Changes things 1Claude Code: ask
  • check_accessVerify an access key and report what it unlocks.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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.

  • get_access_infoReturn current access and pricing information for ChangeGamer resources.No findings

    Why it is in this group

    • The name "get_access_info" says "get": a word for reading.
    Description, as the server wrote it
    Return current access and pricing information for ChangeGamer resources.
  • get_articleFetch one ChangeGamer guide (editorial article) by slug as full Markdown with its metadata header.No findings

    Why it is in this group

    • The name "get_article" says "get": a word for reading.
    Description, as the server wrote it
    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.
  • get_clusterFetch 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.No findings

    Why it is in this group

    • The name "get_cluster" says "get": a word for reading.
    Description, as the server wrote it
    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.
  • get_corpusReturn 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.Reads private dataReads text others writeNo findings

    Why it is in this group

    • The name "get_corpus" says "get": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "return" and "document": it reads documents.
    • untrusted-inputThe description's first sentence says "return" and "url": it reads web pages, which anyone can write.
    Description, as the server wrote it
    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.
  • get_full_corpusReturn the ENTIRE corpus including premium resource bodies in one document — the keyed deliverable of the Corpus/Enterprise license.Reads private dataNo findings

    Why it is in this group

    • The name "get_full_corpus" says "get": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "return" and "document": it reads documents.
    Description, as the server wrote it
    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.

    Description, as the server wrote it
    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.

    • untrusted-inputThe description's first sentence says "return" and "url": it reads web pages, which anyone can write.
    Description, as the server wrote it
    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.
  • get_resourceFetch a ChangeGamer resource by slug.No findings

    Why it is in this group

    • The name "get_resource" says "get": a word for reading.
    Description, as the server wrote it
    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.
  • get_statsReturn 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 bl…No findings

    Why it is in this group

    • The name "get_stats" says "get": a word for reading.
    Description, as the server wrote it
    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.
  • list_articlesList 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, takea…No findings

    Why it is in this group

    • The name "list_articles" says "list": a word for reading.
    Description, as the server wrote it
    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.
  • list_resourcesList all ChangeGamer resources with metadata and absolute URLs.No findings

    Why it is in this group

    • The name "list_resources" says "list": a word for reading.
    Description, as the server wrote it
    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.
  • search_resourcesSearch the ChangeGamer corpus by keyword.No findings

    Why it is in this group

    • The name "search_resources" says "search": a word for reading.
    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged outbound.

Reads private data2
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write3
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

  • WarnThe whole server

    The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://changegamer.ai/mcp: tools/list returned 14 tools to an anonymous client, including check_access (write)

    What this check looks for

Install

Pinned to version 1.0.2. Values in angle brackets are yours to fill in.

claude mcp add --transport http changegamer https://changegamer.ai/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__changegamer__list_resources",
      "mcp__changegamer__get_resource",
      "mcp__changegamer__get_access_info",
      "mcp__changegamer__search_resources",
      "mcp__changegamer__get_corpus",
      "mcp__changegamer__get_full_corpus",
      "mcp__changegamer__get_pricing",
      "mcp__changegamer__get_payment_info",
      "mcp__changegamer__get_stats",
      "mcp__changegamer__list_articles",
      "mcp__changegamer__get_article",
      "mcp__changegamer__search",
      "mcp__changegamer__get_cluster"
    ],
    "ask": [
      "mcp__changegamer__check_access"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as changegamer. Review it before you use it.
