How does Mercateer work with OpenCode?

Mercateer runs a public MCP server. You add it to opencode.json as a remote server, and OpenCode can then call Mercateer tools to read calls and contacts, quote from your price book, and book appointments, from the terminal.

Is OpenCode free to use?

Yes. OpenCode itself is free and open source, and it works with 75+ LLMs, so you bring the model account you already have. On the Mercateer side, API and MCP access is included on the Crew and Fleet plans.

Global vs. project scope, which should I use?

Project scope (opencode.json in your repo root) is best when only one repo's tasks involve Mercateer. Global (~/.config/opencode/opencode.json) is best if you regularly jump between repos.

Which Mercateer plan do I need?

API and MCP access is included on the Crew and Fleet plans. You can start building free to set up your agent, then upgrade to connect OpenCode.

Are there rate limits?

Yes. API requests are rate-limited per caller (about 60 requests per minute per API key or connected agent). If you exceed the limit you get an RFC 9457 problem response with a Retry-After header, so the agent can back off and retry.

Can I give an agent read-only access?

Read-only scoping works through API keys, which each carry an explicit scope list, so you can issue a read-only key for lookups and a separate read-write key for agents that book jobs or update contacts. Note that the OAuth sign-in these agents use grants the agent the same full account access you have in the dashboard, so to keep an agent read-only you would connect it with a scoped API key rather than OAuth. Either way, actions that spend money or change live settings still pause for your confirmation.

What happens to my data?

Your calls, contacts, and pricing stay in your Mercateer organization. Agents act through scoped OAuth tokens or API keys, every request is logged, and actions that spend money or change live settings require your confirmation. Nothing is used to train a shared model.

What is OpenCode?

OpenCode is an open-source AI coding agent built by Anomaly: it runs in your terminal with a rich interface and works with 75+ LLMs. Add the Mercateer MCP server to its config and OpenCode can do front-office work too, pulling calls and contacts, quoting from your price book, and booking jobs without leaving the command line.

One-step setup

Fastest path: paste this into OpenCode and it connects Mercateer itself.

prompt

Fetch https://mercateer.com/prompt.md

Add the Mercateer MCP server

Merge the snippet below into opencode.json in your project root, or into ~/.config/opencode/opencode.json to make it available everywhere.

json

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "mercateer": {
      "type": "remote",
      "url": "https://api.mercateer.com/mcp",
      "enabled": true
    }
  }
}

Authorize over OAuth

Run `opencode mcp auth mercateer` in your terminal and finish the sign-in in your browser. There are no API keys to paste.

Confirm the connection

Run `opencode mcp list` to confirm the Mercateer server shows as connected, then try one of the example prompts below.

Try a prompt

Ask OpenCode to do real front-office work, like quoting a job or booking an appointment. It calls the right Mercateer tools and pauses for your approval on anything that spends money or changes a live setting.

Example prompts

You

Pull yesterday's missed calls and summarize what each caller wanted.

You

Quote a 50-gallon water heater install from my price book.

You

Book the Cedar Lane job for Thursday at 9am and confirm the slot is open.

You

Find the contact for (555) 123-4567 and show their last conversation.

You

Which calls this week asked for a service we don't offer yet?
