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 tool entries from the 500+ item index, including metadata about each tool's capabilities, schema, and safety status after Prompt-Guard firewall filtering.
Example use cases
Discover context compression tools
“Can you search the agent tool index for anything that does context compression or token reduction? I want to find an MCP server I can plug into my pipeline to cut down prompt size.”
Find on-chain risk analysis agents
“Search the tool directory for A2A or MCP endpoints that cover on-chain risk or DEX token intelligence — I'm building a crypto research swarm and need to know what's indexed.”
Verify a specific endpoint is safe to use
“Can you check whether this endpoint URL is listed and passes the Prompt-Guard firewall in the tool index: https://someagent.example.com/v1/tool — I want to make sure it's safe before routing my swarm through it.”
Technical details
Endpoint
GEThttps://token-intel.agentdiet.dev/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or route to MCP servers or A2A tools from a large curated index without managing multiple separate connections. It is especially valuable when you need token-efficient tool manifests, want Prompt-Guard firewall protection before proxying to unknown agents, or need to verify whether a specific endpoint URL is indexed and compliant. Prefer it over manual tool registries when building multi-agent swarms that require dynamic capability discovery.
Side effects
- Empty results if query terms don't match any indexed tool capabilities
- Firewall rejection if a submitted URL is flagged as unsafe by Prompt-Guard
- Payment required error (HTTP 402) if x402 payment is not included or fails
- Malformed query (missing or empty 'query' parameter) returns validation error
- Index may be stale if recently added MCP servers haven't been crawled yet
