What the publisher says

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

manager-mcp

<!-- mcp-name: io.github.flumpiey/manager-mcp -->

MCP server for self-hosted Manager.io: ask your AI about invoices, balances, and books.

What is Manager.io?

Manager.io is free, self-hosted accounting software for Windows, macOS, and Linux (also available as Cloud Edition). It covers sales, purchases, banking, payroll, and the full ledger, with an HTTP API (/api2) for automation.

This project wires that API into the Model Context Protocol so Cursor, Claude, VS Code Copilot, and other MCP hosts can query your live books in natural language.

What this server does

Default is read-only. You get:

  • 10 read tools - discovery, six searchable collections, seven report shortcuts
  • Task tools (opt-in) - intent-shaped writes such as recordcustomerpayment, issuesalesinvoice, recordcustomerdeposit (register when matching write scopes are set)
  • Deprecated CRUD tools - per-resource create / update / delete still register under scopes until 0.3.0**; prefer task tools
  • raw escape hatch - restores the full CRUD set for advanced use
  • Hard denylist - access tokens, chart of accounts forms, tax/currency, email templates, and similar high-risk paths stay blocked even when writes are on

Transport is stdio. No HTTP server. No global install required if you use uv / uvx.

Branding / icons

  • stdio hosts (Cursor, Claude Desktop via mcp.json): the server advertises Manager branding in MCP serverInfo.icons (embedded PNG data URI, plus a GitHub raw HTTPS fallback).
  • Cursor plugin: .cursor-plugin/plugin.json uses docs/manager-icon.svg.
  • Claude Desktop Extension: pack mcpb/ (includes icon.png). See Installation → Claude Desktop below.
  • Claude.ai remote connectors: Claude.ai ignores serverInfo.icons and uses the root-domain favicon of the connector URL. If you host a remote MCP later, serve docs/favicon.ico at the registrable domain root (e.g. https://acme.com/favicon.ico for https://mcp.acme.com/...).

Requirements

  • Python ≥ 3.10 (pulled in automatically by uvx)
  • uv (provides uvx)
  • A reachable Manager.io API: MANAGERAPIURL + MANAGERAPIKEY

Access token

  1. In Manager, open Settings → Access Tokens.
  2. Create a token and copy the value into MANAGERAPIKEY.
  3. Set MANAGERAPIURL to your API base (desktop often http://127.0.0.1:55667/api2).

manager-mcp sends the token as the X-API-KEY header. Full walkthrough: Access Tokens.

Quick start

Run the PyPI package with uvx:

uvx manager-mcp
