<summary>Setting up with Docker</summary>
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": "<YOUR KALSHI API KEY>",
"BASE_URL": "https://api.elections.kalshi.com"
}
}
}
```
</details>
## 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

### 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",
"/<path to repo root directory>",
"run",
"start"
],
"env": {
"KALSHI_PRIVATE_KEY_PATH": "PATH TO YOUR RSA KEY FILE",
"KALSHI_API_KEY": "<YOUR KALSHI API KEY>",
"BASE_URL": "https://api.elections.kalshi.com"
