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://polymarket-odds.agentdiet.dev/v1/a2a-router)
Output
Returns a compressed, Prompt-Guard-filtered list of matching MCP servers or A2A tools relevant to the query, including metadata about each tool's capabilities, endpoint URLs, and routing information. Response reflects 85% token compression over raw index data.
Example use cases
Discover tools for lead enrichment
“I need to find MCP servers or A2A tools that can handle B2B lead enrichment — search the index for 'company enrichment' and tell me what's available.”
Route swarm to compression tool
“My agent swarm needs context compression to cut token usage — search for 'context compression' in the tool index and show me which MCP endpoints support it.”
Verify a specific agent endpoint
“Can you check whether this URL is a compliant A2A or MCP endpoint and tell me what it does: https://some-agent.example.com/v1/tool”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover the right MCP server or A2A tool from a large index without maintaining individual connections to hundreds of servers. Ideal for swarm orchestration, dynamic tool routing, or when you want a single firewall-protected proxy layer with token-compressed responses rather than querying each tool registry separately.
Side effects
- Empty query string returns validation error (query minLength:1)
- No matching tools found for obscure or misspelled capability queries
- Endpoint URL verification may return non-compliant status for invalid URLs
- Payment required (HTTP 402) if x402 USDC micropayment is not supplied
- Index may lag behind real-time availability of newly registered MCP servers
