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://shopify-spy.agentdiet.dev/v1/b2a-router)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with routing metadata, capability descriptions, and optionally a compressed proxied response from the matched tool, all filtered through a Prompt-Guard firewall.
Example use cases
Finding an MCP server for GitHub audits
“I need to find an MCP server that can do GitHub security audits — search the tool index and tell me what's available.”
Routing agent query to context compression tool
“Search the A2A tool index for anything that does context compression or token budget management, and proxy my request through it.”
Discovering on-chain risk analysis tools
“Can you look up what MCP tools are available for on-chain risk analysis or DEX token intelligence and give me the top matches?”
Technical details
Endpoint
POSThttps://shopify-spy.agentdiet.dev/v1/b2a-router?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call without hardcoding individual tool URLs, especially when building swarm agents that must route across many tools, when token budget is constrained and 85% compression is needed, or when untrusted tool responses must pass through a prompt-injection firewall before being consumed.
Side effects
- Empty or vague query returns low-confidence or no tool matches
- Queried capability not yet indexed among the 500+ servers returns empty results
- Endpoint URL verification for an unknown tool returns unverifiable status
- Prompt-Guard firewall blocks a matched tool response flagged as injection risk
- Payment failure via x402 prevents call execution
