Implementation Reference

• src/tools/copy.ts:10-22 (handler)

  The core handler function that performs the model copy operation using the Ollama client's copy method and formats the response.

  export async function copyModel(
    ollama: Ollama,
    source: string,
    destination: string,
    format: ResponseFormat
  ): Promise<string> {
    const response = await ollama.copy({
      source,
      destination,
    });
  
    return formatResponse(JSON.stringify(response), format);
  }

• src/schemas.ts:184-191 (schema)

  Zod schema defining the input parameters for the ollama_copy tool: source model name, destination name, and optional format.

  /**
   * Schema for ollama_copy tool
   */
  export const CopyModelInputSchema = z.object({
    source: z.string().min(1),
    destination: z.string().min(1),
    format: ResponseFormatSchema.default('json'),
  });

• src/tools/copy.ts:24-51 (registration)

  Tool registration definition including name, description, input schema (for MCP/JSON schema), and handler that validates inputs using Zod schema and calls the copyModel function. This is auto-loaded by the autoloader.

  export const toolDefinition: ToolDefinition = {
    name: 'ollama_copy',
    description:
      'Copy a model. Creates a duplicate of an existing model with a new name.',
    inputSchema: {
      type: 'object',
      properties: {
        source: {
          type: 'string',
          description: 'Name of the source model',
        },
        destination: {
          type: 'string',
          description: 'Name for the copied model',
        },
        format: {
          type: 'string',
          enum: ['json', 'markdown'],
          default: 'json',
        },
      },
      required: ['source', 'destination'],
    },
    handler: async (ollama: Ollama, args: Record<string, unknown>, format: ResponseFormat) => {
      const validated = CopyModelInputSchema.parse(args);
      return copyModel(ollama, validated.source, validated.destination, format);
    },
  };
