Implementation Reference

• src/tools/encoding.ts:15-25 (handler)

  The asynchronous handler function that encodes the input string to Base64 using Node.js Buffer API and returns the result in the standard MCP tool response format.

  handler: async ({ input }: { input: string }) => {
    const encoded = Buffer.from(input).toString('base64');
    return {
      content: [
        {
          type: 'text',
          text: encoded
        }
      ]
    };
  }

• src/tools/encoding.ts:5-14 (schema)

  Defines the input schema for the encodeBase64 tool, requiring an object with a single 'input' property of type string.

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

• src/index.ts:27-33 (registration)

  Registers encodeBase64 (via encodingTools) into the allTools collection, which is used by the MCP server's ListTools and CallTool request handlers to expose and execute the tool.

  const allTools: ToolKit = {
    ...encodingTools,
    ...geoTools,
    ...generatorTools,
    ...dateTimeTools,
    ...securityTools
  };
