What is stock-mcp-query?

A tool for querying historical stock-market data, including prices, company financial reports, ETFs, and market indexes. It connects to a stock database through a standard tool interface and requires a paid access token.

Use it to retrieve daily price data, financial statements, market indicators, stock screens, ETF data, and index data for Chinese and Hong Kong markets.

It removes the need to collect and format large amounts of past market data manually. Without the required token and server setup, it cannot query the database.

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Rogue Agent · line 42
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00076	$0.01105
Opus 5	$0.00038	$0.00553
Sonnet 5	$0.00015	$0.00221
Haiku 4.5	$0.00008	$0.00111

Security

Grade A, and why

stock-mcp-query scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Stock MCP Query

Query historical stock market data including daily OHLCV, financial reports, index data, ETF data, and more through the MCP protocol.

Prerequisites

This skill requires:

STOCK_MCP_TOKEN environment variable — a JWT token purchased from the management platform (nps_enhanced)
STOCK_MCP_SERVER_URL environment variable (optional) — the MCP server URL, defaults to the URL provided at purchase time

Setup Check

Before using any data query tools, verify the environment is configured:

# Check if token exists
echo ${STOCK_MCP_TOKEN:+Token is set}${STOCK_MCP_TOKEN:-ERROR: STOCK_MCP_TOKEN not set}

If STOCK_MCP_TOKEN is not set:

Visit the management platform (nps_enhanced web panel)
Navigate to "MCP Data Query" subscription page
Purchase a query quota pack (e.g., 10k records for 10 CNY)
Copy the issued token

Set the environment variable:

export STOCK_MCP_TOKEN="eyJ..."
export STOCK_MCP_SERVER_URL="https://your-node:8001/messages"

DeepSeek Harness

When running inside DeepSeek Harness (dsh), do not call the raw plugin tools. Use:

mcp__stock__stock_list_tools — category is one of market|basic|financial|index|etf|hk|realtime|toplist|other; query is a keyword such as daily or a ts_code prefix.
mcp__stock__stock_call_tool — tool_name must be a name returned by the list tool (example: tushare_daily_get_daily_data); arguments is a JSON object matching that tool's inputSchema.

Keep queries narrow (one ts_code / code and a short date range). Results are truncated.

Start dsh with this repo's overlay instead of pointing at localhost:8001/messages:

export STOCK_DATASOURCE_ROOT=/absolute/path/to/stock_datasource
dsh web --patch "$STOCK_DATASOURCE_ROOT/integrations/dsh/stock.cordis.yml"

Stdio MCP spawned by dsh does not use STOCK_MCP_TOKEN.
