Your AI's research copilot.

Your AI Googles when you say "research." Paper Pilot actually searches real academic databases, downloads the PDFs, reads them cover to cover, and gives you evidence with citations.

uvx paper-pilot

That's it. Or install it:

pip install paper-pilot

graph LR
    A[Prompt] --> B[Search 6 databases]
    B --> C[Resolve OA PDFs]
    C --> D[Download & read]
    D --> E[Extract evidence]
    E --> F[Render figures]
    F --> G[Markdown report]
    G --> H[Zotero sync]

One prompt. Six academic databases. Real PDFs. Real citations.

Research retrieval-augmented generation, deep-read the top papers, and compare the methods.

Your AI will:

1. Search Semantic Scholar, OpenAlex, arXiv, Crossref, and Europe PMC
2. Find the open-access PDFs, not just abstracts
3. Download and read them cover to cover
4. Extract evidence chunks with source attribution
5. Render specific pages so it can see the figures and tables
6. Write a structured Markdown report
7. Save everything into your Zotero library

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "paper-pilot": {
      "command": "uv",
      "args": ["--directory", "/path/to/paper-pilot", "run", "paper-pilot"],
      "env": {
        "OPENALEX_EMAIL": "you@example.com",
        "UNPAYWALL_EMAIL": "you@example.com",
        "ZOTERO_LOCAL": "true",
        "SCIHUB_ENABLED": "false"
      }
    }
  }
}

claude mcp add --scope user paper-pilot -- uv --directory /path/to/paper-pilot run paper-pilot

Add to ~/.codex/config.toml:

[mcp_servers.paper_pilot]
command = "uv"
args = ["--directory", "/path/to/paper-pilot", "run", "paper-pilot"]

[mcp_servers.paper_pilot.env]
OPENALEX_EMAIL = "you@example.com"
ZOTERO_LOCAL = "true"

paper-pilot --transport streamable-http --host 127.0.0.1 --port 8000

Sci-Hub access is disabled by default. To opt in:

SCIHUB_ENABLED=true

Once enabled, use search_scihub and download_scihub_paper directly, or pass include_scihub=True to research_topic / deep_read_topic for automatic fallback.

Disclaimer: Sci-Hub integration is provided strictly for educational and research purposes. Users are solely responsible for compliance with applicable laws and institutional policies.

PhD students that don't want to spend a week on a literature review. Point it at your thesis topic, get back a structured comparison with real citations and the PDFs already in Zotero.

Research labs that want to scan preprints weekly and auto-file them. Run research_topic on a schedule and keep your group library current.

AI builders that need their agents to work with real academic papers instead of web scraping snippets.
