Ollama MCP Server

Instructions

Implementation Reference

• src/index.ts:423-437 (handler)

  The main handler function for the 'list' tool. It runs the 'ollama list' command using execAsync, captures stdout/stderr, and returns it as text content. Errors are thrown as McpError.

  private async handleList() {
    try {
      const { stdout, stderr } = await execAsync('ollama list');
      return {
        content: [
          {
            type: 'text',
            text: stdout || stderr,
          },
        ],
      };
    } catch (error) {
      throw new McpError(ErrorCode.InternalError, `Failed to list models: ${formatError(error)}`);
    }
  }

• src/index.ts:164-172 (schema)

  The schema/declaration for the 'list' tool in the ListTools response, specifying name, description, and empty inputSchema (no parameters required).

  {
    name: 'list',
    description: 'List models',
    inputSchema: {
      type: 'object',
      properties: {},
      additionalProperties: false,
    },
  },

• src/index.ts:268-269 (registration)

  Registration/dispatch in the CallToolRequestSchema handler switch statement, which calls the handleList() method when the tool name is 'list'.

  case 'list':
    return await this.handleList();
