## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| 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__agentbookable__create_booking` `mcp__agentbookable__create_mandate` `mcp__agentbookable__create_mandate_for_draft` `mcp__agentbookable__find_businesses` `mcp__agentbookable__get_availability` `mcp__agentbookable__get_booking` `mcp__agentbookable__get_business` `mcp__agentbookable__list_services` `mcp__agentbookable__prepare_booking` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__agentbookable__prepare_booking` |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `create_booking`

- The name "create_booking" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).
- 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
Create a REAL appointment. CONSEQUENCEFUL: only after the user has explicitly chosen a slot and authorized the booking in their own words. Flow: (1) check the service's bookingRequirements and collect any required customer details (e.g. phone); (2) create a mandate via the create_mandate tool with the user's exact instruction; (3) call this tool with the mandateRef. The mandate is single-use and expires in 15 minutes. On SLOT_NO_LONGER_AVAILABLE offer the returned alternatives — never rebook unilaterally.
```

## Changes things (3)

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

### `create_mandate`

- The name "create_mandate" says "create": a word for a change.
- 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
Legacy: record the user's authorization WITHOUT a booking draft. Prefer the draft flow: prepare_booking → show proposal → user agrees → create_mandate_for_draft → create_booking with draftId. The draft flow binds consent to the exact appointment the user saw.
```

### `create_mandate_for_draft`

- The name "create_mandate_for_draft" says "create": a word for a change.
- 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
After the user explicitly agrees to the exact proposal in the draft (an affirmative reply such as 'yes, book it' — the user having already seen business, service, date and time), assert consent here to get a single-use mandate bound to that draft. consentObtained must be true; this assertion is audited. If anything consequential changes (different time, service or business), prepare a NEW draft and get fresh consent.
```

### `prepare_booking`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.customer.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Prepare a booking draft: the concrete proposal (business, service, time, customer) to show the user. Validates live availability and customer requirements — if requirements are missing you get MISSING_CUSTOMER_REQUIREMENT: ask the user for those details first, then call again. Show the returned draft to the user as the final proposal (business, service, duration, date/time), then obtain explicit affirmative consent. The draft expires after 30 minutes; consent binds to this exact proposal.
```

## Only reads (5)

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

### `find_businesses`

- The name "find_businesses" says "find": 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
Search the AgentBookable registry for businesses that accept AI bookings. Search by free text, category, city, service name or geo radius. ALWAYS start here — the results include capability flags and _links telling you the exact next endpoints.
```

### `get_availability`

- The name "get_availability" says "get": 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
Find LIVE availability for a service. Always call this immediately before create_booking — slots are temporary (~60s) and revalidated at booking. Pass an ISO-8601 window; use a slot id from the result when booking.
```

### `get_booking`

- The name "get_booking" says "get": 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
Retrieve a booking by its AgentBookable id (bb_bkg_*). Requires the mandateRef issued for that booking (from create_booking / create_mandate). Provider identity is never returned.
```

### `get_business`

- The name "get_business" says "get": 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
Get one business's record by id (ab_bus_*) or slug. Includes capabilities (availability/booking/reschedule/cancellation/payment) — NEVER promise an action whose flag is false — plus _links to the service list, availability endpoint and booking flow, and per-service bookingRequirements (e.g. whether customer phone is required).
```

### `list_services`

- The name "list_services" says "list": 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
List the services a business has opened to AI booking. Each service has a durationMinutes and bookingRequirements telling you what customer details to collect (name/email/phone) BEFORE booking.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__agentbookable__find_businesses",
      "mcp__agentbookable__get_business",
      "mcp__agentbookable__list_services",
      "mcp__agentbookable__get_availability",
      "mcp__agentbookable__get_booking"
    ],
    "ask": [
      "mcp__agentbookable__prepare_booking",
      "mcp__agentbookable__create_mandate_for_draft",
      "mcp__agentbookable__create_mandate"
    ],
    "deny": [
      "mcp__agentbookable__create_booking"
    ]
  }
}
```

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

- `mcp__agentbookable__find_businesses`: untrusted-input
- `mcp__agentbookable__get_business`: untrusted-input
- `mcp__agentbookable__list_services`: untrusted-input
- `mcp__agentbookable__get_availability`: untrusted-input

## Remote posture

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |

- **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 4 tools that change things (1 destructive, 3 write). Whether a call also works without credentials was not tested: tools are never called.

https://agentbookable.com/mcp: tools/list returned 9 tools to an anonymous client, including create_booking (destructive), prepare_booking (write), create_mandate_for_draft (write), create_mandate (write)
