replaced with clear examples showing:
- AI agent features use MCP (natural language, tool chaining)
- Direct app features use SDK (map rendering, UI controls)
- Offline features always use MCP/Turf.js (free, instant)

Added decision table to clarify when to use each approach.

I think this is a mismatch - claude code is in a .claude.json file in the ~, claude desktop's config is, I believe, in an application folder.

✅ and ❌ seem a bit confusing as I'm assuming its use or the other?
Should it just be a 3 column table with all the scenarios and a green check under either use devkit or use direct API's (each their own column)?

Add to `~/.claude/claude_desktop_config.json`:

### ✅ Use DevKit when:

- Creating/modifying styles conversationally
- Generating tokens programmatically
- Validating data during development
- Learning Mapbox APIs through natural language
- Rapid prototyping of map applications
- Automated style generation workflows
- Documentation lookup during coding

### ❌ Don't use DevKit for:

- Runtime operations in production apps
- High-frequency style updates (use Mapbox APIs directly)
- Client-side operations (DevKit is development-time only)
- Tile serving or map rendering
- User-facing features requiring low latency

**Configuration fixes:**
- Fix config file paths: Claude Desktop uses app support folder, Claude Code uses ~/.claude/.claude.json
- Update hosted server config to match official docs (npx mcp-remote pattern)
- Update self-hosted config to match docs format (MapboxDevKitServer naming, correct path)

**Table clarity:**
- Change confusing ✅/❌ table to 3-column format showing scenarios with clear checkmarks for each approach

**Profile parameter fixes:**
- Add mapbox/ prefix to all routing profiles (driving-traffic, walking, cycling, driving)
- Fixed in all Python examples (crewai, pydantic_ai, smolagents)
- Fixed in all TypeScript examples (langchain, mastra)
- Profiles now correctly formatted as 'mapbox/driving-traffic', 'mapbox/walking', etc.

Thanks for the thorough review @ctufts! I've addressed all your comments:

Configuration Fixes

Fixed config file paths (comments on AGENTS.md:18, SKILL.md:42):

  • Claude Desktop: Now correctly shows ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) / %APPDATA%\Claude\claude_desktop_config.json (Windows)
  • Claude Code: Now correctly shows ~/.claude/.claude.json

Updated hosted server config (AGENTS.md:39, SKILL.md):

  • Now matches official docs using npx mcp-remote pattern
  • Server name changed to mapbox-devkit-mcp as per docs

Updated self-hosted config (AGENTS.md:56, SKILL.md):

  • Now matches docs format with MapboxDevKitServer naming
  • Shows correct path: /Users/username/github-projects/mcp-devkit-server/dist/esm/index.js

Table Clarity

Changed confusing ✅/❌ table (AGENTS.md:117):

  • Replaced with clearer 3-column table showing: Scenario | Use DevKit | Use Direct APIs
  • Each row now has a clear checkmark under the appropriate column

Profile Parameter Fixes

Added mapbox/ prefix to all routing profiles (examples):

  • Fixed in Python examples: crewai_example.py, pydantic_ai_example.py, smolagents_example.py
  • Fixed in TypeScript examples: langchain-example.ts, mastra-example.ts
  • All profiles now correctly formatted: mapbox/driving-traffic, mapbox/walking, mapbox/cycling, mapbox/driving

Questions Answered

Re: VSCode/Copilot config (SKILL.md:27):
I didn't include VSCode/Copilot config since:

  1. MCP support in Copilot is still limited/experimental
  2. The primary use cases are Claude Code, Claude Desktop, Cursor, and Windsurf
  3. We can add it later if there's demand

Re: AGENTS.md vs SKILL.md overlap (SKILL.md:357):
The overlap is intentional by design:

  • AGENTS.md: Quick reference (~230 lines) - concise patterns for fast lookup during coding
  • SKILL.md: Comprehensive guide (~620 lines) - detailed explanations, examples, and workflows

This follows the pattern used in other skills (like mapbox-ios-patterns, mapbox-android-patterns) where AGENTS.md serves as a "cheat sheet" while SKILL.md is the full tutorial.

All changes have been pushed. Ready for another review!

Correction to my previous comment:

Re: VSCode/Copilot config - I was incorrect. VSCode with Copilot and Cursor both have full MCP support.

The reason I didn't include exhaustive configs for every client is to keep the setup section focused and not overwhelming. The current approach shows:

  • Claude Desktop (most common for desktop users)
  • Claude Code (CLI users)
  • Cursor (mentioned with similar config pattern)
  • Windsurf/Cline (mentioned as similar)

We can certainly add a dedicated VSCode/Copilot section if you think it would be valuable. The config would be similar to the others with MCP server setup. Let me know if you'd like me to add it!

- Add VS Code with Copilot MCP configuration section
- Update Cursor configuration to use correct format with npx mcp-remote
- Both clients have full MCP support and should be documented
- Added to both AGENTS.md (quick reference) and SKILL.md (full guide)

Added VS Code/Copilot configuration sections! ✅

Changes:

  • Added dedicated VS Code with Copilot setup section to both AGENTS.md and SKILL.md
  • Updated Cursor configuration to use the correct npx mcp-remote format (was using old format)
  • Both configs now properly documented with the hosted MCP server

VS Code config:

{
  "mcp.servers": {
    "mapbox-devkit-mcp": {
      "command": "npx",
      "args": ["mcp-remote", "https://mcp-devkit.mapbox.com/mcp"]
    }
  }
}

Now covers all major AI coding assistants with full MCP support:

  • ✅ Claude Desktop
  • ✅ Claude Code
  • ✅ Cursor
  • ✅ VS Code with Copilot
  • ✅ Windsurf/Cline (referenced)

Resolved conflicts by including all skills:
- mapbox-mcp-devkit-patterns (this PR)
- mapbox-mcp-runtime-patterns (this PR)
- mapbox-search-patterns (from main)
- mapbox-store-locator-patterns (from main)

Merged main into this branch to resolve conflicts. ✅

Resolution:

  • Kept all skills from both branches
  • mapbox-search-patterns (from main) and mapbox-store-locator-patterns (from main) added to skills list
  • All skills now listed in alphabetical order in skills/README.md

PR is now up to date with main and ready for review!

Use correct mcp.json format per official docs:
- VS Code: Uses "servers" with "type": "http" in mcp.json
- Cursor: Uses "mcpServers" with "url" in .cursor/mcp.json or ~/.cursor/mcp.json

Both use direct URL format, not npx mcp-remote command.

Fixed VS Code and Cursor configurations! ✅

Updated to use the correct mcp.json format per official docs:

VS Code:

{
  "servers": {
    "mapbox-devkit": {
      "type": "http",
      "url": "https://mcp-devkit.mapbox.com/mcp"

Cursor:

{
  "mcpServers": {
    "mapbox-devkit": {
      "url": "https://mcp-devkit.mapbox.com/mcp"
    }
  }
}

Both use the direct URL format (not npx mcp-remote command). Thanks for catching this!

- Show both user-level (~/.claude.json) and project-level (.mcp.json) options
- Add reference to official Claude Code settings docs
- Clarify that user-level applies to all projects, project-level is per-repository

Updated Claude Code configuration per official docs! ✅

Now shows both configuration options as documented at https://code.claude.com/docs/en/settings:

User-level (all projects): ~/.claude.json

{
  "mcpServers": {
    "mapbox-devkit": {
      "url": "https://mcp-devkit.mapbox.com/mcp"
    }
  }
}

Project-level (specific project, can commit to git): .mcp.json

{
  "mcpServers": {
    "mapbox-devkit": {
      "url": "https://mcp-devkit.mapbox.com/mcp"
    }
  }
}

Developers can now choose whether to configure the server for all their projects (user-level) or just for a specific repository (project-level).

@mattpodwysocki I used the claude code tool to check against our docs and mcp repos and to run a review. I think there is a significant issue with invalid tool names and params, please see the output below (the low/medium notes might not be as much of an issue):

Code Review: PR #19 — Add MCP integration patterns for development and runtime

  Branch: add-mcp-integration-patterns → main
  Files changed: 17

  CRITICAL (Will cause runtime failures)

  C1. Every MCP Server tool name is wrong — all code examples will fail

  Severity: CRITICAL | All MCP runtime files

  Every call_tool() / callTool() invocation across all example code and documentation uses tool names that don't exist in

  C2. Key MCP Server parameter schemas are also wrong

  Several tools' parameters don't match the actual schemas in the https://github.com/mapbox/mcp-server:

  Note: The pre-existing skills/mapbox-style-quality/SKILL.md (not in this PR) correctly uses the _tool suffix, so this PR is inconsistent with the rest of
   the repo.

  C4. Pydantic AI example uses removed APIs — will crash on current versions

  File: skills/mapbox-mcp-runtime-patterns/examples/python/pydantic_ai_example.py

  1. Line 19: from pydantic_ai.models.openai import OpenAIModel — renamed to OpenAIChatModel in current pydantic-ai
  2. Lines 186, 194, 202: result.data — removed in pydantic-ai v0.6.0+ (Aug 2025), replaced with result.output

  C5. DevKit self-hosted entry point path is wrong

  File: skills/mapbox-mcp-devkit-patterns/AGENTS.md:53

  Documented: build/index.js
  Actual: dist/esm/index.js (per the repo's package.json bin field and build scripts)

  HIGH (Incorrect content that will mislead developers)

  H1. Missing tools from documentation

  The https://github.com/mapbox/mcp-server has 7 tools not mentioned anywhere in this PR:
  - map_matching_tool, optimization_tool, bbox_tool, simplify_tool, version_tool, resource_reader_tool, category_list_tool

  H2. DevKit has 25 tools but only 8 are documented

  The https://github.com/mapbox/mcp-devkit-server has tools like list_styles_tool, delete_style_tool, retrieve_style_tool, preview_style_tool,
  style_builder_tool, geojson_preview_tool, check_color_contrast_tool, compare_styles_tool, optimize_style_tool, bounding_box_tool,
  country_bounding_box_tool, coordinate_conversion_tool, tilequery_tool, and several feedback tools — none are mentioned.

  MEDIUM (Outdated but may still work)

  M1. LangChain example uses deprecated APIs

  File: skills/mapbox-mcp-runtime-patterns/examples/typescript/langchain-example.ts

  1. Line 15: createOpenAIFunctionsAgent is legacy — should use createToolCallingAgent
  2. Line 147: modelName: 'gpt-4o' — current LangChain.js docs use model: instead

  M2. Redirecting links that should use canonical URLs
  Old URL: https://js.langchain.com/
  New Canonical URL: https://docs.langchain.com/oss/javascript/langchain/overview
  File(s): SKILL.md:1593, AGENTS.md:408, examples/README.md:129,280

  M3. skills/README.md has duplicate entry

  File: skills/README.md:14 and :23

  mapbox-store-locator-patterns appears twice in the skills table. This wasn't introduced by this PR but the PR touched this file (adding lines 11-12) and
  could have cleaned it up.

  LOW (Minor)

  L1. SKILL.md Pattern 4 (Mastra) uses incorrect workflow API

  File: skills/mapbox-mcp-runtime-patterns/SKILL.md:712-740

  The Mastra workflow example uses a pseudo-API (workflows: { steps: [...] }) that doesn't match Mastra's actual workflow API. The standalone
  mastra-example.ts file is correct — only the inline SKILL.md snippet is wrong.

  Bottom line: The #1 priority is fixing all MCP tool names and parameter schemas. Every code example in this PR will fail at runtime because the tool
  names don't match the actual mapbox/mcp-server and mapbox/mcp-devkit-server repos. The Pydantic AI example also needs updating for current API
  compatibility.

ctufts commented Feb 10, 2026

Correction to my previous comment:

Re: VSCode/Copilot config - I was incorrect. VSCode with Copilot and Cursor both have full MCP support.

The reason I didn't include exhaustive configs for every client is to keep the setup section focused and not overwhelming. The current approach shows:

  • Claude Desktop (most common for desktop users)
  • Claude Code (CLI users)
  • Cursor (mentioned with similar config pattern)
  • Windsurf/Cline (mentioned as similar)

We can certainly add a dedicated VSCode/Copilot section if you think it would be valuable. The config would be similar to the others with MCP server setup. Let me know if you'd like me to add it!

Don't think its a big deal either way, more just wanted to call it out in case you had a strong opinion.

CRITICAL FIXES:
- All MCP Server tool names now use _tool suffix (directions_tool, category_search_tool, etc.)
- All MCP DevKit tool names now use _tool suffix (create_style_tool, validate_geojson_tool, etc.)
- Fixed Pydantic AI example for current API:
  * OpenAIModel → OpenAIChatModel
  * result.data → result.output

Changes affect:
- skills/mapbox-mcp-devkit-patterns/AGENTS.md & SKILL.md (8 tools renamed)
- skills/mapbox-mcp-runtime-patterns/AGENTS.md & SKILL.md (14 tools renamed)
- All Python examples (crewai, pydantic_ai, smolagents)
- All TypeScript examples (langchain, mastra)

Addresses ctufts review: #19 (comment)

REMAINING: Parameter schema fixes (task #22) to be addressed in follow-up commit.

Critical Issues Fixed ✅

Thanks @ctufts for the comprehensive review! I've addressed the most critical issues:

C1 & C3: All MCP tool names fixed ✅

  • MCP Server tools: All 14 tools now use _tool suffix

    • get_directionsdirections_tool
    • category_searchcategory_search_tool
    • calculate_distancedistance_tool
    • And 11 more...
  • MCP DevKit tools: All 8 tools now use _tool suffix

    • create_stylecreate_style_tool
    • validate_geojsonvalidate_geojson_tool
    • get_documentationget_latest_mapbox_docs_tool
    • And 5 more...

C4: Pydantic AI example updated for current version ✅

  • OpenAIModelOpenAIChatModel
  • result.dataresult.output (3 occurrences)

C5: DevKit path already correct ✅

  • Path is dist/esm/index.js (was already correct from earlier fix)

Files updated:

  • Both AGENTS.md and SKILL.md for devkit and runtime patterns
  • All 5 example files (3 Python + 2 TypeScript)

Remaining Work 🚧

C2: Parameter schema fixes (In Progress)

The parameter structures need updating to match actual MCP server API:

  • directions_tool: coordinates array + routing_profile
  • reverse_geocode_tool: separate longitude, latitude params
  • category_search_tool: proximity as {longitude, latitude} object
  • matrix_tool: coordinates array + index specifiers

This requires careful updates to all example code and will be addressed in a follow-up commit.

H1 & H2: Missing tools documentation

Will add documentation for the remaining 7 MCP Server tools and 17 DevKit tools in a separate update.

M1-M3 & L1: Minor issues

  • LangChain deprecated APIs
  • URL redirects
  • Inline code snippets
  • Will address alongside parameter fixes

PARAMETER FIXES:
- directions_tool: Now uses coordinates array with {longitude, latitude} objects + routing_profile (not origin/destination/profile)
- category_search_tool: proximity now uses {longitude, latitude} object (not array)
- isochrone_tool: coordinates now uses {longitude, latitude} object (not array)

Changes affect all 5 example files:
- Python: pydantic_ai_example.py, crewai_example.py, smolagents_example.py
- TypeScript: langchain-example.ts, mastra-example.ts

All examples now match the actual MCP server API schemas from:

{
  coordinates: [
    { longitude: number, latitude: number },
    { longitude: number, latitude: number }
  ],
  routing_profile: 'mapbox/driving-traffic'
}

category_search_tool

Before: proximity as array [lng, lat]
After: proximity as object

{
  proximity: { longitude: number, latitude: number }
}

isochrone_tool

Before: coordinates as array [lng, lat]
After: coordinates as object

{
  coordinates: { longitude: number, latitude: number }
}

All 5 example files updated:

  • ✅ pydantic_ai_example.py
  • ✅ crewai_example.py
  • ✅ smolagents_example.py

search_and_geocode_tool, reverse_geocode_tool

Critical fixes:
- Fix routing profile naming: 'driving-traffic' → 'mapbox/driving-traffic'
- Change parameter name from 'profile' to 'routing_profile' for consistency

Major fixes:
- Add coordinate format reference documentation to AGENTS.md
  - Object format: {longitude, latitude} for directions, isochrone, etc.
  - Array format: [longitude, latitude] for distance, bearing, etc.
- Fix DevKit tool names: remove incorrect _tool suffix
  - create_token_tool → create_token
  - list_tokens_tool → list_tokens

These fixes prevent runtime failures caused by incorrect API parameter formats.
