## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `build_brain`

- 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
Compile an agent file into a deterministic, content-addressed brain.
    content = the file as a string; format = verdigraph_genome |
    claude_project_export | openai_assistant | prompt_list | auto.
    Returns brain_id, content_hash, node/edge counts, the 9-invariant
    firing report, and provenance. Identical bytes always produce the
    identical brain_id (VB1). include_document=true returns the full
    graph.
```

### `detect_format`

- 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
Detect which supported agent-file format the content is
    (verdigraph_genome, claude_project_export, openai_assistant,
    prompt_list) before building.
```

### `verify_brain`

- 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
Machine-check a cognition claim: recompute the brain from the
    submitted content and compare against the claimed brain_id and/or
    content_hash. valid=true iff every claimed identifier matches the
    deterministic recomputation (VB3).
```

## Only reads (1)

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
Return capabilities and input contract.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__verdigraph__describe_agent"
    ],
    "ask": [
      "mcp__verdigraph__build_brain",
      "mcp__verdigraph__verify_brain",
      "mcp__verdigraph__detect_format"
    ],
    "deny": []
  }
}
```
