Connect Jenkins to CrewAI

Expose KosmoKrator integrations to CrewAI workers as scoped local tools.

Wrap kosmo integrations:call for specific tasks or connect workers to a local MCP gateway. The gateway is local, scoped to this integration, and starts with --write=deny so CrewAI can inspect read-capable tools without receiving write access by default.

Jenkins MCP Config for CrewAI

Use per-worker integration scopes to avoid giving every worker every tool.

Why Use KosmoKrator Here

Scoped tools

Expose only Jenkins instead of a broad multi-service tool list.

Local credentials

Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.

Write policy

Start read-only, then opt into ask or allow for trusted workspaces.
