What is OE MCP Server?

A standalone binary that implements the Model Context Protocol (MCP) and exposes your enterprise data sources as tools that AI apps can use directly. No code. Define connectors in a single JSON file.

• 45+ connector categories — PostgreSQL, MongoDB, S3, GitHub, Slack, Gmail, SSH, REST API, and more
• Two transport modes — --stdio for Claude Code / Cursor / Windsurf; --serve for cloud or team deployments
• Persistent memory — memory_set / memory_get / memory_list / memory_delete survive across sessions
• Action log — every connector call logged automatically with timestamp, tool, input, and result
• Run AI agents — run_agent executes any OE Runtime SKILL.md agent directly from Claude Code, Cursor, or any MCP client. Manual skills pause for approval via approve_chain.
• Self-hosted — runs on your own machine, no cloud dependency, no call-home

Quick Start via npm (Recommended)

1. Create `oe-mcp.json`:

{

"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." } ] }

2. Add to your AI app's MCP config:

macOS / Linux:

{

"mcpServers": { "oe-mcp": { "type": "stdio", "command": "npx", "args": ["-y", "@openenthrium/oe-mcp", "--stdio", "/path/to/oe-mcp.json"] } } }

Windows:

{

"mcpServers": { "oe-mcp": { "type": "stdio", "command": "npx.cmd", "args": ["-y", "@openenthrium/oe-mcp", "--stdio", "C:\\path\\to\\oe-mcp.json"] } } }

`-y` is required — without it npx blocks waiting for keyboard input and the MCP connection never opens.

3. Reload your AI app — connectors appear as tools automatically.

Ask Claude: _"What connectors do you have access to?"_ to verify.

Built-in Tools

Memory

Persistent memory that survives restarts — stored in oe-mcp-memory.json:

_"Remember that our production database is on prod-db.company.com"_ → Claude calls memory_set

Action Log

Every connector call is logged automatically to oe-mcp-log.json:

Run AI Agents

Execute OE Runtime SKILL.md agents or YAML agents directly from Claude Code, Cursor, or any MCP client — no terminal required:

`run_agent` parameters:

`approve_chain` parameters:

OE MCP looks for oe-config.json in the agent's directory first, then falls back to oe-mcp.json.

Agent Skill Approval Flow

When an agent's skill pipeline includes manual skills, Claude handles the approval loop automatically:

1. Claude calls run_agent → response shows ⏸ Skill awaiting approval with chain_id and skill_name
2. Claude decides — based on your instructions — whether to approve, skip, or abort
3. Claude calls approve_chain → next skill runs or the next manual skill pauses again
4. Repeat until Pipeline complete or Claude aborts

Example instruction to Claude Code: _"Run the OE Skills orchestrator and send a Slack message — skip anything you can't do, abort if it asks for credentials."_

Transport Modes

HTTP mode — start the server, then add the URL to Cursor / Windsurf / Claude Desktop:

oe-mcp-linux --serve --port 4040 /path/to/oe-mcp.json

→ http://your-server.com:4040/mcp
