Implementation Reference

• src/service/digest.ts:79-84 (handler)

  The md5 tool handler that computes the MD5 hash of the input string using the DigestUtil helper and returns it as text content.

  ({ input }) => {
    const hash = DigestUtil.md5(input);
    return {
      content: [{ type: "text", text: hash }],
    };
  }

• src/service/digest.ts:76-78 (schema)

  Zod schema defining the input as a string for the md5 tool.

  {
    input: z.string().describe("The input string to hash"),
  },

• src/service/digest.ts:73-85 (registration)

  Registration of the md5 tool on the McpServer.

  server.tool(
    "md5",
    "Calculate MD5 hash of a string",
    {
      input: z.string().describe("The input string to hash"),
    },
    ({ input }) => {
      const hash = DigestUtil.md5(input);
      return {
        content: [{ type: "text", text: hash }],
      };
    }
  );

• src/service/digest.ts:11-14 (helper)

  DigestUtil.md5 static method that performs the actual MD5 hashing using CryptoJS.

  static md5(input: string): string {
    const hash = CryptoJS.MD5(input);
    return hash.toString();
  }
