Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router
Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router is a paid API for AI agents from cve-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches an index of 500+ MCP servers and A2A tools by capability query, returning compressed, firewall-filtered tool metadata via a single connection.

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/tool-broker)
Output
Returns a structured list of matching MCP servers or A2A tools with compressed metadata, capability summaries, and endpoint details, filtered through a Prompt-Guard firewall to remove malicious content. Endpoint verification queries return compliance and safety status.
Example use cases
Finding a GitHub security audit tool
“Search through the MCP tool index for anything that can do GitHub security audits or code vulnerability scanning — I need to find the right server to plug into my agent pipeline.”
Discovering context compression capabilities
“Can you look up which MCP servers in the index support context compression or token reduction? I want to reduce how many tokens my swarm is burning per call.”
Verifying an endpoint for MCP compliance
“Check whether https://some-agent.example.com/api is a valid MCP-compatible endpoint — I want to know if it's safe and compliant before routing my agent traffic through it.”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/tool-broker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover and route to the right MCP server or A2A tool from a large index without managing individual connections to each. Especially valuable when token efficiency matters (85% compression), when security filtering of tool metadata is required (Prompt-Guard firewall), or when building multi-agent swarms that need a single reliable meta-router rather than hardcoded tool lists.
Side effects
- Missing or empty query parameter returns a validation error
- No matching tools found for the given capability query returns an empty result set
- Queried endpoint URL is unreachable or malformed returns a verification failure
- Payment not resolved (x402) results in 402 response blocking access
- Prompt injection attempts detected by Prompt-Guard firewall are blocked and flagged
