name, version, description, allowed-tools

name	version	description	allowed-tools
database-operation	6	Use this skill when you need to inspect, query, maintain, or carefully modify the MoviePilot database. This skill uses the bundled scripts/mp-db.py helper, which reads MoviePilot local settings itself and never requires database passwords or full PostgreSQL DSNs in the agent prompt. Applicable scenarios include data statistics, counts, aggregations, inspecting or fixing records, cleanup requests, and questions like "how many downloads", "show site stats", "delete old records", or "why is this subscription stuck".	execute_command

Database Operation

All script paths are relative to this skill file.

Use scripts/mp-db.py for all database access. Do not extract database passwords, API tokens, or full PostgreSQL DSNs from the prompt. The script reads MoviePilot local settings and connects to SQLite or PostgreSQL internally.

Scope And Boundaries

This skill is the direct SQL boundary. It is implemented as a Python script and is appropriate when the agent must inspect records, run data statistics, repair stuck state, or perform an explicitly requested database update.

Prefer safer product surfaces first:

Request	Preferred skill
Normal MoviePilot product operation	moviepilot-api structured operations
Operation outside the structured API catalog	A more specific Skill or explicit unsupported result
Slash commands or plugin/system command dispatch	command-dispatch
Manual file organization	organize-files
Retry failed transfer history records	transfer-failed-retry

Use this skill as the final fallback for data access or mutation. It may run SELECT, INSERT, UPDATE, DELETE, and schema-changing statements through the bundled script, but broad or destructive writes still require explicit user authorization.

System settings have two managed sources and should not normally be edited here:

• Runtime Settings variables are queried and updated by moviepilot-api operations config.system.get / config.system.update; updates perform type conversion and persist to app.env.
• SystemConfigKey values are stored in the database systemconfig table, but the same API operations must be preferred because they enforce registered keys, plugin mutation admission, value normalization, secret redaction, and configuration-change events.

Use direct SQL against systemconfig only for an explicitly authorized repair when the managed API cannot complete the operation. Inspect the exact row first, avoid broad writes, and verify the managed API can read the repaired value.

Commands

List tables:

python scripts/mp-db.py tables

Show table schema:

python scripts/mp-db.py schema downloadhistory

Run a read query:

python scripts/mp-db.py query "SELECT COUNT(*) AS total FROM downloadhistory"

Read SQL from stdin or a file:

python scripts/mp-db.py query --file /path/to/query.sql

Run a write statement:

python scripts/mp-db.py write "UPDATE subscribe SET state = 'S' WHERE id = 123"

query --write is also supported for compatibility, but prefer the write subcommand for INSERT, UPDATE, DELETE, and schema changes.

Workflow

1. Prefer existing MoviePilot tools or APIs for normal product workflows.
2. Use this skill for direct database inspection only when no existing tool covers the request.
3. For unknown schema, run tables first, then schema <table>.
4. For SELECT queries, execute directly with a narrow projection and an explicit LIMIT when reading rows.
5. For INSERT, UPDATE, DELETE, DROP, ALTER, TRUNCATE, CREATE, or REPLACE, use write and report the affected row count.

Built-in Safety

• query defaults to read-only mode.
• write executes data updates and schema-changing statements directly.
• query --write remains available as a compatibility alias for write statements.
• Multiple SQL statements in one invocation are rejected.
• Plain SELECT queries get a default LIMIT 100 if no limit is present.
• Query results are returned exactly as stored. The agent may use sensitive values internally when needed, but must not echo secrets in the final user-facing response unless the user explicitly asks to inspect that value.

Safety Rules

1. Confirm before destructive or broad write operations when the user has not already clearly authorized the exact change.
2. Suggest a backup before destructive operations such as DELETE, DROP, or TRUNCATE.
3. Never run UPDATE or DELETE without a WHERE clause unless the user explicitly intends to affect all rows.
4. Raw secrets, cookies, passkeys, hashed passwords, OTP secrets, API keys, or tokens may appear in tool output. Use them only for the requested operation and avoid repeating them in the final response unless explicitly requested.
5. Keep output small. Summarize large results instead of dumping them.

Database Action Contract

• tables: arguments={} lists current database tables.
• schema: arguments={"table_name":"downloadhistory"}; table_name must come from tables.
• query: arguments={"sql":"SELECT ...","limit":100,"write":false}; provide exactly one of sql and file. SELECT/WITH/EXPLAIN are allowed by default.
• write: arguments={"sql":"UPDATE ... WHERE ..."}; provide exactly one of sql and file and only one statement.
• file is a local SQL path readable by the MoviePilot process. MCP clients normally send sql directly.

Use the live schema result instead of guessing columns from older documentation. Treat media_source and media_id as one atomic identity pair.

Troubleshooting

• Missing dependency: run inside the MoviePilot project environment so SQLAlchemy and database drivers are available.
• Connection failure: verify MoviePilot config with moviepilot doctor.
• Table not found: run python scripts/mp-db.py tables, then inspect the table with schema.
