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/x402-gateway)
Output
A JSON response listing matched MCP servers or A2A tools relevant to the query, with capability metadata and token-compressed descriptions, filtered through the Prompt-Guard firewall.
Example use cases
Finding a compression-capable MCP server
“Search the tool index for anything that does context compression or token reduction — I'm trying to reduce how much my agent spends on each call.”
Routing agent to GitHub audit tools
“Can you look up which MCP servers or A2A tools are available for GitHub security audits? I want my agent to automatically pick the right one.”
Discovering company enrichment endpoints
“Search for available agent tools that support B2B lead enrichment or company data lookups — I need to find what's indexed and accessible through a single connection.”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/x402-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover and route to the right tool from a large catalog without maintaining individual connections to hundreds of MCP servers; especially useful for multi-agent swarms that need safe, token-efficient access to diverse capabilities through a single integration point.
Side effects
- Empty or too-broad query returns low-relevance or no matches
- Query string missing (required field) results in validation error
- No matching tools found for a highly specific or niche capability query
- Upstream MCP server unavailable causing partial result set
- Payment not processed via x402 resulting in 402 response blocking access
