Make a key

MCP server · version 1.1.0

Connect your AI to Groundbreak

Ask Claude, ChatGPT, Cursor or any MCP client about the public record in 8 markets: permits, deeds, loans and liens, the projects behind them and the companies on them. Look up who owns a property and who is behind the LLC, and work your deals in the CRM. 22 tools, one account.

Serverhttps://mcp.groundbreak.city/mcp
Point your agent athttps://docs.groundbreak.city/mcp.md

Auth: the Claude app, ChatGPT and other clients that sign in with OAuth need only the server address. Others send Authorization: Bearer <your key>. Make a key, free with any account.

Connect

The Claude app and ChatGPT sign in: paste the address and approve. For the others, make a key on your API page in Groundbreak Pro, one per client; the setup there has it filled in. The CRM's Connect AI page holds the same keys.

  1. Run this in a terminal. Every Claude Code session gets Groundbreak. Or leave out the header and run /mcp in Claude Code to sign in instead.
Terminal
claude mcp add --transport http groundbreak https://mcp.groundbreak.city/mcp \
  --header "Authorization: Bearer <your key>"

Requests and responses

Every request is an HTTP POST of one JSON-RPC 2.0 message, or a batch of them, to https://mcp.groundbreak.city/mcp with your key as a Bearer token. Each call below is a curl you can paste, with the answer it gets. Real responses from the public record, captured 2026-10-28, with lists cut to two items. The tools that change a workspace or spend credits show the shape they return, with a made-up person.

initialize

The first call a client makes. The answer names the server, the protocol version and, in instructions, the workspace, the plan, the limits and the credits left.

The database (search_records, search_projects, get_project, search_companies) holds permits, deeds, loans, starts, zoning cases and liens in Austin, Atlanta, Miami, Nashville, Tampa Bay, Charlotte, Dallas-Fort Worth, Toronto, the projects they belong to and the companies on them; anything filed in the last 90 days names its parties only on Pro, older records come back whole. The CRM: any Florida property, and outside Florida the counties Groundbreak reads (Travis, Dallas, Tarrant, Fulton, DeKalb, Davidson, Mecklenburg). Start from a property: lookup_property (address with city, folio or owner name), then add_property to save it; for a Florida property the owner's Sunbiz filing is read and the people behind an LLC become contacts (Sunbiz is Florida only). find_phones skip traces them and spends credits; ask the user before calling it. get_property and groundbreak_records return the public record: appraiser sales, clerk deeds, mortgages, liens, lis pendens and permits. Deals: list_deals, get_deal, create_deal, move_deal, add_note, create_task. Every result carries app URLs; link them. Never invent a phone or an owner. Numbers marked DNC must not be cold called. A result too long to send comes back with its longest lists cut and a trimmed note: narrow the ask for the rest. Full docs: https://docs.groundbreak.city/mcp.md. Workspace: Jordan's team. Plan: Pro. Limits: 60 API calls a minute and 2,000 API calls a day. Skip-trace credits left: 100."

Tools

Every result carries app links. Tools that change your CRM or spend credits say so in their description, and a good client asks you first. Open an example under each tool for its request body and the object that comes back in result.structuredContent.

The database

Permits, deeds, loans, notices of commencement, zoning cases and liens in every market, the projects they belong to and the companies on them. Parties on anything filed in the last 90 days come back with Pro; older records come back whole on any account.

search_records

Reads

Search Groundbreak's public-record filings in one market: building permits, deeds, loans, notices of commencement (starts), zoning and site plan cases, liens. Returns up to 25 rows, newest or biggest first, with the true count, the source record and an app link. Parties and phones on filings from the last 90 days come back on Pro; older filings come back whole for everyone.

Properties and owners

Any Florida property, and the county rolls Groundbreak reads outside Florida. Find the owner, the people behind an LLC (Florida, from Sunbiz), their phones, and the public record on the parcel.

lookup_property

Reads

Look up a property by street address, parcel id or folio, or every parcel an owner name holds: any Florida property on the statewide tax roll, and outside Florida any parcel in Travis, Dallas, Tarrant, Fulton, DeKalb, Davidson and Mecklenburg counties on the county rolls Groundbreak reads. Returns the owner, mailing address, use, size, value and last sale. Writes nothing; add_property saves one to the workspace.

Plans and limits

Pro returns the parties on filings from the last 90 days. Without Pro those come back withheld, and older filings come back whole.

PlanTool calls a minuteTool calls a day
Pro602,000
Without Pro20100

Limits count tool calls per person, across all of that person's keys. Connecting and listing tools are free. Daily limits reset at midnight UTC. Your calls today are on your API page. Need more a day? Ask for a higher limit there, or email max@groundbreak.city.

  • find_phones spends 1 credit for each person it finds a phone or email for. Misses are free, and anyone traced in the last 30 days is free again.
  • Pro ($27 a month) adds 50 credits to your workspace each month. A pack adds 200 for $27 and they keep.
  • Every other tool is free. Sunbiz people, phones on permits and owners of record never cost a credit.

Errors

WhatWhat it looks likeWhat to do
Not signed in, or a wrong, revoked or expired keyHTTP 401 with JSON-RPC error -32001 and a WWW-Authenticate headerA client that signs in starts the sign-in from that header; an expired sign-in refreshes on its own. Otherwise make a key at https://pro.groundbreak.city/connect and check the client sends it.
Past the limitA tool result with isError and "past your limit of ..."Wait for the window to reset: a minute, or midnight UTC. For a higher daily limit, ask at https://pro.groundbreak.city/connect or email max@groundbreak.city.
A read key asked to writeA tool result with isError and "This key reads only"Use a key with full access for that client.
Arguments the tool does not takeA tool result with isError and "Invalid arguments: ..."The message names the field. The tool list carries each input schema.
A refusal meant for youA result with an error field: an id from another workspace, no credits leftRead it to the person: it says what to do.
A failure on our sideA tool result with isError and "That tool failed on our side"We are told when this happens. Try again in a moment.

Keys and safety

  • A key, or an app you signed in to, acts as you in the workspace you picked. It reads everything you can.
  • With full access it also logs notes, makes and moves deals and spends credits in your name. Read only sees only the tools that read.
  • Make one key per client, so you can revoke one without the others. Revoking a key or disconnecting an app on your API page stops it at once.
  • A key in a URL lives in that client's settings. Treat the URL like a password, and prefer signing in where the client can.

Protocol

  • JSON-RPC 2.0 over HTTP POST, Streamable HTTP. Methods: initialize, ping, tools/list, tools/call. Batches work.
  • Answers are plain JSON, never an event stream. No sessions: every request stands alone. GET answers 405.
  • Protocol versions: 2025-11-25, 2025-06-18, 2025-03-26, 2024-11-05.
  • A result longer than 60,000 characters comes back with its longest lists cut and a trimmed note.
  • Tools carry readOnlyHint. On connect the server tells the client the workspace, the plan, the limits and the credits left.
  • OAuth 2.1: a request without a token gets a 401 whose WWW-Authenticate names the resource metadata; the server metadata lists the endpoints. Dynamic client registration, PKCE (S256 only), scopes mcp:full and mcp:read. Access tokens last 60 minutes; refresh tokens 90 days, replaced on every use.
