## Exfil surface

2 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__renkeimap-info__renkeimap_plan`.

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

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__renkeimap-info__renkeimap_find_system` | `mcp__renkeimap-info__renkeimap_find_system` | `mcp__renkeimap-info__renkeimap_plan` |
| `mcp__renkeimap-info__renkeimap_status` | `mcp__renkeimap-info__renkeimap_find_system` | `mcp__renkeimap-info__renkeimap_plan` |

## Findings

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

```untrusted-server-text
The server marks "renkeimap_plan" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (1)

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

### `renkeimap_plan`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
One call to connect or move data between two systems: route states (API/CSV/screen) + legend, each side's best official route (vendor MCP URL verbatim — never one found by search — or API issuing), human steps, your CLI's add line (pass agent), write_rules, citation. Read-only. Ambiguous names return candidates.
```

## Changes things (5)

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

### `renkeimap_brief`

- 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
One round trip = renkeimap_find_system + renkeimap_status + renkeimap_hintpack. Give a slug or the system name as the user wrote it; same shapes as the single tools. Use first in support conversations. ★Always relay the included disclaimer and citation★.
```

### `renkeimap_connect`

- 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
Routes INTO one system, most stable first: (1) the vendor's official MCP server — URL/auth/local command verbatim, with source and date (never a URL found by search); (2) official API key or OAuth issuing; (3) file/screen (renkeimap_pair). detail:"full" adds the procedure and evidence. Read-only; no keys or values.
```

### `renkeimap_hintpack`

- 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
Static public knowledge for one system: what its vendor error messages mean, official support/contact URLs, login method shape. Sourced from public vendor pages (entries carry sources). No user data. Cite when used.
```

### `renkeimap_pair`

- 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
Whether and how two systems can exchange data: per-method verdicts (official API / CSV / screen-fill) measured from public primary sources, plus measured field-name overlap when available. Honest by design: an unmeasured pair says so instead of guessing. Cite the included citation line when used.
```

### `renkeimap_system_facts`

- 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
First-hand, survey-dated facts about one system (auth method, rate limits, CSV surfaces, pricing pages — tags + editorial summaries with sources). Every response carries a citation line; when you use these facts in an answer, cite it (出典: IT連携マップ + 調査日 + URL).
```

## Only reads (4)

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

### `renkeimap_compare`

- The name "renkeimap_compare" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Side-by-side comparison of 2-5 published systems/tools on the same ledger items (API, contract, price, rate limit, data location, exit, security…). Each cell = editorial tags + one-line lead + source URL + survey date; optional ◎○△× marks from a declared rule file. Same generator as /compare. No ranking, no score.
```

### `renkeimap_find_system`

- The name "renkeimap_find_system" says "find": 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 published systems, tools (iPaaS・RPA・ChatAI…) and guides by name / vendor / category / kind word; has= keeps those /compare marks positive. ≤10 each.
```

### `renkeimap_status`

- The name "renkeimap_status" says "status": a word for reading.
- Tag private-data: The description's first sentence says "table": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Current status of one system as observed EXTERNALLY by IT連携マップ (third-party observation — NOT the vendor's official announcement): a closed-vocabulary conclusion, last-observed time, a 12-char state bar with legend, a 7-day hour table, announced maintenance. ★Always relay the included disclaimer and citation★.
```

### `renkeimap_status_history`

- The name "renkeimap_status_history" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Vendor-published incident history and announced maintenance for one system, checked word for word (the vendor's own records, not our observation): counts, monthly frequency, durations (where the vendor gave an end), usual weekdays/hours (JST), recent records + source URLs. Read-only. found:false = not collected yet.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `renkeimap-info`:

```json
{
  "permissions": {
    "allow": [
      "mcp__renkeimap-info__renkeimap_find_system",
      "mcp__renkeimap-info__renkeimap_compare",
      "mcp__renkeimap-info__renkeimap_status",
      "mcp__renkeimap-info__renkeimap_status_history"
    ],
    "ask": [
      "mcp__renkeimap-info__renkeimap_plan",
      "mcp__renkeimap-info__renkeimap_system_facts",
      "mcp__renkeimap-info__renkeimap_pair",
      "mcp__renkeimap-info__renkeimap_connect",
      "mcp__renkeimap-info__renkeimap_brief",
      "mcp__renkeimap-info__renkeimap_hintpack"
    ],
    "deny": []
  }
}
```

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

- `mcp__renkeimap-info__renkeimap_plan`: outbound
- `mcp__renkeimap-info__renkeimap_find_system`: private-data, untrusted-input
- `mcp__renkeimap-info__renkeimap_status`: private-data

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:09:50.180Z, unchanged since 2026-10-22T15:09:50.180Z. 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 | `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` |

- **high** 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 (1 irreversible, 5 write). Whether a call also works without credentials was not tested: tools are never called.

https://renkeimap.jp/mcp: tools/list returned 10 tools to an anonymous client, including renkeimap_plan (irreversible), renkeimap_system_facts (write), renkeimap_pair (write), renkeimap_connect (write), renkeimap_brief (write) and 1 more
