## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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.

### `closing_soon`

- 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
PRO. Posted grants for your keywords closing within N days (default 30), soonest first.
```

## Only reads (2)

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

### `grant_search`

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

Description, as the server wrote it:

```untrusted-server-text
FREE. Open and forecasted US federal grants matching a keyword (e.g. 'broadband', 'small business', 'opioid') — top 3.
```

### `grant_search_full`

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

Description, as the server wrote it:

```untrusted-server-text
PRO. Up to 100 grants for several keywords with agency code and eligibility filters (e.g. eligibilities '12' nonprofits, '23' small business, '25' others).
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `us-federal-grants`:

```json
{
  "permissions": {
    "allow": [
      "mcp__us-federal-grants__grant_search",
      "mcp__us-federal-grants__grant_search_full"
    ],
    "ask": [
      "mcp__us-federal-grants__closing_soon"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-29T22:29:32.757Z, unchanged since 2026-10-29T22:29:32.757Z. 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 | `1` |
| Protocol version | `2025-06-18` |
| 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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://us-federal-grants-mcp.donniertf.workers.dev/mcp: tools/list returned 3 tools to an anonymous client, including closing_soon (write)
