Implementation Reference
- src/tools/encoding.ts:40-50 (handler)The handler function that executes the decodeBase64 tool logic, decoding the input string from base64 using Node.js Buffer and returning it as text content.handler: async ({ input }: { input: string }) => { const decoded = Buffer.from(input, 'base64').toString('utf-8'); return { content: [ { type: 'text', text: decoded } ] }; }
- src/tools/encoding.ts:30-39 (schema)The input schema defining the expected arguments for the decodeBase64 tool: an object with a required 'input' string.inputSchema: { type: 'object', properties: { input: { type: 'string', description: 'Data to decode' } }, required: ['input'] },
- src/index.ts:27-33 (registration)Registers the decodeBase64 tool (via encodingTools) by including it in the allTools collection used by the MCP server's listTools and callTool request handlers.const allTools: ToolKit = { ...encodingTools, ...geoTools, ...generatorTools, ...dateTimeTools, ...securityTools };
