Using as an MCP Server

The MCP Server can be run in two modes: stdio (for local testing) or http (for networked access). To start the server, use the following commands:

Run in stdio mode (default):

searxng-mcp --transport "stdio"

Run in HTTP mode:

searxng-mcp --transport "http"  --host "0.0.0.0"  --port "8000"

Deploy MCP Server as a Service

The ServiceNow MCP server can be deployed using Docker, with configurable authentication, middleware, and Eunomia authorization.

Using Docker Run

docker pull knucklessg1/searxng-mcp:latest

docker run -d \
  --name searxng-mcp \
  -p 8004:8004 \
  -e HOST=0.0.0.0 \
  -e PORT=8004 \
  -e TRANSPORT=http \
  -e AUTH_TYPE=none \
  -e EUNOMIA_TYPE=none \
  -e SEARXNG_URL=https://searxng.example.com \
  -e SEARXNG_USERNAME=user \
  -e SEARXNG_PASSWORD=pass \
  -e USE_RANDOM_INSTANCE=false \
  knucklessg1/searxng-mcp:latest

For advanced authentication (e.g., JWT, OAuth Proxy, OIDC Proxy, Remote OAuth) or Eunomia, add the relevant environment variables:

docker run -d \
  --name searxng-mcp \
  -p 8004:8004 \
  -e HOST=0.0.0.0 \
  -e PORT=8004 \
  -e TRANSPORT=http \
  -e AUTH_TYPE=oidc-proxy \
  -e OIDC_CONFIG_URL=https://provider.com/.well-known/openid-configuration \
  -e OIDC_CLIENT_ID=your-client-id \
  -e OIDC_CLIENT_SECRET=your-client-secret \
  -e OIDC_BASE_URL=https://your-server.com \
  -e ALLOWED_CLIENT_REDIRECT_URIS=http://localhost:*,https://*.example.com/* \
  -e EUNOMIA_TYPE=embedded \
  -e EUNOMIA_POLICY_FILE=/app/mcp_policies.json \
  -e SEARXNG_URL=https://searxng.example.com \
  -e SEARXNG_USERNAME=user \
  -e SEARXNG_PASSWORD=pass \
  -e USE_RANDOM_INSTANCE=false \
  knucklessg1/searxng-mcp:latest

Using Docker Compose

Create a docker-compose.yml file:

services:
  searxng-mcp:
    image: knucklessg1/searxng-mcp:latest
    environment:
      - HOST=0.0.0.0
      - PORT=8004
      - TRANSPORT=http
      - AUTH_TYPE=none
      - EUNOMIA_TYPE=none
      - SEARXNG_URL=https://searxng.example.com
      - SEARXNG_USERNAME=user
      - SEARXNG_PASSWORD=pass
      - USE_RANDOM_INSTANCE=false
    ports:
      - 8004:8004

For advanced setups with authentication and Eunomia:

services:
  searxng-mcp:
    image: knucklessg1/searxng-mcp:latest
    environment:
      - HOST=0.0.0.0
      - PORT=8004
      - TRANSPORT=http
      - AUTH_TYPE=oidc-proxy
      - OIDC_CONFIG_URL=https://provider.com/.well-known/openid-configuration
      - OIDC_CLIENT_ID=your-client-id
      - OIDC_CLIENT_SECRET=your-client-secret
      - OIDC_BASE_URL=https://your-server.com
      - ALLOWED_CLIENT_REDIRECT_URIS=http://localhost:*,https://*.example.com/*
      - EUNOMIA_TYPE=embedded
      - EUNOMIA_POLICY_FILE=/app/mcp_policies.json
      - SEARXNG_URL=https://searxng.example.com
      - SEARXNG_USERNAME=user
      - SEARXNG_PASSWORD=pass
      - USE_RANDOM_INSTANCE=false
    ports:
      - 8004:8004
    volumes:
      - ./mcp_policies.json:/app/mcp_policies.json

Run the service:

docker-compose up -d
