Qué hace este MCP

Analyzes PostgreSQL SQL and migrations for safety, correctness, locking risk, cost, and configurable organizational policies.

analyze_sql
Analyze SQL safety & cost
Analyze Postgres SQL/migrations for destructive operations, locking risk, correctness traps (NULL handling that silently returns wrong results), anti-patterns, and query cost. Returns a deterministic verdict (ok/warn/block) with findings. Pass the optional `schema` argument (your CREATE TABLE/INDEX DDL) to also get EXPLAIN-based cost analysis run on a throwaway scratch Postgres — no separate tool or DB connection needed.
Esquema de entrada
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['sql'], 'properties': {'sql': {'type': 'string', 'description': 'The SQL to analyze (one or more statements).'}, 'schema': {'type': 'string', 'description': 'Optional CREATE TABLE/INDEX DDL. Providing it enables EXPLAIN-based cost analysis (seq scans on large tables, etc.) on a throwaway scratch Postgres; omit it for static safety analysis only.'}, 'dialect': {'type': 'string', 'const': 'postgres'}, 'rowCountHints': {'type': 'object', 'description': 'Optional map of table name to estimated row count for realistic cost estimates.', 'additionalProperties': {'type': 'number'}}}, 'additionalProperties': False}
get_policies
Get custom org policies (Pro)
Return the custom org policy set currently stored for your Pro key — the same rules analyze_sql enforces on top of the built-ins. Read-only; returns an empty list if none are set. Use set_policies to change them.

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
set_policies
Set custom org policies (Pro)
Replace the stored custom org policy set for your Pro key (this is also how you update or clear them: send the full new set to update, or an empty array to remove all). Each policy blocks or warns on an operation against matching tables (e.g. no DELETE on payments). Policies are declarative data — validated, never executed — and apply transparently to every later analyze_sql call made with this key. Use get_policies to read the current set.
