## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__changegamer__get_corpus` `mcp__changegamer__get_full_corpus` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__changegamer__get_corpus` `mcp__changegamer__get_payment_info` `mcp__changegamer__get_pricing` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_access`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (13)

Looks things up and changes nothing. Claude Code: allow.

### `get_access_info`

- The name "get_access_info" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return current access and pricing information for ChangeGamer resources.
```

### `get_article`

- The name "get_article" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_cluster`

- The name "get_cluster" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_corpus`

- The name "get_corpus" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "document": it reads documents.
- Tag untrusted-input: The description's first sentence says "return" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
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_corpus`

- The name "get_full_corpus" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `get_payment_info`

- The name "get_payment_info" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "crawl": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `get_pricing`

- The name "get_pricing" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "return" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
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_resource`

- The name "get_resource" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_stats`

- The name "get_stats" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_articles`

- The name "list_articles" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_resources`

- The name "list_resources" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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`

- The name "search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `search_resources`

- The name "search_resources" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `changegamer`:

```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",

    ],
    "ask": [
      "mcp__changegamer__check_access"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__changegamer__get_corpus`: private-data, untrusted-input
- `mcp__changegamer__get_full_corpus`: private-data
- `mcp__changegamer__get_pricing`: untrusted-input
- `mcp__changegamer__get_payment_info`: untrusted-input

```untrusted-server-text
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.
