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/a2a-router)
Output
Returns a list of matched MCP servers or A2A tools relevant to the query, with compressed tool descriptions (up to 85% token reduction), safety-filtered responses via Prompt-Guard firewall, and routing metadata including endpoint URLs and capability summaries.
Example use cases
Swarm agent tool discovery
“My agent swarm needs to find the right MCP server for doing B2B lead enrichment — can you search the index of 500+ tools and tell me what's available, with compressed results so I don't blow my token budget?”
Safe proxy for untrusted MCP calls
“I want to call an external MCP server for GitHub security audits, but route it through your prompt-injection firewall so any malicious payloads get blocked before they reach my agent.”
Capability search for DEX token intelligence
“Find me an A2A tool or MCP server in your index that handles DEX token intelligence or on-chain risk analysis — return the best match with its endpoint details.”
Technical details
Endpoint
POSThttps://whale-momentum.agentdiet.dev/v1/a2a-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 given task, especially when operating in a multi-tool swarm environment with token budget constraints. It is ideal when you want a single connection point to 500+ tools rather than maintaining individual integrations, and when prompt-injection safety on external tool responses is a priority.
Side effects
- Query returns no matching tools if the capability is too niche or not indexed
- Token compression may lose nuance for highly detailed tool descriptions
- Prompt-Guard firewall may block legitimate but ambiguous payloads
- Endpoint unavailable if upstream MCP servers are offline
- Missing or malformed query field returns validation error
