Connect Claude Code, Cursor & Windsurf to 2,600+ enterprise data sources — databases, APIs, files, SSH, messaging, and more. One binary. One YAML config.

What is OE MCP?

OE MCP is a standalone binary that implements the Model Context Protocol (MCP). Define your connectors in a single oe-mcp.yaml file and expose them all as tools to your AI coding assistant — no code, no separate servers, no per-connector installs.

Replace 50+ individual MCP servers with one config file.

Quick Start

1. Create your config file (oe-mcp.yaml)

2. Add to Claude Code (~/.mcp.json)

{
  "mcpServers": {
    "oe-mcp": {
      "command": "npx",
      "args": ["@openenterprise/oe-mcp", "--stdio", "/path/to/oe-mcp.yaml"]
    }
  }
}

3. Reload Claude Code — your connectors appear as tools automatically.
