Tool reference

Public contract snapshot: 2026-10-16, MCP commit 86f8b914c33239fbb38ae442ae27f3ca2c490ebc.

Fillfolio exposes ten read-only tools. A connected host may discover a subset because of account eligibility, client grants, or rendering support. Namespaces vary by host.

OAuth scope: mcp:read. The permission column below records internal Fillfolio application grants. Do not request those names as extra OAuth scopes. Spending and budgets need independent per-client permission.

Response envelope

The nine financial tools return structured content and JSON text with asOf, partial, missing, and tool-specific data. Keep missing values and coverage warnings. asOf records response generation, not quote freshness.

{
  "asOf": "2026-10-16T12:00:00.000Z",
  "partial": false,
  "missing": [],
  "data": {}
}

open_fillfolio returns launch text and UI metadata instead of the financial envelope. It advertises ui://fillfolio/dashboard-v4.html with MIME type text/html;profile=mcp-app for supporting hosts. Dashboard sharing
