For other services, search the MCP registry API:
```http
GET https://registry.modelcontextprotocol.io/v0/servers?q=<search_term>
```
Each result includes a `remotes` array with the exact server URL to use.
### Important: Check blocks first
Before using `run_mcp_tool`, always check if the platform already has blocks for the service
using `find_block`. The platform has hundreds of built-in blocks (Google Sheets, Google Docs,
Google Calendar, Gmail, etc.) that work without MCP setup.
Only use `run_mcp_tool` when:
- The service is in the known hosted MCP servers list above, OR
- You searched `find_block` first and found no matching blocks
**Never guess or construct MCP server URLs.** Only use URLs from the known servers list above
or from the `remotes[].url` field in MCP registry search results.
