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://onchain-risk.agentdiet.dev/v1/universal-mcp-gateway)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with metadata including endpoint URLs, capability descriptions, and token-compressed summaries. May also return SLA or compliance status if an endpoint URL is provided for verification.
Example use cases
Discovering tools for on-chain risk
“Find me MCP servers or A2A tools in the universal gateway index that can handle on-chain smart contract risk analysis or DeFi token security checks.”
Routing swarm agents to GitHub auditing tools
“I'm building a swarm of AI agents and need to find every MCP-compatible tool indexed under 'github security' or 'dependency auditing' — can you search the meta-router for those?”
Verifying a remote MCP endpoint
“Can you verify whether this MCP endpoint URL is live and compliant by running it through the universal gateway: https://onchain-risk.agentdiet.dev/v1/some-tool”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which MCP servers or A2A tools are available for a specific capability without knowing exact endpoints in advance. It is especially useful for building swarm agent architectures, dynamically routing tasks to the right tool, or verifying whether a known MCP URL meets compliance standards. Prefer this over direct tool calls when the right downstream tool is unknown.
Side effects
- Empty or too-generic query returns low-relevance or no results
- Endpoint URL verification fails if the target is offline or non-compliant
- Prompt-Guard firewall may block queries detected as adversarial or injection attempts
- Rate limiting or payment failure (x402) if quota is exceeded
- Vague queries like 'tools' with no specificity return an overwhelming or unranked result set
