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.

Quick start (≈ 2 minutes)

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

Add this block to your Claude Desktop config file:

config.json

{
  "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

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).

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/).
