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-compiler.agentdiet.dev/v1/security-audit-dag)
Output
Returns a token-compressed index of matching MCP servers or A2A tools relevant to the query, along with security/firewall status for any verified endpoint URLs, capability metadata, and routing recommendations.
Example use cases
Discovering context compression tools
“I need to find MCP servers that support context compression — can you search the tool index and show me what's available along with any safety flags?”
Verifying an endpoint before calling it
“Before I use this endpoint https://some-mcp-server.example.com/v1/tool, can you run it through the security audit to check if it's safe and legitimate?”
Finding SEC filings capability
“Which MCP tools in the index can retrieve SEC filings? Search for 'sec filings' and give me the top matches with their metadata.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/security-audit-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover and vet MCP servers or A2A tools by capability without connecting to each one individually, or when you need to verify a specific endpoint URL against a prompt-injection firewall before trusting its output. Prefer it over direct MCP discovery when you want 85% token-compressed results and a safety layer bundled into a single call.
Side effects
- Empty query string returns validation error (minLength:1 not met)
- No matching tools found for obscure capability queries
- Endpoint URL verification may time out if the target server is unreachable
- Payment failure (HTTP 402) if x402 payment header is missing or insufficient
- Firewall may flag legitimate endpoints as suspicious, causing false positives
