Implementation Reference

• src/tools/encoding.ts:115-130 (handler)

  The asynchronous handler function that implements the core logic of the encodeHtml tool, replacing special HTML characters with their entity equivalents.

  handler: async ({ input }: { input: string }) => {
    const encoded = input
      .replace(/&/g, '&')
      .replace(/</g, '<')
      .replace(/>/g, '>')
      .replace(/"/g, '"')
      .replace(/'/g, ''');
    return {
      content: [
        {
          type: 'text',
          text: encoded
        }
      ]
    };
  }

• src/tools/encoding.ts:105-114 (schema)

  The input schema defining the expected arguments for the encodeHtml tool: a required string 'input'.

  inputSchema: {
    type: 'object',
    properties: {
      input: {
        type: 'string',
        description: 'Data to encode'
      }
    },
    required: ['input']
  },

• src/tools/encoding.ts:102-131 (registration)

  The complete definition of the encodeHtml tool, including name, description, schema, and handler, exported as part of encodingTools for registration in the main server.

  encodeHtml: {
    name: 'encodeHtml',
    description: 'Encode input data to HTML-encoded format',
    inputSchema: {
      type: 'object',
      properties: {
        input: {
          type: 'string',
          description: 'Data to encode'
        }
      },
      required: ['input']
    },
    handler: async ({ input }: { input: string }) => {
      const encoded = input
        .replace(/&/g, '&')
        .replace(/</g, '<')
        .replace(/>/g, '>')
        .replace(/"/g, '"')
        .replace(/'/g, ''');
      return {
        content: [
          {
            type: 'text',
            text: encoded
          }
        ]
      };
    }
  },
