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 hn-pulse.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches a meta-index of 500+ MCP servers and A2A tools to discover matching capabilities, proxying calls with token compression and prompt-injection 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://hn-pulse.agentdiet.dev/v1/execute)
Output
Returns a list of matching MCP servers or A2A tool endpoints relevant to the query, with compressed capability metadata (85% token reduction), safety-filtered through the Prompt-Guard firewall, including endpoint URLs, capability summaries, and routing recommendations.
Example use cases
Discovering GitHub audit tools
“Search the tool index for anything related to 'GitHub security' or code auditing — I want to find an MCP server my agent can route to for scanning repos.”
Finding on-chain risk analysis endpoints
“Look up what A2A or MCP tools are available for on-chain risk analysis and DEX token intelligence so I can wire one into my DeFi monitoring workflow.”
Routing to email verification capability
“I need my agent to verify email addresses at scale — can you search the MCP tool index for 'email verification' and tell me which endpoints are available?”
Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to dynamically discover which MCP server or A2A agent tool can fulfill a capability at runtime, rather than hard-coding a specific endpoint. Especially useful for swarm architectures where an orchestrator needs to find the best available tool for a given task from a large index, or when you want safe proxying with token-budget optimization.
Side effects
- Empty results if query is too niche or no indexed tool matches
- Rate limiting or 402 payment required if credit balance is exhausted
- Timeout if the meta-index is temporarily unavailable
- Malformed query returns validation error
- Firewall may block results containing suspected prompt-injection patterns
