Timescale's Tiger CLI is a free Model Context Protocol (MCP) server built with Go, designed for the mcp platform. It extends programmatic access to database services and operations for AI assistants and developers. This tool connects to Tiger Cloud and PostgreSQL/TimescaleDB instances, acting as a bridge for AI clients. It also integrates remote documentation for semantic search, making it a valuable asset for managing and interacting with database systems through AI.

What does Tiger CLI connect to?

Tiger CLI functions as an MCP server, linking to Tiger Cloud and PostgreSQL/TimescaleDB instances. It provides programmatic access to database services and operations on these platforms. Additionally, it proxies tools from a remote documentation MCP server, pg-aiguide. This connection enables semantic search capabilities across documentation for PostgreSQL, TimescaleDB, and Tiger Cloud, enhancing its utility for AI assistants working with these database technologies.

Core features and tools

Tiger CLI exposes direct Tiger tools for service management and database operations, mirroring tiger CLI commands like service_list and service_create. It also offers proxied documentation tools: view_skill, which retrieves guides for Postgres and TimescaleDB features, and search_docs, for natural language queries against PostgreSQL and TimescaleDB documentation. The server provides programmatic access to database services and operations, making it a versatile interface.

Who is it for?

Tiger CLI is intended for coding agents, AI assistants, scripts, and developers who need programmatic interaction with database services. It supports AI assistants in writing production-level Postgres code and performing semantic searches on database documentation. This tool is ideal for those automating database management or integrating AI into their development workflows. Skip this if you do not use AI assistants or scripts for database management and documentation search.

How to get started

Access is granted through a standard OAuth authorization flow. Setup involves running "tiger auth login", which opens a browser for sign-in. For non-interactive sessions, client credentials can be used. The server supports the stdio transport protocol by default, and also Streamable HTTP, which can be started with "tiger mcp start http --port 8080".

Use cases

• Managing and querying database services in Tiger Cloud programmatically.
• Helping coding agents write production-level Postgres code.
• Enabling AI assistants to perform semantic search over PostgreSQL, TimescaleDB, and Tiger Cloud documentation.

Tiger CLI offers a powerful interface for AI assistants and developers to manage database services and access documentation. Its ability to connect to Tiger Cloud, PostgreSQL, and TimescaleDB, combined with semantic search, makes it a valuable tool for modern development workflows. The support for both stdio and Streamable HTTP transports broadens its applicability for various AI clients.
