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://email-verify.agentdiet.dev/v1/agent-router)
Output
Returns a structured list of matched MCP servers and A2A tools relevant to the search query, with compressed metadata (85% token reduction) about each tool's capabilities, endpoint URLs, and routing information, filtered through a Prompt-Guard firewall.
Example use cases
Finding a GitHub security audit tool
“Search the MCP tool index for any servers that handle GitHub security auditing — use the query 'github security audit'.”
Discovering company enrichment agents
“I need to find a tool that can do B2B company enrichment — search the meta-router with 'company enrichment' and tell me what's available.”
Locating context compression capability
“Look up what MCP servers are available for context compression — query the agent router with 'context compression' and show me the top matches.”
Technical details
Endpoint
POSThttps://email-verify.agentdiet.dev/v1/agent-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool can handle a specific capability, rather than hardcoding tool endpoints. Ideal for swarm orchestration, multi-agent pipelines, or when building an agent that must self-assemble its toolset at runtime across 500+ indexed services.
Side effects
- Empty or overly vague query returns no matches or low-relevance results
- Query that matches no indexed servers returns empty results object
- Malicious prompt injection in query blocked by Prompt-Guard firewall with rejection response
- Payment required (HTTP 402) if x402 micropayment not included
- Invalid idempotency key format may cause request rejection
