Neon MCP Server lets AI agents manage Neon Postgres databases directly, including creating and branching databases, running SQL queries, managing schemas, inspecting database structure, and working with projects and branches.
Claude is Anthropic's AI assistant, available as a desktop app and in Cowork. It supports custom connectors, so it can call MCP servers directly from a chat.
This guide connects Neon MCP to Claude Desktop through MewCP, so Claude Desktop can use Neon MCP's 114 tools, like list_organizations, run_sql and run_sql_transaction, without your Neon MCP credentials ever reaching the app.
Neon MCP signs in through managed OAuth. MewCP stores the token encrypted, refreshes it before it expires and injects it only at call time. Your agent never holds it, so it can never leak it.

Other clients
Neon MCP works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Neon MCP tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
In Claude, open Settings → Connectors, then choose Add custom connector.
Name it "mewcp" and paste the URL.
A browser window opens the first time the client connects. Sign in and approve access. No API key needed.
Start a new chat and ask: "List the tools you can use from MewCP." You should see your connected apps.
List all organizations the current user belongs to. Supports optional `search` parameter to filter by name or ID.
Execute one SQL statement on a Neon database. If a prior step created a temporary branch, pass that branch_id. NEVER run destructive SQL autonomously; always ask the user first.
Execute multiple SQL statements as one transaction. If a prior step created a temporary branch, pass that branch_id. NEVER run destructive SQL autonomously; always ask the user first.
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).
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).
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.
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.
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).
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.
Read Neon Auth config for a branch with OAuth and SMTP secrets redacted as "***redacted***". Requires provision_neon_auth first.
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).
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.
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.
List queries from pg_stat_statements by execution time, slowest first. For sizes, indexes, locks, cache, bloat, or replication use inspect_database.
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.
Search across all organizations, projects, and branches by keyword. Returns matching items with id, title, and URL. Query must be at least 3 characters. Do not use when you need all projects (use `list_projects` instead).
Fetch detailed information about a specific organization, project, or branch using the ID returned by the `search` tool.
List Neon documentation page slugs from neon.com/docs/llms.txt. Call this before get_doc_resource; do not guess slugs.
Fetch one Neon documentation page as markdown. Pass a slug from list_docs_resources (for example docs/guides/prisma.md).
Send anonymous feedback about Neon or this MCP server to the Neon team. Only call this when the user asks to give feedback. Sends only the feedback text, not account, project, or connection details.
List Neon projects you own. Returns every page. Pass limit to cap how many. There is no `cursor` argument. `org_id` is optional: organization API keys use their organization; personal API keys auto-select when unambiguous and otherwise return the IDs to choose from.
Retrieves the project record (settings, compute, usage). Call `list_branches` for branches.
Creates a Neon project and waits until the default compute is ready. `org_id` is optional: organization API keys use their organization; personal API keys auto-select when unambiguous and otherwise return the IDs to choose from. Does not return a connection string; call `get_connection_string` with the project id.
Updates the specified project.
Delete a Neon project and all its data. NEVER run autonomously; always ask the user first. For a single branch, use `delete_branch`.
Recovers a deleted project within the 7-day deletion recovery period.
Retrieves details about users who have access to the project, including the permission `id`, the granted-to email address, and the date project access was granted.
Lists organization members and their per-project roles for an org-owned project. Returns every page. Pass limit to cap how many.
Lists Neon regions available to the authenticated account.
Lists operations for a project. Omitting `limit` returns every remaining page. There is no `cursor` argument.

Reset a branch to its parent's current HEAD. Discards every change the branch has written since it diverged. NEVER run autonomously; always ask the user first. `preserve_under_name` saves the current state first and is required when the branch has children; those children move to the new branch. Point-in-time restore is `restore_snapshot`. branch_id is a branch id (br-...), not a branch name. Call list_branches to resolve a name.
Compare one database's SQL schema on a branch to another. `database_name` is required. Omit `base_branch_id` to compare against the parent; it is a branch id (`br-...`), not a name. Pass `lsn`, `timestamp`, `base_lsn`, or `base_timestamp` only for a point-in-time comparison. branch_id is a branch id (br-...), not a branch name. Call list_branches to resolve a name.
