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://mcp-security.agentdiet.dev/v1/a2a-mesh)
Output
A list of matching MCP servers and A2A tool endpoints relevant to the search query, with compressed metadata (85% token reduction) and prompt-injection screening applied. Each result includes tool names, capabilities, and connection details.
Example use cases
Discovering GitHub security audit tools
“Find me MCP servers or A2A tools that can audit GitHub repositories for security vulnerabilities — search your index and tell me what's available.”
Routing to context compression capability
“Which tools in your index support context compression? I want to reduce token usage in my agent pipeline and need a service I can route to.”
Finding DEX token intelligence endpoints
“Search for A2A tools that cover DEX token intelligence or on-chain risk — I need to route my crypto analysis agent to the right MCP server.”
Technical details
Endpoint
POSThttps://mcp-security.agentdiet.dev/v1/a2a-mesh?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover or route to one of hundreds of MCP/A2A tools without maintaining its own index. Ideal when you want a single connection point that screens for prompt injection and compresses results for token efficiency, rather than hardcoding tool URLs or building your own discovery layer.
Side effects
- Empty or vague query returns no useful matches
- Query too broad returns too many low-relevance results
- Endpoint URL verification fails if the target is offline
- Rate limiting or payment failure returns HTTP 402
- Prompt-Guard firewall may block queries that resemble injection attempts
