  • This package is the MCP server (required). Install with pip install mcp-ollama-python.
  • MCP Ollama Manager is the optional VS Code UI to manage that server. Prefer it if you use VS Code and want status bar controls, model sidebar, and log viewing without editing JSON by hand.

You can also wire this server into any MCP client (Windsurf, Cursor, Claude Desktop, etc.) without the extension — see Quick Start below.


What It Does

Connect your local LLMs to any MCP-compatible AI assistant. No cloud APIs needed.

Tool What it does
ollama_chat Chat with any local model (multi-turn, tool-calling)
ollama_generate Generate text completions
ollama_embed Create vector embeddings
ollama_list List installed models
ollama_show Inspect model details
ollama_pull Download new models
ollama_delete Remove models
ollama_ps List running models

Quick Start

Prerequisites: Python 3.10+, Ollama running locally

pip install mcp-ollama-python

Option A — VS Code with the companion extension (recommended for VS Code)

  1. Install MCP Ollama Manager from the Marketplace
  2. Ensure mcp-ollama-python is installed (the extension can offer Install Now if missing)
  3. Command Palette → MCP Ollama: Configure ServerMCP Ollama: Start Server

Details: extension docs · repo

Option B — Any MCP client (Windsurf / VS Code MCP / Cursor / …)

Add to your MCP config (e.g. mcp_config.json):

{
  "mcpServers": {
    "ollama": {
      "command": "py",
      "args": ["-m", "mcp_ollama_python"],
      "disabled": false
    }
  }
}

Restart your editor — done. Your AI assistant can now use local Ollama models.

Try It

Type in your AI assistant's chat:

Security Threat model, host validation, opt-in execute

Security (v1.0.8)

  • ollama_execute is opt-in — set OLLAMA_EXECUTE_ENABLED=1; shell/bash removed
  • OLLAMA_HOST validation — loopback by default; set OLLAMA_ALLOW_REMOTE_HOST=1 for LAN/remote Ollama
  • No HTTP redirects — reduces SSRF risk toward internal endpoints

Details: docs/SECURITY.md

Changelog

1.0.8

  • Security hardening: host validation, execute tool gating, env allowlist, input limits
  • Fixed __version__ mismatch with package version
  • Added tests/test_security.py and docs/SECURITY.md
