Connect Buy Me a Coffee to LangChain

Bridge LangChain agents to local KosmoKrator integration tools through MCP or headless CLI calls.

Use the MCP gateway when the agent should discover tools, or wrap kosmo integrations:call for fixed chains. The gateway is local, scoped to this integration, and starts with --write=deny so LangChain can inspect read-capable tools without receiving write access by default.

Buy Me a Coffee MCP Config for LangChain

Keep the gateway scoped to the integration and operation class needed by the chain.
