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 onchain-risk.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).
Searches a meta-index of 500+ MCP servers and A2A tools by capability query, returning matching endpoints with token-compressed results and prompt-injection firewall protection

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/mcp-gateway)
Output
A list of matching MCP servers or A2A tools from the 500+ endpoint index, with token-compressed capability descriptions and metadata, filtered through the Prompt-Guard firewall to remove any injected malicious instructions.
Example use cases
Discover SEC filing tools for agent
“Find me MCP servers in your index that can retrieve SEC filings — I want to know which tools are available and what capabilities they expose.”
Find prompt firewall endpoints
“Search the meta-router for any A2A or MCP tools that handle prompt injection detection or jailbreak firewall capabilities.”
Locate DEX token intelligence tools
“I need to find tools for DEX token intelligence and on-chain risk analysis — can you search the MCP gateway index and tell me what's available?”
Technical details
Endpoint
POSThttps://onchain-risk.agentdiet.dev/v1/mcp-gateway?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability, rather than hard-coding tool URLs. Ideal for swarm architectures where agents need to self-assemble toolchains at runtime. Prefer over manual MCP server lists when the tool landscape is large (500+), when token budget is a concern (85% compression), or when untrusted third-party tool responses need prompt-injection screening.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or misspelled capability query
- Endpoint URL verification fails if the target is offline or non-compliant
- Rate limiting or payment failure if x402 microtransaction is rejected
- Timeout if meta-router cannot reach indexed MCP servers in time
