Implementation Reference

• src/service/digest.ts:137-142 (handler)

  MCP tool handler for 'sha512' that invokes DigestUtil.sha512 on the input and returns the hexadecimal hash as text content.

  ({ input }) => {
    const hash = DigestUtil.sha512(input);
    return {
      content: [{ type: "text", text: hash }],
    };
  }

• src/service/digest.ts:134-136 (schema)

  Input schema for the sha512 tool using Zod: a single string parameter.

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

• src/service/digest.ts:131-143 (registration)

  Registration of the 'sha512' tool on the McpServer instance, including name, description, schema, and handler function.

  server.tool(
    "sha512",
    "Calculate SHA-512 hash of a string",
    {
      input: z.string().describe("The input string to hash"),
    },
    ({ input }) => {
      const hash = DigestUtil.sha512(input);
      return {
        content: [{ type: "text", text: hash }],
      };
    }
  );

• src/service/digest.ts:51-54 (helper)

  Utility function DigestUtil.sha512 that computes the SHA-512 hash of the input string using CryptoJS and returns the hexadecimal string.

  static sha512(input: string): string {
    const hash = CryptoJS.SHA512(input);
    return hash.toString();
  }
