What is the Flagsmith MCP Server?

Connect your Flagsmith account to any AI agent to control feature releases and remote configurations through natural conversation.

What you can do

  • Flag Management — Retrieve default flag states and remote configuration values for any environment instantly.
  • Identity Control — Fetch specific flags and traits for user identities or identify new users with custom traits to test personalized experiences.
  • Environment Admin — Create new environments within projects and fetch full configuration documents for local evaluation modes.
  • Dynamic Updates — Update flag values (single or batch) and manage segment overrides using the Admin API for rapid iteration.
  • Local Evaluation — Access the entire environment configuration document for high-performance SDK integrations.

How it works

  1. Subscribe to this server
  2. Enter your Flagsmith Environment Key or Admin API Key
  3. Start managing your feature lifecycle from Claude, Cursor, or any MCP-compatible client

Who is this for?

  • Developers — check flag states and user traits directly from the code editor to debug feature logic without switching contexts.
  • Product Managers — toggle features, manage rollouts, and update remote configs without touching the dashboard.
  • DevOps & SREs — automate environment creation and manage segment overrides through simple natural language commands.

FAQ

Frequently asked questions

01

Can I retrieve flags for a specific user identity?

Yes. Use the get_identity_flags tool by providing the user's identifier. The agent will return all flags and traits associated with that specific identity in the environment.

02

How do I update multiple feature flags at once?

You can use the update_flag_v2 tool for batch changes. Provide the environment key and a JSON payload containing the updates you wish to apply simultaneously.

03

Is it possible to create a new environment via the agent?

Yes, using the create_environment tool. You will need to provide a name for the environment and the target Project ID. This requires a valid Flagsmith Admin API Key.

04

How does Google ADK connect to MCP servers?

Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.

05

Can ADK agents use multiple MCP servers?

Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.

06

Which Gemini models work best with MCP tools?

Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
