debmatic-mcp (claymore666/ccu-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
Integrates HomeMatic smart home devices (via CCU3, RaspberryMatic, or debmatic) as MCP tools, enabling natural language query and control of rooms, devices, programs, and system variables.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

26/26 tools missing one or more hints — set_value (missing: readOnlyHint); put_paramset (missing: readOnlyHint); set_system_variable (missing: readOnlyHint), +23 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
19/26 tool handlers declare input schemas (73%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 8/26 tool handlers wrap calls in try/catch (31%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
18/26 tools referenced in tests (69%)
Write tests that reference each tool by name so every tool has at least one test.
