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://github-audit.agentdiet.dev/v1/universal-mcp-gateway)
Output
Returns matched MCP servers or A2A tools relevant to the query, with token-compressed results and firewall-filtered responses, including routing metadata and tool capability descriptions.
Example use cases
Discovering a GitHub security audit tool
“I need to find an MCP tool that can audit GitHub repositories for security issues — search your index of 500+ servers and tell me what's available.”
Routing to an SEC filings capability
“Can you search your MCP gateway for any tool that handles SEC EDGAR filings or 10-K financial data, and route my query through it?”
Finding a domain OSINT capability
“Look through your connected MCP servers for something that does domain OSINT or WHOIS intelligence — I want to run a query against a suspicious domain.”
Technical details
Endpoint
POSThttps://github-audit.agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover the right tool or MCP server from a large index without hardcoding individual service URLs, especially when token budget is constrained (85% compression) or when prompt injection protection is required for untrusted inputs.
Side effects
- No matching tool found for the query — returns empty or low-confidence match set
- Prompt-Guard firewall blocks query if it contains potentially unsafe or injection-like content
- Payment required error (HTTP 402) if x402 credentials are missing or insufficient
- Query too short or vague — minLength:1 enforced but vague queries may return poor matches
- Downstream MCP server unavailable — gateway may return partial or degraded results
