What you can do with Farmbrite in Claude and ChatGPT

For farmers and ranchers who track livestock, crops and sales in Farmbrite.

Review animals with their measurements and treatments

The AI lists animals by status and opens one with its location and custom fields. It reads weight, temperature and condition score records and treatment records.

Check grazing status of fields and pastures

The AI reads, per field or pasture, the animals present, days rested, rest days required and the last grazing date, so you see which fields are ready.

Check inventory and where it is stored

The AI lists inventory items with quantity remaining, value and low-stock alert level, and reads the warehouse and bin where one item is stored.

Log a feeding, measurement, treatment or harvest

The AI records a feeding for an animal or group (it can draw the feed from inventory), a measurement, a treatment such as a vaccine or dewormer, or a harvest.

Changes data

Create or update farm tasks

The AI lists tasks with status, priority and due date, creates a task linked to an animal, field or crop, or changes a task and marks it done.

Changes data

Review, create or update sales orders

The AI lists sales orders with status and payment status, opens one with its line items, creates an order, or changes an order's status or payment status.

How do I connect Farmbrite?

Before you connect

The login page asks for your Farmbrite API key.

Find it in Farmbrite under your user profile → API Key (Farmbrite enables API access on request: see developers.farmbrite.com). The key acts with that user's permissions, so Farmbrite recommends a separate user for integrations. Your key is used only to call the Farmbrite API on your behalf; it is never shown to anyone.

Claude claude.ai · Desktop

  1. Open Customize → Connectors, then click + Add → Add custom connector.
  2. Enter the name Farmbrite and this URL, then click Add:
    https://farmbrite.usefulapi.io/mcp
  3. Claude opens the login page: enter your Farmbrite API key.
  4. In a chat, click + → Connectors and turn on Farmbrite.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

  1. Open Plugins, click +, then Add custom MCP server.
  2. Enter the name Farmbrite and this URL, choose OAuth as the authentication, confirm the warning and create it:
    https://farmbrite.usefulapi.io/mcp
  3. ChatGPT opens the login page: enter your Farmbrite API key.
  4. In Plugins, install Farmbrite, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http farmbrite https://farmbrite.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "farmbrite": {
      "url": "https://farmbrite.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "farmbrite": {
      "type": "http",
      "url": "https://farmbrite.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add farmbrite --url https://farmbrite.usefulapi.io/mcp
codex mcp login farmbrite

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://farmbrite.usefulapi.io/mcp

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Farmbrite API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Free$050 tool calls / month
Proper user$9/mo · $90/yr10,000 tool calls / month

Each paid plan covers this Farmbrite server only. Ask your AI to run farmbrite_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with farmbrite_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with farmbrite_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4

  • Usage status (free-tier meter)farmbrite_usage_status
    Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
  • Request a missing featurefarmbrite_request_feature
    Tell usefulapi that the user needs something the Farmbrite tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
  • Upgrade to Pro or Pro+farmbrite_upgrade
    Get a paid plan for Farmbrite (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
  • Cancel the Pro subscriptionfarmbrite_cancel_subscription
    Cancel the caller's Farmbrite Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run farmbrite_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Farmbrite in Claude or ChatGPT?

Review animals with their measurements and treatments. Check grazing status of fields and pastures. Check inventory and where it is stored. Log a feeding, measurement, treatment or harvest. Create or update farm tasks. Review, create or update sales orders. See what you can do for the details.

Is this an official Farmbrite product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Farmbrite. The server calls the Farmbrite API with your own Farmbrite access, so it sees only the data that your account can see.

Can I connect Farmbrite to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Farmbrite API key. See Before you connect for where to find it.

Do I put my Farmbrite key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Farmbrite API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Farmbrite credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Farmbrite API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Farmbrite.

Can the AI change my Farmbrite data?

Yes, if you approve it. 16 of the 44 Farmbrite tools can create or change data. The other 28 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Farmbrite server only. Cancel any time: your paid plan then runs to the end of the paid period. Run farmbrite_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run farmbrite_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run farmbrite_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Farmbrite tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with farmbrite_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.

Need a tool this server does not have, or a connection to another system? We build custom integrations and MCP servers.
