Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "percona-pg": {
      "command": "npx",
      "args": [
        "-y",

      ],
      "env": {
        "KUBECONFIG_PATH": "your-value",
        "PERCONA_MODE": "your-value",
        "PERCONA_NAMESPACE": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add percona-pg --env KUBECONFIG_PATH=your-value --env PERCONA_MODE=your-value --env PERCONA_NAMESPACE=your-value -- npx -y @dockndevai/mcp-percona-pg

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "percona-pg": {
      "command": "npx",
      "args": [
        "-y",
        "@dockndevai/mcp-percona-pg"
      ],

        "KUBECONFIG_PATH": "your-value",
        "PERCONA_MODE": "your-value",
        "PERCONA_NAMESPACE": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "percona-pg": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",

        "PERCONA_MODE": "your-value",
        "PERCONA_NAMESPACE": "your-value"
      }

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

KUBECONFIG_PATH env
Path to a kube-config file that can reach the Percona Operator namespaces (empty = default resolution).
PERCONA_MODE env
Access mode: read-only | read-write | admin.
PERCONA_NAMESPACE env
Default namespace for PerconaPGCluster resources when a tool omits one.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is MCP Percona Pg safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.3) reached the registry 12 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

mcp-percona-pg

A Model Context Protocol server for the [Percona Operator for PostgreSQL](https://docs.percona.com/percona-operator-for-postgresql/2.0/). It lets an MCP-capable client (Claude Desktop, Claude Code, Cursor, …) operate PostgreSQL + PgBouncer clusters on Kubernetes — topology, connection pooling, tuning, backups/PITR, DR, extensions, and lifecycle — with behaviour controlled entirely by flags.

It drives the operator's custom resources (PerconaPGCluster, PerconaPGBackup, PerconaPGRestore, PerconaPGUpgrade) through your kube-config, so the model works the way you already do: *"scale dev-pg to 3 replicas"*, *"switch pooling to transaction mode"*, *"restore prod-pg to 12:00 UTC"*.

Safe by default: it starts read-only, can be scoped to an allowlist of namespaces and clusters, protects critical clusters from mutation, gates restore / upgrade / delete behind separate opt-ins, and requires typed confirmation for high-impact actions. It never reads or returns database credentials.

Features

Discovery & status — list clusters, per-cluster summary and raw .status (Patroni members, PostgreSQL/PgBouncer readiness), connection endpoints, backups and restores.
Connection pooling — read and update PgBouncer pool_mode and the global pool tunables (default_pool_size, max_client_conn, …).
PostgreSQL tuning — read/merge parameters via spec.patroni.dynamicConfiguration (the only Patroni-safe path).
Lifecycle — scale PostgreSQL/PgBouncer, pause/resume, toggle built-in extensions, on-demand backups.
DR & recovery — restore / point-in-time recovery, promote a standby, major-version upgrades — each individually gated.

Security model

Layer	Flag	Effect
Access mode	`PERCONA_MODE`	`read-only` → `read-write` → `admin`; over-privileged tools are never registered
Namespace/cluster allowlists	`PERCONA_NAMESPACE_ALLOWLIST`, `PERCONA_CLUSTER_ALLOWLIST`	scope what the agent can touch
Protected clusters	`PERCONA_PROTECTED_CLUSTERS`	readable, never mutated/restored/deleted
Restore / upgrade / delete	`PERCONA_ALLOW_RESTORE`, `PERCONA_ALLOW_UPGRADE`, `PERCONA_ALLOW_DELETE`	separate opt-ins on top of admin mode
Confirmation	`PERCONA_REQUIRE_CONFIRMATION`	high-impact ops require echoing the cluster name
Dry-run / audit	`PERCONA_DRY_RUN`, `PERCONA_AUDIT_LOG`	validate-only; JSON audit line per guarded op
Interactive confirmation	(automatic)	destructive & high-impact ops prompt the human to approve via MCP elicitation before running; fall back to the `PERCONA_ALLOW_*` gates when the client can't elicit

Tools

Read (read-only+): list_contexts, list_clusters, get_cluster, get_cluster_status, get_connection_info, get_pgbouncer_config, get_pg_parameters, list_backups, list_restores

Write (read-write+): scale_cluster, set_pgbouncer_config, set_pg_parameters, pause_cluster, toggle_builtin_extension, create_backup

Admin (admin): restore_cluster (needs PERCONA_ALLOW_RESTORE), upgrade_cluster (needs PERCONA_ALLOW_UPGRADE), promote_standby, delete_backup / delete_cluster (need PERCONA_ALLOW_DELETE)

Quickstart — add to your agent

Published on npm as @dockndevai/mcp-percona-pg. No clone or build needed — your MCP client runs it on demand with npx. Start in `read-only` mode; see .env.example for every variable and docs/CLIENTS.md for the full per-client guide.

Claude Code (CLI)

claude mcp add percona-pg -e PERCONA_MODE="read-only" -e PERCONA_NAMESPACE="postgres-operator" -- npx -y @dockndevai/mcp-percona-pg

Claude Desktop · Cursor · Windsurf — same block in claude_desktop_config.json, .cursor/mcp.json, or ~/.codeium/windsurf/mcp_config.json:

"mcpServers": { "percona-pg": { "command": "npx", "args": ["-y", "@dockndevai/mcp-percona-pg"], "env": { "PERCONA_MODE": "read-only", "PERCONA_NAMESPACE": "postgres-operator" } } } }

OpenAI Codex CLI — in ~/.codex/config.toml:

[mcp_servers.percona-pg]

command = "npx" args = ["-y", "@dockndevai/mcp-percona-pg"] env = { PERCONA_MODE = "read-only", PERCONA_NAMESPACE = "postgres-operator" }

Example prompts

*"List the PostgreSQL clusters and show me the status of dev-pg."*
*"What pool_mode is dev-pg using, and how big is the default pool?"* → get_pgbouncer_config
*"Set dev-pg PgBouncer to transaction pooling with default_pool_size 25."* (needs read-write)
*"Bump shared_buffers to 512MB on dev-pg."* (needs read-write)
*"Take a full backup of dev-pg to repo1."* (needs read-write)
*"Restore dev-pg to 2026-08-30 12:00:00+00."* (needs admin + PERCONA_ALLOW_RESTORE + confirmation)

Prerequisites

A Kubernetes cluster running the Percona Operator for PostgreSQL v2 (pgv2.percona.com/v2).
A kube-config the server can read. For safety, use a ServiceAccount/RBAC scoped to the operator's namespaces and to the pgv2.percona.com resources you want the agent to see.

Run from source (development)

Prefer the published package above. To run from a clone:

npm install

npm run build node dist/index.js # with the environment variables set

Develop

npm run dev

npm test # security policy + annotations npm run typecheck

Publishing

This server ships a server.json for the official MCP registry and an mcpName for npm ownership validation. See [PUBLISHING.md](PUBLISHING.md).
