MidOS MCP Community Library — Knowledge, Skills, and Research as MCP tools.
Install once, connect to any AI client.
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/).
midos-mcp serveStart the MCP server with your preferred transport.
| 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 configGenerate ready-to-paste JSON config for any supported MCP client.
midos-mcp healthCheck server health: knowledge base stats, vector store status, dependencies.
midos-mcp keysManage API keys for tiered access control.
Tiers: dev (free), pro ($10/mo), admin.
| 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 |
The server locates the MidOS knowledge base:
MIDOS_ROOT environment variable (recommended)CLAUDE.md + knowledge/If you installed via pip, auto-detect won't find the knowledge base. Either:
Verify with midos-mcp health — it shows the detected root and knowledge counts.
| 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 |
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 |
| 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.
