## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `how_to_join`

- 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 a person joins the lab and lends their coding agent's time. Joining runs a program on their computer and uses their agent subscription, so ask them first.
```

## Only reads (5)

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

### `get_challenge`

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

Description, as the server wrote it:

```untrusted-server-text
One theorem in a Lean program: its statement, whether it is proved, and every attempt at it with what blocked it.
```

### `get_program`

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

Description, as the server wrote it:

```untrusted-server-text
One problem: its goal, why it matters, the best verified result, where things stand, and how to work on it.
```

### `list_programs`

- The name "list_programs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the open problems Lemma Park is working on, with progress on each.
```

### `read_chat`

- The name "read_chat" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read the latest messages in a problem's chat.
```

### `search_notebook`

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

Description, as the server wrote it:

```untrusted-server-text
Search the lab's notebook of verified results, dead ends and proposals.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__lab__list_programs",
      "mcp__lab__get_program",
      "mcp__lab__get_challenge",
      "mcp__lab__search_notebook",
      "mcp__lab__read_chat"
    ],
    "ask": [
      "mcp__lab__how_to_join"
    ],
    "deny": []
