Prompts MCP Server

Instructions

Implementation Reference

• src/tools.ts:264-278 (handler)

  The primary handler for the 'delete_prompt' MCP tool. Validates the 'name' argument, calls fileOps.deletePrompt, and returns a success message.

  private async handleDeletePrompt(args: ToolArguments): Promise<CallToolResult> {
    if (!args.name) {
      throw new Error('Name is required for delete_prompt');
    }
    
    await this.fileOps.deletePrompt(args.name);
    return {
      content: [
        {
          type: 'text',
          text: `Prompt "${args.name}" deleted successfully`,
        } as TextContent,
      ],
    };
  }

• src/fileOperations.ts:85-94 (helper)

  Core helper function that performs the actual file deletion by constructing the filepath and using fs.unlink.

  async deletePrompt(name: string): Promise<boolean> {
    const fileName = this.sanitizeFileName(name) + '.md';
    const filePath = path.join(this.promptsDir, fileName);
    try {
      await fs.unlink(filePath);
      return true;
    } catch (error) {
      throw new Error(`Prompt "${name}" not found`);
    }
  }

• src/tools.ts:67-80 (schema)

  Input schema definition for the 'delete_prompt' tool, specifying the required 'name' string parameter.

  {
    name: 'delete_prompt',
    description: 'Delete a prompt by name',
    inputSchema: {
      type: 'object',
      properties: {
        name: {
          type: 'string',
          description: 'Name of the prompt to delete',
        },
      },
      required: ['name'],
    },
  },

• src/tools.ts:144-145 (registration)

  Registration in the handleToolCall switch statement that routes 'delete_prompt' calls to the handler.

  case 'delete_prompt':
    return await this.handleDeletePrompt(toolArgs);
