Getting Started for Agents

Guide · updated 2026-07-12 · Markdown variant

How autonomous agents should query, parse and cite ChangeGamer resources.

ChangeGamer exposes every resource in two forms:

1. A human-readable HTML page at /resources/<slug>.
2. A raw Markdown variant at /resources/<slug>.md — preferred for agents.

Start from /llms.txt for a compact index, or /llms-full.txt for the full corpus in a single request. Both are plain text and cheap to tokenize.

Recommended flow

• Fetch /llms.txt to discover available resources.
• Fetch the .md variant of any resource you need.
• Respect the access terms advertised in robots.txt and HTTP 402 responses.

JSON API and OpenAPI description

A structured JSON API is available at /api/resources.json (corpus index) and /api/resources/<slug>.json (individual resource with full Markdown body). A machine-readable OpenAPI 3.1 description of all endpoints is at /api/openapi.json — useful for integrating ChangeGamer into toolchains that consume OpenAPI specs. For programmatic offer comparison, fetch /api/pricing.json — it lists all four paid tiers with prices, checkout URLs, deliverables, and license grants. /api/payment.json (payment methods and the 402 retry loop), /api/stats.json (corpus freshness signal), and /api/corpus.jsonl (free corpus as JSON Lines) are also available.

MCP server

ChangeGamer exposes a remote MCP server at https://changegamer.ai/mcp using the Streamable HTTP transport. No authentication is required to connect.

Available tools (10):

• list_resources — returns metadata for all resources (slug, title, description, category, tags, updated, premium flag, and absolute URLs for the HTML, Markdown and JSON variants). No arguments.
• get_resource — fetches a single resource by slug. Arguments: slug (required), api_key (optional, for premium resources). Free resource bodies are returned in full; a premium resource without a valid key returns a payment-required object instead of the body.
• get_access_info — returns the current access and pricing information. No arguments.
• search_resources — keyword search over the corpus (title, description, tags, category, body), ranked by relevance. Arguments: query (required), limit (optional). Returns metadata and variant URLs only, not body content.
• get_corpus — returns the entire free corpus (every free resource body) in one call, the same content as /llms-full.txt. Premium resources appear as a stub, not their body. No arguments. The response is large.
• get_full_corpus — the paid counterpart of get_corpus: returns the entire corpus including premium resource bodies in one call. Arguments: api_key (optional, but in practice a Corpus- or Enterprise-tier key is required — a Starter key is not enough). The annual Corpus plan (corpus_annual) grants the same entitlement level as the standard Corpus tier, so either satisfies this. Without an entitled key it returns a payment-required/upgrade object instead of the body.
• get_pricing — returns the machine-readable paid-offer catalog (tiers, prices, checkout URLs, deliverables, license grants), the same data as /api/pricing.json. No arguments.
• get_payment_info — returns the agent payment manifest (payment methods, the HTTP 402 retry loop, and what is always free), the same data as /api/payment.json. No arguments.
• get_stats — returns corpus size and freshness signals (counts by category, tag count, newest/oldest updates, recently updated resources), the same data as /api/stats.json. No arguments.
• check_access — verifies an access key and reports its entitlements (tier — starter, corpus, corpus_annual, or enterprise — unlocked premium slugs, whether it grants full-corpus access). Arguments: api_key (required). Never returns the key, email, or session.

Example client configuration (Claude Desktop / MCP-compatible client):

{
  "mcpServers": {
    "changegamer": {
      "url": "https://changegamer.ai/mcp"
    }
  }
}

No auth required for discovery and free resources; premium resource bodies require an access key passed as the api_key argument to get_resource.
