Longbridge Security List

longbridge-security-list

Catalog lookups: US overnight-eligible securities, and the HK broker_id → name dictionary.

Response language: match the user's input language — Simplified Chinese / Traditional Chinese / English.

Subcommands

Run longbridge <subcommand> --help to confirm the current flag spelling and defaults.

⚠️ Scope: security-list only exposes the US Overnight category (full HK / A-share / SG catalogs are not available through this endpoint). The CLI returns Error: Only US market is supported for security-list ... if you pass HK / CN / SG. For non-US listed lookups, route the user to longbridge-quote for per-symbol queries.

When to use

• "美股 overnight 哪些股票", "US overnight tradable count" → security-list
• "经纪商 ID 9000 是谁", "broker 0001" → participants
• "翻译一下经纪商列表" → participants
• "港股 / A 股一共多少只", "list of HK / CN stocks" → not in scope; explain the scope limit and offer per-symbol lookup via longbridge-quote.

Usage rules

• For "how many" questions, reply with the array length; do not dump the full payload.
• For broker_id translation, find the matching row instead of dumping the whole directory.
• For "list all stocks" requests in non-US markets, ask the user to narrow scope (industry, name search) and route them to longbridge-quote.

CLI

longbridge security-list      --format json
longbridge participants       --format json

Output

• security-list: array of {symbol, name_en, name_cn} for US overnight-eligible names.
• participants: array of {broker_id, name_en, name_cn} for HK brokers.

Error handling

If longbridge is missing, fall back to MCP. If stderr says "Only US market is supported for security-list" on a non-US market query, explain the scope limit to the user and offer per-symbol lookup via longbridge-quote. Other stderr messages relay verbatim.

MCP fallback

When the CLI is unavailable, fall back to the MCP server. Discover available tools from the MCP server's tool list at runtime — do not rely on hardcoded tool names.
