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/b2a-router)
Output
A list of matched MCP servers or A2A tools relevant to the search query, with compressed metadata (up to 85% token reduction) about each tool's capabilities, endpoint URLs, and routing details, filtered through a Prompt-Guard firewall to block injected malicious instructions.
Example use cases
Finding SEC filing tools for agent
“Search the MCP router for any tools or servers that can pull SEC filings — I need my agent to look up 10-K reports automatically.”
Discovering email verification capabilities
“Can you query the MCP tool index for 'email verification' and tell me which servers are available so I can route my lead validation workflow there?”
Routing to on-chain risk analysis tools
“I need to find MCP servers that handle on-chain risk or DEX token intelligence — search the meta-router and give me the top matches.”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/b2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool supports a given capability at runtime, rather than hardcoding tool connections. Ideal for swarm or orchestrator agents that need to find and proxy to the right sub-agent tool without maintaining a manual registry. Best when token efficiency matters and prompt injection protection is required.
Side effects
- Empty or overly vague query returns no matches or low-confidence results
- Payment not completed (HTTP 402) blocks access to results
- Query matches no indexed tools, returning empty result set
- Rate limiting or quota exhaustion returns error response
- Prompt-Guard firewall may flag and reject queries containing suspicious content
