avenir-mcp: an unofficial MCP server for YNAB

🇬🇧 avenir-mcp (*avenir* is French for *the future*) lets an AI agent read your YNAB plan

and help you plan what comes next.

🇫🇷 avenir-mcp permet à un agent IA de lire votre plan YNAB et de vous aider

à préparer la suite.

Ask Claude — or any MCP client — about your plan in plain words. Read-only by default; every change is previewed, confirmed by you, and can be undone.

Install

You need a YNAB personal access token: YNAB → Account Settings → Developer Settings → New Token.

Claude Desktop, no terminal: drop the file the button downloads onto Settings → Extensions, then paste your token on that screen.

Claude Code, one command with your token in it:

claude mcp add avenir-mcp --env YNAB_API_KEY=your-token -- uvx avenir-mcp

Both install it read-only. Cursor, LM Studio, VS Code, Windows, changes to your plan (AVENIR_MCP_WRITE=1) and every option: Install · Configuration.

▶ Watch the 20-second tour

Both come from an invented demo plan, replayed by python -m docsgen: every figure is what avenir-mcp answers today.

What you can ask

Understand a month — "Which category is overspent this month?" → get_monthly_summary
Prepare a spend — "Will I go below zero before December?" → forecast_balance
Pay off a debt — "When will my debts be paid off if I put 500 a month on them?" → get_debt_payoff_plan
Tidy the transactions — "Categorise what is pending." → suggest_categories, applied after your yes
Find one transaction — "Which transaction is my 86.40 receipt from the 12th?" → find_transactions
Reconcile an account — "My bank shows 3,440.80. Does YNAB agree?" → reconcile_account
Change something — "Move 30 from Tennis to Restaurants." → move_money, previewed, confirmed, and undone by undo_operation

Every tool, with a real answer: Reference · Use cases.

Missing a question? Have an idea? Tell us the question you would like to ask your budget in Discussions → Ideas; help with using avenir-mcp is in Discussions → Q&A. Never post a real amount, a real account or your token.

Why avenir-mcp

Tools for tasks, not endpoints. One tool classifies a month, one reconciles an account.
Read-only by default. The tools that change a plan are registered only if you enable them.
Preview, confirm, undo. A write waits for your yes; undo_operation reverts it.
Answers an agent can read. Currency units, typed answers, bank text treated as untrusted.
Verified. 100 % line and branch coverage, and a real agent on an invented plan: 25/25.

Claude Code plugin

plugin/ is avenir-mcp as a Claude Code plugin: Claude Code asks for your token, keeps it out of sight, and starts the server from the plugin's own locked environment. From a clone: claude --plugin-dir plugin.

The plugin	What
runs	`uv run --locked --project` the plugin's folder, which starts the release `plugin/pyproject.toml` pins, and nothing else. No script of its own, no build step, no hook, no shell
contacts	`pypi.org` and `files.pythonhosted.org`, to install that release and the versions `plugin/uv.lock` pins, the first time; then `api.ynab.com`, with your token, as avenir-mcp always does
writes	the environment `uv` resolves inside the plugin's folder, and `uv`'s own cache. Nothing elsewhere
changes in your plan	nothing. It starts avenir-mcp read-only: `AVENIR_MCP_WRITE` is not set, so the tools that change a plan are never registered

Development

git clone https://github.com/mathbeal/avenir-mcp && cd avenir-mcp

uv sync just check # lint, types, tests at 100 % coverage, vocabulary, lockfile just docs-serve # the documentation, live just evaluate # a real agent on the demo plan (uses your Claude plan)

Read AGENTS.md and CONTRIBUTING.md before opening a pull request. Security reports: SECURITY.md. Also: ARCHITECTURE.md, ROADMAP.md, GOVERNANCE.md and the code of conduct.

Built and tested against YNAB's API v1.88.0; a weekly YNAB API drift check fails when YNAB publishes a new version. Self-checked on every change against YNAB's API terms of 2025-05-28 (naming, attribution, YNAB's own image, a personal token for its owner only, the hourly limit); a weekly job turns that badge red when they change.

Privacy Policy

avenir-mcp is a program you run yourself, not a service: its publisher runs no server and receives none of your data. Your token is read from the environment, kept in memory as a secret value and sent only to YNAB; your plan's data is fetched when a tool needs it and returned to your agent, so the model provider behind your MCP client sees it too. What is handled, how long it is kept and how to erase it: https://avenir-mcp.pages.dev/avenir-mcp/project/privacy/.
