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://mcp-security.agentdiet.dev/v1/workflows)
Output
A compressed, token-optimized list of matching MCP servers and A2A tools from a 500+ item index, including capability descriptions, endpoint metadata, and safety-screened routing information. Results pass through a Prompt-Guard firewall to block malicious tool responses.
Example use cases
Discover tools for on-chain risk analysis
“Search the MCP index for any tools or A2A agents that can do on-chain smart contract risk scoring or honeypot detection — I want to wire one into my trading bot.”
Find a prompt injection firewall tool
“I need to find an MCP server in your index that has prompt-guard or prompt firewall capabilities to protect my agent swarm from injection attacks.”
Locate GitHub audit tools for agent pipeline
“Can you search the A2A and MCP tool registry for anything that does GitHub security audits or code repository scanning? I'm building a DevSecOps agent and need a ready-made tool to call.”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/workflows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability without hardcoding individual tool connections. Especially valuable when building multi-agent swarms, when you want 85% token compression on tool metadata, or when you need a Prompt-Guard firewall screening tool responses before they reach your agent context.
Side effects
- Empty query string returns validation error (minLength:1 required)
- No matching tools found for the query returns empty result set
- Upstream MCP server registry unavailable causes degraded results
- x402 payment not fulfilled results in 402 Payment Required response
- Query too vague may return low-relevance or overly broad tool matches
