# Toss Securities Open API > Unofficial community project. This project is not affiliated with or endorsed by Toss Securities. pnpm workspace for a TypeScript SDK and a local MCP server for the Toss Securities Open API. The MCP server is read-only unless trading is explicitly enabled. ## Packages - [`packages/sdk`](packages/sdk): TypeScript SDK with automatic access-token caching and refresh - [`apps/mcp`](apps/mcp): local MCP server built on the SDK, with opt-in trading permissions ## Requirements - Node.js 22.18 or later - pnpm ## Setup ```sh pnpm install cp .env.example .env ``` Set `TOSS_CLIENT_ID` and `TOSS_CLIENT_SECRET` in `.env`, then run: ```sh pnpm check pnpm test pnpm test:live ``` The live test only performs read operations, and the MCP server defaults to read-only. See the [SDK guide](packages/sdk/README.md) and [MCP setup guide](apps/mcp/README.md) for usage details.
