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 company-enrich-agentdiet-dev-rag-context-sanitizer-mcp-tool-discovery-fe2b0919
```

Example prompt: Search the MCP tool index for servers that handle SEC filings or company enrichment — I need a sanitized, compressed list of what's available so I can route my next task.

## When to prefer this

Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, rather than hardcoding tool lists. Especially useful when routing tasks at runtime, verifying endpoint compliance, or needing token-compressed tool summaries to stay within context limits.

## Known failure modes

- Empty query string returns a validation error
- No matching tools found for obscure or highly specific queries
- Prompt-Guard firewall may block or sanitize inputs it flags as unsafe
- Endpoint URL verification may return compliance failures for non-conformant targets
- HTTP 402 payment required if x402 payment header is missing or malformed

## How this service works

Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://company-enrich.agentdiet.dev/v1/workflows/rag-context-sanitizer)

## Output

Returns a compressed, prompt-guard-sanitized list of matching MCP servers or A2A tools relevant to the capability query, including tool metadata and routing information. Response is a generic JSON object with discovered endpoint results.
