plane-mcp-server

The server securely loads API keys and workspace slugs from environment variables, preventing hardcoding. It explicitly checks for the presence of required environment variables (`PLANE_API_KEY`, `PLANE_WORKSPACE_SLUG`). Input schemas are defined for tools, and additional runtime checks are performed on critical arguments like `project_id`. The `create-issue` and `update-issue` tools include robust logic to handle potentially malformed `assignees` input from LLMs, reducing the risk of invalid data being sent to the Plane API. All external API calls are made using `fetch` with proper error handling. No `eval` or other dynamic code execution is observed.
