Let AI Agents Read and Write Your Board: The Baton Board MCP Server

The promise of Baton Board is one board where humans and AI agents stay in sync. The Chrome extension is how you send things to your board. The MCP server is how your AI agents do — directly, without copy-paste. It lets an MCP-capable assistant (like Claude Desktop or Claude Code) read and write the very same board you use, by working with your local data file.

It's the most "AI-era" piece of the product: your agent stops handing you text to paste and starts updating your cockpit itself.

What MCP is, briefly

MCP (the Model Context Protocol) is a standard way for AI assistants to use external tools. An MCP "server" exposes a set of actions an agent can call. The Baton Board MCP server exposes your board as a set of safe, structured actions — so an agent can add tasks, log a KPI, mark a habit, and more, with your board as the source of truth.

13 tools, covering the whole board

The server gives agents a complete, structured way to work with a board:

• Read: get a board, list boards, list widgets, list tasks, search the board, get the agenda of upcoming deadlines.
• Write: add a task, bulk-add tasks, complete a task, add a note, record a KPI value, mark a habit, update a goal.

Every write is create-if-missing (the agent doesn't have to set up widgets first) and tagged as coming from AI, so your activity log shows exactly what the agent did.

Local-only and zero-trust by design

This is the part that matters most, and it's deliberate:

• It runs locally over stdio. The server talks to your agent on your own machine. It does not go over the network.
• Your board never leaves your device. There is intentionally no remote/SSE version — a hosted server would mean your board data leaving your machine, which would break the local-first, zero-trust promise. Deep AI work happens locally.
• Atomic writes with a backup. Every change is written atomically, and the server keeps a one-generation backup of your data file before writing — so an agent's mistake is recoverable.

In other words, you get the power of an agent that can update your board, without giving up the privacy model that makes Baton Board what it is.

Who this is for

The main Baton Board app is for everyone — AI is entirely optional. The MCP server is the sharp edge for developers and AI-native users who already run agents and want those agents writing to a real board instead of dumping text. Same product, two layers: a dashboard anyone can use, and an agent integration for people who live in AI tools.

A concrete loop

Imagine asking your assistant to plan a project. Instead of printing a list for you to copy, it calls bulk_add_tasks and the tasks appear on your board. Later it calls record_kpi with this week's number and mark_habit for the days you shipped. You open your board and it's already current — updated by your agent, on your machine, in the same place you work by hand.

Frequently asked questions

What is the Baton Board MCP server?

A local server that lets MCP-capable AI assistants (such as Claude Desktop or Claude Code) read and write the same board you use, by working with your local data file.

What can agents do with it?

Thirteen tools in total: read a board, list boards/widgets/tasks, search, and get the agenda; and write — add or bulk-add tasks, complete tasks, add notes, record KPIs, mark habits, and update goals.

Does my board data leave my device?

No. The server runs locally over stdio and there is intentionally no remote/SSE version — your board stays on your machine, in keeping with the zero-trust design.

What happens if an agent makes a mistake?

Writes are atomic, and the server keeps a one-generation backup of your data file before each write, so changes are recoverable.

Is the MCP server part of Pro?

Yes — it's included with Pro at no extra cost (there's no separate tier), verified with your license. Pro also covers unlimited boards, the analytics widgets, the AI assistant, sync, and the desktop app.

Pricing

Free covers one customizable board with the six core widgets, export/import, automatic backups, board-wide search, and eight languages. Pro (¥980/month or ¥9,800/year) unlocks unlimited boards, the analytics widgets (KPI, goal, habit, agenda, activity), the AI assistant, end-to-end sync, the desktop app, the MCP server, and deep customization. A ¥14,800 lifetime license is available. Polar handles payments and worldwide taxes.

Try it

If you already work with AI agents, give them a real board to write to. Set up Baton Board, connect the local MCP server, and let your agents keep your cockpit current — without your data ever leaving your machine.
