Anlyon alternative

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

    Why it is in this group

    • The name "send_lead" says "send": a word for sending, and what is sent cannot be taken back.

    What it can reach

    • outboundThe name "send_lead" says "send": it sends or publishes something to other people.
    Description, as the server wrote it
    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.

    Why it is in this group

    • 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
    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.

      What this check looks for
    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

4 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 private-data tool breaks every one.

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write2
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out2
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
deny to break every path
{
  "permissions": {
    "deny": [
      "mcp__tickmarkbooks__get_best_of"
    ]
  }
}

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

    What this check looks for

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http tickmarkbooks https://tickmarkbooks.com/mcp
claude mcp add --transport http tickmarkbooks https://tickmarkbooks.com/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__tickmarkbooks__search_listings",
      "mcp__tickmarkbooks__get_listing",
      "mcp__tickmarkbooks__list_categories",
      "mcp__tickmarkbooks__compare_listings",
      "mcp__tickmarkbooks__get_best_of"
    ],
    "ask": [
      "mcp__tickmarkbooks__submit_listing",

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

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as tickmarkbooks. Review it before you use it.
