Features

• Search NBER working papers by title, paper number, author, abstract, or keyword.
• Fetch structured metadata and abstracts for a paper ID such as w25000.
• Download single papers or batches as PDF files.
• Expose the same core workflows as MCP tools for AI agents.
• Return human-readable output by default, with JSON output for automation.

Quick Start

Use in Agents

NBER-CLI can be used by agents through plugins, the MCP server, and the skill. Claude Code and Codex should install the NBER-CLI plugin first; OpenClaw and other agents should use the MCP server plus the skill.

If you want an agent to install and check NBER-CLI automatically, send it this prompt:

Install NBER-CLI globally for yourself from https://github.com/sepinetam/nber-cli, and check the status.

After installation, verify it with either prompt:

I remember that in 2025, Anton had a paper on NBER about Agent for Econ. Download it to the current directory.

I remember that paper w25000 was interesting. Show me its abstract.

If you are an agent, visit the Agent Guides.

CLI Mode

Run commands directly with uvx:

uvx nber-cli search "Labor Economic"
uvx nber-cli info w25000
uvx nber-cli download w34567

Or install the command first:

uv tool install nber-cli
nber-cli search "Labor Economic"
nber-cli info w25000
nber-cli download w34567

MCP Server Mode

NBER-CLI can run as a stdio MCP server:

uvx nber-cli mcp-server

Example MCP client configuration:

{
  "mcpServers": {
    "nber-cli-mcp": {
      "command": "uvx",
      "args": ["nber-cli", "mcp-server"]
    }
  }
}

The MCP server exposes tools for paper lookup, search, and PDF download.
