# toolpin

toolpin reports whether another MCP server answered, what tools it advertised, and whether those definitions changed. Use it to inspect agent dependencies or investigate a server change.

## What it does

Search the public registry with `search_servers`. For a specific server, `get_server` reports observed endpoint reachability, check times, repository activity, and recorded changes. `get_server_tools` returns the definitions the server advertised with hashes of specification-defined fields; `get_server_changes` lists definition changes and endpoints going down or coming back. Toolpin compares those fields daily.

\`watch_server` monitors a server through your Toolpin account and emails you when it changes or stops responding. Reading requires no key; `watch_server` and a higher limit require a key in the `Authorization: Bearer` header. Tool descriptions are the server author’s claims, not claims verified by Toolpin. It provides no safety rating, so its results cannot establish that a tool is safe or does what its description says.

The service uses stateless Streamable HTTP. Add it to Claude Code with `claude mcp add --transport http toolpin https://toolpin.dev/mcp`; Codex, Cursor, GitHub Copilot, and Gemini CLI also have install configurations.

## Requirements
- Remote server: `https://toolpin.dev/mcp`

```bash
claude mcp add --transport http toolpin https://toolpin.dev/mcp
```

```bash
codex mcp add toolpin --url https://toolpin.dev/mcp
```

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "toolpin": {
            "url": "https://toolpin.dev/mcp"
        }
    }
}
```

### GitHub Copilot

```bash
gemini mcp add -t http toolpin https://toolpin.dev/mcp
```

## When to use it
- find MCP servers in the public registry
- check whether a remote server endpoint responded
- inspect advertised tool definitions and their hashes
- track changes to a server’s tools or availability
- receive email when a monitored server changes or stops responding

## Example prompts
- Find MCP servers for working with Git in the public registry.
- Check the advertised tools and recorded changes for MCP server `example-server`.
- Monitor MCP server `example-server` and email me about changes or outages.
