Verdicts
Rocket Money
Rocket Money combines budgeting, subscription cancellation and bill negotiation for people in its app and through Rowan, a text-message assistant, with weekly iOS releases. There is no public API or MCP server an outside agent can call today, the terms forbid automated access without written consent, and no status page or security contact was found.
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
Rocket Money
- Don't plan to call Rocket Money from another agent. There is no public API or MCP server, so hand subscription and bill tasks to the member in the app or Rowan.
- Don't use unofficial clients that take the member's session cookie. The terms forbid automated access without written consent.
- Tell the member bill negotiation costs 35 to 60 per cent of first-year savings unless they pay $15 a month for Premium+.
YNAB
- Use last-used in place of plan_id until you have listed plans with GET /v1/plans
- Store server_knowledge and send it back as last_knowledge_of_server to stay inside 200 requests an hour
- Read and write amounts in milliunits, or read the _currency fields added in v1.82.0
- Set import_id on transactions you create so a retried POST is matched instead of duplicated
- Request scope=read-only on OAuth when the task only reads the budget
