📝

Write a YAML config

Define your connectors in oe-mcp.yaml — database credentials, file paths, API tokens. One file, any number of connectors.

🔌

Connect your AI app

Point Claude Code, Cursor, or Windsurf at the binary. Every connector is exposed as tools your AI can call directly from the IDE.

💬

Ask in plain language

Query your database, read files, post to Slack, search GitHub — all from inside your IDE, with no custom integration code.

Setup

Two ways to connect

Choose stdio for Claude Code — launched automatically as a child process — or HTTP for Cursor, Windsurf, and cloud deployments.

🤖

Claude Code

stdio mode

Claude Code launches the binary automatically as a child process. Add to ~/.mcp.json or your workspace .mcp.json:

{
  "mcpServers": {
    "oe-mcp": {
      "type": "stdio",
      "command": "/path/to/oe-mcp-win.exe",
      "args": [
        "--stdio",
        "/path/to/oe-mcp.yaml"
      ]
    }
  }
}

Reload VS Code — MCP tools appear automatically in Claude Code.

🖥️

Cursor / Windsurf / Cloud

HTTP mode

Start the server once, then point your app at the URL. Deploy to a cloud server to share one endpoint across your team:

# Start the MCP server
oe-mcp-win.exe --serve --port 4040 oe-mcp.yaml
# Listening on http://localhost:4040/mcp

# Cursor: Settings → MCP → Add server
http://localhost:4040/mcp

# Claude Desktop — claude_desktop_config.json
{ "mcpServers": {
"oe-mcp": { "url": "http://localhost:4040/mcp" }
} }

Deploy oe-mcp-linux to EC2, fly.io, or Railway — the whole team connects via one URL, no binary on each machine.

Configuration

oe-mcp.yaml reference

One YAML file defines all your connectors and seeds default memory values. Credentials stay on your machine — nothing is sent anywhere.

connectors:
  - name: production-db
    type: postgresql
    host: db.company.com
    port: 5432
    database: production
    user: readonly
    password: secret

  - name: company-github
    type: github
    token: ghp_...

  - name: source-code
    type: filesystem
    basePath: /home/user/projects

memory:
  - key: team
    value: "Platform Engineering"
  - key: environment
    value: "production"

Built-in

Persistent memory across sessions

Every OE MCP session includes four memory tools. Context persists in oe-mcp-memory.json next to your config — survives restarts and new sessions.

Tool	What it does
memory_set	Store any key-value pair that persists across restarts and new sessions
memory_get	Retrieve a stored value by key
memory_list	List all stored key-value pairs
memory_delete	Remove a stored key permanently

# In Claude Code — just ask in plain language:
"Remember that our main DB is on prod-db.company.com"
# → Claude calls memory_set(key="main_db_host", value="prod-db.company.com")

"What database host did we save last session?"
# → Claude calls memory_get(key="main_db_host") → "prod-db.company.com"

Connectors

2,600+ enterprise systems

Every connector below is available as MCP tools in your AI app. Declare it in oe-mcp.yaml — the binary handles authentication, protocol, and tool exposure.
