Field24 MCP server

Field24 MCP server

Connect your AI assistant to Field24. Attach a set of plans, ask for an estimate, and Field24 measures the takeoff, prices it from your own rates and local store prices, and builds a proposal, all in your Field24 account. Your assistant starts the work, checks on it and walks you through the results.

Open in ChatGPT

Using ChatGPT? Install the Field24 plugin from the ChatGPT directory instead of adding the server by hand: the plugin ships the estimating skills that tell ChatGPT how to run a takeoff, review it and price it. A bare MCP connection gets the tools without the playbook.

Quickstart

  1. Connect your assistant to https://field24.ai/mcp (steps for each app below).
  2. Sign in when Field24's page opens: enter your phone number and the code we text you. New to Field24? Your account is created on the spot.
  3. Attach your plans and ask. Start with one of these:
    • "Create an estimate based on this set of plans"
    • "Do a takeoff for this project"
    • "Price my takeoff and build a proposal I can send"

A takeoff takes 15 to 30 minutes. You don't have to wait in the chat: your assistant checks back and tells you when it's done.

Cursor

Add Field24 to ~/.cursor/mcp.json, then sign in when Cursor asks:

{
  "mcpServers": {
    "field24": { "url": "https://field24.ai/mcp" }
  }
}

VS Code

Add Field24 to .vscode/mcp.json, then start the server and sign in:

{
  "servers": {
    "field24": { "type": "http", "url": "https://field24.ai/mcp" }
  }
}

Codex

codex mcp add field24 --url https://field24.ai/mcp
codex mcp login field24

Other apps

Any app that supports remote MCP servers with sign-in works: add https://field24.ai/mcp as a server and sign in with your Field24 account when it asks.

What it can do

  • Create a project for each job and hold its plans, drawings and photos. See Files.
  • Measure a full quantity takeoff from the plans, have Field24's reviewer check it, and fix what the review finds. See the Estimating flow.
  • Price the takeoff from your price book and local store prices, then review the pricing.
  • Build a branded, e-signable PDF proposal.
  • Read and update your price book: your labor and material rates.

It works only on your own Field24 account, the same one you use at https://field24.ai/app. Starting a takeoff, pricing or a proposal needs a Field24 free trial or subscription; projects, files and your price book work without one.
