# PaperPilot ∢

**Research superpowers for AI agents.** One MCP server gives any agent instant arXiv + PubMed access with citation-grade extraction.

No scraping. No ads. Wraps the free arXiv and NCBI E-utilities APIs — zero backend risk, zero per-call cost.

## Live verification

Tested against both upstream APIs (real responses, this machine):

```
search_arxiv("CRISPR gene editing", 2)
→ "Primer on the Gene Ontology", Gaudet et al. — https://arxiv.org/pdf/1602.01876v1

search_pubmed("sickle cell CRISPR", 1)
→ JCO Oncol Pract. 2026 Aug 19:OP2600479 — "Translating CRISPR to Practice in the Clinic…"
```

## Install (30 seconds)

Requires Python ≥ 3.10 and `mcp>=1.2,<1.10` (1.9.4 verified).

```bash
python3.11 -m venv .venv && . .venv/bin/activate
pip install "mcp>=1.2,<1.10"
```

Add to your Claude / Hermes / Cursor / Codex MCP config:

```json
{
  "mcpServers": {
    "paperpilot": {
      "command": "/path/to/.venv/bin/python",
      "args": ["/path/to/paperpilot/server.py"]
    }
  }
}
```

Then ask your agent: *"Find recent papers on protein folding with diffusion models and cite them."* It calls PaperPilot.

## Why agent-native?

In the agentic era discovery happens *through* agents. Whoever the agent reaches for wins. PaperPilot is built to be the tool agents reach for when they need research.
