Implementation Reference

• src/service/digest.ts:93-98 (handler)

  The inline handler function that executes the sha1 tool logic by calling DigestUtil.sha1 and returning the hash as text content.

  ({ input }) => {
    const hash = DigestUtil.sha1(input);
    return {
      content: [{ type: "text", text: hash }],
    };
  }

• src/service/digest.ts:90-92 (schema)

  The input schema for the sha1 tool, validating input as a string using Zod.

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

• src/service/digest.ts:87-98 (registration)

  Registration of the sha1 tool on the MCP server, including name, description, schema, and handler.

  server.tool(
    "sha1",
    "Calculate SHA-1 hash of a string",
    {
      input: z.string().describe("The input string to hash"),
    },
    ({ input }) => {
      const hash = DigestUtil.sha1(input);
      return {
        content: [{ type: "text", text: hash }],
      };
    }

• src/service/digest.ts:21-24 (helper)

  Helper utility function in DigestUtil class that computes the SHA-1 hash of the input string using CryptoJS.

  static sha1(input: string): string {
    const hash = CryptoJS.SHA1(input);
    return hash.toString();
  }
