Webull Tools & Capabilities (71)
Tool names from Anthropic's directory listing. This server requires sign-in, so we could not read tool descriptions or parameter schemas.
Limits
- This connector is not a trading interface, on the evidence available. Webull's four documented Cloud MCP capability groups are all read permissions, and no tool name in the directory places, cancels or modifies an order. Treat it as read and research access to a brokerage account.
- Webull's own Local MCP does place orders — do not confuse the two. The separate Local MCP server documents
place_stock_order,place_option_single_order,place_futures_order,place_crypto_order,place_algo_order,replace_stock_orderandcancel_order, among others, plus order-notional and quantity caps and a symbol whitelist. That is different software with different credentials, and it is not the connector listed in Anthropic's directory. - Webull states its MCP output is not investment advice. Its Local MCP disclosure says the server provides information "solely for reference purposes" and does not constitute investment advice, that trading carries substantial risk of loss, and that all trading decisions are the user's own. Listing this connector is not an endorsement of any financial action.
- Two tools are undocumented.
get_stock_noii_snapshotandget_stock_noii_barsappear in Anthropic's directory but not in Webull's endpoint table, so we cannot say what they return. - Tool parameters and safety annotations were not readable. The endpoint returned HTTP 401 on 2026-08-16, so we read names from the directory and meanings from Webull's docs. No tool was called.
- Account and market coverage depend on what you authorize. Accounts you do not select and capability groups you do not approve are unreachable, so a missing balance is usually a consent scope, not a fault.
- Rate limits are documented for the OpenAPI, not for Cloud MCP. Webull publishes application- level limits per
app_keywith HTTP 429 on exceedance, expressed as requests per time window. Cloud MCP uses OAuth rather than anapp_key, and no MCP-specific limit is published.
Frequently asked questions
Can the Webull MCP server place trades for you?
No. Webull's Cloud MCP documentation lists four capability groups — Account Infos, Order Query, Market Data and Security Master — and all four are described as view or access permissions. None of the 71 tool names in Anthropic's directory begins with place, cancel or replace, so the hosted connector reads your account and the market rather than acting on it.
What is the difference between Webull Cloud MCP and Local MCP?
Cloud MCP is the hosted connector in Anthropic's directory, and Webull describes it as fully managed with OAuth sign-in and no local install. Local MCP is separate software you run yourself with an App Key and App Secret, and its documented tool table does include order placement. Only Cloud MCP is covered by this page.
Which parts of your Webull account does the connector see?
Only the accounts and capabilities you tick during authorization. Webull's docs describe a unified authorization page where you select individual accounts — cash, margin, IRA or futures — and independently approve capability groups, stating that only explicitly authorized capabilities reach the AI platform. Webull calls this the Principle of Least Privilege.
Do you need a paid Webull API plan to use the connector?
Webull does not publish a plan requirement for Cloud MCP. Its general OpenAPI FAQ states there are no extra charges for API access and that trading fees match the Webull app, while noting advanced market data subscriptions are bought separately. Whether those subscriptions gate specific Cloud MCP quotes is not documented.
How do you connect Webull MCP to Claude or ChatGPT?
Add the endpoint as a remote connector, then complete Webull's OAuth sign-in. Webull documents Cloud MCP working in Claude, ChatGPT and Grok, and publishes setup notes for Codex, Cursor, Kiro, Zed and Cherry Studio. Sign-in accepts a mobile number or email, plus your password and trading password.
