Common questions

Is Ledgr safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: DATABASE_URL

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.4) reached the registry 29 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

Ledgr

Self-hostable personal finance app with automatic bank sync and AI agent support.

Ledgr connects to your bank accounts through Plaid or SimpleFIN, automatically syncs and categorizes transactions, and gives you budgets, investment tracking, bill detection, and financial reports — all running on your own server with your own data.

It also exposes an MCP server, so AI assistants like Claude can query your finances through natural conversation.

You: "How much did I spend on dining out last month?"

Claude: Based on your transactions, you spent $342.18 on dining out in April...

Querying your finances from Claude Code via MCP

Features

Automatic bank sync — connect 12,000+ banks via Plaid (real-time webhook sync or scheduled polling), or via SimpleFIN if you'd rather not use a Plaid developer account
Smart categorization — four-tier pipeline: your rules > merchant defaults > Plaid categories > AI fallback
Budgets — set monthly budgets by category, track progress in real time
Investment tracking — portfolio holdings, performance history, and allocation breakdowns, synced automatically from Plaid or SimpleFIN
Recurring bill detection — automatically identifies subscriptions and recurring charges
Financial reports — spending, income, net worth, and category trends over time
AI agent interface (MCP) — query your finances from Claude Code, Claude Desktop, Cursor, or any MCP client
In-app AI chat — ask questions about your finances right from the dashboard
BYOK AI — bring your own API key (OpenAI, Anthropic, Google, or local models) for chat and categorization
CSV/OFX/QFX import & CSV export — for accounts not supported by Plaid, and for getting your data out
Self-hosted — Docker Compose with PostgreSQL, your data never leaves your server

Monthly budgets by category, tracked against real spending

Spending, income, cash flow, trends, and net worth reports

Quick Start

Requires Docker and Docker Compose.

curl -fsSL https://raw.githubusercontent.com/KenTaniguchi-R/ledgr/main/scripts/install.sh | sh

This creates a ledgr/ directory, downloads docker-compose.yml, and starts the app.

Prefer to see the steps first?

mkdir ledgr && cd ledgr

curl -O https://raw.githubusercontent.com/KenTaniguchi-R/ledgr/main/docker-compose.yml docker compose up -d

Visit http://localhost:4200, create an account, and start exploring.

On first boot, Ledgr generates an encryption key and session secret and stores them in the app data volume. Back up that volume (or the `/data/encryption-key` file) along with your database — losing the key means losing access to encrypted data like Plaid and SimpleFIN tokens. Prefer to manage the key yourself? Set ENCRYPTION_KEY in a .env file (see Configuration) and it takes precedence.

Add your Plaid keys to .env to enable bank sync — see Connect Your Bank below (or skip the keys and use SimpleFIN). The app works without either via CSV import.

Connect Your Bank

Sign up at dashboard.plaid.com and get your client_id and secret from Developers > Keys
Add them to a .env file next to your docker-compose.yml (start from .env.example if you don't have one):

   PLAID_CLIENT_ID=your_client_id

PLAID_SECRET=your_secret PLAID_ENV=production # or sandbox for fake data

3. Restart: `docker compose restart`

In the app, go to Accounts > Link Bank to connect via Plaid

Plaid's free trial plan includes 10 production connections and unlimited sandbox access. After that, the Launch plan is pay-as-you-go with no contract. Don't have Plaid keys yet? The app still works — import transactions via CSV and add Plaid later.

Connect any of 12,000+ banks through Plaid

Or connect via SimpleFIN

SimpleFIN works out of the box — no developer account or .env changes needed.

Get a SimpleFIN Bridge account and generate a Setup Token from your bridge provider
In the app, go to Accounts > Link Bank and choose the SimpleFIN option
Paste your Setup Token to connect

SimpleFIN has no webhooks, so accounts sync on a daily schedule (SCHEDULER_SIMPLEFIN_SYNC_CRON, see Configuration) instead of in real time. Investment holdings sync the same way as they do for Plaid.

Connect Your AI Agent

Ledgr ships with a built-in MCP server and plugin support.

First, enable the MCP endpoint in your .env and restart:

MCP_ENABLED=true

Then pick your tool:

Claude Code

/plugin marketplace add KenTaniguchi-R/ledgr

/plugin install ledgr@ledgr

Codex CLI

codex plugin marketplace add KenTaniguchi-R/ledgr

OpenCode — add to opencode.json:

"$schema": "https://opencode.ai/config.json", "plugin": ["ledgr"] }

OpenClaw

openclaw plugins install ledgr --marketplace KenTaniguchi-R/ledgr

Hermes

hermes plugins install KenTaniguchi-R/ledgr

Other MCP clients (Cursor, Windsurf, Cline, etc.)

Point any MCP-compatible client to your Ledgr instance:

http://localhost:4200/api/mcp

On first connection, Ledgr redirects you through an OAuth flow to authorize access.
