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/broker/execute)
Output
Returns a matched list of MCP servers or A2A tools relevant to the query, with compressed tool manifests (85% token reduction), safety-verified endpoint metadata, and routing information needed to invoke the selected capability — all through a single broker connection.
Example use cases
Discover email verification agent tool
“Search through all the indexed MCP servers and A2A tools for anything that can do email verification — I want to find and safely proxy through to the right one without having to connect to each server myself.”
Route agent swarm to GitHub audit capability
“I need to find an MCP tool in your index that handles GitHub security audits — can you look it up and route my agent swarm to it through your safe proxy?”
Verify a specific endpoint before use
“Before I connect my agent to https://some-mcp-server.example.com, can you run it through your Prompt-Guard firewall and verify it's safe and legitimate?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to discover or route to one of many MCP servers or A2A tools without maintaining individual connections to each — especially valuable when you want token-compressed tool manifests, a single authenticated connection point, or built-in prompt-injection protection before delegating to an external tool. Prefer over manually curating your own MCP index or connecting directly to untrusted agent endpoints.
Side effects
- No matching tools found for the given query — returns empty result set
- Query too vague to resolve to specific tools — may return low-relevance results
- Endpoint URL verification fails if the target is unreachable or flagged by Prompt-Guard
- Payment not processed (x402 / USDC) — returns 402 with payment instructions
- Rate limit exceeded — returns 429 error
