## 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 2026-09-29.

- **Endpoint Security**: 46/100
  - 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 7 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 check failed: the endpoint is reachable over plaintext HTTP.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 75/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 932 tokens (~133/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 98/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 94% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (7)

### `get_verified_offer` (~157 tokens)

Read-only golf-offer.v1 using Chip's admission, exact-variant and live redirect gate. Requires a known 27aDay marketplace deal/product source UUID; search_products returns canonical IDs, not these source IDs. Explicit variant_id null means no selectable variant. Returns verified_offer, check_price or unavailable; unknown currency/ratings stay unknown. No account actions, click attribution or purchase is performed. Deployment may be disabled (503).

Input parameters:

- `canonical_product_id` (string, required): canonical product uuid, from search_products
- `source_id` (string, required): Known marketplace source UUID, not canonical product UUID
- `source_kind` (string, required)
- `variant_id` (string|null, required): Exact expected variant UUID or explicit null for nonvariant source

### `get_verified_offers` (~189 tokens)

Discover admitted marketplace sources for a canonical product ID from search_products, then verify each returned offer through Chip's exact-source commerce gate. If variant_id is omitted or null on a variant-bearing product, returns selection_metadata_not_offer options; unsourced specs stay unknown. Supply the exact variant UUID to get offers. Two sources checked per page within a bounded 16-source live window, use next_offset; this is not exhaustive catalog coverage or a stable snapshot. Results retain golf-offer.v1, including check_price and unknown currency. No member actions or click attribution. Deployment may be disabled (503).

Input parameters:

- `canonical_product_id` (string, required): Canonical product UUID from search_products
- `offset` (integer): Use response next_offset within the bounded live window; default 0
- `variant_id` (string|null): Exact variant UUID; null or omitted requests nonvariant offers or variant selection metadata

### `search_products` (~138 tokens)

Search the canonical golf equipment catalog by brand, category, or free text. Call this first to resolve a product_id for the other tools. Categories: drivers, iron-sets, wedges, putters, fairway-woods, hybrids, balls, bags, shoes, gloves, apparel, headcovers, complete-sets, accessories, tech, rangefinders, grips.

Input parameters:

- `brand` (string): brand name, case insensitive
- `category` (string): one of the categories listed above
- `limit` (integer): 1 to 100, default 25
- `q` (string): free text matched against the product name

### `get_product` (~84 tokens)

One product plus its enrichment_sources provenance rows. Every enriched field carries the source URL, confidence and checked_at it came from. Check enrichment_status before relying on specs: 'enriched' means model, release_year, msrp, description and specs are all sourced; 'partial' means some are missing.

Input parameters:

- `product_id` (string, required): canonical product uuid, from search_products

### `get_current_prices` (~64 tokens)

Latest stored advertised prices for one canonical product, with stock observations and stored affiliate links. These are not exact-variant verified buyable offers; use get_verified_offer when a marketplace source ID is known.

Input parameters:

- `product_id` (string, required): canonical product uuid, from search_products

### `get_price_history` (~75 tokens)

Dated price observations per retailer, where available. Coverage and refresh times vary by source. These rows are asking prices, not proof that a discount or stock state is current.

Input parameters:

- `days` (integer): 1 to 365, default 30
- `product_id` (string, required): canonical product uuid, from search_products

### `compare_prices` (~61 tokens)

Dated advertised retailer observations for one product plus min, max and median, and recorded 30 and 90 day lows. Coverage varies; these are not exact-variant verified purchase quotes.

Input parameters:

- `product_id` (string, required): canonical product uuid, from search_products

GolfData is an MCP server listed in the public MCP registry as co.golfdata/golfdata. Golf equipment catalog, live retailer prices and daily price history. Keyless search, free key. This page covers its hosted endpoint (https://golfdata.co/mcp).

### Is the GolfData MCP server safe to use?

GolfData scores 66 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the GolfData MCP server expose?

GolfData exposes 7 tools: get_verified_offer, get_verified_offers, search_products, get_product, get_current_prices, and 2 more. Their descriptions and schemas cost roughly 768 tokens of context every time the server is loaded.

### Does the GolfData MCP server require authentication?

No. We connected to GolfData without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the GolfData MCP server still maintained?

GolfData is still listed as active in the MCP registry. We last reached this channel on 29 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
