Installation

Manual Installation

Install globally via npm:

npm install -g @rawveg/ollama-mcp

Installing in Other MCP Applications

To install the Ollama MCP Server in other MCP-compatible applications (like Cline or Claude Desktop), add the following configuration to your application's MCP settings file:

{
  "mcpServers": {
    "@rawveg/ollama-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@rawveg/ollama-mcp"
      ]
    }
  }
}

The settings file location varies by application:

Claude Desktop: claude_desktop_config.json in the Claude app data directory
Cline: cline_mcp_settings.json in the VS Code global storage

Contributing

Contributions are welcome! Please feel free to submit a Pull Request.

However, this does not grant permission to incorporate this project into third-party services or commercial platforms without prior discussion and agreement. While I previously accepted contributions (such as a Dockerfile and related README updates) to support integration with services like Smithery, recent actions by a similar service — Glama — have required a reassessment of this policy.

Glama has chosen to include open-source MCP projects in their commercial offering without notice or consent, and subsequently created issue requests asking maintainers to perform unpaid work to ensure compatibility with their platform. This behaviour — leveraging community labour for profit without dialogue or compensation — is not only inconsiderate, but ethically problematic.

As a result, and to protect the integrity of this project and its contributors, the licence has been updated to the GNU Affero General Public License v3.0 (AGPL-3.0). This change ensures that any use of the software — particularly in commercial or service-based platforms — must remain fully compliant with the AGPL's terms and obtain a separate commercial licence. Merely linking to the original source is not sufficient where the project is being actively monetised. If you wish to include this project in a commercial offering, please get in touch first to discuss licensing terms.
