Implementation Reference

• src/index.ts:455-469 (handler)

  The main handler function for the 'rm' tool. It executes the 'ollama rm {name}' command using execAsync and returns the stdout or stderr as text content, or throws an error if it fails.

  private async handleRemove(args: any) {
    try {
      const { stdout, stderr } = await execAsync(`ollama rm ${args.name}`);
      return {
        content: [
          {
            type: 'text',
            text: stdout || stderr,
          },
        ],
      };
    } catch (error) {
      throw new McpError(ErrorCode.InternalError, `Failed to remove model: ${formatError(error)}`);
    }
  }

• src/index.ts:192-206 (registration)

  Registration of the 'rm' tool in the listTools response, including name, description, and input schema.

  {
    name: 'rm',
    description: 'Remove a model',
    inputSchema: {
      type: 'object',
      properties: {
        name: {
          type: 'string',
          description: 'Name of the model to remove',
        },
      },
      required: ['name'],
      additionalProperties: false,
    },
  },

• src/index.ts:195-205 (schema)

  Input schema definition for the 'rm' tool, specifying an object with a required 'name' string property.

  inputSchema: {
    type: 'object',
    properties: {
      name: {
        type: 'string',
        description: 'Name of the model to remove',
      },
    },
    required: ['name'],
    additionalProperties: false,
  },

• src/index.ts:272-273 (handler)

  Dispatch case in the main CallToolRequestSchema handler that routes 'rm' tool calls to the handleRemove function.

  case 'rm':
    return await this.handleRemove(request.params.arguments);
