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://whale-momentum.agentdiet.dev/v1/b2a-router)
Output
Returns a token-compressed list of matching MCP servers or A2A tools relevant to the capability query, including routing metadata, endpoint references, and safety-filtered results from the Prompt-Guard firewall.
Example use cases
Discovering SEC filing tools for agent
“Search the A2A and MCP tool index for 'SEC filings' — I need to find which available tools my agent can call to pull public company financial disclosures.”
Finding on-chain risk analysis tools
“Can you search the MCP tool registry for 'on-chain risk' and tell me which servers or A2A endpoints cover DeFi wallet screening and blockchain risk scoring?”
Routing to email verification capability
“Look up 'email verification' in the MCP and A2A tool discovery index so my agent can find a safe, proxied endpoint to validate leads before outreach.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/b2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single connection point to discover, compare, and route to any of 500+ MCP servers or A2A tools without manually cataloging integrations; especially useful when token budget is constrained (85% compression) or when you need prompt injection protection via the built-in Prompt-Guard firewall.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or overly narrow queries
- Endpoint URL verification returns non-compliant status if the target is offline
- Token-compressed responses may lose nuance for very broad queries
- HTTP 402 payment required if USDC balance is insufficient
