## Exfil surface

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

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

| Private data | Untrusted input | Outbound |

## Findings

- **info** Long descriptions in `submit_listing` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 2,274 characters long, over the 2,000 this check looks for.

description ends: "...ion returns 400; duplicate/claim responses return 409. Read tools remain keyless."
```


## Can't be undone (1)

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

### `send_lead`

- The name "send_lead" says "send": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "send_lead" says "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Send a buyer-intent enquiry (lead) to a tool or a whole category on Tick Mark Books. Keyless. Requires consent:true, a real name, a permanent (non-disposable) email, a message of at least 20 chars, and a target (listingSlug OR categorySlug). Returns { ok, delivered }. Idempotent by (email, target) within 7 days. Nothing here changes a listing's rank, tier or copy.
```

## Changes things (3)

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

### `my_listings`

- 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
What the Tick Mark Books owner dashboard shows about the listings an account owns: each one's status (`status.kind`: review with the expected date, accepted with `liveOn` and `paid` ('express' | 'featured' | null: the paid way that releases it, Featured including VIP listing), live, refused with the reason, or archived), the listing as it shows, 30 days of real numbers with the 30 before, where AI answers named the product or cited its page, and what it can buy here at this site's prices. Only for the account itself: send its session Cookie header, or its agent key with "Read your listings" as Authorization: Bearer. Same answer as GET https://tickmarkbooks.com/api/owner/listings. Read-only: corrections go through the dashboard's request form.
```

### `submit_listing`

- The name "submit_listing" says "submit": a word for a change.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Submit a tool to Tick Mark Books: the url alone; we write its name and description from its own pages. Requires an existing signed-in account with verified email; send its session Cookie header on the MCP request, or an agent key the account made at https://tickmarkbooks.com/dashboard/agents as Authorization: Bearer. Identity and email come only from that session or key. Sign in or explicitly create an account at https://tickmarkbooks.com/login?next=%2Fsubmit and verify its email before retrying. This tool creates no account and sends no verification email. Returns {httpStatus:201, id, slug, status:'Draft'}; research + the quality gate decide publication. Your own (url, session email) replay within 24h returns httpStatus:200. The fit check starts at once and usually answers within a minute: poll GET https://tickmarkbooks.com/api/submissions/{id} and wait the Retry-After seconds it sends while fit is "checking". fit then reads "accepted" (it goes live, and the account is mailed), "rejected" (mailed with the reason) or "undecided" (a person looks within 2 days). No session: {httpStatus:401, error:'sign_in_required', message, loginUrl}. Unverified session: {httpStatus:403, error:'email_unverified', message, email, remediation}. The owner must prove the site before anything is listed: the account's address, or an address it proved with a code, must be on the submitted website's domain. Otherwise the answer is the pending state {httpStatus:403, error:'domain_unverified', status:'awaiting_owner_proof', listed:false, message, domain, proveWith, ownerUrl, ownerStep, remediation}: nothing is listed or queued. proveWith names who can receive the 6-digit code (any address at the domain; for a GitHub or other shared-host project, its listed addresses or a one-line file). Submitting for someone else? Give the owner ownerUrl (the submit page with the site filled in): they enter the code there and the listing goes in once proven. With a mailbox at the domain yourself: POST /api/domain-proof/start {url, email}, POST /api/domain-proof/verify {proofId, code}, then submit again. Personal mailboxes (gmail, outlook…) never prove a domain. No refusal creates a listing. Validation returns 400; duplicate/claim responses return 409. Read tools remain keyless.
```

### `subscribe_newsletter`

- The name "subscribe_newsletter" says "subscribe": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Subscribe an email to the Tick Mark Books digest of new and freshly re-verified tools. Provide an email; returns { ok }. The address is on the list at once and gets one welcome mail. Every mail carries a one-click unsubscribe.
```

## Only reads (5)

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

### `compare_listings`

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

Description, as the server wrote it:

```untrusted-server-text
Two tools side by side, as markdown: taglines, pricing, API availability, tags — the researched compare facts, honest about unknowns.
```

### `get_best_of`

- The name "get_best_of" says "get": a word for reading.
- Tag private-data: The description's first sentence says "doc": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
The Published tools in one category, in the order its category page prints (ranked by what we can confirm: a public price, an API and docs, independent sources, stated limits), as a markdown answer sheet. Payment never moves a row.
```

### `get_listing`

- The name "get_listing" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
One tool in full, as answer-first markdown: the summary, then every question on the sheet with its answer, the vendor's own words for it and the URL that proves it. Identical to /{slug}.md and to the HTML page.
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
Tick Mark Books's categories with their live listing counts, 0 for one with none yet.
```

### `search_listings`

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

Description, as the server wrote it:

```untrusted-server-text
Full-text search over Tick Mark Books's Published tools. Returns compact records (name, slug, tagline, url). Fetch depth with get_listing.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__tickmarkbooks__search_listings",
      "mcp__tickmarkbooks__get_listing",
      "mcp__tickmarkbooks__list_categories",

      "mcp__tickmarkbooks__send_lead",
      "mcp__tickmarkbooks__my_listings",
      "mcp__tickmarkbooks__subscribe_newsletter"
    ],
    "deny": []
  }
}
```

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

- `mcp__tickmarkbooks__get_listing`: untrusted-input
- `mcp__tickmarkbooks__get_best_of`: private-data
- `mcp__tickmarkbooks__submit_listing`: outbound
- `mcp__tickmarkbooks__send_lead`: untrusted-input, outbound
