ollama-mcp

An MCP (Model Context Protocol) server that exposes local Ollama instances as tools for Claude Code.

Lets Claude offload code generation, drafts, embeddings, and quick questions to your local GPUs.

Setup

1. Run the setup script:

   bash setup.sh
   

   This creates a venv, installs dependencies, generates a machine-specific config.json, and registers the MCP server with Claude Code.

   Note: setup.sh uses cygpath and targets Windows (Git Bash / MSYS2). On Linux/macOS, replace the cygpath -w calls with the paths directly, or register manually:

   claude mcp add ollama -s user -- /path/to/.venv/bin/python /path/to/src/ollama_mcp/server.py
   

2. Restart Claude Code.

Tools

Tool	Description
ollama_generate	Single-turn prompt → response
ollama_chat	Multi-turn conversation
ollama_embed	Generate embedding vectors
ollama_list_models	List models on your Ollama instances

Configuration

Copy config.example.json to config.json and fill in your machine details, or let setup.sh generate it interactively.

Requirements

• Python 3.10+
• Ollama 0.4.0+ running on at least one machine
• Claude Code with MCP support

Development

pip install -e ".[dev]"
pytest tests/ -v

Troubleshooting

Problem	Cause	Fix
config.json not found	Setup not run	Run bash setup.sh
404 on embed calls	Ollama < 0.4.0	Upgrade Ollama (ollama update)
Cannot connect to...	Ollama not running on target host	Start Ollama: ollama serve or check Docker
Request timed out	Large model / slow hardware	Increase timeout in config.json, or pass timeout parameter
OFFLINE in list_models	Host unreachable	Check network, firewall, Ollama port 11434
cygpath: command not found	Running setup.sh on Linux/macOS	See setup note above
