clickhouse-mcp-server (sepfazeli/clickhouse-mcp-server) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: there is no public source to read and no endpoint we can reach, so there is nothing for us to inspect. No publisher has claimed this listing.
Provides AI agents safe, read-only access to a ClickHouse database, enabling table listing, query execution, schema inspection, and caching.
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.

This lets you restrict which tables, columns, and row limits are available per caller.MCP_HTTP_PORTAll four hints declared on every tool
6/6 tools missing one or more hints — list_tables (missing: idempotentHint, openWorldHint); run_query (missing: idempotentHint, openWorldHint); describe_table (missing: idempotentHint, openWorldHint), +3 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
3/6 tool handlers declare input schemas (50%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
4/6 tool handlers wrap calls in try/catch (67%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 0/6 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
