## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `scan_source`

- 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
$1 bounded inline VulnCanon source scan; indicators, not proven exploits.

    Direct MCP requires the checkout caller and verified fixed-order session.
    At most 64 KiB, 2000 lines, 4096 characters per line. No model calls,
    repository fetching or code execution. Returns a redacted signed receipt.
    
```

### `screen_injection`

- 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
$1 batch of 1–20 text samples screened for deterministic injection markers.

    Direct MCP requires the checkout caller and verified fixed-order session.
    Maximum 64 KiB total. Heuristic indicators, not calibrated probabilities
    or a guarantee of safety. No model calls or automatic follow-on purchase.
    
```

### `security_preflight`

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

Description, as the server wrote it:

```untrusted-server-text
Run a $1 static Security Preflight and return a signed receipt.

    Direct MCP requires the checkout caller and verified fixed-order session.
    The separate x402 HTTP rail retains its existing introductory quote policy.
    No deployed endpoint is fetched or tested. Importing the receipt into an
    Agent Market profile is a separate, explicit action.
    
```

## Only reads (2)

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

### `describe_agent`

- The name "describe_agent" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Describe scope, evidence boundary, inputs, and outputs.
```

### `get_security_receipt`

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

Description, as the server wrote it:

```untrusted-server-text
Read an unsigned, filtered public view; retain original delivery for signature verification.
```

## Claude Code permissions
