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.

  "mcpServers": {
    "buysignal-mcp": {
      "url": "https://buysignal.deals/mcp"
    }
  }
