ETF Fund Flow Anomalies

Problem

ETF fund-flow anomalies often appear in market feeds, news, or trading tools, but the data is fragmented and lacks a consistent interface. This skill wraps the GF Securities ETF Super Fund query into an MCP tool call, making it easier to retrieve anomaly results by conditions such as large inflow in scripts, automation pipelines, or agent workflows.

How It Works

The skill authenticates and calls a fixed endpoint:
- Configure GF_SKILLS_APIKEY; if the key is missing, the call should stop and prompt the user to request access from the GF skill market.
- Send a POST request to https://mcp-api.gf.com.cn/gf-skills/skills/mcp/call.
- Include service_name: etf-super-fund, tool_name: gfmiddle_eits_super_fund_etf_superfund_get, and query arguments such as args.type in the JSON body.
- Pass the API key via the Authorization: Bearer header, and avoid committing it to logs or repositories.

Boundaries

The provided material only shows the service name, tool name, authentication rule, and a large inflow example. It does not document the full response schema, pagination, historical ranges, or error codes. Validate the returned fields before using them in downstream analysis; this skill is suited for data retrieval and workflow integration, not as a final investment decision source without the relevant business context.
