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 agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).
Routes a natural-language capability query across 500+ indexed MCP servers and A2A tools, returning compressed, firewall-screened tool matches via a single connection

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://agentdiet.dev/v1/b2b-osint-dag)
Output
Returns a compressed (up to 85% token reduction) list of matching MCP servers or A2A tools relevant to the query, including tool metadata, capability descriptions, and Prompt-Guard firewall clearance status. Response schema is a generic object whose contents vary by matched tools.
Example use cases
Agent swarm capability bootstrapping
“I'm spinning up a new agent swarm and need to find which MCP servers in your index handle GitHub security audits and code vulnerability scanning — show me the top options with token-compressed summaries.”
Safe-proxied tool discovery for B2B enrichment
“Find me all the A2A tools in your index that do B2B lead enrichment or company data lookups, and make sure the results are firewall-screened before you send them back.”
Verify endpoint safety before use
“Before my agent calls this endpoint URL https://someservice.example.com/api/tool, can you run it through your Prompt-Guard firewall and tell me if it's safe to use?”
Technical details
Endpoint
POSThttps://agentdiet.dev/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to discover which of hundreds of MCP servers or A2A tools best fits a required capability without maintaining your own index, when you want token-efficient tool descriptions to reduce LLM context cost, or when you need firewall-screened tool routing to protect against prompt injection from untrusted external tools. Prefer this over manual MCP directory searches or direct tool probing when operating in multi-agent or swarm contexts.
Side effects
- Empty or overly broad query returns too many low-relevance results
- Query for a very niche or novel capability finds no indexed servers
- Firewall flags a legitimate tool as suspicious, blocking a valid match
- Malformed or unreachable endpoint URL fails verification silently
- Rate limiting at $0.01/call may throttle high-frequency swarm discovery loops
