# MCP Server Kalshi This is an MCP server for the Kalshi REST API ## Configuration ### Claud Desktop

Setting up with UVX

```json "mcpServers": { "kalshi": { "command": "uvx", "args": ["mcp-server-kalshi"], "env": { "KALSHI_PRIVATE_KEY_PATH": "PATH TO YOUR RSA KEY FILE", "KALSHI_API_KEY": "", "BASE_URL": "https://api.elections.kalshi.com" } } } ```

Setting up with Docker

1. Build the container from root directory `docker build -t mcp-server-kalshi .` 2. Configure client to run the container (ensure the bind command gives the container access to your rsa key files) ```json "mcpServers": { "kalshi": { "command": "docker", "args": ["run", "--rm", "-i", "--mount", "type=bind,src=/Users/username,dst=/Users/username", "-e", "KALSHI_PRIVATE_KEY_PATH", "-e", "KALSHI_API_KEY","-e", "BASE_URL", "mcp-server-kalshi"], "env": { "KALSHI_PRIVATE_KEY_PATH": "PATH TO YOUR RSA KEY FILE", "KALSHI_API_KEY": "", "BASE_URL": "https://api.elections.kalshi.com" } } } ```

## Local Development 1. Create a `.env` file in the root directory with the following variables * `BASE_URL` The kalshi API URL * `KALSHI_API_KEY` The API key for the corresponding environment * `KALSHI_PRIVATE_KEY_PATH` A filepath to a file containing your Kalshi RSA private key 2. Install deps via `uv pip install -e .` Dev deps can be installed with `uv pip install -e .[dev]` 3. Run with `uv run start` ### Getting Kalshi API Creds To get Kalshi API creds, follow the instrictions [here](https://trading-api.readme.io/reference/api-keys) ### Getting a Test Account You may want to run the server against a kalshi demo account. To get an account, follow the instructions [here](https://trading-api.readme.io/reference/creating-a-demo-account) Then, set `BASE_URL=https://demo-api.kalshi.co` for this MCP server and update your `KALSHI_API_KEY` and `KALSHI_PRIVATE_KEY_PATH` to point towards credentials generated in the testing environment ### UVX To run in MCP inspector ```bash npx @modelcontextprotocol/inspector uv --directory /path/to/your/mcp-server-kalshi run start ``` To run in claud desktop, update your MCP config to: ```json { "mcpServers": { "kalshi": { "command": "uv", "args": [ "--directory", "/", "run", "start" ], "env": { "KALSHI_PRIVATE_KEY_PATH": "PATH TO YOUR RSA KEY FILE", "KALSHI_API_KEY": "", "BASE_URL": "https://api.elections.kalshi.com" } } } } ```
