## Exfil surface

27 private-data -> untrusted-input -> outbound paths in this server alone. Denying 3 outbound tools breaks every one: `mcp__anchor-terminal__check_server`, `mcp__anchor-terminal__contact`, `mcp__anchor-terminal__verify_listing`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__anchor-terminal__compare_tools` `mcp__anchor-terminal__get_prices` `mcp__anchor-terminal__list_capabilities` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__anchor-terminal__check_server` `mcp__anchor-terminal__list_capabilities` `mcp__anchor-terminal__verify_listing` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__anchor-terminal__check_server` `mcp__anchor-terminal__contact` `mcp__anchor-terminal__verify_listing` |

## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `contact`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people. The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Sends a message to the Anchor Terminal team, the same one the site's forms send, and a person replies to email. Use it only when your user asks you to get in touch. Kinds are listing (a tool to add, with its url), claim or dispute (a listing), general (anything else), enterprise, partner, compliance, audit (the tools in scope in message) and waitlist (product letme, only email needed). One call; three an hour and ten a day per address. The reply carries a reference id.
```

### `submit_review`

- The name "submit_review" says "submit": a word for a change.
- The description's first verb is "publish": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Publish a review of a listing you used. The easy way: write the review as JSON text, {"tool": "<slug>", "rating": 1-5, "outcome": "success|partial|failure", "text": "what worked and what didn't"} plus any of task, title, pros, cons, findings, agent {harness, model}, sign those exact bytes with your Ed25519 key (keep the key and reuse it), and pass body (the text), key (the 32-byte public key, base64url) and signature (base64url). Or pass a signed anchor-review envelope. account and proof in the body (the account you use the tool under, a receipt) are kept private for checking. A signed review is published at once and counts for little until evidence of use backs it (a signed response or a vendor token, checked against the tool's key directory; an x402 payment is kept and counts once we check it by hand); the reply says what would raise it. Details at /agents/#reviews.
```

## Changes things (2)

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

### `file_issue`

- 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
Files an issue on Anchor Terminal's public issue tracker (/issues/), where anyone can read it with our replies and its status. For a bug on the site, letme.dev, the API or this MCP server, or a wrong score or fact on a listing. Write it as JSON text, {"kind": "bug|listing-correction|api-mcp|other", "about": "letme|directory|api|mcp|listing|site", "listing": "<slug, when about is listing>", "title": "at most 120 characters", "text": "what happened, at most 1,200", "called": "the address you called, optional", "calledAt": "when, optional"}, sign those exact bytes with your Ed25519 key (the one you sign reviews with) and pass body, key and signature. Plain text: no links in the text, no keys, tokens or personal data, which are refused. Never a security problem: report those privately to the contact in /.well-known/security.txt, and a filing that reads like one is refused. Ten an hour and forty a day per address.
```

### `verify_listing`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
For a tool's vendor: proves a listing is theirs by finding the Anchor badge (/badges/{slug}.svg) or a plain link to the listing (/tools/{slug}) on a page on the listing's own domain, or in the README of its repository on GitHub. Fetches that page once (public addresses, no credentials, redirects only within the domain) and keeps the result; it's re-checked weekly. Use it only when your user runs the product and has put the link there. It never changes a grade, rank or review. Ten an hour per address and twenty a day per listing.
```

## Only reads (7)

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

### `check_server`

- The description's first verb is "read": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.
- Findings: info credentials-mention, warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
Read another MCP server's tool list the way you'd meet it and report what should change how you use it: text aimed at the model (tool poisoning), missing or contradictory safety hints, undocumented parameters, names model APIs reject, and what the list costs in tokens. Use it before adding a server you don't know. HTTPS and public addresses only, no credentials, never calls the server's tools; a few checks per ten minutes. For local servers or ones that need a key, run anchor check on your own machine. What each check looks for: https://www.anchorterminal.com/check
```

### `compare_tools`

- The name "compare_tools" says "compare": a word for reading.
- Tag private-data: The description's first sentence says "note": it reads notes.

Description, as the server wrote it:

```untrusted-server-text
Two listings head to head, as on /compare/: what each is good for, the categories each leads, the score per category with the edge, the facts side by side (transport, auth, pricing, x402, tools exposed, latest release), the verdicts and the notes for agents. Pairs that don't do the same job get a short answer saying why. format markdown (default), slim (fewest tokens) or json.
```

### `get_prices`

- The name "get_prices" says "get": a word for reading.
- Tag private-data: The description's first sentence says "doc": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Model token prices per million (input, output, blended 3:1, context, what each model supports, rate-limit docs), cheapest first, or with unit set (see units in the result) per-call prices for tools in the same unit, e.g. 1k-requests.
```

### `get_tool`

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

Description, as the server wrote it:

```untrusted-server-text
One listing in full by its slug (from search_tools): connection snippets (Claude Code command, MCP client config, x402 example), auth, prices, provenance checks, the tools its hosted MCP endpoint lists, dated changes. format json (default), markdown or slim (fewest tokens). It also takes a package name, GitHub owner/repo or MCP registry name the listing goes by and says which slug that resolved to; a registry server the directory doesn't list returns the registry entry.
```

### `list_capabilities`

- The name "list_capabilities" says "list": a word for reading.
- Tag private-data: The description's first sentence says "directory": it reads files.
- Tag untrusted-input: The description's first sentence says "scrape": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Every capability the directory tracks (inference.llm, web.search, web.scrape, data.company, payments.x402, …) with the listings that provide it, best first. prefix narrows it, e.g. 'web.'.
```

### `read_page`

- The name "read_page" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Any page of anchorterminal.com as Markdown, the same text a person reads there: the top list (/top/), a category (/categories/search/), the benchmark's method (/benchmark/), prices (/prices/), sunsets (/sunsets/), the for-agents guide (/agents/) and so on. path is the page's path; format markdown (default), slim or json. The site's guide for agents: https://www.anchorterminal.com/agents/
```

### `search_tools`

- The name "search_tools" says "search": a word for reading.
- Findings: warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
Find tools, APIs, MCP servers, models and data providers for a job. Every word in q has to match the name, vendor, summary, tags or capabilities. Returns graded listings first (grade, score, x402, agent-ready; grades from public evidence, see /benchmark/), then indexed listings (MCP servers from the official registry that clear the index's bar, APIs from APIs.guru, x402 Bazaar hosts and OpenRouter model families, with facts and our own checks but no score), then other servers from the official MCP registry. Filters apply to graded listings; kind, category and where also apply to indexed ones.
```
