# GENESIS Agent Tools — MCP Readiness Check (Dexter Facilitator)

> GENESIS Agent Tools — MCP Readiness Check (Dexter Facilitator) is a paid API for AI agents from genesis-agent-tools.genesisagenttools.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Checks whether an agent tool, MCP card, or instruction set is ready for use in agent/MCP environments, returning readiness scores, evidence, and warnings via quick or deep analysis.

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 genesis-agent-tools-mcp-readiness-check-dexter-facilitator-d971d9b7 -d '<json body>'
```

Example prompt: Run a deep MCP readiness check on my tool card — here's the card object and the instructions array — and tell me if there are any warnings or evidence of incompatibility before I deploy it to my agent fleet.

## When to prefer this

Choose this endpoint when you need to programmatically verify that an MCP card, tool definition, or instruction set meets agent readiness standards before deployment — especially in automated CI/CD pipelines for agent tooling, or when onboarding third-party tools into an agent fleet. Prefer the quick tier for fast pre-flight checks and the deep tier for comprehensive audits.

## Known failure modes

- Invalid tier value returns schema validation error
- Missing or malformed card/tool/instructions fields may yield empty result with warnings
- Network or payment failure (x402) prevents call from completing
- Deep tier may time out for very large instruction sets
- Unrecognized tool schema may produce low-confidence result with empty evidence

## How this service works

Pay-per-call x402 APIs for autonomous agents on Base USDC: API compatibility analysis, bounded HTTP/JSON workflows, URL evidence analysis, crypto price consensus, and agent/MCP readiness checks.

## Output

Returns a JSON object with an ok boolean, the tier used (quick or deep), a result object with readiness details, a product label ('agent-assurance'), an evidence array of supporting findings, and a warnings array listing any compatibility issues detected.
