Implementation Reference

  • Registration and handler implementation for the hex_encode MCP tool.
    server.tool(
      "hex_encode",
      "Encode a string to its hexadecimal representation.",
      { input: z.string().describe("The string to hex-encode") },
      async ({ input }) => ({
        content: [
          {
            type: "text" as const,
            text: Buffer.from(input, "utf-8").toString("hex"),
          },
        ],
      })
    );
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. Discloses basic transformation but lacks critical output format details: uppercase vs lowercase hex, 0x prefix behavior, character encoding assumptions (UTF-8), and handling of empty/null inputs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence of seven words with zero redundancy. Purpose is front-loaded and immediately scannable. Appropriate length for the tool's simplicity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Sufficient for a single-parameter transformation tool with complete schema coverage, though output characteristics (hex string format) should be specified since no output schema exists. Acceptable but minimal.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with clear parameter description. Tool description mentions 'string' which aligns with schema but adds no additional semantic constraints (e.g., encoding requirements, max length, binary vs text handling). Baseline 3 appropriate given schema completeness.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States clear verb 'encode' and resource 'string' with target format 'hexadecimal'. Implicitly distinguishes from sibling hex_decode by directionality (string-to-hex vs hex-to-string), though explicit sibling differentiation would strengthen it further.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides no guidance on when to select this tool over alternatives like base64_encode, url_encode, or generate_random_hex. No prerequisites, error conditions, or selection criteria mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
