Documentation
Actual MCP Server
Talk to your budget. Run it anywhere. Trust it in production.
Actual MCP Server is a Model Context Protocol server that connects any MCP-compatible AI assistant (such as LibreChat, LobeChat, Claude Desktop, and more) directly to your self-hosted Actual Budget instance. Ask natural language questions, create transactions, analyse spending, and manage your entire budget without ever opening the Actual Budget UI.

Why this project?
Most Actual Budget MCP implementations are simple stdio bridges designed for single-user, local use with Claude Desktop. This project goes further:
- 71 tools, the most comprehensive coverage available. Accounts, transactions, categories, payees, tags, notes, rules, budgets, batch operations, bank sync, and more. Covers the reachable Actual Budget API with no genuine gaps.
- HTTP and stdio transport. Runs as a real remote server for LibreChat/LobeChat (
--http), or as a direct local process for Claude Desktop (--stdio). No Docker or HTTP server is needed for local use. - 6 exclusive ActualQL-powered tools. Search and summarise transactions by month, amount, category, or payee using Actual Budget's native query engine. Aggregated results, no raw data dumped into the AI context window.
- Multi-budget switching at runtime. Configure multiple budget files and let the AI switch between them mid-conversation with
actual_budgets_switch. - Multi-user ready with OIDC. Secure every session with JWKS-validated JWTs and per-user budget ACLs. No shared tokens required.
- Production-grade reliability. Connection pooling (up to 15 concurrent sessions), automatic retry with exponential backoff, and a full test suite (unit + E2E + integration).
Verified working with LibreChat, LobeChat, and Claude Desktop. All 71 tools tested end-to-end. Any MCP-compatible client should work.

Quick Start
Prerequisites
- Actual Budget server running (local or remote)
- Your Budget Sync ID: Actual → Settings → Show Advanced Settings → Sync ID
- Node.js 22+ (npm method) or Docker
Option A: Docker (recommended)
docker run -d \
--name actual-mcp-server-backend \
-p 3600:3600 \
# Use the same URL you type in your browser to open Actual Budget:
# http://localhost:5006 (if Actual Budget runs on the same machine)
# http://192.168.1.50:5006 (if it runs on another machine on your network)
# https://actual.yourdomain.com (if you use a domain name)
# http://actual:5006 (if both containers share a Docker network; use container name)
-e ACTUAL_SERVER_URL=http://localhost:5006 \
-e ACTUAL_PASSWORD=your_password \
-e ACTUAL_BUDGET_SYNC_ID=your_sync_id \
-e MCP_SSE_AUTHORIZATION=your_secret_token \
-v actual-mcp-data:/app/data \ # required, see note below
-v actual-mcp-logs:/app/logs \
ghcr.io/agigante80/actual-mcp-server:latest
Why the
/app/datavolume is required: Actual Budget does not expose a REST API. The official@actual-app/apilibrary (used internally by this server) works by downloading a local copy of your budget data, running all queries on that local copy, then syncing changes back. The/app/datavolume gives the container a persistent, writable place to store that local copy (it is the directory the image creates and owns as the runtime user). Without it the container has nowhere to write and will fail on startup. See the Actual API docs for details.actual-mcp does not need to run on the same machine as Actual Budget. You can have Actual Budget on one server and actual-mcp on another - as long as
ACTUAL_SERVER_URLpoints to your Actual Budget instance, everything works.
Verify it's running:
# Quick health check
curl http://localhost:3600/health
# Expected: {"status":"ok","transport":"http","version":"..."}
# Full MCP handshake (also verifies your token)
curl -s -X POST http://localhost:3600/http \
-H "Authorization: Bearer your_secret_token" \
-H "Content-Type: application/json" \
-H "Accept: application/json, text/event-stream" \
-d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"cli-test","version":"1.0"}}}' \
| python3 -m json.tool
# Success: JSON response with "protocolVersion" and "serverInfo"
# Wrong token: {"error": "Unauthorized"}
# Server not running: curl: (7) Failed to connect
Also available on Docker Hub: agigante80/actual-mcp-server:latest
Option B: Docker Compose
git clone https://github.com/agigante80/actual-mcp-server.git
cd actual-mcp-server
cp .env.example .env # fill in ACTUAL_SERVER_URL, ACTUAL_PASSWORD, ACTUAL_BUDGET_SYNC_ID
docker compose --profile production up -d # production: MCP server listens on :3600
# or
docker compose --profile dev up -d # dev mode with hot-reload
The compose file defines only the
devandproductionprofiles. The MCP server listens on:3600directly: there is no bundled reverse proxy and no bundled Actual Budget server, so pointACTUAL_SERVER_URLat your own Actual instance. For TLS, enable native HTTPS withMCP_ENABLE_HTTPS=true(plusMCP_HTTPS_CERTandMCP_HTTPS_KEY), or front the server with your own reverse proxy.
Option C: npm (HTTP server)
# Quick start via npx (no clone needed):
ACTUAL_SERVER_URL=http://localhost:5006 \
ACTUAL_PASSWORD=your_password \
ACTUAL_BUDGET_SYNC_ID=your-sync-id \
MCP_SSE_AUTHORIZATION=your_token \
npx actual-mcp-server --http
# Or clone for development / custom config:
git clone https://github.com/agigante80/actual-mcp-server.git
cd actual-mcp-server
npm install
cp .env.example .env # fill in required values
npm run build
npm run dev -- --http
Server starts at http://localhost:3600/http by default (the listen port is MCP_BRIDGE_PORT, default 3600).
Option D: stdio (Claude Desktop native, no Docker or HTTP server needed)
The stdio transport runs the MCP server as a child process. Claude Desktop spawns it directly and communicates over stdin/stdout. No network port, no auth token, no Docker required. No cloning needed: npx downloads and caches the package automatically.
Add to claude_desktop_config.json (see docs/guides/MCP_CLIENTS_SETUP.md for config file location and all client options):
{
"mcpServers": {
"actual-budget": {
"command": "npx",
"args": ["-y", "actual-mcp-server", "--stdio"],
"env": {
"ACTUAL_SERVER_URL": "http://localhost:5006",
"ACTUAL_PASSWORD": "your_actual_password",
"ACTUAL_BUDGET_SYNC_ID": "your-sync-id-here",
"MCP_BRIDGE_DATA_DIR": "/absolute/path/to/data-dir"
}
}
}
}
No token needed. stdio runs as a local process owned by your user. The transport itself is the security boundary. All 71 tools are available.
MCP_BRIDGE_DATA_DIRshould be an absolute path. Without one, the data directory resolves relative to wherever the client spawns the process, which can be unpredictable. The directory is created automatically on first run.
Option E: Unraid (Community Applications)
Actual MCP Server is published in the Unraid Community Applications store: ca.unraid.net/apps/actual-mcp-server. This runs the HTTP transport, the right choice for LibreChat, LobeChat, and other remote MCP clients.
Install it from the Apps tab (Community Applications):
- Open the Apps tab and search for
actual-mcp-server, then click Install. - Fill in Actual server URL, Actual server password, and Actual server Sync ID (the Sync ID is in Actual Budget: open the budget, Settings, Show advanced settings, Sync ID).
- Set a strong MCP auth token. Generate one with
openssl rand -hex 32. A blank token disables all HTTP authentication and exposes your financial data unauthenticated on the LAN, so this is required (see Transport & Authentication). - Leave PUID=99 and PGID=100 (
nobody:users) so the container can write the appdata Data and Logs directories, then start it. - Reach the health endpoint via the container's WebUI link (port
3600); point your MCP client athttp://[server-ip]:3600/httpwith the Bearer token.
The Unraid template lives in unraid/actual-mcp-server.xml. For the publishing workflow see docs/UNRAID_CA_PUBLISHING.md.
Connect an AI client
LibreChat / LobeChat: add to librechat.yaml (or LobeChat MCP plugin settings):
mcpServers:
actual-mcp:
type: "streamable-http"
url: "http://actual-mcp-server-backend:3600/http"
headers:
Authorization: "Bearer YOUR_TOKEN_HERE"
serverInstructions: true
timeout: 600000
See docs/guides/AI_CLIENT_SETUP.md for full LibreChat, LobeChat, network, and HTTPS/TLS proxy setup.
Claude Desktop via HTTP (when the server is already running as a Docker container):
{
"mcpServers": {
"actual-budget": {
"command": "npx",
"args": [
"-y",
"mcp-remote",
"http://localhost:3600/http",
"--header",
"Authorization: Bearer YOUR_TOKEN_HERE"
]
}
}
}
Claude Desktop via stdio (native, no HTTP server needed; see Option D above):
{
"mcpServers": {
"actual-budget": {
"command": "node",
"args": ["/absolute/path/to/actual-mcp-server/dist/src/index.js", "--stdio"],
"env": {
"ACTUAL_SERVER_URL": "http://localhost:5006",
"ACTUAL_PASSWORD": "your_password",
"ACTUAL_BUDGET_SYNC_ID": "your-sync-id",
"MCP_BRIDGE_DATA_DIR": "/absolute/path/to/actual-mcp-server/actual-data"
}
}
}
}
See docs/guides/MCP_CLIENTS_SETUP.md for all options (including Cursor, VS Code, Gemini CLI), Linux/NVM path fixes, and troubleshooting.
Upgrading
Docker (Option A)
docker pull ghcr.io/agigante80/actual-mcp-server:latest
docker stop actual-mcp-server-backend
docker rm actual-mcp-server-backend
# Re-run the original docker run command with the same flags and volumes
Also available on Docker Hub: docker pull agigante80/actual-mcp-server:latest
Docker Compose (Option B)
docker compose pull
docker compose --profile production up -d
npm / cloned repo (Option C)
git pull
npm install
npm run build
# Then restart the server
npx / stdio (Options C & D)
If you run npx actual-mcp-server without a globally installed version, npx fetches the latest from the registry automatically. But if you previously installed it globally (npm install -g actual-mcp-server), the global install takes precedence, so you must upgrade it explicitly:
# Upgrade the global install
npm install -g actual-mcp-server
# Or force the registry version without touching your global install
npx actual-mcp-server@latest --http
For Claude Desktop (stdio), restart Claude after upgrading.

Transport & Authentication
The server supports two transport modes:
| Mode | Flag | Use case | Auth |
|---|---|---|---|
| HTTP | --http | LibreChat, LobeChat, Docker, multi-user deployments | Bearer token or OIDC |
| stdio | --stdio | Claude Desktop, Cursor, local single-user use | None (OS process isolation) |
The two modes are mutually exclusive. Pass exactly one flag when starting the server.
stdio transport
stdio is the simplest way to connect Claude Desktop directly to Actual Budget. The MCP server runs as a child process; Claude Desktop spawns it, communicates over stdin/stdout using NDJSON (the MCP wire format), and the process exits cleanly when Claude Desktop closes.
Key properties of stdio mode:
- No network port. The transport is a pipe, not a socket.
- No auth token. Process ownership is the security boundary.
- All logs go to stderr so they never corrupt the JSON-RPC framing on stdout
- The process exits when stdin closes (Claude Desktop shutting down)
- All 71 tools are available, identical to HTTP mode
Start manually to verify:
cd /path/to/actual-mcp-server
ACTUAL_SERVER_URL=http://localhost:5006 \
ACTUAL_PASSWORD=your_password \
ACTUAL_BUDGET_SYNC_ID=your-sync-id \
node dist/src/index.js --stdio
Send a test request (keep stdin open with sleep):
{ echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}'; sleep 5; } \
| ACTUAL_SERVER_URL=http://localhost:5006 ACTUAL_PASSWORD=your_password ACTUAL_BUDGET_SYNC_ID=your-sync-id \
node dist/src/index.js --stdio 2>/dev/null
Claude Desktop config (claude_desktop_config.json):
{
"mcpServers": {
"actual-budget": {
"command": "node",
"args": ["/absolute/path/to/actual-mcp-server/dist/src/index.js", "--stdio"],
"env": {
"ACTUAL_SERVER_URL": "http://localhost:5006",
"ACTUAL_PASSWORD": "your_actual_password",
"ACTUAL_BUDGET_SYNC_ID": "your-sync-id-here",
"MCP_BRIDGE_DATA_DIR": "/absolute/path/to/actual-mcp-server/actual-data"
}
}
}
}
Path must be absolute. Claude Desktop does not inherit shell
PATH, sonodemust also be absolute if you use NVM or a non-standard install:/home/youruser/.nvm/versions/node/v22.x.x/bin/node.
See docs/guides/MCP_CLIENTS_SETUP.md for all connection options (stdio native, mcp-remote via HTTP/HTTPS), other clients (Cursor, VS Code, Gemini CLI, Claude Code), Linux path fixes, and troubleshooting.
HTTP transport
HTTP transport uses the /http endpoint (StreamableHTTP) with optional Bearer token or OIDC authentication.
Static Bearer token (single-user)
# Generate a token
openssl rand -hex 32
# Add to .env
MCP_SSE_AUTHORIZATION=your_token_here
Clients send: Authorization: Bearer your_token_here
OIDC (multi-user)
AUTH_PROVIDER=oidc
OIDC_ISSUER=https://sso.yourdomain.com
OIDC_RESOURCE=your-client-id # must match 'aud' JWT claim
OIDC_SCOPES= # leave empty for Casdoor
See AI Client Setup, OIDC for AUTH_BUDGET_ACL format and Casdoor notes.

@actual-app/api - Validation: Zod (runtime types + JSON Schema for tool inputs)
- Transports: Express + StreamableHTTP (
--http) ·StdioServerTransport(--stdio) - Logging: Winston with daily rotation (all output routed to stderr in stdio mode)
Every Actual API call goes through the withActualApi() wrapper in src/lib/actual-adapter.ts, which handles init/shutdown lifecycle, retry (3 attempts, exponential backoff), and concurrency limiting. See docs/ARCHITECTURE.md for full design documentation.

Wardn source review notes
Reviewed upstream package version: actual-mcp-server 0.7.11 from package.json, VERSION, and npm. The package target preserves the documented stdio launch from the importer and source docs: npx -y actual-mcp-server --stdio. HTTP deployment is documented through --http, Docker, Docker Compose, and self-hosted /http; it is represented as optional CLI/config metadata rather than a hosted remote endpoint.
