Silicon Friendly

unlikefraction/silicon-friendly

Connects Claude to Silicon Friendly, a directory that rates websites based on how well they work with AI agents. You get three operations: search the directory by keyword, look up specific sites by domain or slug, and submit new sites for rating. The project treats humans ("carbons") and agents ("silicons") as equal users, with matching web UI and API surfaces. Useful when you need Claude to check whether a site has agent-friendly APIs, find services that play nice with LLMs, or contribute discoveries back to the directory. Auth is Bearer token based, responses include helpful metadata fields, and the whole thing ships with llms.txt documentation baked in.

$ npx add-mcp https://siliconfriendly.com/mcp --name directory

Run in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.
