Paystack MCP Integration for LangChain
Connect Paystack to LangChain through the local KosmoKrator MCP gateway with scoped tools, credentials, and write policy.
Connect Paystack 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.
Paystack MCP Config for LangChain
Keep the gateway scoped to the integration and operation class needed by the chain.

Expose only Paystack instead of a broad multi-service tool list.
Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.
