It provides read-only access to data including tool categories, customer lists with proof levels, company stacks, and comparative analyses, all sourced from public evidence without requiring an API key.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http usedby-mcp https://www.usedby.ai/mcp
