Chakra MCP Server

[](https://badge.fury.io/py/chakra-mcp) [](LICENSE) [](https://pypi.org/project/chakra-mcp/)

A native integration with Anthropic's Model Context Protocol (MCP). Allows you to interact with your database and subscribed data shares using natural language.

• Data Share Interactions: Interact with subscribed data shares. For example, if you have subscribed to a financial data share, you can ask questions like "What is the stock price of Tesla?"
• Database Management: Create, update, and delete tables.

Installation

Automated Using OpenTools (Easier)

Install OpenTools prerequisites.

Then run:

npx opentools@latest i chakra

Manual Setup (More Work)

Add the following to your claude_desktop_config.json file:

• On MacOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json
• On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "chakra": {
      "command": "uvx",
      "args": ["chakra-mcp"],
      "env": {
        "db_session_key": "YOUR_DB_SESSION_KEY"
      }
    }
  }
}

Architecture

Disclaimers

• MCP is extremely early. The experience in Claude Desktop is suboptimal - every time you use the server, you have to grant access explicitly. This is a design decision on Anthropic's part and is not yet configurable.
• Setup is rough around the edges. We have worked closely with the folks at OpenTools to make this as seamless as possible, but there is room for improvement. We are looking forward to an MCP GUI experience in the future, but for now, users must use the command-line.
• Today, the server runs on the user's local machine. Anthropic's roadmap includes a hosted server option, which we will support. This will make authentication, setup, and performance much better.
