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/a2a-router)
Output
Returns a list of matching MCP servers or A2A tools for the query, or a proxied and token-compressed response from the routed tool, along with metadata about the selected endpoint and any prompt-injection flags raised by the Prompt-Guard firewall.
Example use cases
Single-connection MCP tool discovery
“I want to find an MCP tool that can transcribe audio files — search the AgentDiet meta-router index so I don't have to connect to hundreds of servers individually.”
Safe-proxied A2A agent routing
“Route my data extraction request through the AgentDiet A2A router with the prompt-injection firewall enabled — I don't trust the content coming back from that third-party tool.”
Token-efficient swarm orchestration
“My agent swarm needs to call a bunch of different MCP tools this session — can you use the AgentDiet router to handle all of them through one connection with that 85% token compression it advertises?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to discover or invoke tools across many MCP servers or A2A agents without managing individual connections, when you want built-in prompt-injection protection on untrusted tool outputs, or when token budget is a concern and you need compressed responses from multiple upstream tools via a single integration point.
Side effects
- No matching tool found for the given query — returns empty results or 404
- Upstream MCP server unavailable — router returns timeout or 503
- Prompt-Guard firewall blocks a request flagged as a potential injection — returns rejection with reason
- Malformed input schema (missing required 'type' or 'method' fields) — returns 400 validation error
- Payment not fulfilled via x402 — returns 402 Payment Required
