MidOS - MCP Community Library

MidOS MCP Community Library — Knowledge, Skills, and Research as MCP tools.

Install once, connect to any AI client.

Install

pip install midos-mcp

Requirement: MidOS knowledge base must be available locally. Set the MIDOS_ROOT environment variable to point to your MidOS installation directory (the one containing knowledge/ and modules/).

export MIDOS_ROOT=/path/to/midos

Quick Start

# Start server (stdio — default for Claude Code, Cursor, etc.)
midos-mcp serve

# Start with HTTP transport
midos-mcp serve --http

# Generate config for your AI client
midos-mcp config --generate claude
midos-mcp config --generate cursor

# Check health
midos-mcp health

Commands

midos-mcp serve

Start the MCP server with your preferred transport.

midos-mcp serve              # stdio (default)
midos-mcp serve --http       # Streamable HTTP on 127.0.0.1:8419
midos-mcp serve --sse        # Legacy SSE transport
midos-mcp serve --http --host 0.0.0.0 --port 9000

Flag	Transport	Use Case
--stdio	stdio	Claude Code, Cursor, Cline (default)
--http	Streamable HTTP	Web clients, remote access
--sse	Server-Sent Events	Legacy clients

midos-mcp config

Generate ready-to-paste JSON config for any supported MCP client.

midos-mcp config --generate claude    # Claude Desktop / Claude Code
midos-mcp config --generate cursor    # Cursor IDE
midos-mcp config --generate cline     # Cline (VS Code)
midos-mcp config --generate windsurf  # Windsurf IDE
midos-mcp config --generate continue  # Continue.dev
midos-mcp config --generate zed       # Zed Editor
midos-mcp config --generate opencode  # OpenCode
midos-mcp config --generate http      # Generic HTTP client

# Write to file
midos-mcp config --generate claude -o mcp-config.json

midos-mcp health

Check server health: knowledge base stats, vector store status, dependencies.

midos-mcp health          # Human-readable output
midos-mcp health --json   # JSON output for scripts

midos-mcp keys

Manage API keys for tiered access control.

midos-mcp keys generate --name "my-app" --tier dev
midos-mcp keys list
midos-mcp keys revoke midos_sk_abc

Tiers: dev (free), pro ($10/mo), admin.

Configuration

Environment Variables

Variable	Default	Description
MIDOS_ROOT	auto-detect	Path to MidOS installation (required)
MIDOS_HOST	127.0.0.1	HTTP server bind host
MIDOS_PORT	8419	HTTP server bind port
MIDOS_TRANSPORT	stdio	Default transport

Root Detection

The server locates the MidOS knowledge base:

1. MIDOS_ROOT environment variable (recommended)
2. Auto-detect: walks up from package location looking for CLAUDE.md + knowledge/
3. Fallback: current working directory

If you installed via pip, auto-detect won't find the knowledge base. Either:

# Option A: Clone the repo and point to it
git clone https://github.com/MidOSresearch/midos.git
export MIDOS_ROOT=./midos

# Option B: Point to an existing MidOS directory
export MIDOS_ROOT=/path/to/your/midos

Verify with midos-mcp health — it shows the detected root and knowledge counts.

Supported Clients

Client	Config File	Transport
Claude Desktop	claude_desktop_config.json	stdio
Claude Code	.mcp.json	stdio
Cursor	.cursor/mcp.json	stdio
Cline	cline_mcp_settings.json	stdio
Windsurf	~/.codeium/windsurf/mcp_config.json	stdio
Continue.dev	~/.continue/config.json	stdio
Zed	~/.config/zed/settings.json	stdio
OpenCode	opencode.json	SSE

Optional Dependencies

# Vector store support (LanceDB + embeddings)
pip install midos-mcp[vector]

# Development tools
pip install midos-mcp[dev]

What's Inside

MidOS exposes 68 MCP tools across 2 tiers:

Tier	Tools	Access
Dev	34 tools	Free — no API key needed, full content, 500 queries/month
Pro	68 tools	$10/mo — security ops, AOTC, orchestration, maker write ops

Capabilities

• Knowledge — Search 46K+ curated chunks across all domains (full content, no truncation)
• Skills — 119 reusable patterns across 16+ technology stacks
• EUREKA — 383 validated improvements with measured ROI
• Truth — 50 verified patches and corrections
• SOTA — 140 state-of-the-art convergence ceilings
• Vector Search — Semantic search via LanceDB + Gemini embeddings (3072-d)

Rate Limits

Tier	Queries/month	Content
Dev	500	Full content (no truncation)
Pro	100,000	Full content + AOTC + ops packs

Invalid or expired API keys silently fall back to Dev tier.

Requirements

• Python 3.10+
• FastMCP 2.x
• MidOS knowledge base (local)
