Wudao MCP Server

Wudao A-Share Stock Data MCP

Wudao A-Share Stock Data MCP (悟道 A股股票数据 MCP) is a remote HTTP MCP server for China A-share market data. It serves 63 tools to AI agents: 57 read-only query tools and 6 tools that manage the caller's own watchlist. It does not place trades.

It is maintained by 杭州瞬微网络科技有限公司 (QuickTiny) and shares accounts with 连板天梯. The facts below were checked against the live manifest on 2026-10-06; the manifest and tools/list are authoritative.

• Endpoint: https://stock.quicktiny.cn/api/mcp (Streamable HTTP, stateless JSON-RPC over POST; no stdio)
• Auth: Authorization: Bearer YOUR_API_KEY, with a key from the developer console; gateways that reserve Authorization (for example Smithery) can send the same key as X-API-Key: YOUR_API_KEY
• Manifest: https://stock.quicktiny.cn/api/mcp/manifest
• Docs: client setup · tool catalog · pricing and limits · product facts
• Not affiliated with Tushare

Quick start

Claude Code:

claude mcp add --transport http wudao https://stock.quicktiny.cn/api/mcp --header "Authorization: Bearer YOUR_API_KEY"

Codex CLI:

export WUDAO_API_KEY=YOUR_API_KEY
codex mcp add wudao --url https://stock.quicktiny.cn/api/mcp --bearer-token-env-var WUDAO_API_KEY

Cursor, WorkBuddy and other clients configured with JSON:

{
  "mcpServers": {
    "wudao-stock-data": {
      "url": "https://stock.quicktiny.cn/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Coze (扣子): in the resource library create a plugin, set the type to MCP and the plugin URL to https://stock.quicktiny.cn/api/mcp. Choose authorization Service token / API key, location Header, parameter name X-API-Key, and paste your key as the value. Confirming imports the tools; publishing keeps the plugin inside your own workspace. Step-by-step: Coze guide.

Then ask the agent to call trading_calendar with date="2026-09-04"; it should return isTradingDay: true.

Tested on 2026-10-06 with Claude Code 2.1.284: tool discovery, trading_calendar and limit_up_ladder returned structured results. Tested on 2026-10-08 in Coze: the MCP plugin imported the tools and a trading_calendar trial run returned data. The Codex command follows codex mcp add --help in Codex CLI 0.130.0. Other clients use the standard remote HTTP configuration and were not each tested end to end. WorkBuddy steps: WorkBuddy guide.

Pricing and limits

Each tools/call counts once, workflow tools included; initialize, tools/list and the manifest are free. Quota is per account across all keys and resets at 00:00 Beijing time. Prices are as of 2026-10-06; the purchase page is authoritative.

Profiles

One server with the default all profile is enough for most agents. To narrow the tool list, append ?profile= or send X-MCP-Profile: short_term, fundamental, market_replay, stock_research, theme_research, auction_review, personal, user, workflows, all.

https://stock.quicktiny.cn/api/mcp?profile=market_replay

Fit

Good fit: agents that run A-share post-market reviews (limit-up ladder, theme rotation, capital flow, Dragon Tiger List), opening-auction checks and event or risk calendars without building their own data tools.

Not a fit: long-horizon historical warehouses and factor research (Tushare or a local database), low-latency trading systems (broker or commercial market data APIs), research centred on global markets (for example Alpha Vantage), and anything that needs trade execution.

Evidence

• 2026-09-04 market review case with its public JSON
• Reproducible source check: maintainer-run, failed requests included; not an independent ranking
• Empty results, date mismatches and error states
• OpenClaw / Hermes review workflow

Directories

• Official MCP Registry: io.github.jcdreamjc/wudao-mcp
• ModelScope · Glama · LobeHub · MCP.so

Directory pages may lag; the manifest and this README are current.

Skill

skills/wudao-stock-data/SKILL.md explains when to use the server, how to configure it and how to pick tools for review tasks.

Wrapped config for marketplaces

Some marketplaces ask for a wrapped config object:

{
  "config": {
    "mcpServers": {
      "wudao-stock-data": {
        "url": "https://stock.quicktiny.cn/api/mcp",
        "headers": {
          "Authorization": "Bearer YOUR_API_KEY"
        },
        "params": {}
      }
    }
  }
}

Safety boundary

Read-only except the 6 watchlist tools, which change only the caller's own watchlist. No trade execution, investment advice or return promises.
