## Quality 84/100 (good)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 300000)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 9 of 9 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,979 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 7 tool changes in 30 days
- fail `stability.rug_pull`: 1 tools kept their name but changed most of their description in 30 days; review before trusting them

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 9, about 1,979 tokens to load them all
- tool set hash: 73491c6b795a4ba45767de957504a3c4

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-05 `schedule_appointment` changed (description)
  - before: Check availability, book, or cancel via Cal.com. Only completes when the SMB's imported booking link is bound to this deployment's ONE connected Cal.com account; otherwise fails honestly (booking_destination_unmapped) with no charge. No working booking path exists yet for non-Cal.com platforms (voice AI, web form) — those SMBs fail honestly instead of a fabricated confirmation. [from $0.15/call, variable] [async→get_outcome] [limited]
  - after: Check availability, book, or cancel via Cal.com. Only completes when the SMB's imported booking link is bound to this deployment's ONE connected Cal.com account; otherwise fails honestly (booking_destination_unmapped) with no charge. No working booking path exists yet for non-Cal.com platforms (voice AI, web form) — those SMBs fail honestly instead of a fabricated confirmation. [from $0.15/call, variable, not charged while no payment rail is on] [async→get_outcome] [limited]
- 2026-10-04 `import_booking_url` changed (description)
  - before: Turn a public booking URL into a callable smb_id for send_message and capture_lead. But schedule_appointment only completes on Cal.com bound to our one connected account — the other 11 always fail schedule_appointment honestly, uncharged. Detects 12 platforms (Cal.com, Calendly, Doctolib, Booksy, Fresha, OpenTable, Setmore, Square, Acuity, Schedulista, Squarespace, BookMyCity). Idempotent — calling twice returns the same smb_id. [free, requires key]

- 2026-10-04 `verify_business` changed (description)
  - before: Look up what we know about a business in our supply network: its contact channels, capabilities, and when the record was last verified. This is a DIRECTORY LOOKUP - it does not contact the business. [free, no key]
  - after: Look up what we know about a business in our supply network: contact channels, capabilities, last verification. A DIRECTORY LOOKUP - it does not contact the business. Supply-network ids only, not osm:... ids. [free, no key] [limited]
- 2026-10-04 `find_business` changed (description, inputSchema)
  - before: Find real businesses near a place, sorted by distance (nearest of those examined; dense areas are narrowed, see result.search). Data: OpenStreetMap (ODbL, (c) OpenStreetMap contributors, attributed per result); phone, website, hours only when mapped. Coverage varies; community-mapped, NOT verified by us; source=openstreetmap rows cannot be booked. Plus supply-network rows. If OSM is down: retriable 'temporarily unavailable', never invented rows. [free, no key]
  - after: Find real businesses near a place, sorted by distance (nearest of those examined; see result.search). Data: OpenStreetMap (ODbL, (c) OSM contributors); phone, website, hours only when mapped. Coverage varies; community-mapped, NOT verified by us; source=openstreetmap rows cannot be booked. Answers within about 5 s: status partial (search_in_progress) means repeat the call. If OSM is down: retriable 'temporarily unavailable', never invented rows. [free, no key] [beta]
- 2026-09-30 `find_business` changed (description, inputSchema) **meaning changed**
  - before: Given criteria (vertical, location, capability, price band, availability window), return ranked candidate businesses from our supply network. THE NETWORK IS SMALL AND STILL MOSTLY SAMPLE DATA: entries that are not real are named [DEMO] and flagged is_demo - check that field before acting on a result. [free, no key]

## Packages

_none_

## Tools (9)

- `check_booking_link`: Free, instant pre-flight check for a booking URL. Classifies which booking platform a URL belongs to and tells you whether import_booking_url will accept it, WITHOUT fetching the page or spending money. Returns the platform, the exact smb_id import_booking_url would assign, the channels the booking will route through, and the inferred country. Use it to de-risk a paid booking BEFORE calling import_booking_url + schedule_appointment. [free, no key]
- `find_business`: Find real businesses near a place, sorted by distance (nearest of those examined; see result.search). Data: OpenStreetMap (ODbL, (c) OSM contributors); phone, website, hours only when mapped. Coverage varies; community-mapped, NOT verified by us; source=openstreetmap rows cannot be booked. Answers within about 5 s: status partial (search_in_progress) means repeat the call. If OSM is down: retriable 'temporarily unavailable', never invented rows. [free, no key] [beta]
- `get_outcome`: Retrieve the final OutcomeReceipt for a completed operation. [free, no key]
- `get_status`: Query the current state of any in-flight async operation by operation_id. [free, no key]
- `import_booking_url`: Turn a public booking URL into a callable smb_id for send_message and capture_lead. But schedule_appointment only completes on Cal.com bound to our one connected account — the other 11 always fail schedule_appointment honestly, uncharged. Detects 12 platforms (Cal.com, Calendly, Doctolib, Booksy, Fresha, OpenTable, Setmore, Square, Acuity, Schedulista, Squarespace, BookMyCity). Idempotent — calling twice returns the same smb_id. [free, requires key] [limited]
- `preview_cost`: Return an expected cost estimate, latency estimate, and success-probability estimate for a proposed call before execution. Returns the exact price when it is fixed, and a min/max range when the cost depends on channel or outcome. It does not promise an accuracy percentage - check cost_range. [free, no key]
- `schedule_appointment`: Check availability, book, or cancel via Cal.com. Only completes when the SMB's imported booking link is bound to this deployment's ONE connected Cal.com account; otherwise fails honestly (booking_destination_unmapped) with no charge. No working booking path exists yet for non-Cal.com platforms (voice AI, web form) — those SMBs fail honestly instead of a fabricated confirmation. [from $0.15/call, variable, not charged while no payment rail is on] [async→get_outcome] [limited]
- `self_test`: Service health probe: runs 6 internal checks and reports how many passed. Confirms the server is up and responding - it does NOT probe each tool individually. Use to verify connectivity before production use. [free, no key]
- `verify_business`: Look up what we know about a business in our supply network: contact channels, capabilities, last verification. A DIRECTORY LOOKUP - it does not contact the business. Supply-network ids only, not osm:... ids. [free, no key] [limited]
