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://x402-audit.agentdiet.dev/v1/mesh/dispatch)
Output
Returns a list of matched MCP servers and A2A tools relevant to the query, with compressed tool manifests (85% token reduction), routing metadata, and Prompt-Guard firewall screening applied to prevent prompt injection from upstream tools.
Example use cases
Finding GitHub security audit tools
“Search the agent tool mesh for any MCP servers or A2A tools that can run GitHub security audits — I want to find all available options before picking one.”
Locating on-chain risk and DEX intelligence tools
“Can you query the MCP tool index for anything covering on-chain risk analysis or DEX token intelligence? I need to know what's available in the ecosystem.”
Discovering email verification capabilities
“Search across the 500+ indexed MCP servers for tools that do email verification or domain OSINT — I'm building an agent pipeline and want to know my options.”
Technical details
Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover which MCP servers or A2A tools exist for a given capability without knowing them in advance, especially when token budget is constrained (85% compression) or when prompt injection from untrusted tool responses is a concern. Prefer this over direct MCP server connections when orchestrating multi-tool swarms or when you need a single connection point into a broad ecosystem.
Side effects
- Empty query string returns validation error
- No matching tools found for niche queries
- Upstream MCP server unavailable causing partial results
- Payment not processed via x402 results in 402 response
- Malformed endpoint URL when used in verification mode
