What it is
An MCP server covering Cisco Webex's messaging API across 52 tools: the messaging surface itself, the org structures around it (rooms, teams, memberships, people), event plumbing through webhooks, and the enterprise pieces — room tabs, attachment actions and linked ECM folders. It runs over stdio or as an HTTP server.
Requirements
A Webex API token from developer.webex.com, in WEBEX_PUBLIC_WORKSPACE_API_KEY with the Bearer prefix stripped. Plan for renewal: the developer bearer token is short-lived and the README puts its lifetime at 12 hours, so a long-running deployment needs a token strategy rather than a paste. Node.js 18+, with 20+ recommended — below 18 there is no global fetch and the tools depend on it. WEBEX_API_BASE_URL overrides the endpoint, MCP_MODE selects stdio or http, and PORT sets the HTTP port, defaulting to 3001. The npm package name is webex-messaging-mcp-server (0.2.1), and a Docker image runs it as a non-root user. ENABLED_TOOLS narrows which tools load.
Setup effort
Run a container — build the image from the repository, then point your client at it
