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://cve-intel.agentdiet.dev/v1/tool-broker)
Output
Returns a list of matching MCP servers or A2A tool cards from a 500+ endpoint index, with token-compressed descriptions (up to 85% reduction), relevance scores, and endpoint metadata. Results pass through a Prompt-Guard firewall to block prompt injection. Response schema is an open object containing matched tools and their capabilities.
Example use cases
Finding tools for GitHub security audits
“Search the tool broker for MCP servers or A2A agents that can do GitHub security audits or code vulnerability scanning — I want to wire the best one into my CI pipeline agent.”
Routing agent to context compression tools
“Can you query the tool discovery index for any MCP servers that specialize in context compression or token reduction? I need to cut down my agent's prompt size.”
Discovering DeFi data endpoints for swarm
“Search for available A2A tools or MCP servers that handle DeFi liquidity data or on-chain risk analysis so I can plug the right one into my trading swarm.”
Technical details
Endpoint
POSThttps://cve-intel.agentdiet.dev/v1/tool-broker?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 for a given capability, rather than hard-coding a specific tool. It is the right choice when building agent orchestrators, swarm routers, or meta-agents that must select tools at runtime. Prefer this over manually curating tool lists when the capability space is large or frequently changing.
Side effects
- Empty query string returns validation error (minLength:1 violated)
- No matching tools found for obscure capability queries returns empty result set
- Prompt-Guard firewall may suppress results flagged as injection attempts
- x402 payment failure if insufficient USDC balance on Base
- Rate limiting or 402 payment required if per-call fee not settled
