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/web-rag-shield-dag)
Output
Returns a list of matching MCP servers and A2A tools relevant to the query, including endpoint metadata, capability descriptions, and firewall-validated routing information, with up to 85% token compression applied to the response payload.
Example use cases
Discover tools for SEC filing data
“Search the MCP meta-router for any tools or servers that handle SEC EDGAR filings and financial intelligence — I want to find the right endpoint for pulling 10-K reports.”
Route agent to GitHub security auditor
“I need to find an MCP server that can audit GitHub repositories for license risk and supply-chain vulnerabilities — can you search the tool index for 'github security'?”
Find context compression tools for swarm
“Search the A2A tool registry for anything related to 'context compression' or token reduction — I'm building a multi-agent swarm and need to cut down token usage between hops.”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/web-rag-shield-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to use for a given capability, rather than hardcoding a specific tool endpoint. Ideal for swarm orchestration, meta-routing, and scenarios where the right downstream tool is unknown at design time. Prefer this over direct tool calls when you want built-in prompt-injection firewall protection on discovered tool responses.
Side effects
- Empty query string returns validation error (minLength:1 required)
- Query too vague may return no matching tools or low-confidence results
- Prompt-Guard firewall may block queries that resemble injection patterns
- Underlying MCP server index may be stale if recently added servers haven't been indexed
- Payment not satisfied (HTTP 402) if x402 micropayment of $0.01 USDC is not completed
