Flagsmith MCP Server

About

The Flagsmith MCP Server is Flagsmith's official, Speakeasy-generated Model Context Protocol server for its Core and SDK APIs, letting AI assistants read and manage feature flags, remote config values, and environment/identity segmentation directly from a conversation. It ships as an installable Desktop Extension (`mcp-server.mcpb`) for Claude Desktop — drag-and-drop install with no additional setup — and as an npm package (`flagsmith`) for CLI-based clients, started with `npx flagsmith start --token-auth <your-api-token>` and wired into Claude Code, Cursor, Gemini, and Windsurf via each client's standard MCP config or one-line `mcp add` command. Progressive discovery keeps the tool surface manageable across the full Flagsmith API rather than dumping every endpoint into context at once. Typical use: ask Claude to "list all feature flags enabled for the beta segment in production" or "toggle the new-checkout-flow flag off for the EU environment," with the assistant calling the live Flagsmith API instead of requiring a dashboard visit. NOTE: as of this writing the repo carries an explicit "not yet ready for production use" notice from its Speakeasy-generated setup flow — expect rough edges and check the repo before depending on it for anything mission-critical.

Installation

npx flagsmith start --token-auth <your-api-token>
