demo_security_snapshot

Test security header audits with a free example snapshot to verify integration or demonstrate output format before live scans.

Instructions

Returns a pre-baked example security snapshot (no payment required). Use this to test your integration or demonstrate the output format without spending USDC.

Implementation Reference

  • The handler logic for 'demo_security_snapshot' which fetches a JSON response from the API's demo endpoint.
    if (name === "demo_security_snapshot") {
      const res = await fetch(`${BASE_URL}/demo/snapshot`);
      if (!res.ok) {
        throw new McpError(ErrorCode.InternalError, `Demo endpoint returned ${res.status}`);
      }
      const data = await res.json();
      return {
        content: [{ type: "text", text: JSON.stringify(data, null, 2) }],
      };
    }
  • src/index.ts:82-92 (registration)
    The registration block for the 'demo_security_snapshot' tool.

Behavior4/5

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

With no annotations provided, the description carries the full burden and does well by disclosing key behavioral traits: it returns a pre-baked example (not real-time data), requires no payment (financial aspect), and is for testing/demonstration purposes. It lacks details on rate limits or authentication needs, but covers core functionality adequately.

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?

The description is front-loaded with the core purpose in the first sentence and adds essential context in the second, with zero wasted words. Every sentence earns its place by providing critical information without fluff.

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

Completeness4/5

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

Given the tool's low complexity (0 parameters, no output schema), the description is nearly complete: it explains the purpose, usage context, and key behavioral aspects. It could slightly improve by mentioning the output format details or any constraints, but it's sufficient for an agent to use it correctly in most scenarios.

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

Parameters4/5

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

The input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description appropriately does not discuss parameters, and the baseline for this case is 4, as it efficiently avoids redundancy while the schema handles the structure.

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

Purpose5/5

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

The description clearly states the tool's purpose with specific verbs ('Returns a pre-baked example security snapshot') and resources ('security snapshot'), and distinguishes it from its sibling by explicitly noting it's for testing/demonstration without payment versus the likely production-oriented 'scan_security_headers'.

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

Usage Guidelines5/5

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

It provides explicit guidance on when to use this tool ('to test your integration or demonstrate the output format without spending USDC'), which implicitly suggests alternatives like the sibling tool for actual scans requiring payment, making it clear for agent selection.

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