Webull MCP vs moomoo MCP

Side-by-side facts with sources, last checked 2026-10-16.

Verdict: Both are hosted MCP servers with OAuth sign-in and no API keys. The big difference is order handling: Webull's trading tools only create order instructions that you must confirm in the Webull app or desktop, while moomoo's trade:write scope lets the AI submit and cancel orders directly (moomoo warns these use real funds).

Connect from Claude Code

# moomoo (command from moomoo's Quick Start)
claude mcp add moomoo-mcp --transport http https://mcp.moomoo.com/mcp

# Webull (Webull documents the URL; this is Claude Code's standard remote-server syntax)
claude mcp add --transport http webull https://api.webull.com/mcp

Codex (from Webull's docs): codex mcp add webull --url https://api.webull.com/mcp. Cursor: add the URL as a remote MCP server; moomoo's docs show .cursor/mcp.json with {"mcpServers":{"moomoo-mcp":{"url":"https://mcp.moomoo.com/mcp"}}}.

Which to pick

Want a human in the loop for every order? Webull's design makes the app confirmation mandatory for every instruction.
Want the agent to execute on its own? moomoo allows direct submit/cancel once you grant trade:write. Start with quote:read and trade:read only, as moomoo recommends.
Need HK, CN, SG, JP or MY markets? Our moomoo listing covers those OpenAPI markets; check what your account and region allow (moomoo notes some tools may be limited by account tier or region).

FAQ

Can Webull's MCP place trades without my confirmation?

No. Webull's trading tools create order instructions that require confirmation in the Webull app or desktop, and you can revoke pending instructions.

Can moomoo's MCP place trades directly?

Yes, if you grant the trade:write scope during OAuth (and supply your trade password). moomoo recommends starting with read-only queries and warns trading uses real funds.

Do I need an API key for either?

No. Both use OAuth sign-in through your AI client: Webull uses an authorization code flow, moomoo uses OAuth 2.1.

How do I revoke access?

moomoo: invalidate tokens from the dashboard. Webull: you choose accounts and capability groups at authorization, and pending order instructions can be revoked.
