Quotes and fundamentals are the easy half; the account, portfolio and order-routing tools are the half most market servers stop short of. What an agent can do is bounded entirely by your own credentials, because the server holds none of its own.
Longbridge's own server for its brokerage, hosted at https://mcp.longbridge.com over Streamable HTTP. It is stateless: every request forwards your bearer token straight to the Longbridge SDK, with nothing stored server-side.
- 163 tools in twenty categories, covering US and HK markets
- Quote (32) — real-time and historical quotes, candlesticks, depth, brokers, options, warrants, watchlists, capital flow, short positions
- Fundamental (33) — statements and reports, business segments, institutional views, industry peers, dividends, EPS forecasts, valuations, shareholders, corporate actions
- Trade (14) — order submission, cancellation and replacement, positions, balance, executions, cash flow, margin
- DCA (9) and Grid (11) — dollar-cost-averaging plans and grid-trading orders, each with their own lifecycle and history reads
- Market (15), IPO (7), Screener (5), Alert (5) and Portfolio (4) — market status and rankings, IPO calendar and subscriptions, screener strategies, price alerts, profit-and-loss analysis
A Longbridge account. Point a Streamable HTTP client at https://mcp.longbridge.com and complete OAuth 2.1 — authorization is discovered from the endpoint, so there is no token to paste. Self-hosting runs the ghcr.io/longbridge/longbridge-mcp image; set --base-url to the externally reachable URL, since the default localhost value is not reachable by remote clients.
One command — claude mcp add --transport http longbridge https://mcp.longbridge.com
