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/crypto-alpha-dag)
Output
Returns a list of matched MCP servers or A2A tools relevant to the query, including metadata about each tool's capabilities, with token-compressed output and Prompt-Guard firewall applied to filter unsafe responses.
Example use cases
Discover crypto intelligence agent tools
“Search the tool meta-index for any MCP servers or A2A agents that can do DEX token intelligence or on-chain risk scoring — I want to find the best one to route my crypto research agent through.”
Find a prompt-safe proxy for swarm routing
“I'm building a multi-agent swarm and need a single connection point that indexes MCP servers with a built-in prompt injection firewall — can you search for tools that match 'context compression' or 'prompt guard'?”
Locate GitHub security audit capability
“Find me any indexed MCP server or A2A tool that can audit GitHub repositories for security issues — search the tool discovery index for 'github security' or 'code audit'.”
Technical details
Endpoint
POSThttps://token-intel.agentdiet.dev/v1/crypto-alpha-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover and route to one of hundreds of MCP servers or A2A tools without maintaining individual connections to each. It is especially useful for swarm architectures needing a single gateway, when token budget is constrained (85% compression), or when prompt injection safety is a concern. Prefer alternatives if you already know the exact MCP endpoint you need.
Side effects
- Query too vague returns no matching tools
- No indexed tools match a niche capability query
- Payment not fulfilled via x402 results in 402 response
- Prompt injection attempt blocked by Prompt-Guard firewall
- Upstream MCP server unavailable causes partial results
- Malformed query string triggers validation error
