Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router
Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router is a paid API for AI agents from cve-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-28).
Searches and routes across 500+ MCP servers and A2A tools via a single meta-router endpoint with token compression and prompt injection firewall

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/mcp-gateway)
Output
Returns a JSON object listing matching MCP servers or A2A tools relevant to the query, including endpoint metadata, capability descriptions, and proxied responses — all with 85% token compression applied and prompt injection filtering via the built-in Prompt-Guard firewall.
Example use cases
Discovering GitHub security audit tools
“Can you search the MCP tool index for anything that handles GitHub security auditing or code vulnerability scanning? I want to find the best available tool and proxy the call safely.”
Finding context compression agents
“Look up what MCP servers are available for context compression — I need to reduce token usage in my agent pipeline and want to see what tools are indexed for that.”
Routing to a verified A2A endpoint
“I have an endpoint URL I want to verify and route through the safe proxy — can you check if it's in the indexed registry and run my query through the Prompt-Guard firewall?”
Technical details
Endpoint
POSThttps://cve-intel.agentdiet.dev/v1/mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover and route to any of 500+ MCP servers or A2A tools from a single connection, especially when token efficiency is critical, prompt injection safety is required, or you want to avoid managing multiple individual tool connections. Prefer over direct tool calls when building swarm architectures or when you don't know which specific tool to use and need capability-based search.
Side effects
- Query too vague — returns empty or low-relevance tool matches
- Endpoint URL not found in index — verification returns no results
- Prompt-Guard firewall blocks a query flagged as potentially adversarial
- Payment required error (HTTP 402) if x402 USDC micropayment not included
- Malformed query (minLength violation) returns validation error
- Downstream MCP server unavailable during proxy routing
