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/universal-mcp-gateway)
Output
A filtered list of matching MCP servers or A2A tools from the 500+ item index, with relevant endpoint metadata and token-compressed responses passed through the Prompt-Guard firewall to prevent prompt injection.
Example use cases
Discovering tools for GitHub security audits
“I need to find an MCP server or A2A tool that can run GitHub security audits — search the gateway index for anything matching 'github security' and tell me what's available.”
Routing an agent to context compression tools
“Can you search the universal tool gateway for MCP servers that support context compression? I want to reduce token usage in my agent pipeline.”
Finding domain OSINT capabilities for an agent
“Search the MCP tool index for anything related to domain OSINT or TLS certificate recon — I need to wire up my agent with the right server for that capability.”
Technical details
Endpoint
POSThttps://polymarket-odds.agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover and route to one of hundreds of MCP or A2A tools without maintaining individual connections to each, especially when prompt-injection safety and token efficiency are priorities. It is ideal for swarm architectures or meta-agents that need to delegate subtasks to specialized tools at runtime.
Side effects
- Empty query string returns validation error
- No matching tools found for niche or misspelled query
- Prompt-Guard firewall blocks potentially injected content in tool responses
- Upstream MCP server unreachable causing partial results
- Payment failure via x402 if USDC balance is insufficient
