## 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 mcp-manifest-drift-report-49488aa3 -d '<json body>'
```

Example prompt: Generate a full drift report for my MCP server at https://my-mcp-server.example.com — I want to see everything that's changed or drifted from the expected manifest baseline.

## When to prefer this

Prefer this endpoint over the sibling 'MCP Manifest Drift Check' when you need a full, detailed drift report rather than a simple pass/fail check — ideal for audits, compliance reviews, post-deployment verification, or building a change log of MCP manifest evolution over time.

## Known failure modes

- Unreachable MCP server URL results in a connection error
- Invalid or unparseable manifest returns a parsing failure response
- No baseline provided may result in an empty or trivial diff
- Rate limiting or payment failure at $0.05 USDC per call blocks the request
- Malformed request body returns a 400 bad request error

## How this service works

Signed drift history for one MCP server: pins over time, every detected drift event, and a current verdict (stable, changed, or poisoning-suspect). $0.05 USDC per report.

## Output

Returns a structured drift report detailing all differences between the MCP server's current manifest and an expected or previous baseline — including added, removed, and modified tools, resources, prompts, or metadata fields, along with a summary of the overall drift severity.
