## Exfil surface

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

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

| Private data | Untrusted input | Outbound |

## Findings

- **info** The word "credentials" in `create_order` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...der with payment.url: POST it without a credential for a 402 card challenge (MPP, method s..."
```


## 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 AgentsIndex. 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 (4)

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

### `create_order`

- The name "create_order" says "create": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Turns a quote (from get_quote) into an order, payable for 24 hours. Same account as the quote: its session Cookie header, or its agent key as Authorization: Bearer (order scope). Returns the order with payment.url: POST it without a credential for a 402 card challenge (MPP, method stripe, a Stripe Shared Payment Token), then again with Authorization: Payment. Pass idempotency_key to make a retry return the same order. The price includes any VAT. Nothing is charged by this tool.
```

### `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 AgentsIndex 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 Express review), 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://agentsindex.ai/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.

Description, as the server wrote it:

```untrusted-server-text
Submit a tool to AgentsIndex: 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://agentsindex.ai/dashboard/agents as Authorization: Bearer. Identity and email come only from that session or key. Sign in or explicitly create an account at https://agentsindex.ai/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://agentsindex.ai/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}. Company gate: the account's address, or an address it proved with a code, must be on the submitted website's domain; otherwise {httpStatus:403, error:'domain_unverified', message, domain, remediation} — POST /api/domain-proof/start {url, email} mails a 6-digit code to an address at that domain, POST /api/domain-proof/verify {proofId, code} redeems it, 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
Single opt-in subscribe to the AgentsIndex digest of new and freshly re-verified tools. Provide an email; returns { ok }. Every issue carries a one-click unsubscribe.
```

## Only reads (7)

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.
```

### `get_quote`

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

Description, as the server wrote it:

```untrusted-server-text
A signed price for one offer (from list_offers) on one listing, valid for a short time, and whether the listing can have it now. Only the account that owns the listing gets one: send its session Cookie header, or its agent key as Authorization: Bearer, on the MCP request. Refusals say why and what to do (httpStatus 401 sign_in_required, 403 not_owner with the claim page, 409 not_accepted, already_live, already_bought, category_full). Nothing is reserved or charged.
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
AgentsIndex's taxonomy with live listing counts.
```

### `list_offers`

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

Description, as the server wrote it:

```untrusted-server-text
What a listing owner can buy on AgentsIndex, with prices in US cents (VAT included), each offer's term and what it needs. Keyless. Same answer as GET https://agentsindex.ai/api/agent/catalogue. Listing on AgentsIndex is free and never sold: submit_listing.
```

### `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 AgentsIndex'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 `agentsindex`:

```json
{
  "permissions": {
    "allow": [
      "mcp__agentsindex__search_listings",
      "mcp__agentsindex__get_listing",
      "mcp__agentsindex__list_categories",
      "mcp__agentsindex__compare_listings",
      "mcp__agentsindex__get_best_of",
      "mcp__agentsindex__list_offers",
      "mcp__agentsindex__get_quote"
    ],
    "ask": [
      "mcp__agentsindex__submit_listing",
      "mcp__agentsindex__send_lead",
      "mcp__agentsindex__create_order",
      "mcp__agentsindex__my_listings",
      "mcp__agentsindex__subscribe_newsletter"
    ],
    "deny": []
  }
}
```

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

- `mcp__agentsindex__get_listing`: untrusted-input
- `mcp__agentsindex__get_best_of`: private-data
- `mcp__agentsindex__submit_listing`: outbound
- `mcp__agentsindex__send_lead`: untrusted-input, outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:18:55.048Z, unchanged since 2026-10-22T14:18:55.048Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `5` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |

- **high** 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 5 tools that change things (1 irreversible, 4 write). Whether a call also works without credentials was not tested: tools are never called.

https://agentsindex.ai/mcp: tools/list returned 12 tools to an anonymous client, including send_lead (irreversible), submit_listing (write), create_order (write), my_listings (write), subscribe_newsletter (write)
