v0.8.0

[0.8.0]

Breaking Changes

Changed

• Upgraded to casual-llm >= 0.6.0.
• Change config structure to match casual-llm new client/model class structure
• Improved logging across the framework.
• ModelFactory now accepts a Config object in the constructor and get_model() takes only a model name. Previous API: ModelFactory() + get_model(name, model_config, client_configs). New API: ModelFactory(config) + get_model(name).
• API key resolution is now handled by casual-llm via ClientConfig.name. Lookup order: explicit api_key in config > {CLIENT_NAME.upper()}_API_KEY env var > provider default env var (e.g. OPENAI_API_KEY, ANTHROPIC_API_KEY).
• Provider strings are passed directly to casual-llm's ClientConfig instead of being mapped to an enum. casual-llm handles string-to-enum coercion internally.
• McpClientConfig.provider type relaxed from Literal["openai", "ollama", "anthropic"] to str for forward compatibility with new providers.

Added

• casual-mcp migrate-config CLI command to migrate legacy config files (with provider/endpoint in models) to the new clients/models format.

Removed

• PROVIDER_MAP dict (no longer needed since casual-llm accepts provider strings).
• API_KEY_ENV_VARS dict and manual os.getenv() API key lookup (now handled by casual-llm).
• Auto-migration of legacy config at load time. Use casual-mcp migrate-config instead.

v0.3.0

Split the McpToolChat chat method and chat api endpoint into:

• chat: for handling list of chat messages
• generate: for simple user prompt with optional session

Updated the README to reflect the changes and improve the usage examples

v0.2.2

Turns out that FastMCP added support for multi server clients at the same time that I released v0.1.0 which was nice of them 😅

Not much point in having my own implementation so have removed the MultiServerMcpClient and instead using the Client from FastMCP in McpToolChat.

Also I decided to align the servers config with the one they implemented so there is a change to the config.

Changes:

• Removed MultiServerMcpClient in favour of FastMCP Client's multi server support
• Refactored McpToolChat to use FastMCP Client
• Updated servers config structure to match that of FastMCP
• Renamed config from config.json to casual_mcp_config.json
• Improved README
• Some other minor improvements

v0.1.0

Initial Release (0.1.0)

• Plug-and-play multi-server tool orchestration
• Prompt templating with Jinja2
• Configurable via JSON
• CLI and API access
• Extensible architecture
