FAQ from Schwab MCP Server
Is this an official Charles Schwab product?
No, it is an unofficial, community-developed MCP server. It has not been approved, endorsed, or certified by Charles Schwab. Use at your own risk.
What are the runtime requirements?
Node.js 22.x or higher, a Cloudflare account (paid plan for Durable Objects), Wrangler CLI, and a Schwab Developer account with a registered app. A KV namespace is also needed for OAuth token storage.
Where is my data stored?
OAuth tokens are stored in Cloudflare KV with 31‑day TTL. Session state uses Durable Objects. Schwab API responses are delivered on demand and not persisted by the server.
What are the known limitations?
Order management (cancel, place, replace) is marked as experimental. Durable Objects require a paid Cloudflare Workers plan. The server may be incomplete or unstable. No official support from Schwab.
What transport protocol does it use?
The server communicates via Server‑Sent Events (SSE). Authentication uses OAuth 2.0 with PKCE, with a browser flow for initial authorization.
