Lawtte runs an MCP server at https://www.lawtte.ai/api/mcp. Connect Claude or any MCP client to it and that client can set your firm up for calling in two questions, place an outbound AI phone call, read what happened on one, read the transcript, list recent calls — including the ones your receptionist answered — and set up a full AI receptionist that activates on Lawtte’s site. You don’t need a Lawtte account to start; one is created when you sign in. You describe the objective in plain language — “call Maria and confirm she received the settlement paperwork” — and Lawtte dials from your firm’s own number, runs the call, and hands back a summary.

Connect Claude

Add the connector, sign in when Claude asks, and make your first call. No API key.

Connect any other client

Endpoint, OAuth discovery, and tool schemas for your own integration.

Inbound and outbound agents

Your receptionist answers calls; outbound agents make them. Which tools are which.

What the tools do

Calling setup, place_call and check_call, call results, and receptionist setup.

Guardrails

Calling hours, consent and AI disclosure, Do Not Call, and daily caps.

​
What a client gets

It also has seven tools for setting up a new receptionist from Claude. Nothing else is exposed — no resources, no prompts, and no access to your firm’s case data.

​
Which clients work

Any client that speaks MCP over streamable HTTP and can carry a bearer token.

Claude

As a custom connector, over OAuth. The path most firms take.

Grok Bot

By URL, over OAuth. Same server and tools as Claude.

Local / stdio clients

Via mcp-remote with an API key in a header file.

Your own software

Any MCP SDK. Register dynamically, no pre-issued credentials.

​
Requirements

Anyone can connect and set up a receptionist from Claude; a Lawtte account is created at sign-in. The call tools need a live Studio receptionist with a calling number. Set one up from Claude or at lawtte.ai/studio.
For the call tools:
  • A Studio account that is not paused, with a calling number assigned.
  • The Lawtte objective-calling agent enabled for your account.
  • A client that supports custom MCP servers.

​
How a call actually runs

1

The client asks

“Call Jane Doe at +1 212 555 0100 and find out whether she has the repair estimate yet.”
2

The user confirms

place_call is marked destructive, so a well-behaved client asks before dialing. check_call runs every check without placing a call.
3

Lawtte dials

The call comes from your Studio number. It opens with a fixed line introducing itself by name as a virtual assistant calling on behalf of your firm and saying the call is recorded, and the agent never gives legal advice.
4

The outcome comes back

When the call ends: whether the objective was met, a short summary, the suggested next step, and whether the person asked not to be called again.
These are real calls to real people, and they use your Studio minutes. Every call is subject to the limits, which are enforced server-side before dialing and fail closed.
