Registry nameio.github.timescale/tiger-cli

Install

Overview

Description from the maker (original English)

Provides programmatic access to Tiger Cloud services, databases, and documentation.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other
  • You need to fill in: TIGER_PUBLIC_KEY, TIGER_SECRET_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: TIGER_PUBLIC_KEY, TIGER_SECRET_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

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": {
    "tiger-cli": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",

      ],
      "env": {
        "TIGER_PUBLIC_KEY": "your-value",
        "TIGER_SECRET_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add tiger-cli --env TIGER_PUBLIC_KEY=your-value --env TIGER_SECRET_KEY=your-value -- docker run -i --rm -e TIGER_PUBLIC_KEY -e TIGER_SECRET_KEY ghcr.io/timescale/tiger-cli:0.27.0

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

Common questions

Is Tiger MCP 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?

You need to fill in: TIGER_PUBLIC_KEY, TIGER_SECRET_KEY

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 (0.27.0) reached the registry 10 days ago.

Which apps can use it?

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

What can I use instead?

After installing Tiger CLI, authenticate with your Tiger Cloud account:

# Login to your Tiger account

tiger auth login

View available commands

tiger --help

List your database services

tiger service list

Create a new database service

tiger service create --name my-database

Get connection string

tiger db uri

Connect to your database

tiger db psql

Run a query without psql

tiger db query -c "SELECT now()"

Install the MCP server

tiger mcp install

Install agent skills for your coding agent

tiger skills install

Use tiger --help for detailed information about each command, or browse the generated CLI reference.

Naming a Service

Anywhere a command takes a service as an argument, it takes either its ID (or a read replica set ID) or its name:

tiger db psql my-api-db

tiger service stop my-api-db

Names are matched exactly. A name that matches more than one service is refused; run tiger service list to find the ID you want. A default service (tiger config set service_id, --service-id, or TIGER_SERVICE_ID) must be an ID, and destructive commands still ask you to type the ID to confirm. The MCP tools take IDs only.

MCP Server

Tiger CLI includes a Model Context Protocol (MCP) server that enables AI assistants like Claude Code to interact with your Tiger Cloud infrastructure. The MCP server provides programmatic access to database services and operations.

Installation

Configure the MCP server for your AI assistant:

# Interactive installation (prompts for client selection)

tiger mcp install

Or specify your client directly

tiger mcp install claude-code # Claude Code tiger mcp install codex # Codex tiger mcp install copilot # GitHub Copilot CLI tiger mcp install cursor # Cursor IDE tiger mcp install devin # Devin tiger mcp install gemini # Gemini CLI tiger mcp install vscode # VS Code

After installation, restart your AI assistant to activate the Tiger MCP server.

Manual Installation

If your MCP client is not supported by tiger mcp install, follow the client's instructions for installing MCP servers. Use tiger mcp start as the command to start the MCP server. For example, many clients use a JSON file like the following:

{

"mcpServers": { "tiger": { "command": "tiger", "args": [ "mcp", "start" ] } } }

Streamable HTTP Protocol

The above instructions install the MCP server using the stdio transport. If you need to use the Streamable HTTP transport instead, you can start the server with tiger mcp start http --port 8080 and install it into your client using http://localhost:8080 as the URL.

Available MCP Tools

The MCP server exposes the following tools to AI assistants:

Service Management:

  • service_list - List all database services in your project
  • service_get - Get detailed information about a specific service
  • service_create - Create new database services with configurable resources
  • service_fork - Fork an existing database service to create an independent copy
  • service_start - Start a stopped database service
  • service_stop - Stop a running database service
  • service_rename - Rename a database service
  • service_resize - Resize a database service by changing CPU and memory allocation
  • service_delete - Permanently delete a database service (asks you to confirm first if the service is tagged PROD)
  • service_update_password - Set a new, randomly generated master password for a service (asks you to confirm first if the service is tagged PROD)
  • service_logs - View logs for a database service

Service Metrics:

  • service_metrics_available - List the metric names available for a service (hardware usage, PostgreSQL settings and activity, PgBouncer pools, TimescaleDB internals)
  • service_metrics_details - Show a metric's description, type, default aggregation and labels
  • service_metrics_series - Fetch a metric's time series over a time window, with label filters, an aggregation function, group by and bucket size

Database Operations:

  • db_query - Execute SQL queries against a database service, passed inline or as a path to a SQL file, with support for parameterized queries, custom timeouts, and connection pooling
  • db_schema - Display a service's database schema (tables, views, materialized views, enums, functions, procedures, indexes, triggers, and TimescaleDB hypertable/continuous aggregate metadata) as readable text for an agent's context
  • db_extensions_list - List the PostgreSQL extensions installed in a service database, with each extension's version, schema, and description

Feedback:

  • feedback - Submit feedback or a bug report to the Tiger Data team

The MCP server automatically uses your CLI authentication and configuration, so no additional setup is required beyond tiger auth login.

Proxied Tools

In addition to the service management tools listed above, the Tiger MCP server also proxies tools from a remote documentation MCP server. This feature provides AI assistants with semantic search capabilities for PostgreSQL, TimescaleDB, and Tiger Cloud documentation, as well as prompts/guides for various Tiger Cloud features.

The proxied documentation server (pg-aiguide) currently provides the following tools:

  • view_skill - Retrieve comprehensive guides for Postgres and TimescaleDB features and best practices
  • search_docs - Search PostgreSQL and TimescaleDB documentation using natural language queries

This proxy connection is enabled by default and requires no additional configuration.

To disable the documentation proxy:

tiger config set docs_mcp false

Agent Skills

Tiger CLI can install curated PostgreSQL and TimescaleDB skills directly into your coding agents:

# Interactive installation (prompts for install locations)

tiger skills install

Or name the locations directly

tiger skills install universal claude-code

Skills are installed for the current user. The universal location, ~/.agents/skills, is read by most coding agents (Cursor, Codex, Gemini CLI, VS Code, GitHub Copilot CLI, Devin). Claude Code, Kiro CLI, and Google Antigravity read their own skills directories, so they're separate locations (claude-code, kiro-cli, antigravity). Naming a client that reads ~/.agents/skills, such as cursor, selects universal. Use --skills-dir to install into a directory of
