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://shopify-intel.agentdiet.dev/v1/universal-mcp-gateway)
Output
Returns a compressed list of matching MCP servers and A2A tool endpoints relevant to the query, including capability descriptors, routing metadata, and prompt-firewall-screened summaries. Results are token-compressed by approximately 85% to minimize context usage.
Example use cases
Agent swarm tool discovery
“Search across all indexed MCP servers for anything that does on-chain risk scoring or DEX token intelligence — I'm building a DeFi agent swarm and need to know what's available.”
Capability routing for GitHub audits
“Find me an MCP tool in the index that can do GitHub security audits — I want to plug it into my agent pipeline for automated code review.”
Single-connection proxy for email verification
“I want to route my agent to an email verification tool without managing dozens of MCP connections — can you search the meta-router index for email verification capability?”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to delegate a subtask to, rather than hardcoding a specific tool. Ideal for swarm architectures, multi-tool orchestration, or when the required capability is unknown at design time. Prefer it over direct MCP connections when token efficiency matters and when prompt-injection protection is required across untrusted tool outputs.
Side effects
- Empty query string returns validation error
- No matching tools found for niche query returns empty result set
- Unrecognized endpoint URL passed as query may return no verification result
- Downstream MCP server unavailability may result in partial index results
- Payment not completed (HTTP 402) blocks access entirely
