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/rag-context-sanitizer)
Output
A compressed, prompt-guard-filtered list of matching MCP servers or A2A tools from a 500+ item index, with up to 85% token reduction applied, relevant to the capability query or verified endpoint URL provided.
Example use cases
Discover tools for SEC filing data
“Search the MCP meta-router for any A2A or MCP tools that can pull SEC filings — I need to find the right server to route my agent through for financial document retrieval.”
Find safe proxy for on-chain risk
“Look through the MCP tool index for servers that handle on-chain risk analysis or smart contract security — I want results filtered through the Prompt-Guard firewall so I know it's safe to use.”
Route agent to company enrichment tool
“Can you search the A2A and MCP tool registry for anything related to 'company enrichment' or 'B2B lead data'? I want to connect my swarm agent to the best available option via a single endpoint.”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/workflows/rag-context-sanitizer?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 connections. It is especially useful for swarm architectures that need a single safe-proxy entry point, or when token budget is constrained and 85% compression is valuable. Prefer it over direct MCP server connections when Prompt-Guard firewall sanitization is needed.
Side effects
- Empty result set if query does not match any indexed MCP/A2A tools
- Payment required (HTTP 402) if x402 micropayment is not included
- Rate limiting if too many queries are sent in quick succession
- Malformed or injection-laden queries rejected by Prompt-Guard firewall
- Timeout if the meta-router index is temporarily unavailable
