# MCP Discovery Repair Plan

> MCP Discovery Repair Plan is a paid API for AI agents from agentreadiness.halowerk.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-14).

Fetches public evidence from a target URL and evaluates its MCP (Model Context Protocol) discoverability, returning a verdict, evidence source, limitations, and a concrete repair action.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-discovery-repair-plan-56947648 -d '<json body>'
```

Example prompt: Can you check if https://mycompany.com is properly set up for MCP discovery and give me a specific repair plan if anything is broken?

## When to prefer this

Use this endpoint when you need a passive, read-only MCP discoverability assessment with a concrete repair recommendation for a specific public URL. It is especially valuable when you want actionable next steps rather than just a raw audit score. Prefer it over generic site auditors when the goal is specifically MCP/agent-readiness compliance. If you need to track changes over time, supply a baseline from a previous call.

## Known failure modes

- Target URL is unreachable or returns non-200 status — check returns an error or inconclusive verdict
- Target uses authentication walls preventing passive evidence gathering — limitations field notes inaccessibility
- Malformed or too-short target URL (under 3 characters) — schema validation error returned
- Rate limiting or firewall on the target side may cause incomplete evidence — noted in limitations
- Compare URL is provided but inaccessible — comparison portion of report may be empty or flagged

## How this service works

MCP discovery repair plan fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.

## Output

Returns a structured report including: the observation made about the target's MCP discovery setup, the threshold criterion being evaluated, a pass/fail/warn verdict, the exact public evidence source used, known limitations of the passive check, and a specific mode-driven repair action the site owner can take to improve MCP discoverability.
