Ansible Knowledge MCP Server — module and role discovery, documentation, and skill generation for AI agents
SaferSkills independently audited ansible-know-mcp (MCP Server) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Module discovery, documentation search, and skill generation for AI agents via the Model Context Protocol.
Ansible Know is the learn layer for AI agents working with Ansible:
Together with Ansible Devtools MCP (build) and AAP MCP (deploy), this enables the full autonomous cycle: learn -> build -> deploy.

uvx ansible-know-mcpUsing pip:
pip install ansible-know-mcpRequirement: ansible-core must be installed in the same Python environment (provides ansible-doc).
# Project-scoped
claude mcp add ansible-know -- uvx ansible-know-mcp
# Available in all projects
claude mcp add --scope user ansible-know -- uvx ansible-know-mcpAdd to .vscode/mcp.json in your workspace:
{
"servers": {
"ansible-know": {
"command": "uvx",
"args": ["ansible-know-mcp"],
"type": "stdio"
}
}
}The server communicates over stdio by default:
uvx ansible-know-mcpRun as a standalone HTTP server for shared/remote access:
# HTTP on default port (8080)
ansible-know-mcp --transport http
# Custom host and port
ansible-know-mcp --transport http --host 10.0.0.1 --port 9090
# Via environment variables (useful for containers)
export ANSIBLE_KNOW_TRANSPORT=http
export ANSIBLE_KNOW_PORT=8080
ansible-know-mcpConnect from any MCP client using the streamable HTTP URL: http://<host>:8080/mcp
Security: HTTP mode has no built-in authentication. Deploy behind a reverse proxy with authentication/authorization, or use only on trusted networks.
Build and run from source:
docker build -t ansible-know-mcp .
docker run -p 7860:7860 ansible-know-mcpConnect from any MCP client using the streamable HTTP URL: http://localhost:7860/mcp

Deploy as a remote MCP server on Hugging Face Spaces:
README.md must include YAML frontmatter: ---
title: Ansible Know MCP
emoji: "\U0001F4DA"
sdk: docker
app_port: 7860
---Dockerfile builds and starts the server automaticallyNote: Free-tier Spaces sleep after inactivity. MCP clients will see connection errors until the Space wakes up (~30-60s cold start). Use a paid Space or a keep-alive ping for production use.
Custom domain (optional):
know.ansible.ar)<owner>-<space-name>.hf.spaceEnvironment variables (set in Space settings):
| Variable | Required | Description |
|---|---|---|
ANSIBLE_KNOW_SKILLS_DIR | No | Defaults to ./skills/ (ephemeral in container) |
ANSIBLE_KNOW_NO_PUBLIC_GALAXY | No | Set to 1 to disable public Galaxy fallback |
The Dockerfile works with any container platform (Fly.io, Railway, Cloud Run, etc.):
docker build -t ansible-know-mcp .
docker run -p 8080:7860 ansible-know-mcpOverride defaults with environment variables:
docker run -p 9090:9090 \

pytestThe skill generation approach in this project was inspired by AnsibleClaw by Michael Tao — a skill generation framework that converts Ansible modules into portable AI agent skill packages.
