OE MCP Server · @openenterprise/oe-mcp

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.
