arma3-wiki MCP server

An MCP (stdio) server that serves the Arma 3 wiki data generated by acemod/arma3-wiki on its dist branch, plus bundled scripting tutorials in tutorials/.

The server keeps its own shallow clone of upstream dist in wiki/ (ignored). It clones on first start, refreshes in the background on every start and every 24 hours while running. The refresh_wiki tool forces an update. If a refresh fails, it keeps serving the cached data.

Install (any PC)

git clone https://github.com/ScottTMConnors/arma3-wiki-mcp.git
cd arma3-wiki-mcp
python -m venv .venv
.venv/Scripts/python -m pip install -r requirements.txt   # Linux/macOS: .venv/bin/python

Register it with a client, e.g. a project .mcp.json:

{ "mcpServers": { "arma3-wiki": {
    "command": "E:/Storage/repos/arma3-wiki-mcp/.venv/Scripts/python.exe",
    "args": ["E:/Storage/repos/arma3-wiki-mcp/server.py"] } } }

command = "E:/Storage/repos/arma3-wiki-mcp/.venv/Scripts/python.exe"
args = ["E:/Storage/repos/arma3-wiki-mcp/server.py"]
