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://mesh.agentdiet.dev/v1/b2a-router)
Output
Returns a compressed list of matching MCP servers or A2A tools (with 85% token reduction), including capability descriptions, endpoint URLs, and prompt-injection firewall status. For URL verification, returns whether the endpoint is indexed and safe to proxy.
Example use cases
Finding tools for on-chain risk
“Search for MCP servers or A2A tools that can analyze on-chain risk or crypto wallet activity — I want a list of what's available so I can route my agent through the best one.”
Verifying an endpoint before calling it
“Before my agent calls this endpoint URL https://sometools.dev/api/v1/run, can you verify it's indexed and safe to proxy through the tool router?”
Discovering GitHub audit agents
“Find me any MCP servers or A2A tools in the index that do GitHub repository auditing, dependency scanning, or supply-chain security — I need to pick one for my coding agent workflow.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/b2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover the right tool or MCP server from a large ecosystem rather than calling a known endpoint directly. Especially useful in swarm/orchestrator architectures where the agent must dynamically select from 500+ capabilities, or when you want prompt-injection firewall protection wrapping the discovery layer. Prefer this over building your own MCP registry or calling individual tool APIs blindly.
Side effects
- Empty or too-broad query returns too many results with low relevance
- Unknown or unindexed endpoint URL returns no verification match
- Query string missing or empty returns a 400/validation error
- Downstream MCP server index temporarily unavailable causing partial results
- x402 payment failure if USDC balance or payment header is missing
