Category Search and Retrieval
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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability81
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1532 tokens (~109/item across 14 items; 14 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 Management97
- Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (50% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 14 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 15 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

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 →
check_access Check access key ~117
Verify an access key and report what it unlocks. Returns valid:true/false; when valid, the tier, when it was created, the premium slugs it unlocks, and whether it grants the gated /api/corpus.full.jsonl + get_full_corpus deliverable (corpus, corpus-annual and enterprise tiers only). Never returns the key, email, or Stripe session. Use this to confirm a freshly-purchased key works before relying on it.
| Name | Type | Req | Description |
|---|---|---|---|
| api_key | string | yes | Access key to verify (cg_...) |
| Name | Type | Req | Description |
|---|---|---|---|
| corpus_version | string | yes | – |
| tier | string | – | – |
| valid | boolean | yes | – |
No examples provided.
get_access_info Get access info ~21
Return current access and pricing information for ChangeGamer resources.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_article Get guide ~88
Fetch one ChangeGamer guide (editorial article) by slug as full Markdown with its metadata header, plus a second JSON block with the canonical URL, citation/bibtex and the reference resources it builds on. Always free — never part of the paid corpus. Use list_articles or search to discover slugs.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Article slug (e.g. "rag-in-production") |
No output schema declared.
No examples provided.
get_cluster Get guide cluster ~74
Fetch one ChangeGamer guide cluster (topic bundle) from the free editorial layer: cluster metadata, every member article as a compact row with its Markdown URL, and the pillar’s full Markdown body. Use list_articles to discover cluster ids.
| Name | Type | Req | Description |
|---|---|---|---|
| cluster_id | string | yes | Cluster id, e.g. "rag-in-production" |
No output schema declared.
No examples provided.
get_corpus Get free corpus ~129
Return the entire free corpus as one document (every free resource title, description, canonical URL, and full Markdown body) — the same content as /llms-full.txt. Premium resources appear as a stub with a purchase link, not their body. Use this to ingest everything in a single call; the response is large. Optional `category` returns only that category's resources (smaller result). Size without category: about 890 KB.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Only resources in this category (case-insensitive): Guide, Policy, Reference, Meta. Omit for the whole corpus. |
No output schema declared.
No examples provided.
get_full_corpus Get full corpus (licensed) ~110
Return the ENTIRE corpus including premium resource bodies in one document — the keyed deliverable of the Corpus/Enterprise license. Requires a Corpus-, Corpus-annual- or Enterprise-tier api_key (a Starter key unlocks premium resources but NOT the corpus file); without an entitled key a payment-required/upgrade object is returned. The free, premium-stubbed version is get_corpus. Size: about 900 KB.
| Name | Type | Req | Description |
|---|---|---|---|
| api_key | string | – | Corpus/Enterprise license key (cg_...) |
No output schema declared.
No examples provided.
get_payment_info Get payment info ~70
Return the agent payment manifest: every way to pay (HTTP 402 + Bearer key, MCP, Stripe checkout, x402, RSL per-crawl), the exact 402 retry loop, what is always free, and the recommended path per use case. Same data as /api/payment.json.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| methods | array | yes | – |
| recommended | string | yes | – |
No examples provided.

Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| offers | array | yes | – |
No examples provided.
get_resource Get resource ~95
Fetch a ChangeGamer resource by slug. Free resources return full metadata, the Markdown body, cited source URLs and a ready-made citation/bibtex. Premium resources require a valid api_key; without one a payment-required object is returned. An unknown slug returns did_you_mean suggestions.
| Name | Type | Req | Description |
|---|---|---|---|
| api_key | string | – | Access key for premium resources |
| slug | string | yes | Resource slug (e.g. "getting-started") |
No output schema declared.
No examples provided.
get_stats Get corpus stats ~81
Return corpus stats: total/free/premium counts, per-category counts, tag count, newest/oldest update dates, the 10 most recently updated resources, feed URLs — plus an editorial block (guide count, words, newest publish) merged at runtime from the static articles index. A small freshness/size signal to poll before deciding whether to re-ingest.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| corpus_version | string | yes | – |
| newest_updated | string | yes | – |
| premium | number | yes | – |
| total | number | yes | – |
No examples provided.
list_articles List guides ~174
List ChangeGamer editorial guides (always free, separate from the licensable corpus): compact rows (slug, title, cluster, kind, order, description, updated, Markdown URL), one page at a time, plus the cluster list. `cluster` narrows to one topic; `full: true` returns the complete index with search intents, takeaways and variant URLs. No body content — fetch bodies with get_article. Size with full: true: about 710 KB.
| Name | Type | Req | Description |
|---|---|---|---|
| cluster | string | – | Only this cluster id (see `clusters`). |
| full | boolean | – | true = the complete /api/articles.json index; other arguments ignored. |
| limit | integer | – | Rows per page (default 30). |
| offset | integer | – | Rows to skip (default 0); pass next_offset. |
No output schema declared.
No examples provided.
list_resources List resources ~112
List all ChangeGamer resources with metadata and absolute URLs. Returns slug, title, description, category, tags, updated date, premium flag, and HTML/Markdown/JSON variant URLs. No body content. Optional `category` and `premium` filters narrow the list; without them every resource is returned.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Only resources in this category (case-insensitive): Guide, Policy, Reference, Meta. |
| premium | boolean | – | true = only premium resources, false = only free ones. |

search_resources Search resources ~124
Search the ChangeGamer corpus by keyword. Every word must match the title, tags, category, description or (as a last resort) the body; results rank title > tags > category > description > body, the same order as the site search. Returns metadata plus HTML/Markdown/JSON URLs (no body content). Use this to find resources before fetching them with get_resource.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum number of results (default 10). |
