## 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`: 10 of 10 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 2,326 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`: 10 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: 10, about 2,326 tokens to load them all

### Tool changes

- 2026-10-05 `check_compliance` changed (inputSchema)
- 2026-10-05 `send_transactional_confirmation` changed (description)
  - before: Idempotent transactional messages: OTPs, booking confirmations, payment receipts, cancellation notices. Falls back across configured channels; an unconfigured channel fails honestly rather than reporting a delivery that did not happen. [$0.02/per_call] [async→get_outcome] [Not available on this deployment: SMS.]
  - after: Idempotent transactional messages: OTPs, booking confirmations, payment receipts, cancellation notices. Falls back across configured channels; an unconfigured channel fails honestly rather than reporting a delivery that did not happen. [$0.02/per_call, not charged while no payment rail is on] [async→get_outcome] [Not available on this deployment: SMS.]
- 2026-10-05 `send_message` changed (description, inputSchema)
  - before: Send a message on behalf of an agent's user or an SMB across WhatsApp (free during launch), SMS, email, or voice, sent immediately with no scheduling. Every send routes through a non-bypassable gate (TCPA, GDPR, CASL, PDPL across 26 jurisdictions): marketing without recorded consent is rejected at runtime with a structured compliance_violation receipt. [from $0.02/call, variable] [async→get_outcome] [Not available on this deployment: SMS, Voice.]
  - after: Send a message on behalf of an agent's user or an SMB across WhatsApp (free during launch), SMS, email, or voice, sent immediately, no scheduling. Every send passes a non-bypassable gate: TCPA, GDPR, CASL where modeled, else the service's own opt-in default (the Gulf included). Marketing on SMS, voice, WhatsApp and non-US email without recorded opt-in is rejected (compliance_violation receipt). US marketing email follows CAN-SPAM opt-out rules. [from $0.02/call, variable, not charged while no payment rail is on] [async→get_outcome] [Not available on this deployment: SMS, Voice.]
- 2026-10-03 `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]
- 2026-10-03 `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]

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]
- 2026-10-01 `send_transactional_confirmation` changed (description)
  - before: Idempotent transactional messages: OTPs, booking confirmations, payment receipts, cancellation notices. Falls back across configured channels; an unconfigured channel fails honestly rather than reporting a delivery that did not happen. [$0.02/per_call] [async→get_outcome]

- 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]
  - after: Find real businesses near a place, sorted by distance (nearest of those examined; dense areas are narrowed, see result.search).

[free, no key]
- 2026-09-27 `send_message` changed (description)
  - before: Send a message on behalf of an agent's user or an SMB via WhatsApp or email — both live. SMS and voice are advertised but NOT wired on this deployment: they always fail honestly (channel_not_configured), uncharged. Sent immediately, no scheduling. Every send passes a non-bypassable gate (TCPA, GDPR, CASL, PDPL, 26 jurisdictions): marketing without recorded consent gets a structured compliance_violation receipt. [from $0.02/call, variable] [async→get_outcome]

## Packages

_none_

## Tools (10)

- `check_compliance`: Free, instant pre-flight for the compliance gate: runs the SAME TCPA/GDPR/CASL/CAN-SPAM/10DLC checks as send_message and call_business, in preview mode -- nothing is sent, nothing changes. Tells you whether a send would be permitted before you pay, and if not, names the exact rule and how to fix it. De-risks a paid send the way check_booking_link de-risks a paid booking. [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_conversation`: Read a two-way conversation thread you started: its state, every message exchanged, and how many replies the business has sent. [free, requires key]
- `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]
- `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]
- `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]
- `send_message`: Send a message on behalf of an agent's user or an SMB across WhatsApp (free during launch), SMS, email, or voice, sent immediately, no scheduling. Every send passes a non-bypassable gate: TCPA, GDPR, CASL where modeled, else the service's own opt-in default (the Gulf included). Marketing on SMS, voice, WhatsApp and non-US email without recorded opt-in is rejected (compliance_violation receipt). US marketing email follows CAN-SPAM opt-out rules. [from $0.02/call, variable, not charged while no payment rail is on] [async→get_outcome] [Not available on this deployment: SMS, Voice.]
