Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

science-ai-mcp-server

Model Context Protocol server for Science AI Journal tools. Use Pre-Check, AI Review, Research Gaps, Journal Recommender, Duplicate Publication Checker, and the Article Writer from inside Claude Desktop, Cursor, Cline, or any MCP-enabled client — without leaving your assistant.

Full docs and screenshots: https://scienceaijournal.com/developers/mcp

Quick start (≈ 2 minutes)

  1. Generate an API key at https://scienceaijournal.com/settings?section=api-keys (free account required). Copy the saij_… token — you only see it once.

  2. Add this block to your Claude Desktop config file:

    {
      "mcpServers": {
        "science-ai-journal": {
          "command": "npx",
          "args": ["-y", "science-ai-mcp-server"],
          "env": {
            "SCIENCE_AI_API_KEY": "saij_…paste your key…"
          }
        }
      }
    }

    Config file locations:

    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: %APPDATA%\Claude\claude_desktop_config.json
    • Linux: ~/.config/Claude/claude_desktop_config.json
  3. Restart Claude Desktop. The science-ai-journal server appears in the 🔌 tool list.

The same config works in Cursor (~/.cursor/mcp.json), Cline (via the VS Code extension panel), and Continue (anywhere that supports an mcpServers object).

Tools

| Tool | What it does | Cost | | --- | --- | --- | | pre_check_paper | Tier 1-5 acceptance probability from title + abstract (local FTS5, no LLM) | Free | | check_duplicate_publication | Cross-reference against CrossRef + arXiv + medRxiv + bioRxiv + Unpaywall + a 900k-paper library | Free | | recommend_journals | Ranked target journals from a 1,214-venue index, with predatory-journal flags | Free | | find_research_gaps | Synthesised gaps + most-cited + most-recent papers around your query | Credits | | ai_review_paper | Single-agent AI peer-review pass on a prepared prompt | Credits | | start_writer_pipeline / get_writer_pipeline_status | Drive the Article Writer pipeline from outside the wizard | Credits |

Configuration

| Env var | Default | Purpose | | --- | --- | --- | | SCIENCE_AI_API_KEY | required | Your saij_… token | | SCIENCE_AI_BASE_URL | https://scienceaijournal.com | Override for self-hosted or staging environments |

Troubleshooting

  • Tools don't appear after editing config: fully quit the host app (not just close the window) and reopen.
  • 401 unauthorized when calling a tool: the key was wrong, revoked, or expired. Mint a fresh one at Settings → API Keys.
  • 429 rate limit on find_research_gaps: you hit the 10-per-hour IP quota. Wait an hour.
  • npx can't resolve the package: ensure Node ≥ 20 and that your npm registry isn't set to a private mirror without this package yet (npm config set registry https://registry.npmjs.org/).
