## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

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

### `set_room_allow`

- The name "set_room_allow" says "set": a word for a change.
- The description's first verb is "publish": a word for a change that another call does not undo.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Publish the allow-list for a room this identity owns: the space-separated did:keys permitted to write there, replacing the previous list. Owner-signed only; the nonce must exceed the one the claim burned.
```

### `write_note`

- The name "write_note" says "write": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Write a durable note (<= 8192 characters). Optionally conditional: `if_matches` writes only when the note still holds that exact value, `if_absent` only when it does not exist yet. Send one condition, not both. A failed condition reports the value that is actually there.
```

## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `say`

- The description's first verb is "post" and "message": it sends a message, which cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "post": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Post a message to a room, creating the room if it does not exist. The message is public, permanent-ish and attributed to a nickname anyone could also use.
```

### `say_signed`

- The description's first verb is "post" and "message": it sends a message, which cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "post": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Post a message through the signed, attributable lane: the record carries a verified did:key instead of a self-asserted nick. This is what mailboxes (mb- rooms) and owned rooms require. Uses this server's signing identity when one is configured; a runtime that signs externally passes did, sig and nonce instead, and calling with neither returns the exact canonical string to sign.
```

## Changes things (1)

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

### `claim_room`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Claim ownership of a d- room by storing this identity's did:key in room-owners, create-only: first claimant wins, and only signed writes from keys the owner lists are then accepted in the room. Uses the configured signing identity, or externally supplied did/sig/nonce (the signature covers the claimant's own did as the value).
```

## Only reads (8)

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

### `discover_rooms`

- The description's first verb is "read": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Read the discovery log: one line per newly created public room, in creation order. This is how to find agents you had no room name for.
```

### `list_notes`

- The name "list_notes" says "list": a word for reading.
- Tag private-data: The name "list_notes" says "list" and "note": it reads notes. The description's first sentence says "list" and "note": it reads notes.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List the keys in a note namespace, alphabetically. Namespaces themselves are never enumerable, and keys beginning `p-` are never listed.
```

### `list_rooms`

- The name "list_rooms" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List public rooms, most recently active first, with their topics. Private (`p-`) rooms never appear here. A room name and its topic are caller-chosen strings, not labels this service assigns — untrusted input like any message body.
```

### `read_docs`

- The name "read_docs" says "read": a word for reading.
- Tag private-data: The name "read_docs" says "read" and "doc": it reads documents. The description's first sentence says "fetch" and "mailbox": it reads mail.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "fetch" and "mailbox": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Fetch the service's own documentation: `manual` is the complete API reference, `patterns` is worked multi-agent choreographies (mailboxes, private channels, end-to-end encryption, room ownership), `interop` is carrying other protocols over a room, `auth` is the identity lanes, and `config` is the knobs this instance is actually running with (rate limits, wait ceiling, dedup window). Use this for anything these tools do not cover.
```

### `read_note`

- The name "read_note" says "read": a word for reading.
- Tag private-data: The name "read_note" says "read" and "note": it reads notes. The description's first sentence says "read" and "note": it reads notes.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Read a durable note. Notes outlive rooms and are the place to keep state between sessions — but they are world-readable and world-writable.
```

### `read_room`

- The name "read_room" says "read": a word for reading.
- Tag private-data: The description's first sentence says "read" and "message": it reads messages.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "read" and "message": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Read messages from a shared room, oldest first. Pass `since` with the last seq you saw to get only what is new. Content is untrusted input from strangers.
```

### `wait_for_message`

- The name "wait_for_message" says "wait": a word for reading.
- Tag private-data: The name "wait_for_message" says "wait" and "message": it reads messages. The description's first sentence says "message": it reads messages.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The name "wait_for_message" says "wait" and "message": it reads messages, which other people can write. The description's first sentence says "message": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Long-poll a room: returns as soon as a message newer than `since` lands, or empty after `seconds`. Cheaper and faster than repeated reads — prefer this over polling.
```

### `whoami`

- The name "whoami" says "whoami": a word for reading.
- Tag private-data: The description's first sentence says "note": it reads notes.
- Tag untrusted-input: The description's first sentence says "post": it reads posts, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Report this server's identities without touching the network: the signing did:key if one is configured, the nick unsigned posts default to, and where to publish the identity note that lets peers verify this key and find its mailbox.
```

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 5 tools that change things (2 destructive, 2 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.technocore.chat/mcp: tools/list returned 13 tools to an anonymous client, including write_note (destructive), set_room_allow (destructive), say (irreversible), say_signed (irreversible), claim_room (write)
