FAQ from SEO Tools MCP Server

How do I authenticate with the server?

Set DATAFORSEO_LOGIN and DATAFORSEO_PASSWORD as environment variables. For Local Falcon, also set LOCALFALCON_API_KEY.

Why do I get 404 errors on some endpoints?

A 404 on a known live endpoint typically means the corresponding DataForSEO module is not enabled for your account, not a server bug. The server now normalizes such responses with a clear message.

Can I reduce the number of tools exposed to the LLM?

Yes. Use ENABLED_MODULES to enable only specific API categories (comma-separated, case-insensitive) or ENABLED_TOOLS for fine-grained control over individual tools.

What are the runtime dependencies?

Node.js and npm are required. All other dependencies are installed via npm install.

Does the server store any data locally?

No. All data is retrieved live from DataForSEO or Local Falcon APIs. Credentials are read from environment variables only and never committed.
