sattle.me assistant (MCP server)

An MCP server that makes a sattle.me merchant's invoices (numbered in the merchant's one series, with their lines and VAT, a payment link payable until their due date and a PDF) and follows their payment, with the assistant's secret key alone (sattleme_ak_…, created in the sattle.me app). It never spends: every invoice pays the merchant's wallet.

Two ways to run it, one code:

  • In Claude Desktop, on the merchant's own computer: the key never leaves it.

  • Hosted on mcp.sattle.me, for any AI app that connects to MCP servers with OAuth (Claude, ChatGPT…).

Work in progress: not released yet.

Path

What it is

SPEC.md

The assistant's protocol: what this server does with its key. Authoritative.

vectors/app/

Records made by the merchant's app, which this server reads and makes alike.

spec/

The integrations' specification (sattleme/checkout-spec), pinned: SPEC.md names it.

vendor/checkout-node/

The code of sattleme/checkout-node this server builds on, pinned and unchanged.

In Claude Desktop

  1. In the sattle.me app, create an assistant (« Réglages › Assistants ») and copy its key (sattleme_ak_…).

  2. Open sattleme-assistant-<version>.mcpb (a release of this repository): Claude Desktop installs it and asks for the key, which it keeps in the computer's secret store, and optionally the invoices' language, the time zone and a folder for the PDFs.

  3. Ask Claude: « Fais une facture à Dupont SA pour 3 jours de conseil à 1200 CHF, échéance à 30 jours. » It previews the invoice, asks you to confirm the total, then makes it.

Its tools: business_profile, preview_invoice, create_invoice (the only one that is not read-only), list_invoices, invoice_status, invoice_pdf. Another MCP client starts node dist/src/stdio.js with the settings of src/stdio.ts in its environment.

Hosted

https://mcp.sattle.me/mcp, added in the AI app as a connector (a custom connector in Claude, an app or connector in ChatGPT): the app asks the merchant to connect, and the merchant pastes the assistant key on sattle.me's own page, never in the conversation. How it is run: docs/HOSTING.md.

Development

Node 22 or later. npm ci, then npm run check (pinned copies, lint, format, types, tests, build). npm run bundle writes the Claude Desktop bundle in build/ (the official mcpb tool, pinned). The lockfile is written by npm 11 (npx npm@11 install): npm 10 installs from it (npm ci), but fails to resolve it anew.
