longbook MCP server

A financial memory for your AI. longbook keeps your recurring money — subscriptions, insurance, EMIs, school fees, domains, renewals — as a meticulous, machine-readable memory that the AI you already use can read, fill, and build on. Your AI gathers from your statements and emails; longbook remembers, checks, and shows you every change for approval.

  • Native apps for iPhone and Mac (SwiftUI), one $38 purchase with a 7-day refund, one purchase unlocks every platform; longbook Cloud, $4 a month, covers what uses the server.

  • Your data is a folder of plain files you own — self-describing (llms.txt + a JSON Schema), synced through your own iCloud Drive.

  • Designed so it cannot hold secrets: no card numbers, no CVVs, no credentials — the schema and validators refuse them, which is what makes everything else safe.

  • Connects to your AI over MCP — locally for desktop AI apps, hosted for ChatGPT and phones.

Status

The domain engine (packages/core), the Swift data layer (packages/swift-core), the accounts and entitlements backend (supabase/) and the native app (apps/longbook) are all in place; the app runs on both platforms and ships through App Store Connect. Docs describe what exists today.

Path

What it is

packages/core

The domain engine — dates, money, selectors, insights, the data-policy scanner; pure TypeScript, no runtime deps

packages/swift-core

The same data layer in Swift, as a multiplatform package (iOS 17+, macOS 14+) shared by both app targets

packages/swift-design

The design system — colour, type, spacing, and the SwiftUI pieces both apps draw with

packages/mcp

The MCP server — the memory's read and write tools over stdio for the AI on the owner's machine, and the engine behind the hosted twin at longbook.app/mcp, which reads the pushed copy and takes writes as proposals

packages/cards

Self-contained HTML cards over the same numbers — the design system's tokens, exported once, feeding a second renderer

supabase/

Accounts, trial clock, entitlements, purchases, the hosted MCP and hosted copy, statement reading, report sharing

apps/longbook

The native SwiftUI app — one target building for iOS and macOS, with the Home Screen widget

apps/longbook-site

The static site at longbook.app — the pages, the guide and schema at stable addresses, and the edge functions behind /mcp and shared reports

    Enables AI tools and agents to share a persistent memory space, so a decision, task, or encrypted secret saved in one client can be searched, recalled, and handed off from another. It also tracks goals day by day, moves unfinished work between sessions, and keeps exports, trash recovery, and per-account isolation under the user's control.
