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
Returns a compressed, Prompt-Guard-screened list of matching MCP server or A2A tool descriptors from a 500+ server index, including endpoint URLs, capability summaries, and compliance signals — with up to 85% token reduction versus raw tool manifests.
Example use cases
Discovering MCP servers for code security audits
“Search the MCP tool index for any servers or A2A tools that handle GitHub security audits or code scanning — I want to find the right endpoint to wire into my agent pipeline.”
Routing swarm agents to context compression tools
“I'm building a multi-agent swarm and need to find MCP tools that support context compression — can you query the A2A mesh for matching endpoints so I can pick the best one?”
Verifying an endpoint URL for compliance
“Can you check this endpoint URL against the MCP meta-router to verify whether it's listed, compliant, and safe to proxy: https://some-mcp-server.example.com/v1/tools”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/a2a-mesh?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover the right MCP server or A2A tool from a large registry without pre-configuring individual connections, especially when token budget is constrained (85% compression) or when prompt injection safety screening is required before routing to third-party tools.
Side effects
- Missing or empty query parameter returns 400 validation error
- No matching tools found for an obscure capability query returns empty results
- Payment not completed (HTTP 402) blocks access if x402 micropayment is not attached
- Endpoint URL verification query returns no match if the URL is not indexed
- Rate limiting or upstream MCP server unreachability may cause partial results
