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://token-intel.agentdiet.dev/v1/a2a-router)
Output
A list of matching MCP servers or A2A tools ranked by relevance to the query, with endpoint metadata, capability descriptions, and compressed payloads filtered through a Prompt-Guard firewall to prevent injection attacks.
Example use cases
Finding tools for context compression
“Search across all indexed MCP servers and A2A tools to find anything that does context compression or token reduction — I'm trying to cut down LLM costs in my pipeline.”
Discovering GitHub audit agents
“Can you look up which MCP servers or A2A agents in the index are capable of GitHub security auditing or code scanning? I need to wire one into my CI workflow.”
Routing agent to enrichment capability
“I need to find an available tool in the MCP index that does B2B lead or company enrichment — search for it and tell me what's there so my swarm can connect to it.”
Technical details
Endpoint
POSThttps://token-intel.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools are capable of handling a specific task, rather than hard-coding tool connections. Especially valuable for swarm architectures where agents need to self-route, or when you want a single secure proxy with token compression instead of managing 500+ individual connections. Prefer this over direct MCP server calls when prompt injection protection is required.
Side effects
- Query too vague — returns empty or irrelevant matches
- No matching servers found for niche capability
- Prompt injection attempt blocked by firewall, returns rejection
- Payment not processed (x402) — request not fulfilled
- Malformed query string — validation error returned
- Upstream MCP server unavailable — partial results returned
