A stdio bridge that connects Claude Desktop to the eyeot ERP's native MCP-over-HTTP server, exposing roughly 600 business operations auto-generated from OpenAPI: CRM quotes, invoice lookups, stock alerts, maintenance schedules, HR leave requests, IT ticketing, document management, plus modules for POS, delivery routing, recruitment, BPM, field service, and supply chain MRP. Authentication uses OAuth 2.1 with PKCE for interactive sessions or long-lived API keys for automation. All business logic, RBAC, and audit logging live server-side. The bridge itself is around 290 lines of Python with zero runtime dependencies. Reach for this if you're already running eyeot ERP and want to query or modify records conversationally without building custom integrations. Works with self-hosted deployments via a base URL override.
eyeot-mcpOfficial stdio ↔ HTTP bridge for the eyeot ERP MCP server.
~600 business tools, one pip install.
Landing page · Docs · PyPI · Issues
pip install eyeot-mcp # 1. install the bridge
eyeot-mcp login # 2. authenticate via browser (OAuth Device Flow)
Then paste into your Claude Desktop config:
{
"mcpServers": {
"eyeot": {
"command": "eyeot-mcp"
}
}
}
Restart Claude Desktop. Done. Ask: "List my last 5 invoices."

The eyeot ERP exposes ~600 business actions — CRM, sales, stock, maintenance, HR, finance, IT service management, GED, RGPD compliance, plus 6 V2 marketplace modules (POS, delivery & routing, recruitment, BPM, field service, supply chain) — as MCP tools over HTTPS.
But Claude Desktop, Cursor, and most local agents only speak MCP over stdio.
eyeot-mcp is the missing piece between them.

Zero business logic in the bridge. Everything happens server-side — auth, RBAC, audit logging, license enforcement, multi-tenant isolation, idempotency. The CLI is ~290 lines of Python standard library. You can audit it in 10 minutes.
After install, your MCP client gets access to actions like:
| Domain | Try saying… |
|---|---|
| 💼 CRM | "Create a quote for ACME — 10 units of PROD-001 at standard tariff." |
| 📊 Sales | "List my last 5 invoices and their payment status." |
| 📦 Stock | "Which products in Lyon site are below the critical threshold?" |
| 🔧 Maintenance | "Which equipment is overdue for preventive maintenance this week?" |
| 👥 HR | "Show me pending leave requests for my team." |
| 💰 Finance | "What's the revenue forecast for Q3 by business unit?" |
| 🎫 IT support | "Open a ticket: VPN is down for the marketing team, P1." |
| 📄 GED | "Find all signed NDAs for partner XYZ." |
| 🧠 Intelligence | "Customer-health distribution across all active accounts." |
| 🧾 POS / Caisse | "Today's Z-report total for the Lyon register." |
| 🚚 Delivery | "Optimize today's route for vehicle TL-204 and notify recipients." |
| 🧑💼 Recruitment | "Shortlist candidates for the senior developer posting." |
| ⚙️ Process / BPM | "Which approval tasks are pending in my inbox?" |
| 🏗️ Field service | "Schedule a site intervention for client XYZ next Tuesday." |
| 🔩 Supply chain | "Run MRP and list the components to reorder this week." |
…and ~590 more, auto-generated from the OpenAPI spec.

| Command | Description |
|---|---|
eyeot-mcp | Start the stdio bridge using saved credentials (default mode — what Claude Desktop runs) |
eyeot-mcp login | Browser-based OAuth Device Authorization Grant |
eyeot-mcp logout | Revoke refresh token server-side, delete local credentials |

eyeot-mcp as a child process, exchanges JSON-RPC 2.0 over its stdin/stdout pipes.POSTs the JSON to ${base_url}/api/v1/mcp with Authorization: Bearer <token>.2024-11-05 and auto-generates ~600 tools from the OpenAPI spec — initialize, tools/list, tools/call all work exactly as MCP clients expect.No state in the bridge. No protocol translation beyond transport. No surprises.

The eyeot ERP backend is a separate, proprietary product of Eyeot Software. This bridge is open-source so anyone can audit it, fork it, package it for their distro, or use it as a reference for building their own MCP clients.
Multi-tenant, AI-native ERP for SMBs. Built to be operated by AI agents from day one.
Every action you can do in the UI, you can do via this bridge.
