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://onchain-risk.agentdiet.dev/v1/b2b-osint-dag)
Output
A structured response listing matched MCP servers or A2A tools relevant to the query, with metadata such as endpoint URLs, capability descriptions, token-compressed summaries, and any firewall/safety flags applied by the Prompt-Guard layer.
Example use cases
Finding tools for SEC filings
“Can you search the MCP tool index for anything that handles SEC filings or public company financial data? I want to find the best agent endpoint to route my finance queries to.”
Discovering prompt firewall capabilities
“Search the A2A and MCP tool directory for endpoints that offer prompt injection protection or a prompt guard firewall — I need to know what's available before I wire up my agent pipeline.”
Verifying an agent endpoint URL
“Can you check if this URL is indexed and compliant in the MCP tool router — https://onchain-risk.agentdiet.dev/v1/b2b-osint-dag — and tell me what capabilities it exposes?”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/b2b-osint-dag?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 individual tool URLs. It is especially valuable in swarm or multi-agent architectures where a single routing layer with 85% token compression and built-in prompt safety is preferred over maintaining dozens of separate tool connections.
Side effects
- Empty query string returns validation error (minLength:1)
- Query with no matching tools returns empty results set
- Endpoint URL verification for non-indexed URLs may return not-found
- Firewall may block or flag queries containing prompt-injection patterns
- Service unavailability or upstream MCP server timeouts may degrade results
