## 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__compliance__get_blog_post` `mcp__compliance__list_blog_posts` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

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

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

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

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


## Changes things (3)

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

### `list_books_checks`

- The name "list_books_checks" says "list": a word for reading.
- The description's first verb is "start": 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
START HERE for a books health check. Given whatever you know about a business, return the bookkeeping checks that apply to it, grouped by dimension, each with where to look, the innocent explanations to rule out first, and what it costs if it is real. Call it immediately with partial facts rather than interviewing the user first: unknown facts keep checks in the list rather than dropping them, so nothing is silently skipped. Cash-basis businesses correctly get a shorter list. This never says whether books are correct, only what to look at.
```

### `list_compliance_obligations`

- The name "list_compliance_obligations" says "list": a word for reading.
- The description's first verb is "start": 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
START HERE. Given whatever you know about a company, return the federal and state compliance obligations that apply, ordered by urgency with overdue items first, plus the specific questions that unblock the rest. Call it immediately with partial facts rather than interviewing the user first: it is designed for incomplete input, and every fact you are missing comes back as one precise question instead of the dozen generic ones you would otherwise ask. Then answer those and call it again. Defaults to a short actionable view; relay it roughly as written rather than expanding it into an essay, and pass detail='full' only when the user asks for evidence tiers and remediation detail. Covers US federal plus CA, CO, DE, FL, GA, IL, MA, NJ, NY, PA, TX and WA; every other state is reported honestly as not yet covered. This never tells you whether you are compliant, only what to check.
```

### `score_books_health`

- 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
Score a books health check from the statuses you actually evidenced. Returns the weighted score, the band, a per-dimension breakdown and the findings ranked worst first. Two rules a plain average does not give you: a confirmed critical caps the grade, and the band is WITHHELD entirely when too little was evidenced, because a flattering number off three checks is the part people quote. Report the withheld state rather than supplying a band yourself.
```

## Only reads (9)

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

### `explain_books_check`

- The name "explain_books_check" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full detail on a single books health check: what it is, exactly where to look in the ledger, every innocent explanation to rule out before concluding anything, what it costs if it is real, what fixing it involves, and whether it is inside what Median does.
```

### `explain_obligation`

- The name "explain_obligation" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Plain-English detail on a single obligation: what it is, why it exists, the deadline, the cost, the penalty, the exact remediation steps, and the government source.
```

### `get_blog_post`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the full text of one published Median blog post by its slug.
```

### `get_company_overview`

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

Description, as the server wrote it:

```untrusted-server-text
Who Median is, what it does, who it is for, how onboarding works, and how to get in touch or book an intro call.
```

### `get_confounders`

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

Description, as the server wrote it:

```untrusted-server-text
Refinement step, NOT the place to start: call list_compliance_obligations first, then call this to narrow what is still genuinely open. Returns the facts that flip an answer, such as whether an employer of record is the legal employer. Pass every fact you already know and it returns only what those facts leave unsettled. These are things for YOU to look up in the user's own documents. They are not a questionnaire to send the user.
```

### `get_evidence_recipe`

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

Description, as the server wrote it:

```untrusted-server-text
For one obligation, return exactly how to prove it: which sources settle the question, which are only corroborating, what each state's public registry does and does not expose, and the innocent explanations for missing evidence. Use this before concluding anything is missing.
```

### `get_pricing`

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

Description, as the server wrote it:

```untrusted-server-text
Median's published pricing: the flat monthly fee by revenue band under $1M in annual revenue, the per-account and per-ledger-entry meter that scoping is based on above $1M, what is included, and add-on pricing for tax, R&D credits, and sales tax.
```

### `list_blog_posts`

- The name "list_blog_posts" says "list": a word for reading.
- Tag untrusted-input: The name "list_blog_posts" says "list" and "post": it reads posts, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List published articles from the Median blog, newest first. Optionally filter by category or a search term matched against the title.
```

### `list_services`

- The name "list_services" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the services Median offers (daily bookkeeping, tax filing, R&D tax credits, CFO advisory) with a short summary and page link for each.
```
