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://alpha-stream.agentdiet.dev/v1/agent-router)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with compressed metadata (up to 85% token reduction) describing each tool's capability, endpoint, and routing information. Results are filtered through a Prompt-Guard firewall to block injection risks.
Example use cases
Discovering email verification tools
“Search the agent tool index for any MCP server or A2A endpoint that does email verification — I need to find one I can call through a single proxied connection.”
Finding SEC filings capability
“Look through the 500+ indexed MCP tools and find me something that can pull SEC filings or company financial data — I want results with compressed metadata so I'm not burning tokens.”
Routing to on-chain risk analysis
“Find me an MCP server or A2A tool in the swarm that handles on-chain risk or crypto wallet analysis, and route me to it safely through the proxy.”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/agent-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP or A2A tool to call for a given capability, rather than hardcoding tool endpoints. Especially useful when building swarm agents that need to self-route across 500+ tools, when token budget is a concern (85% compression), or when you want prompt-injection protection via the Prompt-Guard firewall before delegating to a third-party tool.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or misspelled capability queries
- Upstream MCP server unavailable or returning errors at proxy time
- Rate limiting or payment failure via x402 if quota exceeded
- Malformed endpoint URL when used in URL-verification mode
