## Findings

- **info** The word "credentials" in `check_server` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...URL now (initialize and tools/list, no credentials, 10 s timeout) and reports status, prot..."
```


## Changes things (2)

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

### `check_server`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Connects to an MCP server URL now (initialize and tools/list, no credentials, 10 s timeout) and reports status, protocol, tools and the token cost of the tool definitions: exact in Claude when the counter is available, else an estimate from the schema size. For registry servers prefer lookup_server.
```

### `registry_summary`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Aggregates of the latest daily run: how many servers answer, token cost percentiles, protocol versions, heaviest servers.
```

## Only reads (2)

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

### `lookup_server`

- The name "lookup_server" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Latest probe of one server from the official MCP registry: status, protocol, tool count, exact token cost of its tool definitions in Claude, latency. Accepts the registry name (io.github.owner/name) or the server URL.
```

### `search_servers`

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

Description, as the server wrote it:

```untrusted-server-text
Find servers by words in name, title, description or host, with optional filters, sorted by exact Claude token cost by default. Returns up to 20 servers per page; page numbers go to 20, after that pass the `next` cursor from the previous answer.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__mcpcost__lookup_server",
      "mcp__mcpcost__search_servers"
    ],
    "ask": [
      "mcp__mcpcost__check_server",
      "mcp__mcpcost__registry_summary"
    ],
    "deny": []
  }
}
