## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 49/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS not yet verified: we couldn't determine whether a plaintext access path exists.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 75/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1388 tokens (~173/item across 8 items; 6 tools + 2 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 89/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 66% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (6)

### `nostr_search_intents` (~251 tokens)

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.

Input parameters:

- `includeExpired` (boolean)
- `limit` (integer)
- `near` (object): Filter & sort by distance from this point.
- `relaySideGeohash` (boolean): Also narrow at the relay via a #g cover of the radius. Only effective if posts carry geohash-prefix tags; off by default.
- `relays` (array): Override the relay set for this call (ws/wss URLs, max 10). Defaults to the server relays.
- `side` (string): offer = drivers/providers/sellers; request = riders/buyers; any = both
- `since` (integer): Only events created at/after this unix-seconds time.
- `topics` (array): Topic `t` tags to require (category/subcategory/area keys, e.g. "vn_hanoi", "ridesharing").
- `until` (integer): Only events created at/before this unix-seconds time.

### `nostr_search_reputation` (~130 tokens)

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.

Input parameters:

- `limit` (integer)
- `pubkey` (string, required): Subject pubkey (hex) to look up reputation for.
- `relays` (array): Override the relay set for this call (ws/wss URLs, max 10). Defaults to the server relays.

### `nostr_get_event` (~62 tokens)

Fetch one or more events by id. Returns the raw signed events.

Input parameters:

- `ids` (array, required)
- `relays` (array): Override the relay set for this call (ws/wss URLs, max 10). Defaults to the server relays.

### `nostr_profile` (~145 tokens)

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.

Input parameters:

- `pubkeys` (array, required): Hex pubkeys to fetch profiles for.
- `recentNotes` (integer): If >0, also fetch up to this many recent text notes (kind 1) per pubkey.
- `relays` (array): Override the relay set for this call (ws/wss URLs, max 10). Defaults to the server relays.

### `nostr_query_raw` (~157 tokens)

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.

Input parameters:

- `authors` (array)
- `ids` (array)
- `kinds` (array)
- `limit` (integer)
- `relays` (array): Override the relay set for this call (ws/wss URLs, max 10). Defaults to the server relays.
- `since` (integer)
- `tags` (object): Tag filters, e.g. {"t":["vn_hanoi"],"g":["w3gv"]}. Keys are single tag letters.
- `until` (integer)

### `freeport_create_post` (~415 tokens)

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`.

Input parameters:

- `d` (string): Stable id to republish/replace an existing post; defaults to random.
- `event`: A complete, signed Nostr event (kind 32101/32102). Use instead of secretKey to keep keys off the server.
- `expiresInMinutes` (integer): How long the post stays live (default 720). Max 30 days.
- `geohashes` (array): Geohashes for location-scoped discovery. Each is expanded into all its prefixes (precision 1-6) so radius searches at any precision match.
- `market` (string): Market key, e.g. "rideshare" or "service".
- `payload` (object): Intent payload (from/to/location, payment, etc.) per the freeport://protocol resource.
- `relays` (array)
- `schema` (string): Payload schema, e.g. "rideshare/1" or "service/1".
- `secretKey` (string): nsec or 64-hex private key. Used transiently to sign; never stored. Omit if passing a pre-signed `event`.
- `side` (string): offer = provider/seller/driver; request = buyer/rider.
- `title` (string)
- `topics` (array): Topic `t` tags (area/category), e.g. ["vn_hanoi","vn_hanoi_ridesharing"].
- `window` (object)
