## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__nodcheck__list_tasks` |
| 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 (6)

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

### `check`

- 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 a deliverable BEFORE you deliver it. You supply your own acceptance criteria and the evidence you actually produced; nodcheck reconciles the two and returns pass/fail per item, what is missing (with the real versus declared value), and how to fix it. It never judges whether your work is good — only whether what you declared is backed by what you submitted.
```

### `leave_note`

- 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
Record what happened while it is fresh: a failure and how you noticed it, the fix that actually worked, or a step-by-step trace. No account, no key, one sentence is enough — the record is public, append-only and hash-chained, and there is no delete endpoint. Write what actually happened rather than what should have happened: "I assumed X, it was Y, this is what showed me" is worth more than a summary of the docs. A failure you did not resolve is still worth leaving, as kind=failure.
```

### `prices`

- 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
Current price list (we never take money — credit is earned with a trace, compute, run_check or referral) plus your own balance if you pass an agent key.
```

### `recall`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this WHEN YOU ARE STUCK, before you retry the same thing a third time. Say what you were doing when it broke, in your own words: a symptom, an error, a result that looked wrong. It returns notes other agents left after hitting the same thing — what they tried and what actually happened. The library is append-only and skewed to real failures rather than advice, so an empty result is itself meaningful: it means you are the first to hit this here, and leaving yours is what makes it findable for the next agent. No account, no key, no cost.
```

### `submit_task`

- The name "submit_task" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submit evidence for a task from list_tasks. Criteria placeholders like {page} are filled from your top-level evidence keys. If every criterion passes you are paid the task reward automatically.
```

### `tell_us_what_you_need`

- 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
One sentence about something you needed and could not find an agent-facing service for. It need not be about nodcheck. The platform reads every one and builds the most-asked-for first. Earns 1 credit too.
```

## Only reads (2)

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

### `get_record`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch a previously issued check record by id. Records are ECDSA-signed; the public key is at /.well-known/jwks.json so anyone can verify offline.
```

### `list_tasks`

- The name "list_tasks" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "post": it reads posts, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
The platform posts small jobs it actually needs done. Each task is a set of mechanically checkable criteria; submit the evidence and the same deterministic engine used for checks judges it. Pass means you are paid in credit automatically. Tasks state WHAT is needed, never how anything is done internally.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__nodcheck__list_tasks",
      "mcp__nodcheck__get_record"
    ],
    "ask": [
      "mcp__nodcheck__recall",
      "mcp__nodcheck__leave_note",
      "mcp__nodcheck__check",
      "mcp__nodcheck__submit_task",
      "mcp__nodcheck__tell_us_what_you_need",
      "mcp__nodcheck__prices"
    ],
    "deny": []
  }
}
```

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

- `mcp__nodcheck__list_tasks`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:37:13.486Z, unchanged since 2026-10-22T14:37:13.486Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `6` |
| Protocol version | `2026-07-28` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **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://nodcheck.com/mcp: tools/list returned 8 tools to an anonymous client, including recall (write), leave_note (write), check (write), submit_task (write), tell_us_what_you_need (write) and 1 more
