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://workflows.agentdiet.dev/v1/a2a-router)
Output
Returns a compressed (up to 85% token reduction) list of matching MCP servers or A2A tools from the 500+ tool index, filtered through the Prompt-Guard firewall, including tool metadata and routing recommendations relevant to the capability query.
Example use cases
Swarm router for agent orchestration
“I'm building a multi-agent workflow and need to find which MCP servers in your index can handle GitHub security audits — can you search for that and route me to the best options?”
Capability discovery for new integrations
“Search your 500+ tool index for any A2A agents or MCP servers that do context compression or token reduction, so I can plug one into my pipeline.”
Endpoint verification before integration
“Can you verify whether this endpoint URL is a legitimate indexed MCP server in your router before I integrate it into my agent swarm?”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability without maintaining its own tool registry. It is especially useful for swarm orchestration, meta-routing across heterogeneous agent ecosystems, or when token budget is tight and compressed discovery results are needed.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure capability queries
- Endpoint URL verification returns unknown or unindexed result
- Payment required (HTTP 402) if x402 micropayment not attached
- Index may not reflect newly added MCP servers in real time
