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://cve-intel.agentdiet.dev/v1/web-rag-shield-dag)
Output
Returns a compressed manifest of matching MCP servers and A2A tools, including routing metadata, capability descriptions, and firewall/safety assessments, with up to 85% token compression applied to the results.
Example use cases
Discovering SEC filing tools for an agent
“Search the tool index for any MCP servers or A2A endpoints that can pull SEC filings or EDGAR data — I want to route my research agent to the right one.”
Finding a context compression endpoint
“Can you look up what tools are available in the MCP index for context compression or token reduction? I need to pick one for my long-document pipeline.”
Locating domain OSINT capabilities
“Search the A2A and MCP tool registry for anything related to domain OSINT or DNS intelligence so I can wire my investigation agent up to the best available option.”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/web-rag-shield-dag?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover, select, or route to an appropriate MCP server or A2A tool at runtime, especially when the full tool landscape is unknown. It is preferable over hardcoded tool lists when the agent operates across many domains and needs a single, token-efficient discovery layer with built-in safety filtering.
Side effects
- Query string too vague — returns low-relevance or empty results
- Endpoint URL verification fails if target is offline or non-compliant
- Rate limiting or payment failure under x402 protocol returns 402 status
- Prompt-Guard firewall blocks adversarial or injection-laden queries
- Index may not reflect newly added MCP servers if not yet crawled
