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/defi-token-due-diligence)
Output
Returns a compressed, token-efficient listing of matching MCP servers or A2A tools from a 500+ item index, including tool names, capability descriptions, and endpoint metadata. If an endpoint URL is provided, returns verification and safety firewall status. Response is filtered through a Prompt-Guard firewall to block injected content.
Example use cases
Finding an MCP server for SEC filings
“Search the MCP tool index for any servers or A2A tools that handle SEC filings or financial document retrieval — I want to know what's available and what each one does.”
Verifying a specific MCP endpoint
“Can you check whether this MCP endpoint URL is legitimate and indexed: https://some-agent.example.com/mcp — I want to know if it's in the directory and passes the safety firewall.”
Discovering GitHub security audit tools
“I'm building an agent pipeline and need a tool for GitHub security auditing — search the A2A and MCP tool index for anything that covers GitHub code scanning or repo security.”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/workflows/defi-token-due-diligence?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 hard-coding individual tool URLs. Especially useful for swarm orchestration scenarios where the agent needs to route subtasks to the best available tool, or when you want to verify a third-party MCP endpoint for safety before connecting to it. Prefer this over manually maintaining a tool registry or connecting directly to untrusted MCP servers.
Side effects
- Empty query string returns 400 validation error
- No matching tools found for obscure capability queries returns empty results
- Endpoint URL verification may fail if the remote server is offline
- Payment not completed (HTTP 402) blocks access
- Firewall may redact or block results containing suspicious prompt content
