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/web-rag-shield-dag)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with compressed metadata about each tool's capabilities, along with safety/firewall status and routing information. Response is token-compressed by up to 85%.
Example use cases
Discover tools for SEC filing retrieval
“Find me any MCP servers or A2A tools in the index that handle SEC filings or financial document retrieval — I need to route my agent to the right one.”
Route agent query to compression-capable tool
“Search the tool registry for anything that supports token or context compression so my agent swarm can reduce costs on long-context calls.”
Verify a specific endpoint before routing
“Check if this endpoint URL is indexed and safe to proxy through your MCP router: https://some-mcp-server.example.com/v1/tool — I want to make sure it passes the prompt firewall before I use it.”
Technical details
Endpoint
POSThttps://token-intel.agentdiet.dev/v1/web-rag-shield-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a specific tool. Ideal for swarm orchestration, tool routing, and safely proxying through an unknown or untrusted MCP endpoint. The built-in Prompt-Guard firewall makes it preferable when prompt injection risk is a concern.
Side effects
- No matching tools found for the query — returns empty result set
- Query string too vague or short — may return irrelevant or low-confidence matches
- Endpoint URL provided for verification is not indexed — returns not-found status
- Prompt injection detected by Prompt-Guard — request blocked with firewall rejection
- Payment failure (x402) if USDC balance insufficient — returns 402 Payment Required
- Upstream MCP server unavailable — routing failure with error details
