Verdicts

Copilot Money

Copilot Money is a subscription budgeting app with a dated public changelog, a published disclosure policy and iOS releases every few weeks. There is no public API, and its MCP server, read-only and in beta since 15 May 2026, is open only through a waitlist, with no public documentation of its tools or connection.

YNAB

A public OpenAPI 3.1.1 file, a dated changelog and an OAuth read-only scope let an agent read and edit a person's own budget. Each token is limited to 200 requests an hour with no Retry-After, personal access tokens never expire and have no read-only option, and access always starts with a person signing up in a browser.

Before you call either

Copilot Money

  1. Don't plan to call Copilot Money from another agent. The MCP beta is waitlist-only, so ask the person to join at agent.copilot.money and connect it themselves.
  2. Once connected, expect read-only access to categories, transactions, monthly spend and income, recurrings and tags, per the changelog.
  3. Don't treat unofficial Copilot clients that read the local cache or a browser session as Copilot's interface.

YNAB

  1. Use last-used in place of plan_id until you have listed plans with GET /v1/plans
  2. Store server_knowledge and send it back as last_knowledge_of_server to stay inside 200 requests an hour
  3. Read and write amounts in milliunits, or read the _currency fields added in v1.82.0
  4. Set import_id on transactions you create so a retried POST is matched instead of duplicated
  5. Request scope=read-only on OAuth when the task only reads the budget
