Ollie

A Go CLI that connects Ollama LLMs to MCP (Model Context Protocol) servers for tool use. Built because I couldn't find what I wanted with existing tools.

Quick Start

Requirements:

• Go 1.21+
• Ollama running locally (http://localhost:11434)

Build:

go build

Run:

./ollie config.json [model]

Default model is qwen3:8b. Override with any Ollama model name.

Configuration

Create a JSON file defining your MCP servers:

{
  "mcpServers": {
    "filesystem": {
      "command": "mcp-server-filesystem",
      "args": ["/path/to/allowed/directory"],
      "env": {
        "DEBUG": "true"
      }
    },
    "disabled-example": {
      "command": "some-server",
      "disabled": true
    }
  }
}

Options:

• command - MCP server executable (required)
• args - Command arguments (optional)
• env - Environment variables (optional)
• disabled - Skip this server (optional)

MCP server commands must be in your PATH.

Usage

Chat history displays in a scrollable viewport. Type in the multi-line text area below, submit with Enter (Ctrl+J for new lines).

Tools depend on which MCP servers you configure. Example with filesystem server:

> What files are in the current directory?
[Calling tool from filesystem server]
Found: main.go, config/, mcp/, ollama/, tools/

Troubleshooting

No servers connected

• Verify MCP server commands are in PATH
• Check command names and arguments in config

Tools not working

• Ensure servers support tools/list and tools/call
• Check tool arguments match expected schema

Ollama errors

• Start Ollama: ollama serve
• Verify model exists: ollama list
