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/b2b-osint-dag)
Output
Returns a compressed (up to 85% token reduction) list of matching MCP servers or A2A tools relevant to the query, including their endpoint metadata, capability descriptions, and routing information — filtered through a Prompt-Guard firewall for safe use in agent pipelines.
Example use cases
Discover tools for crypto risk analysis
“Find me MCP servers and A2A tools in the index that can do on-chain risk analysis or DEX token intelligence — I want to see what's available before I build my agent pipeline.”
Route to email verification agents
“Search the tool index for any MCP or A2A endpoints that support email verification and B2B lead enrichment so I can wire them into my swarm.”
Verify an endpoint's capabilities
“Can you check whether https://token-intel.agentdiet.dev/v1/b2b-osint-dag is indexed and what capabilities it's listed as supporting?”
Technical details
Endpoint
POSThttps://token-intel.agentdiet.dev/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover and route to MCP servers or A2A tools at runtime without hardcoding individual tool URLs. It is especially valuable for swarm orchestration, tool-augmented agents, or when you want token-efficient tool metadata with built-in prompt injection protection. Prefer this over manually curating tool lists or querying individual MCP registries.
Side effects
- Empty query string returns validation error (minLength:1 enforced)
- No matching tools found for obscure or misspelled capability query
- Prompt-Guard firewall may block queries containing injection patterns
- Payment required (HTTP 402) if x402 credentials are missing or invalid
- Idempotency-Key collision may cause cached responses on retries
