Arne Kellmann Consulting is a remote MCP server published at arnekellmann.de. It has been probed 6 times since 9/12/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 711 ms, a delay an agent will notice. It offers a narrow, focused set of 3 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
list_services — Name does not clarify if it lists services, pricing, or contact info.read_document — Description lacks context for when to use path-based document access.search_docs — No explanation of how to interpret search results or handle no matches.Risk: low

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
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.
