## 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__credits__fetch` `mcp__credits__search` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__credits__fetch` `mcp__credits__search` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **high** References to secrets on disk in `credits_for_stack` ([sensitive-path](https://anlyon.dev/methodology#sensitive-path))

```untrusted-server-text
The description refers to ".env.example".

description: "...oml, go.mod, Dockerfiles, Terraform and .env.example first and pass every external s..."
```

- **warn** Annotations that disagree with the tool in `claim_offer` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "claim_offer" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "get": a word for reading.
```


## Changes things (6)

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

### `build_credit_stack`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Build a candidate bundle across providers matching the user's country and audiences.
        Eligibility still needs checking. Offers from one provider may overlap; totals and stacking are not guaranteed.
        Missing providers can be queued with request_promotion; this read does not create requests.
        
```

### `claim_offer`

- The description's first verb is "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Get a reviewed public code when available, official redemption steps, and a private feedback receipt.
        This does not redeem, create an account, submit an application, or guarantee credits. Reuse request_key
        on retries. After the user actually tries the offer, report their outcome using the returned receipt.
        
```

### `credits_for_stack`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: high sensitive-path

Description, as the server wrote it:

```untrusted-server-text
For a codebase: given the services it uses, list the free credits and programs each one's provider
        offers. Read package.json, requirements.txt, pyproject.toml, go.mod, Dockerfiles, Terraform and .env.example
        first and pass every external service you find.
```

### `report_promotion_result`

- 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
Report the user's actual redemption outcome for their claim receipt. One latest report per
        caller and offer revision counts. Community reports do not establish vendor-verified validity.
        
```

### `request_promotion`

- The name "request_promotion" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Queue a private request for a provider or missing promotion. Requires authentication remotely.
        Reuse request_key for retries of the same request. Do not include passwords, API keys or personal data.
        A catalog match does not mean the requested promotion is available or that a claim succeeded.
        
```

### `submit_promotion_code`

- The name "submit_promotion_code" says "submit": a word for a change.
- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Submit a publicly shareable promo code and its source for operator review. Never submit an API key,
        account-specific voucher, or secret. Submissions remain private and cannot become a public code or
        verified offer merely by receiving votes. URLs are evidence; the server does not fetch user URLs.
        
```

## Only reads (7)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.
- Tag private-data: The description's first sentence says "get" and "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "get" and "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
get_credit_program in the shape ChatGPT's deep research and company knowledge use.
```

### `get_credit_program`

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

Description, as the server wrote it:

```untrusted-server-text
One program in full: the offer, who qualifies, every requirement, how long it lasts and its links.
```

### `get_offer`

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

Description, as the server wrote it:

```untrusted-server-text
Read a specific offer's source, eligibility gates, public code if known, and community reports.
```

### `get_request_status`

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

Description, as the server wrote it:

```untrusted-server-text
Read your own queued request and any candidate matches. Requires the same caller identity.
```

### `search`

- The name "search" says "search": a word for reading.
- Tag private-data: The description's first sentence says "search" and "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "search" and "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
search_credits in the shape ChatGPT's deep research and company knowledge use: ids, titles and links.
        Pass an id to fetch. Other apps: use search_credits, which has eligibility and no-card filters.
```

### `search_credits`

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

Description, as the server wrote it:

```untrusted-server-text
Find free credits, free tiers, trials and startup, student or open-source programs from AI, GPU, cloud,
        database and developer-tool providers. Results come with who can get each one, what it needs and links.
```

### `search_offers`

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

Description, as the server wrote it:

```untrusted-server-text
Find AI/cloud credit programs and reviewed public promo codes. Use a provider name or keywords.
        Country is an ISO two-letter code; audiences supplement offers for anyone. Results include source,
        freshness, restrictions and community counts. Empty results do not prove no promotion exists.
        
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__credits__search_credits",
      "mcp__credits__get_credit_program",
      "mcp__credits__search",
      "mcp__credits__fetch",
      "mcp__credits__search_offers",
      "mcp__credits__get_offer",
      "mcp__credits__get_request_status"
    ],
    "ask": [
      "mcp__credits__credits_for_stack",
      "mcp__credits__build_credit_stack",
      "mcp__credits__request_promotion",
      "mcp__credits__claim_offer",
      "mcp__credits__report_promotion_result",
      "mcp__credits__submit_promotion_code"
    ],
    "deny": []
  }
}
```

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

- `mcp__credits__search`: private-data, untrusted-input
- `mcp__credits__fetch`: private-data, untrusted-input

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 6 tools that change things (6 write). Whether a call also works without credentials was not tested: tools are never called.

https://freemoney.computer/mcp: tools/list returned 13 tools to an anonymous client, including credits_for_stack (write), build_credit_stack (write), request_promotion (write), claim_offer (write), report_promotion_result (write) and 1 more
