FDA Data MCP is a remote MCP server published at www.regdatalab.com. It has been probed 31 times since 9/4/2026. It answered in 31 of them (100.0%), a near-uninterrupted record. Median response time is 670 ms, a delay an agent will notice. It exposes a broad tool surface of 48 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Clean FDA regulatory data: company resolution, facilities, recalls, inspections, approvals.
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.

Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
