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/broker/execute)
Output
Returns matching MCP server or A2A tool metadata from the 500+ indexed registry, including routing information, capability descriptions, and optionally compressed context via the 85% token reduction pipeline, filtered through the Prompt-Guard firewall.
Example use cases
Discover tools for SEC filing analysis
“Search the tool registry for any MCP servers or A2A agents that can pull or analyze SEC filings — I need to find what's available before building my research pipeline.”
Find a GitHub security audit tool
“Can you query the tool discovery index for anything that handles GitHub security audits or code vulnerability scanning? I want to route my agent swarm to the right tool.”
Route agent to company enrichment capability
“Look up available tools in the MCP registry for B2B lead enrichment or company data enrichment — I need to find and proxy through the best one for my sales automation workflow.”
Technical details
Endpoint
POSThttps://polymarket-odds.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a specific tool. Ideal for swarm orchestration, multi-agent pipelines, or when building systems that need to route tasks to the best available tool across a large, diverse registry. The built-in Prompt-Guard firewall and token compression make it preferable over raw tool directories when safety and efficiency matter.
Side effects
- Empty or too-generic query returns no relevant tools
- Queried URL endpoint not found in registry
- Query blocked by Prompt-Guard firewall due to detected injection
- Service unavailable if indexed MCP servers are offline
- Payment not completed via x402 results in 402 response
