Claude Research Gateway

Claude Research Gateway 🔬

An MCP (Model Context Protocol) server that enables Claude to access paywalled scientific papers through your institutional login (Shibboleth/SAML SSO, EZProxy).

How it works: When you ask Claude to find or read a paper, this tool authenticates to journal portals using your university credentials (via a browser popup), then fetches the full text of papers you have institutional access to.

Supported Portals

| Portal | Key | Publisher | |--------|-----|-----------| | ACS Publications | acs | American Chemical Society | | SciFinder-n | scifinder | CAS | | ScienceDirect | elsevier | Elsevier | | Springer / Nature | springer | Springer Nature | | Wiley Online Library | wiley | Wiley | | IEEE Xplore | ieee | IEEE | | JSTOR | jstor | JSTOR | | PubMed Central | pmc | NIH / NLM |

Prerequisites

• Python 3.10+
• uv (Python package manager): pip install uv
• A valid institutional login (university SSO credentials)

Quick Setup

1. Install Dependencies

cd claude-tool-research
uv sync

2. Install Playwright Browsers

uv run playwright install chromium

3. Add to Claude Desktop

Edit your Claude Desktop config file:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Add this MCP server entry:

{
  "mcpServers": {
    "research-gateway": {
      "command": "uv",
      "args": [
        "--directory",
        "C:\\Users\\abdir\\Documents\\projects-code\\claude-tool-research",
        "run",
        "server.py"
      ]
    }
  }
}

4. Restart Claude Desktop

Close and reopen Claude Desktop. You should see the research tools appear in the tools menu (🔨 icon).

Usage Examples

First-Time Setup

You: "Configure my institution — I'm at MIT"
Claude: [Calls configure_institution with name="MIT", wayf_name="Massachusetts Institute of Technology"]

You: "Log me into ACS Publications"  
Claude: [Calls authenticate_portal("acs")]
→ A browser window opens → You complete your university SSO login → Session is saved

Searching Papers

You: "Search ACS for papers about lithium-ion battery cathodes published recently"
Claude: [Calls search_papers("acs", "lithium-ion battery cathode materials")]
→ Returns formatted search results with titles, authors, DOIs

Reading a Paper

You: "Fetch the full text of DOI 10.1021/jacs.3c12345"
Claude: [Calls fetch_paper("acs", doi="10.1021/jacs.3c12345")]
→ Downloads and extracts the full paper text for Claude to read and discuss

Checking Session

You: "Is my ACS session still active?"
Claude: [Calls check_session("acs")]
→ Reports session status and age

Available Tools

| Tool | Description | |------|-------------| | list_portals | Shows all portals and your login status for each | | authenticate_portal | Opens browser for institutional SSO login | | check_session | Verifies if a session is still valid | | search_papers | Searches for papers by keywords, title, etc. | | fetch_paper | Downloads and extracts full paper text (via DOI or URL) | | configure_institution | Sets up your institution name, EZProxy URL, WAYF name |

                                                   You enter your
                                                   credentials here

1. Claude calls authenticate_portal → a real browser window opens
2. The browser navigates to the publisher's institutional login
3. You're redirected to your university's SSO page (Shibboleth/SAML)
4. You enter your credentials in the browser
5. After successful login, the tool captures the session cookies
6. Cookies are encrypted and stored locally in ~/.claude-research/sessions/
7. Subsequent requests use these cookies — no browser needed until they expire

Security Notes

• No credentials stored: Only session cookies are saved, never your password
• Encrypted storage: Cookies are encrypted with a machine-local key (Fernet)
• Session expiry: Sessions follow your institution's expiry policy (typically 8–24h)
• Local only: All data stays on your machine in ~/.claude-research/

Configuration

Optional: create ~/.claude-research/config.json:

{
  "institution": {
    "name": "MIT",
    "ezproxy_url": "https://ezproxy.library.mit.edu/login",
    "wayf_institution_name": "Massachusetts Institute of Technology"
  },
  "rate_limit_seconds": 1.0,
  "max_content_length": 100000,
  "browser_timeout_seconds": 300
}

Troubleshooting

| Issue | Solution | |-------|----------| | Browser doesn't open | Run uv run playwright install chromium | | Login times out | Increase browser_timeout_seconds in config | | Session expired quickly | Your institution may have short session limits; re-authenticate | | Paper text is empty | Some publishers serve content via JavaScript — try the PDF version | | "Access denied" error | Re-authenticate with authenticate_portal |
