## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentdiet-mcp-validator-schema-compiler-20f06f4a
```

Example prompt: Can you audit my MCP server at https://myserver.example.com using the Glama TDQS rubric and compile a drop-in A2A Agent Card and x402 config for it?

## When to prefer this

Choose this endpoint when you need to validate an MCP server against the Glama TDQS quality rubric and automatically generate production-ready A2A Agent Cards and x402/MPP configs — especially before publishing an MCP tool to a marketplace or integrating it into an agent workflow. Prefer this over generic linters or schema validators when you need Glama-specific scoring and multi-protocol output (A2A + x402) in one call.

## Known failure modes

- Unreachable or invalid target URL returns an error with no audit data
- Private GitHub repo without access credentials cannot be fetched
- Malformed target parameter causes schema validation rejection
- Target server is not an MCP-compatible endpoint, producing empty or partial results
- Rate limit or payment failure at $0.01 USDC per call
