Perplexity

Direct GraphQL execution in Claude Desktop

Executing GraphQL queries and mutations is handled directly by your agent using `execute_graphql`. Claude Desktop fetches live records or runs batched mutations without opening a separate database client. You don't have to copy-paste responses back and forth anymore. When you ask your agent to investigate a data mismatch, it uses `get_config` to check your endpoint settings and runs the query immediately.

Instant query planning and optimization

Analyzing slow queries is straightforward when Claude Desktop uses `explain_graphql` to generate the raw SQL translation. Your agent inspects the database indices and points out exactly where you need to optimize. To ensure compatibility with your specific Hasura engine version, the agent runs `get_version` before recommending index changes. This prevents syntax mismatches on older deployments.

Real-time schema and metadata management

Modifying your Hasura engine configuration relies on `execute_metadata` to track new tables or define relationships. Your agent updates these settings without forcing you to click around the web console. If you need to back up your current structure, the tool `pg_dump` extracts the raw SQL schema from your Postgres source. Claude Desktop saves the output locally using its native filesystem access.
