## Tools

15 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `list_tenants` — List tenants on this Handset account. A tenant is one of your customers' businesses — it owns numbers, conversations, and opt-out lists.
- `create_tenant` — Create a tenant (one customer business). Returns the tenant with its tnt_… id.
- `search_numbers` — Search purchasable phone numbers by area code. Free and instant in test mode.
- `buy_number` — BILLABLE in live mode (monthly rental): purchase a phone number for a tenant. In test mode numbers are free and simulated. Confirm with the user before buying o
- `list_numbers` — List the account's phone numbers, optionally for one tenant.
- `send_message` — OUTWARD-FACING: send an SMS (or MMS with media_urls) from a tenant number. In live mode this texts a real person and bills per segment — confirm with the user f
- `list_conversations` — List message threads, newest activity first.
- `get_thread` — Read one conversation's messages, oldest first.
- `make_call` — OUTWARD-FACING: place a click-to-call — dials connect_to (the agent's phone) first, then to (the customer), and bridges them; both see the tenant number. Live m
- `get_call` — Retrieve a call: status, duration, AI summary (arrives ~15s after a transcribed call ends), and the event timeline (gathers, keypresses, streams).
- `list_calls` — List calls with status and duration, newest first.
- `get_transcript` — Read a call's transcript so far — callable mid-call for live transcription.
- `start_transcription` — Turn on live transcription for an in-progress call (either direction). Idempotent. Billed per transcribed minute; an AI summary generates after hangup.
- `list_voicemails` — List voicemails with transcripts and time-limited audio URLs.
- `get_usage` — This month's usage by kind (segments, minutes, transcription, streams…). Test-mode usage is metered but never billed.

## Install

**Verdict: review** — Installable, but 1 thing to check first: No publisher has proved control of this listing; it is indexed, not vouched for.
**Cautions** (coverage gaps and advisories — never blocking)
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"mcp\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@handset/mcp\"\n      ]\n    }\n  }\n}"
```

## Blast radius

Contained to moderate — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs on your machine; read-only tool surface.
- Floor 13, ceiling 31 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
