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://mesh.agentdiet.dev/v1/execute)
Output
Returns a compressed (up to 85% token reduction), Prompt-Guard-firewall-screened list of matching MCP server endpoints or A2A tools relevant to the query, including capability metadata and verified endpoint URLs.
Example use cases
Agent pipeline tool discovery
“I'm building an agent that needs to pull live CVE vulnerability data — can you search the MCP tool index for anything that covers package security or OSV vulnerability scanning?”
Verify a known endpoint exists
“Check whether the endpoint https://mesh.agentdiet.dev/v1/execute is listed and verified in the A2A and MCP tool registry before I wire it into my swarm.”
Discover DeFi intelligence tools
“Search the indexed MCP servers for any tools related to DEX trading, Polymarket alpha, or on-chain token intelligence that my trading bot can call.”
Technical details
Endpoint
POSThttps://mesh.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover, verify, or route to one of 500+ MCP servers or A2A tools without managing multiple separate connections — especially when token budget is tight (85% compression) or when untrusted tool responses need firewall screening before passing back to an LLM.
Side effects
- Query string too vague returns zero or low-relevance matches
- Endpoint URL verification fails if the URL is not indexed
- Payment failure (x402) blocks execution if USDC balance is insufficient
- Idempotency-Key collision returns cached result from a prior call
- Firewall rejects a malicious or injection-containing query payload
