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://x402broker.com/v1/universal-mcp-gateway)
Output
Returns a list of matching MCP servers or A2A tools from a 500+ item index, including capability descriptions, endpoint metadata, token compression ratios, and safety/firewall status — all compressed to approximately 15% of raw token cost.
Example use cases
Agent tool discovery for code security
“Find me all the MCP servers and A2A tools indexed in the universal gateway that can do GitHub security auditing or dependency vulnerability scanning.”
Capability routing for SEC data
“I need to find which tools in your MCP index can pull SEC filings — search for 'SEC filings' and show me what's available with the best token efficiency.”
Prompt-safe proxy verification
“Check the universal MCP gateway to see if the endpoint https://some-tool.example.com/api is indexed and verified as safe to proxy through your Prompt-Guard firewall.”
Technical details
Endpoint
GEThttps://x402broker.com/v1/universal-mcp-gateway?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to discover, route to, or verify MCP servers and A2A tools from a large aggregated index, especially when token budget is a concern (85% compression) or when safety from prompt injection in third-party tools is required. Prefer this over manually maintaining a list of tool endpoints or calling individual registries separately.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure capability queries returns empty result set
- Unindexed or unknown endpoint URL returns not-found status
- Rate limiting or payment failure (x402) blocks access
- Prompt injection attempts detected by Prompt-Guard firewall may return filtered/rejected response
