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/b2a-router)
Output
A token-compressed (up to 85% reduction) list of matching MCP servers or A2A tools, or a proxied response from the routed tool, filtered through a Prompt-Guard firewall to block malicious content. Includes tool metadata, availability, and capability descriptions.
Example use cases
Discover tools for a coding agent
“Search across your indexed MCP servers and A2A tools to find anything that can do GitHub repo analysis or code security auditing — I want a list of available options with minimal token overhead.”
Safe-proxy swarm routing
“I have a multi-agent swarm that needs to call various tools — route their requests through your meta-router so I get firewall-filtered, token-compressed responses across whichever MCP servers handle web search and data extraction.”
Tool capability discovery
“What tools are available in your index that can handle on-chain data or blockchain queries? Give me a GET search across your 500+ MCP server directory so I can pick the right one.”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/b2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover or route across many MCP servers or A2A tools without maintaining individual connections to each — especially when token budget is tight (85% compression) or when prompt injection safety is a concern. Prefer over direct MCP server calls when the target tool is unknown and needs to be discovered first.
Side effects
- No matching tool found for the query — empty results returned
- Prompt-Guard firewall blocks request due to detected injection or unsafe content
- Upstream MCP server unavailable — proxy returns error or timeout
- Invalid or missing query parameter — schema validation error
- Payment not received or insufficient — x402 payment required response
