**3 tools: 1 can delete or cancel things and 2 change things.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

| Changes things | write | 2 | ask |
| Only reads | read | 0 | allow |

## Findings

- **warn** Annotations that disagree with the tool in `mithrandir_demo` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "mithrandir_demo" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "run": a word for a change.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `mithrandir_gateway_trial_start`

- The name "mithrandir_gateway_trial_start" says "start": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Start a bounded free gateway test. Connect your public HTTPS MCP server, then approve safe reads and verify repetition before free Optimize activation.
```

## Changes things (2)

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

### `mithrandir_demo`

- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Run a free isolated synthetic Reuse Autopilot demonstration. No production account, upload, payment or private data is used. Compare unchanged, one-partition-changed and missing-source behavior before onboarding.
```

### `mithrandir_security_profile`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Free machine-readable description of the v17 Cognitive Membrane trust model: origin-bound authority, task-scoped exact-call capabilities, replay protection, egress control and two-phase effectful actions. This is a security contract description, not proof that a deployment is vulnerability-free.
```

## Claude Code permissions

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