Middleware Query

Natural-language read-only querying for MySQL, Redis, and MongoDB with explicit connection configuration (host, port, username, password), guarded query plan...

This skill appears to do what it says: translate NL into guarded, read-only DB queries and run them against explicit connection profiles. Before installing: 1) Keep your connections.json local and gitignored (the docs make this recommendation). 2) Review and control which DB credentials you give it — the tool needs host/port/user/password to connect. 3) If you don't want any queries or user text sent to OpenAI, do not set OPENAI_API_KEY (the planner will fall back to a local rule-based router). 4) Run the Python dependencies in an isolated environment and inspect connections.json and any saved plan files if you keep them. 5) Note masking is implemented for common sensitive field names, but confirm it covers any custom secret field names you care about.

Type: OpenClaw Skill Name: middleware-query Version: 1.0.0 The middleware-query skill bundle provides a structured and safety-conscious framework for querying MySQL, Redis, and MongoDB. It implements a multi-stage pipeline (Plan -> Guard -> Execute) that enforces read-only operations through regex patterns and command whitelists in scripts like query_sql.py, query_redis.py, and query_mongo.py. Additionally, it includes a sensitive data masking utility in _common.py to redact passwords and PII from query results, and it follows best practices by requiring local configuration of credentials via a gitignored connections.json file.
