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/mcp-router)
Output
Returns a list of matching MCP servers or A2A tools from the 500+ indexed catalog, with compressed metadata (85% token reduction) describing each tool's capabilities, endpoint URLs, and relevant schema information, filtered through the Prompt-Guard firewall.
Example use cases
Discover tools for SEC filing retrieval
“Search the MCP router index for any tools that can pull SEC filings or EDGAR data — I want to route my research agent through whichever one looks most capable.”
Find a prompt injection firewall tool
“Can you search the A2A and MCP tool index for something that handles prompt firewall or prompt-guard protection? I need to route untrusted user inputs through a safety layer.”
Route agent to GitHub security auditor
“Look up 'github security audit' in the MCP router index and tell me which tools are available so I can connect my code review agent to the right one.”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/mcp-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover and route to one of many MCP servers or A2A tools without hardcoding individual connections — especially useful in swarm architectures, multi-agent orchestration, or when the required capability is unknown at build time. Prefer it over maintaining a static tool registry when the tool landscape changes frequently.
Side effects
- Empty or too-vague query returns no matches
- Query matches no tools in the current index
- Rate limit or payment failure (HTTP 402) if USDC micropayment not processed
- Timeout if upstream MCP servers are unresponsive
- Index may not reflect newly added or removed tools in real time
