Crypto_MCP

Instructions

Implementation Reference

• src/service/digest.ts:122-127 (handler)

  Handler function for the sha384 MCP tool. It invokes DigestUtil.sha384 on the input string and formats the result as MCP text content.

  ({ input }) => {
    const hash = DigestUtil.sha384(input);
    return {
      content: [{ type: "text", text: hash }],
    };
  }

• src/service/digest.ts:119-121 (schema)

  Input schema definition for the sha384 tool using Zod, specifying a string parameter.

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

• src/service/digest.ts:116-128 (registration)

  Registration of the sha384 tool via server.tool call within registerDigestTool function.

  server.tool(
    "sha384",
    "Calculate SHA-384 hash of a string",
    {
      input: z.string().describe("The input string to hash"),
    },
    ({ input }) => {
      const hash = DigestUtil.sha384(input);
      return {
        content: [{ type: "text", text: hash }],
      };
    }
  );

• src/service/digest.ts:41-44 (helper)

  Core implementation of SHA-384 hashing in DigestUtil class using CryptoJS library.

  static sha384(input: string): string {
    const hash = CryptoJS.SHA384(input);
    return hash.toString();
  }

• src/index.ts:16-16 (registration)

  Top-level registration call that invokes registerDigestTool on the main McpServer instance, thereby registering the sha384 tool.

  registerDigestTool(server);
