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/tool-search)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with compressed metadata (85% token reduction) and Prompt-Guard firewall filtering applied, including tool names, capabilities, and routing information.
Example use cases
Discovering SEC filing tools for agent
“Can you search the tool index for any MCP servers or A2A agents that handle SEC filings or financial document retrieval? I need to route my research agent to the right one.”
Finding GitHub security audit tools
“Look up what MCP tools are available for GitHub security auditing — I want my swarm to automatically pick the best one for scanning repos.”
Verifying a specific MCP endpoint
“Can you check if this endpoint URL is a valid, compliant MCP server in the index: https://some-mcp-service.example.com/api — I want to know if it's safe to route through.”
Technical details
Endpoint
GEThttps://token-intel.agentdiet.dev/v1/tool-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a specific tool. It is especially useful in swarm orchestration, when building tool-agnostic pipelines, or when you want a single connection point that indexes 500+ servers with built-in prompt injection protection and token compression.
Side effects
- Empty query returns validation error (minLength:1 not met)
- No matching tools found for obscure capability query returns empty result set
- Endpoint URL verification fails if the URL is malformed or unreachable
- Rate limiting or payment failure (HTTP 402) if x402 USDC payment is not supplied
- Index may be stale if recently added MCP servers haven't been crawled yet
