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/bundle-execute)
Output
Returns a list of matching MCP servers or A2A tools ranked by relevance to the query, with 85% token-compressed descriptions, Prompt-Guard firewall screening applied, and routing metadata for connecting to each tool.
Example use cases
Discovering tools for GitHub security audits
“Can you search the MCP tool index for anything that does GitHub security auditing or code vulnerability scanning? I want to see what's available before wiring it into my pipeline.”
Finding a safe proxy for DEX token intelligence
“Look through the A2A and MCP server index for tools that cover DEX token intelligence or on-chain risk analysis — I need something I can route through a firewall-protected proxy.”
Routing agent to context compression tool
“Search the meta-router for MCP servers that offer context compression — I want the one with the best token reduction so I can plug it into my swarm.”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/bundle-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability at runtime, rather than hardcoding tool URLs. It is especially valuable when you want token-compressed tool manifests to reduce context overhead, need a single connection point to a large tool index, or require prompt-injection firewall screening before routing to third-party tools.
Side effects
- Empty or too-broad query returns low-relevance results
- Query for a niche capability not yet indexed returns no matches
- Prompt-Guard firewall blocks queries flagged as adversarial or injection attempts
- Rate limiting or payment failure (HTTP 402) if x402 payment header is missing or insufficient
- Malformed query string returns a validation error
- Upstream MCP server index temporarily unavailable causes partial results
