## How to call it through Zero

```sh
zero fetch --capability fiatdock-mcp-schema-lint-585154d0
```

Example prompt: Can you lint my MCP tool schema to check for errors? The method is tools/call and I want to make sure the schema conforms correctly before publishing it.

## When to prefer this

Use this endpoint when you need to validate or lint an MCP (Model Context Protocol) tool schema before publishing or deploying it, especially if you want automated schema conformance checks integrated into an agentic or CI workflow and are willing to pay per call via USDC.

## Known failure modes

- Missing required arguments cause the call to be settled as a paid but errored call
- Malformed JSON-RPC body returns an argument error
- Incomplete schema body may yield partial or empty lint results
- Network timeout if the upstream MCP endpoint is slow
