FirstData — Claude Code MCP server: source search and setup
FirstData helps an agent locate authoritative data sources from a natural-language query. Use it when you need primary evidence and a route back to the original material.
claude mcp add --transport http firstdata https://firstdata.deepminer.com.cn/mcpWhat FirstData does
The server matches a query to sources by subject, geography, time period and authority level. Results can include several recommendations with reasons, links to portals and APIs, data formats, and information about how to trace evidence. It can help locate official economic or financial statistics.
FirstData points to source material rather than returning ready-made numerical answers. The agent still needs to consult a recommended portal or API to retrieve or verify a figure. That distinction matters when your task requires the data itself, not a lead for further research.
Connect over HTTP to the hosted MCP server. In Claude Code, the command registers it as firstdata; Codex and Cursor can use the same server address in their MCP configuration.
What it helps with
- locate an official source for a requested statistic
- compare sources by authority and coverage
- trace a query to the original data
- find where a complex government portal keeps a dataset
Example prompts for the agent
- Find official sources for inflation data in the country I name.
- Locate primary sources on global trade for the requested period and explain how they differ.
- Find a government employment-data portal and show the path to its original records.
