Skills vs MCP

Skills · skills/

Agent instructions

Markdown workflows the agent reads — Stata, LaTeX, writing, data viz. No credentials.

  • Copy folder → ~/.cursor/skills/
  • e.g. stata-regression, econ-humanizer

MCP · mcp/

Live data connections

Servers the agent calls as tools — WRDS, SEC EDGAR, OpenEcon macro data, and more.

  • pip install / uvx + MCP config + credentials
  • e.g. wrds-mcp, sec-edgar-mcp, OpenEcon Data

Not sure which of the two you need for a given task? The pipeline guide walks the nine steps of an empirical project in order and names the skills and MCP servers for each one.
