Safely query Postgres with performance diagnostics, index tuning, and health checks.
The materials indicate an open-source MIT-licensed Postgres MCP server with no declared API keys or external remote endpoints, and no clear high-risk red flags are evident. Its core capabilities involve local code/process execution and access to PostgreSQL data, which are normal cautions for this tool category; use least privilege and verify the repository implementation.
The materials explicitly state there are no required keys or environment variables, and no API token or third-party credential requirement is shown. In practice, PostgreSQL connectivity may still rely on standard DB connection credentials, but the provided materials do not show extra credential collection or abuse indicators.
No external remote endpoint is declared, and there is no description of sending data to unknown third-party services. However, as a Postgres MCP server, its normal function typically requires connecting to the target PostgreSQL instance and exchanging query/diagnostic data; this is expected network behavior, and you should ensure it only connects to intended databases.
The system checks indicate that this tool executes code; as an MCP tool, it typically runs a local service process. The description mentions 'safe SQL execution,' 'explain plans,' 'health checks,' and 'index tuning,' indicating it performs database-related operations, but the materials do not show system-level privilege requests beyond the stated purpose.
By design, the tool needs access to PostgreSQL schemas, query plans, health status, and potentially index configuration, implying the ability to read database metadata and execute SQL. The current materials do not show requests for unrelated local file or system resource access, but it should be restricted to least database privilege and ideally not pointed at highly sensitive production databases.
Positive factors include auditable source code and an MIT open-source license, which materially reduce supply-chain risk. Cautions remain because it comes from a third-party registry, has 0 GitHub stars, and unknown maintenance status, so trust is limited and the repository code, releases, and dependencies should be reviewed before use.

Please inspect the execution plan for this slow Postgres query, identify bottlenecks, and suggest actionable index optimizations: SELECT * FROM orders WHERE customer_id = 1024 AND created_at >= NOW() - INTERVAL '30 days' ORDER BY created_at DESC;
Returns execution plan analysis, bottleneck explanations, and recommended indexes or query rewrites.
Please safely execute the following SQL in read-only mode and summarize the results: SELECT status, COUNT(*) AS total FROM payments GROUP BY status ORDER BY total DESC;
Returns a summary of query results while ensuring the operation remains safely read-only.
Please run a health check on the current Postgres instance, focusing on connections, slow queries, cache hit rate, and potential performance risks, then provide recommendations.
Returns a database health report with key metrics, risk items, and recommended optimizations.
