Implementation Reference

• src/tools/delete.ts:10-20 (handler)

  Core implementation of the ollama_delete tool. Calls ollama.delete({model}) to delete the specified model and formats the response.

  export async function deleteModel(
    ollama: Ollama,
    model: string,
    format: ResponseFormat
  ): Promise<string> {
    const response = await ollama.delete({
      model,
    });
  
    return formatResponse(JSON.stringify(response), format);
  }

• src/tools/delete.ts:22-45 (registration)

  ToolDefinition export that registers the 'ollama_delete' tool, including its name, description, input schema (JSON Schema format), and handler function that validates input using Zod schema and calls the core deleteModel function.

  export const toolDefinition: ToolDefinition = {
    name: 'ollama_delete',
    description:
      'Delete a model from local storage. Removes the model and frees up disk space.',
    inputSchema: {
      type: 'object',
      properties: {
        model: {
          type: 'string',
          description: 'Name of the model to delete',
        },
        format: {
          type: 'string',
          enum: ['json', 'markdown'],
          default: 'json',
        },
      },
      required: ['model'],
    },
    handler: async (ollama: Ollama, args: Record<string, unknown>, format: ResponseFormat) => {
      const validated = DeleteModelInputSchema.parse(args);
      return deleteModel(ollama, validated.model, format);
    },
  };

• src/schemas.ts:176-182 (schema)

  Zod schema for validating input parameters of the ollama_delete tool (model name and optional format). Used in the tool handler for runtime validation.

  /**
   * Schema for ollama_delete tool
   */
  export const DeleteModelInputSchema = z.object({
    model: z.string().min(1),
    format: ResponseFormatSchema.default('json'),
  });
