What is OE MCP Server?
OE MCP Server is a standalone binary that implements the Model Context Protocol (MCP) and exposes your enterprise data sources as tools that AI apps can use directly.
Connect Claude Code, Cursor, Windsurf, or Claude Desktop to your PostgreSQL database, local filesystem, GitHub, Slack, Google Drive, SSH servers, and more — without writing any integration code.
- No code. Define connectors in a single YAML file.
- 45+ connector categories. 2,600+ enterprise systems supported out of the box.
- Two transport modes.
--stdio for Claude Code VS Code / desktop apps; --serve for Cursor, Windsurf, and cloud deployments.
- Persistent memory. Built-in
memory_set / memory_get / memory_list / memory_delete tools — context survives across sessions.
- Self-hosted. Runs on your own machine. No cloud dependency. Own your data.
Quick Start via npm (Recommended)
No binary download needed — npx handles everything automatically:
macOS / Linux:
{
"mcpServers": {
"oe-mcp": {
"type": "stdio",
"command": "npx",
"args": ["-y", "@openenthrium/oe-mcp", "--stdio", "/path/to/oe-mcp.yaml"]
}
}
}
Windows: use npx.cmd instead of npx:
{
"mcpServers": {
"oe-mcp": {
"type": "stdio",
"command": "npx.cmd",
"args": ["-y", "@openenthrium/oe-mcp", "--stdio", "C:\\path\\to\\oe-mcp.yaml"]
}
}
}
Note: -y tells npx to skip the install confirmation prompt. Without it, npx waits for keyboard input and the MCP connection never opens.
Add this to ~/.mcp.json (Claude Code) and reload VS Code. Done.
Download (Standalone Binary)
Prefer a standalone binary? Download for your platform:
Quick Start (Binary)
1. Download the binary for your OS
2. Create your config file (oe-mcp.yaml)
connectors:
- name: my-postgres
type: postgresql
host: localhost
port: 5432
database: mydb
user: postgres
password: secret
- name: my-codebase
type: filesystem
basePath: /home/user/projects/myapp
memory:
- key: project_context
value: "This is our main application database."
3. Connect your AI app — see sections below for Claude Code, Cursor, and Windsurf.
Claude Code (VS Code Extension)
Option A — via npm (recommended, no binary download needed):
macOS / Linux:
{
"mcpServers": {
"oe-mcp": {
"type": "stdio",
"command": "npx",
"args": ["-y", "@openenthrium/oe-mcp", "--stdio", "/path/to/oe-mcp.yaml"]
}
}
}
Windows:
{
"mcpServers": {
"oe-mcp": {
"type": "stdio",
"command": "npx.cmd",
"args": ["-y", "@openenthrium/oe-mcp", "--stdio", "C:\\path\\to\\oe-mcp.yaml"]
}
}
}
Note: -y skips npx's install confirmation prompt — without it, npx blocks waiting for keyboard input and the MCP connection never opens.
Option B — via downloaded binary:
{
"mcpServers": {
"oe-mcp": {
"type": "stdio",
"command": "/path/to/oe-mcp-win.exe",
"args": ["--stdio", "/path/to/oe-mcp.yaml"]
}
}
}
Reload VS Code — the MCP tools appear automatically in Claude Code.
Cursor / Windsurf / Claude Desktop (HTTP mode)
Start the server manually, then point your AI app at the URL.
oe-mcp-win.exe --serve --port 4040 oe-mcp.yaml
In Cursor settings → MCP → Add server:
http://localhost:4040/mcp
In Claude Desktop claude_desktop_config.json:
{
"mcpServers": {
"oe-mcp": {
"url": "http://localhost:4040/mcp"
}
}
}
Cloud Deployment (MCP as a Service)
Deploy oe-mcp-linux to any cloud server — AWS EC2, fly.io, Railway, DigitalOcean — and multiple developers connect to it via URL. No binary needed on each developer machine.
./oe-mcp-linux --serve --port 4040 /etc/oe-mcp/oe-mcp.yaml
Each developer adds to their Cursor / Windsurf:
http://your-server.com:4040/mcp

Each connector exposes a set of tools prefixed with the connector name. Examples:
| Connector | Tools |
|---|
postgresql / mysql / mongodb | query — run SQL or aggregation queries |
filesystem | list_dir, read_file, write_file, append_file, delete_file, make_dir, file_info, search_files |
github | list_repos, get_file, create_issue, list_issues, list_prs, get_pr, search_code |
slack | list_channels, post_message, get_messages, get_thread |
ssh | execute_command, upload_file, download_file, list_files |
gdrive | list_files, get_file, create_file, update_file, search_files |
rest-api | request — any HTTP method against any endpoint |
Built-in memory tools available in every session:
| Tool | Description |
|---|
memory_set | Store a key-value pair that persists across sessions |
memory_get | Retrieve a stored value by key |
memory_list | List all stored key-value pairs |
memory_delete | Remove a stored key |
Memory is stored in oe-mcp-memory.json next to your oe-mcp.yaml and survives restarts.
Example usage in Claude Code:
"Remember that our main database is on prod-db.company.com"
→ Claude calls memory_set with key main_db_host and value prod-db.company.com
Binary vs Node.js Mode
The standalone binary works for all connector categories except Oracle, MSSQL, SQLite, and Snowflake — these use native C++ addons that cannot be bundled into a single executable.
If you need any of these four, run with Node.js instead:
git clone https://github.com/enthrium/open-enthrium-ai-mcp-server.git
cd open-enthrium-ai-mcp-server/server
yarn install
node mcp/index.js --stdio /path/to/oe-mcp.yaml
node mcp/index.js --serve --port 4040 /path/to/oe-mcp.yaml
All other connectors (PostgreSQL, MySQL, MongoDB, Redis, S3, Slack, GitHub, REST API, SSH, filesystem, etc.) work directly with the binary — no Node.js required.
