Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• complete_database_migrationComplete Database Migrationcan change or delete data

  Apply or discard a prepared migration and delete the temporary branch. NEVER run autonomously; always ask the user first. Pass migration_id, migration_sql, database_name, project_id, temporary_branch_id, and parent_branch_id from prepare_database_migration. Set apply_changes false to discard; omitting it applies the migration.

• complete_query_tuningComplete Query Tuningcan change or delete data

  Apply or discard query-tuning changes and delete the temporary branch. NEVER run autonomously. Before calling, apply suggested SQL with run_sql on the temporary branch and re-run explain_sql_statement. Pass the tuning_id from prepare_query_tuning, not the branch id, plus temporary_branch_id. Set apply_changes true to apply; omitting it discards. Call this even when the user rejects the changes. Do not use prepare_database_migration.

• describe_branchDescribe Branchread-only

  Get a tree view of all objects in a branch, including databases, schemas, tables, views, and functions. Do not use when you only need table names (use `get_database_tables` instead) or column detail (use `describe_table_schema` instead).

• describe_table_schemaDescribe Table Schemaread-only

  Get column definitions, data types, and constraints for a specific table. Do not use when you need all tables in a database (use `get_database_tables` instead).

• explain_sql_statementExplain SQL Statementcan change or delete data

  Generate the execution plan for a SQL statement. When `analyze` is true, PostgreSQL executes the statement and any side effects. Use `analyze: false` to inspect a statement without executing it. Never analyze potentially destructive SQL autonomously. Do not use when you need query results (use `run_sql` instead).

• fetchFetchread-only

  Fetch detailed information about a specific organization, project, or branch using the ID returned by the `search` tool.

• get_connection_stringGet Connection Stringread-only

  Get a PostgreSQL connection string for a Neon database. The branch must have a compute endpoint. `create_project` and `create_branch` do not return one; call this after they succeed. Branch, compute, and database are optional and resolved automatically if not specified; `project_id` follows the connection scope. Requires write access: the connection string carries a privileged role password, so it is unavailable in read-only mode. A read-only caller who needs a DATABASE_URL must copy it from https://console.neon.tech manually.

• get_database_tablesGet Database Tablesread-only

  List all tables in a Neon database. Do not use when you need column-level detail for a specific table (use `describe_table_schema` instead).

• get_docGet Documentation Pageread-only

  Fetch one neon.com page as markdown. Pass the slug of a search_docs hit (for example docs/guides/prisma).

• get_neon_auth_configGet Neon Auth configurationread-only

  Read Neon Auth config for a branch with OAuth and SMTP secrets redacted as "***redacted***". Requires provision_neon_auth first.

• inspect_databaseInspect Databaseread-only

  Run one read-only neon inspect db check (pick `check` from the input schema). Not for arbitrary SQL (`run_sql`), one statement's plan (`explain_sql_statement`), or applying indexes (`prepare_query_tuning`). Omit `database_name` to cover every database; some checks are compute-wide. If a check needs an extension, the tool names `CREATE EXTENSION`; ask before running it.

• list_organizationsList Organizationsread-only

  List all organizations the current user belongs to. Supports optional `search` parameter to filter by name or ID.

• list_slow_queriesList Slow Queriesread-only

  List queries from pg_stat_statements by execution time, slowest first. For sizes, indexes, locks, cache, bloat, or replication use inspect_database.

• prepare_database_migrationPrepare Database Migration

  Apply a schema change on a temporary branch and return a migration_id. Test with run_sql on that branch, ask the user, then complete_database_migration — even if they reject, so the temporary branch is deleted. Pass every field from the prepare response.

• prepare_query_tuningPrepare Query Tuning

  Analyze a slow query on a temporary branch and return a tuning_id. Apply suggested SQL with run_sql on that branch, re-run explain_sql_statement there, then complete_query_tuning with the tuning_id (not the branch id) — apply_changes true if they accept, omit it or pass false if they reject, so the temporary branch is deleted. Do not use prepare_database_migration.
