Available components
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. How we score → Why this is hard to score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS check failed: the endpoint is reachable over plaintext HTTP. See how to fix → View diagnostics → Fail
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability75
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management43
- Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage98
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 94% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the GolfData MCP server?
GolfData is a hosted endpoint at https://golfdata.co/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
compare_prices ~61
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.
| Name | Type | Req | Description |
|---|---|---|---|
| product_id | string | yes | canonical product uuid, from search_products |
No output schema declared.
No examples provided.
get_current_prices ~64
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.
| Name | Type | Req | Description |
|---|---|---|---|
| product_id | string | yes | canonical product uuid, from search_products |
No output schema declared.
No examples provided.
get_price_history ~75
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.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | 1 to 365, default 30 |
| product_id | string | yes | canonical product uuid, from search_products |
No output schema declared.
No examples provided.
get_product ~84
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.
| Name | Type | Req | Description |
|---|---|---|---|
| product_id | string | yes | canonical product uuid, from search_products |
No output schema declared.
No examples provided.
get_verified_offer ~157
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).
| Name | Type | Req | Description |
|---|---|---|---|
| canonical_product_id | string | yes | canonical product uuid, from search_products |
| source_id | string | yes | Known marketplace source UUID, not canonical product UUID |
| source_kind | string | yes | – |
| variant_id | string|null | yes | Exact expected variant UUID or explicit null for nonvariant source |
No output schema declared.
No examples provided.
get_verified_offers ~189
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).
| Name | Type | Req | Description |
|---|---|---|---|
| canonical_product_id | string | yes | 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 |
No output schema declared.
No examples provided.
search_products ~138
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 |
