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://email-verify.agentdiet.dev/v1/tool-broker)
Output
Returns a list of matching MCP servers and A2A tools from the 500+ indexed catalog, with metadata about each tool's capabilities, likely compressed by up to 85% for token efficiency, and filtered through the Prompt-Guard firewall for safety.
Example use cases
Discovering GitHub audit tools for an agent
“Search through the tool broker index and find me any MCP servers or A2A tools that handle GitHub security audits — I need to know what's available before building my agent pipeline.”
Finding prompt firewall or safety tools
“Can you query the tool broker for MCP servers that offer prompt injection protection or a prompt guard firewall? I want to add a safety layer to my AI agent swarm.”
Locating B2B lead enrichment capabilities
“Use the tool broker to search for any available A2A or MCP tools that do B2B lead enrichment or company data lookups — I need to find something I can route my agent requests through.”
Technical details
Endpoint
POSThttps://email-verify.agentdiet.dev/v1/tool-broker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or route to one of many MCP servers or A2A tools without maintaining individual connections to each. Ideal for agent orchestration layers, swarm routers, or any workflow that needs to dynamically find the right sub-tool at runtime rather than hardcoding a specific API.
Side effects
- Query too vague — returns no matching tools or low-relevance results
- Payment failure via x402 — returns HTTP 402 if USDC payment not accepted
- Invalid or empty query string — returns validation error
- Upstream MCP server unavailable — routing failure for specific tool
- Rate limiting or quota exceeded — returns error if too many requests in short window
