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://github-audit.agentdiet.dev/v1/tool-broker)
Output
Returns a compressed list of matching MCP server or A2A tool entries from the 500+ tool index, including capability descriptors, endpoint URLs, compliance status, and token-compressed metadata. If an endpoint URL is provided, returns a verification result indicating schema compliance and safety status.
Example use cases
Discovering tools for GitHub security audits
“Search the MCP index for any tools that can audit GitHub repositories for security vulnerabilities — I need to pick the best one to plug into my agent pipeline.”
Verifying a third-party agent endpoint before use
“Can you check whether this endpoint URL I found — https://some-agent-tool.example.com/api — is actually a compliant MCP or A2A server before I connect my agent to it?”
Finding on-chain risk and DEX intelligence tools
“I'm building a DeFi monitoring agent and need to find MCP servers in the index that cover on-chain risk analysis and DEX token intelligence — what's available?”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/v1/tool-broker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to use for a given capability, rather than hard-coding a specific tool. Also prefer this when you want to verify a third-party agent endpoint for compliance and prompt-injection safety before routing live traffic to it. It is especially useful for swarm orchestration scenarios where the correct downstream tool is not known at build time.
Side effects
- Empty query string returns validation error (minLength:1 required)
- No matching tools found for obscure or overly narrow query
- Upstream MCP server index temporarily unavailable (503)
- Endpoint URL verification fails if target is offline or non-compliant
- HTTP 402 payment required if x402 credits are not pre-funded
