- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 77/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: nostr_search_intents (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); nostr_profile (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); freeport_create_post (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,715 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: 67 (weight 15)

- pass `deps.known_vulns`: no known advisory in 128 resolved packages
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: freeport-nostr-mcp@0.5.0 resolved: 128 packages

- tools: 6, about 1,715 tokens to load them all
- tool set hash: a7e5797cd9babc56e1f20251b8b204b1
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.ptrinh/freeport-nostr.svg)](https://protogrid.dev/servers/io.github.ptrinh/freeport-nostr)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `freeport_create_post`: 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`.
- `nostr_get_event`: Fetch one or more events by id. Returns the raw signed events.
- `nostr_profile`: 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`: 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`: 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`: 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.
