Docusign MCP Integration for LangChain
Connect Docusign to LangChain through the local KosmoKrator MCP gateway with scoped tools, credentials, and write policy.
Connect Docusign 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.
