tf2-wiki-mcp

An MCP server that exposes the Team Fortress Wiki to LLM clients (Claude Desktop, Claude Code, Cursor, VS Code) over stdio.

Not affiliated with Valve Corporation or the Team Fortress Wiki contributors. Team Fortress 2 is a trademark of Valve Corporation. This is unofficial fan tooling.

What it does

Gives an LLM live, accurate access to TF2 wiki content so it stops guessing at weapon stats, patch notes, and cosmetic details.

• Generic wiki access — search, fetch pages, get summaries, list recent changes.

• TF2 domain tools — structured weapon stats, class loadouts, cosmetic lookup, event item lists, patch notes.

Tools

Plus: resource tf2wiki://main, prompts analyze_loadout and compare_weapons.

Installation

Requires uv (which manages the Python toolchain for you). Once installed, uvx tf2-wiki-mcp will fetch and run the server on demand — no manual clone needed.

Standard config works in most MCP clients:

{
  "mcpServers": {
    "tf2-wiki-mcp": {
      "command": "uvx",
      "args": ["tf2-wiki-mcp"],
      "env": {}
    }
  }
}

Add the standard config above to claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Windows: %APPDATA%\Claude\claude_desktop_config.json

Restart Claude Desktop. The TF2 wiki tools appear in the tool picker.

claude mcp add tf2-wiki-mcp -- uvx tf2-wiki-mcp

Add to ~/.codex/config.toml:

[mcp_servers.tf2-wiki-mcp]
command = "uvx"
args = ["tf2-wiki-mcp"]

See the Codex MCP docs.

Or add the standard config to ~/.cursor/mcp.json.

Add the standard config to your Gemini CLI settings.json per the Gemini CLI MCP guide.

Or via the VS Code CLI:

code --add-mcp '{"name":"tf2-wiki-mcp","command":"uvx","args":["tf2-wiki-mcp"],"env":{}}'

See the VS Code MCP guide for details.

Or via the CLI:

code-insiders --add-mcp '{"name":"tf2-wiki-mcp","command":"uvx","args":["tf2-wiki-mcp"],"env":{}}'

Or manually:

1. Open the GitHub Copilot Chat window.

2. Click the tools icon (🛠️) → + Add Server.

3. Fill in: Server ID tf2-wiki-mcp, Type stdio, Command uvx, Arguments tf2-wiki-mcp.

4. Save.

See the Visual Studio MCP docs.

{
  "mcpServers": {
    "tf2-wiki-mcp": {
      "command": "uvx",
      "args": ["tf2-wiki-mcp"],
      "env": {},
      "type": "local",
      "tools": ["*"]
    }
  }
}

Add this in repository settings under Copilot → Coding agent. See the Copilot Coding Agent MCP docs.

Development

Run from a local clone instead of PyPI:

git clone https://github.com/yusufaf/tf2-wiki-mcp
cd tf2-wiki-mcp
uv sync --dev
uv run pytest              # offline, uses recorded cassettes
uv run pytest --live       # also hits the real wiki

To point an MCP client at the local checkout:

{
  "mcpServers": {
    "tf2-wiki-mcp": {
      "command": "uv",
      "args": ["run", "--directory", "/absolute/path/to/tf2-wiki-mcp", "tf2-wiki-mcp"]
    }
  }
}
