Finance Toolkit
500+ transparent financial methods calculated from raw statements, not third-party endpoints.
Beschreibung vom Entwickler (englisches Original)
Work with your Crunch Accounting books: expenses, receipts, invoices, clients, suppliers and banking
Diese drei werden nie zu einer Punktzahl zusammengefasst: Meinungen, Messungen und Beliebtheit sind verschiedene Dinge.
Für diesen Server haben wir noch keine Zusammenfassung in einfacher Sprache geschrieben. Unten stehen die Fakten, die wir aus der Registry gelesen haben.
Wähle die KI-App, die du nutzt, und kopiere die Einstellungen.
MCP_TRANSPORT, CRUNCH_CLIENT_ID, CRUNCH_CLIENT_SECRET, CRUNCH_REDIRECT_URI, CRUNCH_REFRESH_TOKEN, CRUNCH_ALLOW_WRITES, CRUNCH_ALLOW_DELETES, CRUNCH_ALLOW_EMAIL, CRUNCH_TOOLSETS, CRUNCH_FILES_DIR, CRUNCH_AUDIT_LOGAls geheim markierte Werte sind Schlüssel zu deinem Konto. Gib sie nie weiter und füge sie nie in einen Chat ein.

An open-source Model Context Protocol server for Crunch Accounting, the UK online accounting service. It lets Claude and other AI assistants read and, if you allow it, update your expenses, receipts, invoices, clients, suppliers and bank accounts, all from one small Docker container.

"How's the business looking this month?"
*You have £18,240 across your two bank accounts and £312 on the company credit card. Three sales invoices are unpaid, £7,800 in total. INV-0042 to Example Client Ltd (£2,400) is 12 days overdue; the other two aren't due yet. On the spending side, four September expenses have no receipt attached and one bill from Example Hosting Ltd (£96) is still unpaid. Want me to draft a polite chaser for INV-0042, or list the expenses that are missing receipts?*
Ask about your business in plain English. The assistant picks from 70 tools to look things up and, if you allow it, make changes. Some examples:
ghcr.io/mattoddie/crunch-mcp) for linux/amd64 and linux/arm64, about 21 MB. It's a single static Go binary on a distroless base, with no shell or package manager, running as a non-root user. It serves Streamable HTTP for a long-running service, or stdio for docker run -i. You can also run the binary on its own.dry_run: true to show the request it would send, with a field-by-field diff for updates, without changing anything. CRUNCH_AUDIT_LOG records each change in a JSON Lines audit log..mcpb) for macOS, Windows and Linux, with a settings form and no Docker needed.search, fields and limit to fetch only what's needed.Using Claude Desktop? Download the extension bundle for your computer from the latest release, open it, enter your Crunch client ID and ask Claude to *"log in to Crunch"*. See Claude Desktop. The steps below set up the Docker server for every other client.
You need Docker, a Crunch account, Crunch API access and an MCP client such as Claude Code.
1. Get API access. Apply for access to Crunch's public API through the application form linked from Crunch's developer documentation. Crunch sends you a client ID, and a client secret if you're set up as a confidential client. There's no sandbox, so a free Crunch account is a good place to try things. Getting started has the details.
2. Set up the server.
mkdir crunch-mcp && cd crunch-mcp
curl -fsSLO https://raw.githubusercontent.com/mattoddie/crunch-mcp/main/compose.yaml curl -fsSL https://raw.githubusercontent.com/mattoddie/crunch-mcp/main/example.env -o .env
openssl rand -hex 32)
3. Log in to Crunch and start the server.
docker compose run --rm -p 127.0.0.1:8976:8976 crunch-mcp login # open the URL it prints and click Allow
docker compose up -d
If your browser isn't on the Docker host, the page after Allow won't load. That's fine: copy the URL from the address bar and paste it into the terminal.
4. Connect your assistant.
claude mcp add --transport http crunch http://<docker-host>:8080/mcp \
--header "Authorization: Bearer "
Now ask *"How's my business doing?"* in Claude Code.
Using Claude Desktop, VS Code, Cursor or Codex? See Connecting MCP clients. Prefer not to run a service? Use stdio mode with docker run -i or the local binary.
crunch-mcp is listed in the official MCP Registry as io.github.mattoddie/crunch-mcp, so clients that install servers from the registry can set it up for you, with the Docker image in stdio mode or an extension bundle.
Out of the box the assistant can look but not touch. To let it make changes, add these to .env:
CRUNCH_ALLOW_WRITES=true # create and update expenses, invoices, clients, suppliers, payments, attachments…
CRUNCH_ALLOW_DELETES=true # also allow deleting records and removing payments (needs writes) CRUNCH_ALLOW_EMAIL=true # also allow emailing invoices and payment reminders to customers (needs writes) CRUNCH_TOOLSETS=account,reference,expenses,invoices,clients,suppliers # optional: expose fewer tools CRUNCH_AUDIT_LOG=stderr # optional: log every change (or an absolute file path; see docs/configuration.md)
The login needs matching scopes, so log in again after turning on writes or deletes:
docker compose stop
docker compose run --rm -p 127.0.0.1:8976:8976 crunch-mcp login docker compose up -d
Ask for a dry run first when it matters: *"Record that receipt, but show me a dry run first."*
Read Security before turning on writes for your real books.
| Toolset | What's covered |
|---|---|
account | Login status and the OAuth login flow, the logged-in user, company details (VAT number and scheme, addresses) and a one-call business overview |
reference | The values Crunch expects: expense types, VAT types, payment methods, countries, open accounting periods, directors and employees |
banking | Bank accounts and credit cards: balances, details, payments recorded against them, opening balances, default accounts, archiving |
clients | Clients (the customers you invoice): list, look up, create, update and delete |

raw | An escape hatch that calls any Crunch public API endpoint |
See the [tool reference](docs/tools.md) for every tool and argument. Ready-made prompts like business_health_check, record_receipt and chase_overdue_invoices chain the tools together for common jobs.
The docs are also published at [crunch-mcp.mattoddie.dev/docs](https://crunch-mcp.mattoddie.dev/docs/), with search.
