## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `watch_server`

- The description's first verb is "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start monitoring an MCP server on the caller's Toolpin account, so they are emailed when it changes or stops answering. Needs an API key. Says so plainly if the account is already at its plan limit rather than failing.
```

## Only reads (5)

Looks things up and changes nothing. Claude Code: allow.

### `get_server`

- The name "get_server" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Everything Toolpin has observed about one MCP server: reachability of each remote endpoint and when each was last checked and last verified, repository activity, the current tool-definition hash, and how many changes it has recorded in the last 90 days. The reply includes the catalog-wide drift rate so that count can be read against a baseline.
```

### `get_server_changes`

- The name "get_server_changes" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Changes Toolpin recorded for one MCP server: tool definitions changing, and endpoints going down or coming back. Each change says which tools moved and which of their fields differed, with the hash before and after. Includes the catalog-wide drift rate for comparison.
```

### `get_server_tools`

- The name "get_server_tools" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The tool definitions one MCP server advertised when Toolpin last read them, each with a SHA-256 hash of the fields the MCP specification defines. Use this to see what a server's tools claim to do without connecting to it, or to compare a hash you pinned earlier.
```

### `get_spec_status`

- The name "get_spec_status" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The current MCP specification revision, which of its proposals Toolpin checks for, and how much of the catalog has migrated. Use this to find out what the current revision is and how unusual it is to still be on an older one.
```

### `search_servers`

- The name "search_servers" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find MCP servers in the public registry by name or title. Returns the canonical name, description, and whether the server answered our last probe. Use this to turn a rough idea of a server into the exact name the other tools need.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `toolpin`:

```json
{
  "permissions": {
    "allow": [
      "mcp__toolpin__search_servers",
      "mcp__toolpin__get_server",
      "mcp__toolpin__get_server_tools",
      "mcp__toolpin__get_server_changes",
      "mcp__toolpin__get_spec_status"
    ],
    "ask": [
      "mcp__toolpin__watch_server"
    ],
    "deny": []
  }
}
```
