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/workflows/execute)
Output
A list of matching MCP servers or A2A tool entries relevant to the capability query, with token-compressed descriptions and Prompt-Guard firewall screening applied. Results indicate which tools can fulfill the requested capability, along with relevant metadata such as endpoint URLs and capability summaries.
Example use cases
Discovering tools for SEC filings
“Find me MCP servers or A2A tools that can retrieve SEC filings and financial disclosures — I need the best available options indexed across the network.”
Finding GitHub security audit tools
“Search the agent tool directory for anything that supports GitHub security audits or code vulnerability scanning — show me what's available.”
Locating domain OSINT capabilities
“I need to find agent tools that can do domain OSINT and email verification — can you search the MCP index and tell me which servers support those capabilities?”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability without maintaining its own tool registry. Ideal for swarm orchestration scenarios where the agent must find and route to specialized tools at runtime. Prefer this over hardcoded tool lists when the capability landscape is broad (500+ servers) and token efficiency matters due to the 85% compression feature.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or unsupported capability queries
- Rate limiting or payment failure (HTTP 402) if x402 payment not properly handled
- Upstream MCP server index temporarily unavailable causing partial results
- Malicious prompt injection in query blocked by Prompt-Guard firewall with rejection response
