- Click the "Install Now" button to open the FastMCP connection interface (the place where the MCP server connection and environment variables are configured).
- In the FastMCP connection interface find the environment / secrets section and add the OFREP endpoint URL: set OPENFEATURE_OFREP_BASE_URL (or OFREP_BASE_URL) to the base URL provided by your OFREP-compatible flag service (e.g., https://flags.example.com). (openfeature.dev)
- Obtain a bearer token or API key from your flag management system: sign in to your flag provider → open Account / API / Integrations / Service tokens → create a new token (give it only the permissions needed for flag evaluation) → copy the token.
- If the provider issues a bearer token, paste it into OPENFEATURE_OFREP_BEARER_TOKEN (or OFREP_BEARER_TOKEN).
- If the provider issues an API key, paste it into OPENFEATURE_OFREP_API_KEY (or OFREP_API_KEY). (openfeature.dev)
- If the FastMCP interface accepts inline auth fields for an individual call, you may instead provide the token there (auth.bearer_token or auth.api_key) for one-off tests; otherwise prefer the environment variables above so the MCP can use them for all calls. (glama.ai)
- (Optional) Instead of environment variables, you can create a local config file at ~/.openfeature-mcp.json with the OFREP settings and point the MCP to it with OPENFEATURE_MCP_CONFIG_PATH. Example file contents:
{
"OFREP": {
"baseUrl": "https://flags.example.com",
"bearerToken": "",
"apiKey": ""
}
} (openfeature.dev) - Save the FastMCP connection settings in the interface. Use the MCP's OFREP flag-evaluation tool (ofrep_flag_eval) or run a small test evaluation to confirm the base URL and token/api key are correct. If the test fails, verify the exact endpoint and token permissions in your flag provider's docs. (openfeature.dev)
- Secure the credentials: treat tokens/API keys as secrets (do not commit them to source control). If available, store them in your platform’s secrets manager and reference them from FastMCP rather than pasting into plaintext fields.
