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/security-audit-dag)
Output
Returns a structured list of matching MCP servers and A2A tools ranked by relevance to the query, with 85% token-compressed capability descriptions, endpoint URLs, safety/firewall status from the Prompt-Guard layer, and metadata for direct routing.
Example use cases
Discover tools for on-chain risk analysis
“Search the tool index for MCP servers or A2A agents that handle on-chain risk or smart contract security — I need to route my DeFi agent to the right one.”
Find a verified MCP endpoint for email verification
“Can you look up which MCP servers in the index support email verification? I want a safe, firewall-checked connection rather than calling an unknown endpoint directly.”
Route agent swarm to context compression tools
“My agent swarm is hitting token limits — search the A2A and MCP tool registry for anything that does context compression or token reduction so I can wire it in.”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/security-audit-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover, evaluate, or route to MCP servers or A2A tools at runtime without hardcoding endpoints — especially when safety (prompt-injection firewall) and token efficiency (85% compression) matter. Prefer this over manual MCP registry browsing or direct untrusted endpoint calls.
Side effects
- Empty or too-vague query returns broad or no results
- Queried endpoint URL not in the index returns no match
- Index may not reflect newly added MCP servers in real time
- Token compression may omit nuanced capability details
- x402 payment failure results in 402 response before any lookup
