Common questions

Is MidOS - MCP Community Library safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2026.2.23.1) reached the registry 9 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

midos-mcp

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:

MIDOS_ROOT environment variable (recommended)
Auto-detect: walks up from package location looking for CLAUDE.md + knowledge/
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
