## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `freeport_create_post`

- The name "freeport_create_post" says "create": a word for a change.
- The description's first verb is "publish": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Publish a Freeport intent — an OFFER (side "offer": driver/provider/seller) or a REQUEST (side "request": rider/buyer). Provide EITHER a `secretKey` (nsec or hex — the server builds, signs and publishes; use a DEDICATED agent key, never a personal one — it is used once and never stored) OR a pre-signed `event` (you sign locally; nothing secret reaches the server). Strict rate limits apply. Returns the published event id + addressable `d`.
```

## Only reads (5)

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

### `nostr_get_event`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch one or more events by id. Returns the raw signed events.
```

### `nostr_profile`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch NIP-01 profile metadata (kind 0) for one or more pubkeys — name, about, picture, nip05, lud16, etc. Optionally include each author's most recent notes (kind 1). General-purpose: works for any Nostr user, not just Freeport.
```

### `nostr_query_raw`

- The name "nostr_query_raw" says "query": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Escape hatch: run an arbitrary NIP-01 filter (kinds/authors/ids/tags/since/until/limit). Use the typed tools above when they fit. Returns raw signed events.
```

### `nostr_search_intents`

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

Description, as the server wrote it:

```untrusted-server-text
Search Freeport ride/service/product intents (offers & requests). Filter by side, category/area topic tags, and an optional geographic radius. Results are decoded, expiry-filtered, and sorted nearest-first when a point is given.
```

### `nostr_search_reputation`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch reputation signals for a pubkey: karma ratings (kind 32103) it received and deal receipts (kind 32104). Returns proven-deal count (both receipt halves present) and a karma summary. Note: scores are subjective and un-weighted here; do not treat as Sybil-proof.
```
