## Only reads (3)

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

### `prism_help`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns connection instructions: how to set the upstream MCP server (X-Prism-Upstream header or ?upstream= query param), the query-param config keys for header-less clients, how destinations and the borrowed-token model work, and example client configs. Start here if you are an agent discovering Prism for the first time.
```

### `prism_info`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns Prism's service identity and runtime state: version, transport, public URL, capture default, and the number of MCP sessions currently being traced. Use this to confirm which Prism deployment you are talking to and whether it is healthy before configuring an upstream.
```

### `prism_ping`

- The name "prism_ping" says "ping": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns {"pong": true, "time": <unix seconds>} plus an optional echo of the 'echo' argument. Use to verify connectivity through the gateway before pointing it at an upstream MCP server.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__prism__prism_info",
      "mcp__prism__prism_ping",
      "mcp__prism__prism_help"
    ],
    "ask": [],
    "deny": []
  }
}
```
