Ansible Knowledge MCP Server — module and role discovery, documentation, and skill generation for AI agents

Ansible Know MCP Server

Module discovery, documentation search, and skill generation for AI agents via the Model Context Protocol.

What It Does

Ansible Know is the learn layer for AI agents working with Ansible:

• Galaxy collection discovery — search 2000+ collections by keyword, ranked by download count
• Multi-server Galaxy support — query public Galaxy, private Automation Hub, and AAP Gateway in parallel
• Module and role documentation — structured parameter specs, examples, and metadata with Galaxy fallback
• Documentation search — find conceptual guides from Ansible's AI-friendly docs
• Collection management — auto-install collections and get collection-level overviews
• Skill generation — create ready-to-use skill packages that teach agents how to use specific modules and roles
• Resources and prompts — browse skills, doc sources, and Galaxy servers; pre-built templates for playbook review, module explanation, and role generation

Together with Ansible Devtools MCP (build) and AAP MCP (deploy), this enables the full autonomous cycle: learn -> build -> deploy.

Installation

Using uvx (recommended):

uvx ansible-know-mcp

Using pip:

pip install ansible-know-mcp

Requirement: ansible-core must be installed in the same Python environment (provides ansible-doc).

Usage

Claude Code

# 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-mcp

VS Code / Cursor

Add to .vscode/mcp.json in your workspace:

{
  "servers": {
    "ansible-know": {
      "command": "uvx",
      "args": ["ansible-know-mcp"],
      "type": "stdio"
    }
  }
}

Any MCP client

The server communicates over stdio by default:

uvx ansible-know-mcp

HTTP Transport

Run 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-mcp

Connect 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.

Multi-server Galaxy Support

Ansible Know reads [galaxy_server.*] sections from ansible.cfg (resolved in standard order: ANSIBLE_CONFIG env, ./ansible.cfg, ~/.ansible.cfg, /etc/ansible/ansible.cfg):

# ansible.cfg
[galaxy_server.automation_hub]
url = https://hub.example.com/api/galaxy/
token = my-token

[galaxy_server.public_galaxy]
url = https://galaxy.ansible.com/api/

• Token auth, basic auth, and per-server TLS verification
• search_collections queries all configured servers in parallel, merging results with source attribution
• get_module_doc / get_role_doc Galaxy fallback tries servers in priority order
• Public Galaxy is appended as a final fallback; opt out with ANSIBLE_KNOW_NO_PUBLIC_GALAXY=1
• Per-server env var overrides: ANSIBLE_GALAXY_SERVER_{NAME}_{KEY} (matches ansible-core behavior)
• View configured servers via the galaxy://servers resource

Configuration

Environment Variable	Description	Default
ANSIBLE_KNOW_SKILLS_DIR	Where to write generated skills	./skills/
ANSIBLE_KNOW_DOC_SOURCES	JSON dict of doc manifest sources	Built-in ansible-core source
ANSIBLE_KNOW_GALAXY_URL	Galaxy API base URL	https://galaxy.ansible.com
ANSIBLE_KNOW_SKIP_UPDATE_CHECK	Set to 1 to disable PyPI version check at startup	(not set)
ANSIBLE_KNOW_NO_PUBLIC_GALAXY	Set to 1 to suppress auto-appending public Galaxy	(not set)

Upgrading

Method	Command
uvx	uvx --upgrade ansible-know-mcp
pip	pip install --upgrade ansible-know-mcp
Claude Code	uvx --upgrade ansible-know-mcp then restart Claude Code
VS Code / Cursor	uvx --upgrade ansible-know-mcp then reload window
Local dev	git pull && uv sync

Note: uvx caches the installed version and does not auto-upgrade on new releases. To always run the latest version (at the cost of slower startup): claude mcp add ansible-know -- uvx --upgrade ansible-know-mcp

Development

git clone https://github.com/leogallego/ansible-know-mcp.git
cd ansible-know-mcp
uv venv && source .venv/bin/activate
uv pip install -e ".[dev]"
pytest
