## Exfil surface

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

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

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__claspine__check_upgrade` | `mcp__claspine__get_recipe` | `mcp__claspine__upgrade_notes` |
| `mcp__claspine__get_guide` | `mcp__claspine__get_recipe` | `mcp__claspine__upgrade_notes` |
| `mcp__claspine__search_docs` | `mcp__claspine__get_recipe` | `mcp__claspine__upgrade_notes` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "what_runs_where" says "run": a word for a change.
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "get_recipe" says "get": a word for reading.
```

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

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

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

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

```untrusted-server-text

```

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

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

```


## Can't be undone (1)

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

### `upgrade_notes`

- 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
Every Claspine upgrade note after one version up to another, oldest first, with what changed, the checklist for product code and what to do before deploying. Read them all before changing the Claspine version.
```

## Changes things (7)

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

### `api_reference`

- 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
The published HTTP contract shared by Claspine Atlas and the self-hosted engine (paths under /api/v1). Without path: every operation. With path (and method): parameters, request body and responses with schemas resolved.
```

### `check_code`

- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Runs Claspine's Agent Shield rules on files or a unified diff: hardcoded or client-exposed secrets, SQL built from strings, unscoped tenant queries, secrets in logs, buffered uploads, imports of platform internals. Returns file, line, rule and the fix. Code is analysed in memory and not stored. A clean result is not proof of safety; Spring Boot builds also run ProductBoundaryTest.
```

### `check_config`

- 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
Checks application.yml / application.properties or the engine's environment variables: empty values that switch providers on, sandbox sign-in in STAGING/PRODUCTION, IP addresses as hosts, secrets written into settings, and misspelled setting names. Content is not stored.
```

### `explain_error`

- The name "explain_error" says "explain": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
What a Claspine error code means and how to fix it: HTTP status, the messages it is raised with, where, and the fix for common ones. Every Claspine error response carries its code.
```

### `get_recipe`

- The name "get_recipe" says "get": a word for reading.
- The description's first verb is "copy": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The description's first sentence says "copy" and "http": it reads web pages, which anyone can write.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Copy-ready HTTP calls for a common task on Claspine Atlas or the self-hosted engine, in curl, Node.js, Python, Go or Java, checked against Claspine's API on every build. Without task: the list.
```

### `java_api`

- 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
The public Java types of a Claspine capability (its api package) and of the foundation, with methods and record fields, from the current platform build. Without arguments: the capabilities.
```

### `what_runs_where`

- The name "what_runs_where" says "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Which Claspine capabilities exist on Claspine Atlas, the self-hosted engine (any language over HTTP) and self-hosted Spring Boot. Check this before planning any Claspine integration: they differ (for example, Claspine Atlas has no sign-in, permissions or push).
```

## Only reads (3)

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

### `check_upgrade`

- The description's first verb is "find": a word for reading.
- Tag private-data: The description's first sentence says "find" and "file": it reads files. The input names a file (input.files), and the tool reads: it reads files.

Description, as the server wrote it:

```untrusted-server-text
Finds the Claspine version in project files (pom.xml, build.gradle, package.json, docker-compose.yml) or takes it as given, and lists the checklist items of every upgrade note up to the target.
```

### `get_guide`

- The name "get_guide" says "get": 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
The full text of one Claspine guide: steps, code, settings, safety notes and troubleshooting.
```

### `search_docs`

- The name "search_docs" says "search": a word for reading.
- Tag private-data: The name "search_docs" says "search" and "doc": it reads documents. The description's first sentence says "search" and "table": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Search Claspine's guides, recipes, capability table and error fixes with a plain question or keywords. Returns the best matches first, with links; follow up with get_guide or get_recipe.
```
