What the publisher says

From the Peil repository's README, as published. We do not edit it. Read it on GitHub

Peil MCP server

<!-- Ownership proof for the official MCP registry: it fetches https://pypi.org/pypi/peil-mcp/json and requires this exact line in the README (which PyPI serves as the package description) to match the name in server.json. Do not remove or reword it. -->

mcp-name: app.peil/peil-mcp

Connect Peil to Claude (or any MCP client): log hours, draft invoices from unbilled hours, and check where you stand — from a prompt.

  • Website: https://peil.app
  • Docs: https://peil.app/en/docs/mcp
  • Source: https://github.com/Luminc/peil-mcp

The server is a pure client of Peil's public API. It authenticates with a scoped API key you create in Peil under Settings → Developer (Pro).

Draft-by-default

draftinvoice only ever creates a draft — nothing is sent to your clients. Sending is a separate tool (sendinvoice) that also requires the separate invoices:send permission on your key. A key without that permission can never email anything on your behalf.

Tools

Reads (read)

Hours (timesheet:write)

Clients (clients:write)

Invoices (invoices:write)

Client-facing email (invoices:send — irreversible, always confirm first)

1. Create your key

In Peil: Settings → Developer → create a key with the permissions you want. Start with read + Log hours + Draft invoices; leave Send invoices off unless you truly want an assistant emailing clients. You'll paste this key into your assistant's config as PEILAPIKEY below.

2. Install the server

The easy way — no clone, no install (once peil-mcp is published to PyPI):

uvx peil-mcp          # runs the latest release on demand
# or, with pipx:
pipx run peil-mcp

→ Your launch command is uvx peil-mcp (or pipx run peil-mcp). Skip to step 3. Everything below is only needed if you're running from source (e.g. before the first release, or to hack on it).

From source

You need Python 3.11 or newer and a local copy of this mcp-server/ folder. Check your Python with python3 --version.

Shortened. The full README is on GitHub.
