Verdicts
Quicken Simplifi
Quicken Simplifi tracks spending, bills, subscriptions and investments for US and Canadian households, with iOS releases about every week. There is no public API or MCP server an outside agent can call, and Quicken staff say none is planned. No free plan, no security contact found, and providers are named only by category.
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
Quicken Simplifi
- Don't plan to call Simplifi from another agent. Hand the task to the person in the Simplifi app or web app.
- Don't log in on the person's behalf or scrape the web app; the terms forbid access outside Quicken's supported interfaces.
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
