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://cve-intel.agentdiet.dev/v1/universal-mcp-gateway)
Output
Returns matching MCP servers and A2A tool listings relevant to the query, with responses compressed by up to 85% for token efficiency, filtered through a Prompt-Guard firewall to block injection attacks, and routed via a single connection rather than requiring separate integrations.
Example use cases
Discover tools for GitHub security audits
“I need to find MCP servers or A2A tools in the index that can audit GitHub repositories for security vulnerabilities — search for 'github security' and tell me what's available.”
Route a context compression query safely
“Find me any tools in the MCP registry that support context compression, and route my request through the safe proxy so I don't have to worry about prompt injection attacks.”
Find lead enrichment and domain OSINT tools
“Search the universal tool index for capabilities around 'B2B lead enrichment' and 'domain OSINT' — I want to see which of the 500+ indexed servers can handle those tasks.”
Technical details
Endpoint
POSThttps://cve-intel.agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to discover, evaluate, or route to any of hundreds of MCP servers or A2A tools without maintaining individual integrations. Ideal when you want a single entry point with built-in safety (prompt-injection firewall) and token efficiency (85% compression). Prefer over manually curating tool lists or calling individual MCP endpoints directly, especially when the right tool is unknown and needs to be discovered by capability description.
Side effects
- No matching tools found for the query — empty or low-confidence result set
- Query string too vague to discriminate between many indexed tools — overly broad results
- Upstream MCP server unavailable — gateway may return partial or degraded results
- Prompt-Guard firewall blocks a query that resembles an injection attempt — false positive rejection
- Payment required (HTTP 402) if x402 micropayment not included or invalid
