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/x402-broker)
Output
A compressed, token-efficient list of matching MCP servers and A2A tools, with metadata about each tool's capabilities, plus Prompt-Guard firewall verification status for safety-checked endpoints
Example use cases
Discovering tools for on-chain risk
“Search the MCP tool index for anything that handles on-chain risk or DEX token intelligence — I want a compressed list of what's available so I can pick the right one.”
Verifying a suspected endpoint
“Can you check whether https://some-mcp-server.example.com/api is a legitimate, firewall-verified MCP endpoint I can safely route to?”
Finding prompt firewall MCP servers
“I need to find MCP servers that specifically offer prompt injection detection or jailbreak protection — search the tool index and give me the best matches.”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/x402-broker?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool supports a given capability across a broad index of 500+ options, rather than hardcoding tool URLs. Especially valuable when you need token-efficient results and built-in prompt-injection safety screening before routing to an external tool.
Side effects
- Empty query string returns 400 validation error
- No matching tools found for obscure capability queries
- Endpoint URL verification may return inconclusive results for private or unlisted servers
- Token compression may drop low-relevance metadata fields
- Payment failure (x402) if USDC balance is insufficient — returns HTTP 402
