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/b2a-router)
Output
Returns a token-compressed list of matching MCP servers or A2A tool endpoints relevant to the capability query, filtered through a Prompt-Guard firewall to prevent injection attacks, with metadata about each discovered tool.
Example use cases
Swarm agent tool discovery
“I'm building a swarm of agents and need to find which MCP servers in the index can handle GitHub repository security audits — search for 'github security' and give me the top matches.”
Capability routing for research pipeline
“Find me all indexed A2A tools that support ArXiv paper search or academic research so I can plug the best one into my literature review agent.”
Verify an unknown endpoint
“I found this endpoint URL at https://some-service.dev/api/tool — can you verify it against the MCP and A2A tool index to see if it's a known, safe capability I can route to?”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/b2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover and route to specialized MCP or A2A tools at runtime rather than hardcoding integrations. Especially valuable when building agent swarms that need to self-assemble capabilities or when the right tool for a task is unknown in advance. The 85% token compression makes it efficient for agents with tight context budgets.
Side effects
- Empty or vague query returns no results or generic matches
- Unknown or unindexed endpoint URL returns no verification match
- Query too broad causes high token output even with compression
- Rate limiting or payment failure returns HTTP 402 requiring x402 micropayment
- Firewall may flag legitimate queries containing prompt-like patterns
