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/execute)
Output
Returns a ranked list of matching MCP servers or A2A tools with metadata, routing information, and safe-proxy access details. Includes tool capabilities, endpoint URLs, and compressed schema information with up to 85% token reduction.
Example use cases
Discover tools for GitHub security audits
“I need to find an MCP server or A2A agent that can run GitHub security audits on a repo — search the tool index for 'github security' and tell me what's available.”
Route context compression request to best tool
“Find me the best MCP tool for context compression from the 500+ server index and proxy my request through it safely.”
Locate B2B lead enrichment capability
“Search your tool discovery index for 'company enrichment' or 'B2B lead enrichment' agents — I want to know which MCP servers are available and what they can do.”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover and connect to the right MCP server or A2A tool from a large index without managing multiple connections. Particularly useful when the specific capability tool is unknown and needs to be searched, or when token budget is constrained and compression is needed, or when a prompt injection firewall is required for safe tool routing.
Side effects
- Query returns no matching tools if capability is too niche or not indexed
- Prompt injection attempt blocked by Prompt-Guard firewall with rejection notice
- Payment required error (HTTP 402) if USDC payment not attached
- Endpoint URL verification returns invalid or unreachable status
- Token compression may lose detail for highly structured schemas
