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: TypeScript SDK with automatic access-token caching and refresh
  • apps/mcp: local MCP server built on the SDK, with opt-in trading permissions

Requirements

  • Node.js 22.18 or later
  • pnpm

Setup

pnpm install
cp .env.example .env

Set TOSSCLIENTID and TOSSCLIENTSECRET in .env, then run:

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 and MCP setup guide for usage details.

Nothing above is checked by us. What we check is on the safety report.
