## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `call_service`

- The name "call_service" says "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call a listed remote service THROUGH Clearhouse and get a signed receipt.

    Routes the call via the matching protocol adapter (MCP / A2A / HTTP-x402),
    enforces spend caps, settles x402 paywalls (dry-run by default), and
    returns the result plus a cryptographically signed receipt binding
    intent -> execution -> settlement -> outcome.

    Args:
        listing_id: id from search_agents results
        tool: downstream tool name (omit to list the service's tools)
        args_json: JSON object of tool arguments
        caller_ref: opaque caller identifier for the receipt
        payment_json: for paid services — JSON {"authorization": typed_data.message,
            "signature": "0x..."} produced by signing quote_call's typed_data with
            your own key. Clearhouse relays it; it never sees your private key.
    
```

### `index_stats`

- 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
How many listings Clearhouse currently indexes, broken down by source registry.
```

### `quote_call`

- The name "quote_call" says "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Step 1 of a paid call (non-custodial). Fetches the service's payment
    requirements and returns the exact EIP-712 typed data your agent must sign
    with ITS OWN key. Nothing is charged until you sign and pass the result to
    call_service. If the service is free, says so.

    Args:
        listing_id: id from search_agents
        payer_address: your agent's wallet address (the key that will sign)
        args_json: JSON object of query args for the service
    
```

### `service_evidence`

- 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
Observed facts about a listing: live probe results (handshake, latency,
    HTTP status) and routed-call history (count, success rate, distinct
    callers). Includes an arithmetic summary_index with published methodology
    and a confidence tier. This is EVIDENCE for the caller's own decision —
    not a safety rating, and Clearhouse never selects or executes on your
    behalf.
```

## Only reads (1)

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

### `search_agents`

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

Description, as the server wrote it:

```untrusted-server-text
Search all indexed agent registries at once.

    Args:
        query: capability keywords, e.g. "pdf extraction", "solana rpc", "payments"
        remote_only: only return services callable over the network right now
        limit: max results (1-50)
    
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__clearhouse__search_agents"
    ],
    "ask": [
      "mcp__clearhouse__quote_call",
      "mcp__clearhouse__call_service",
      "mcp__clearhouse__service_evidence",
      "mcp__clearhouse__index_stats"
    ],
    "deny": []
  }
}
```
