## 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__jagent__check_resume` `mcp__jagent__compare_versions` `mcp__jagent__grade_essay` `mcp__jagent__grade_with_rubric` `mcp__jagent__judge_choice` `mcp__jagent__judge_score` `mcp__jagent__judge_yes_no` |
| 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_resume`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Score a resume, optionally against a job posting: a 0-100 match score, the posting's keywords found and missing (matched literally, as an ATS search would), ATS format checks, the level fit, and the probability a recruiter would move it to interview.
```

### `grade_essay`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Grade one essay against a built-in rubric. kind "essay": six criteria and a letter grade, for class essays at middle school, high school or college level. kind "common-app": a Common App personal statement (pass the prompt number, 1-7). kind "sat": an SAT School Day essay, Reading/Analysis/Writing each 1-4 (pass the source passage to check quotations).
```

### `grade_with_rubric`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Grade one or more submissions (up to 30, in parallel) against a rubric you supply: each criterion scored on a 3- to 6-point scale, summed per submission. Each submission is graded in its own call, so its score never depends on the others.
```

### `judge_choice`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Pick the option that best fits a text, with a probability for every option and a confidence. Options map an id to a description of when it applies.
```

### `judge_score`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Place a text on an ordered scale you define (lowest level first) and get the nearest level, the exact position and a probability for each level.
```

### `judge_yes_no`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Ask any yes/no question about a text and get the probability that the answer is yes. Use for checks and gates, e.g. 'Does this reply answer the customer's question?'.
```

## Only reads (1)

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

### `compare_versions`

- The name "compare_versions" says "compare": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Which of two versions is stronger for a stated purpose. Asked twice with the order swapped and averaged, because the model favors the second option on close calls; if the two orders disagree the result is a tie.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__jagent__compare_versions"
    ],
    "ask": [
      "mcp__jagent__check_resume",
      "mcp__jagent__grade_essay",
      "mcp__jagent__grade_with_rubric",
      "mcp__jagent__judge_yes_no",
      "mcp__jagent__judge_choice",
      "mcp__jagent__judge_score"
    ],
    "deny": []
  }
}
```

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

- `mcp__jagent__check_resume`: untrusted-input
- `mcp__jagent__grade_essay`: untrusted-input
- `mcp__jagent__grade_with_rubric`: untrusted-input
- `mcp__jagent__judge_yes_no`: untrusted-input
- `mcp__jagent__judge_choice`: untrusted-input
- `mcp__jagent__judge_score`: untrusted-input
- `mcp__jagent__compare_versions`: untrusted-input

- **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://jev-agent.com/api/mcp: tools/list returned 7 tools to an anonymous client, including check_resume (write), grade_essay (write), grade_with_rubric (write), judge_yes_no (write), judge_choice (write) and 1 more
