Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (14)
🟢list_resources
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.
Input Schema
{
"type": "object",
"properties": {},
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_resource(slug, api_key)
Fetch a ChangeGamer resource by slug. Free resources return full metadata and Markdown body. Premium resources require a valid api_key; without one a payment-required object is returned.
Input Schema
{
"type": "object",
"properties": {
"slug": {
"type": "string",
"description": "Resource slug (e.g. \"getting-started\")"
},
"api_key": {
"type": "string",
"description": "Access key for premium resources"
}
},
"required": [
"slug"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_access_info
Return current access and pricing information for ChangeGamer resources.
Input Schema
{
"type": "object",
"properties": {},
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢search_resources(query, limit)
Search the ChangeGamer corpus by keyword. Ranks resources by relevance across title, description, tags, category, and body, and returns metadata plus HTML/Markdown/JSON URLs (no body content). Use this to find resources before fetching them with get_resource.
Input Schema
{
"type": "object",
"properties": {
"query": {
"type": "string",
"description": "Search keywords, e.g. \"retrieval augmented generation\" or \"mcp auth\""
},
"limit": {
"type": "integer",
"minimum": 1,
"maximum": 50,
"description": "Maximum number of results (default 10)."
}
},
"required": [
"query"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_corpus
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.
Input Schema
{
"type": "object",
"properties": {},
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_full_corpus(api_key)
Return the ENTIRE corpus including premium resource bodies in one document — the keyed deliverable of the Corpus/Enterprise license. Requires a Corpus- or Enterprise-tier api_key (a Starter key unlocks premium resources but NOT the corpus file); without an entitled key a payment-required/upgrade object is returned. The free, premium-stubbed version is get_corpus.
Input Schema
{
"type": "object",
"properties": {
"api_key": {
"type": "string",
"description": "Corpus/Enterprise license key (cg_...)"
}
},
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_pricing
Return the full paid-offer catalog: every tier with price, currency, interval, checkout URL, what it unlocks, deliverables, and license grant — plus the free layer and premium slug list. Same data as /api/pricing.json.
Input Schema
{
"type": "object",
"properties": {},
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_payment_info
Return the agent payment manifest: every way to pay (HTTP 402 + Bearer key, MCP, Stripe checkout, x402, RSL per-crawl), the exact 402 retry loop, what is always free, and the recommended path per use case. Same data as /api/payment.json.
Input Schema
{
"type": "object",
"properties": {},
"$schema": "http://json-schema.org/draft-07/schema#"
}🟡get_stats
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
{
"type": "object",
"properties": {},
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢list_articles
List all ChangeGamer editorial guides (always free, separate from the licensable corpus): cluster-first hub/spoke graph with every article's title, search intent, word count, takeaways count and variant URLs. No body content — fetch bodies with get_article.
Input Schema
{
"type": "object",
"properties": {},
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_article(slug)
Fetch one ChangeGamer guide (editorial article) by slug as full Markdown with its metadata header. Always free — never part of the paid corpus. Use list_articles to discover slugs.
Input Schema
{
"type": "object",
"properties": {
"slug": {
"type": "string",
"description": "Article slug (e.g. \"rag-in-production\")"
}
},
"required": [
"slug"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢search(q, limit)
Keyword search across ALL ChangeGamer content (resources and editorial guides) with server-side ranking: term hits in title weigh most, then tags, then description. Returns ranked rows with type, slug, title and .md URL (no body content). Use get_resource/get_article to fetch winners.
Input Schema
{
"type": "object",
"properties": {
"q": {
"type": "string",
"description": "Search query — one or more keywords"
},
"limit": {
"type": "integer",
"minimum": 1,
"maximum": 25,
"description": "Max results (default 10)"
}
},
"required": [
"q"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_cluster(cluster_id)
Fetch one ChangeGamer guide cluster (topic bundle) from the free editorial layer: pillar metadata, every sub-article with variant URLs, and the pillar’s full Markdown body. Use list_articles to discover cluster ids.
Input Schema
{
"type": "object",
"properties": {
"cluster_id": {
"type": "string",
"description": "Cluster id, e.g. \"rag-in-production\""
}
},
"required": [
"cluster_id"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢check_access(api_key)
Verify an access key and report what it unlocks. Returns valid:true/false; when valid, the tier, when it was created, the premium slugs it unlocks, and that it grants the gated /api/corpus.full.jsonl + get_full_corpus deliverable. Never returns the key, email, or Stripe session. Use this to confirm a freshly-purchased key works before relying on it.
Input Schema
{
"type": "object",
"properties": {
"api_key": {
"type": "string",
"description": "Access key to verify (cg_...)"
}
},
"required": [
"api_key"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
