CI PyPI version Python 3.12+ License: MIT

GHCR

MCP server for interdisciplinary and transdisciplinary AI-assisted research — paper ingestion, semantic search across literature, citation graph traversal, cross-domain knowledge synthesis, and research workflow automation

Built with FastMCP and mcp-refcache for efficient handling of large data in AI agent tools.

Features

• ✅ Reference-Based Caching - Return references instead of large data, reducing context window usage

• ✅ Preview Generation - Automatic previews for large results (sample, truncate, paginate strategies)

• ✅ Pagination - Navigate large datasets without loading everything at once

• ✅ Access Control - Separate user and agent permissions for sensitive data

• ✅ Private Computation - Let agents compute with values they cannot see

• ✅ Docker Ready - Production-ready containers with Python slim base image

• ✅ GitHub Actions - CI/CD with PyPI publishing and GHCR containers

• ✅ Langfuse Tracing - Built-in observability integration

• ✅ Type-Safe - Full type hints with Pydantic models

• ✅ Testing Ready - pytest with 73% coverage requirement

• ✅ Pre-commit Hooks - Ruff formatting and linting

Quick Start

Prerequisites

• Python 3.12+
• uv (recommended) or pip

Installation

# Clone the repository
git clone https://github.com/l4b4r4b4b4/science-mcp
cd science-mcp

# Install dependencies
uv sync

# Run the server (stdio mode for Claude Desktop)
uv run science-mcp

# Run the server (SSE/HTTP mode for deployment)
uv run science-mcp --transport sse --port 8000

Install from PyPI

# Run directly with uvx (no install needed)
uvx science-mcp stdio

# Or install globally
uv tool install science-mcp
science-mcp --help

Docker Deployment

# Pull and run from GHCR
docker pull ghcr.io/l4b4r4b4b4/science-mcp:latest
docker run -p 8000:8000 ghcr.io/l4b4r4b4b4/science-mcp:latest

# Or build locally with Docker Compose
docker compose up

# Build images manually
docker compose --profile build build base
docker compose build

Using with Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "science-mcp": {
      "command": "uv",
      "args": ["run", "science-mcp"],
      "cwd": "/path/to/science-mcp"
    }
  }
}

Using with Zed

The project includes .zed/settings.json pre-configured for MCP context servers.

uvx science-mcp stdio                          # Local CLI mode
uvx science-mcp sse --port 8000                # SSE on port 8000
uvx science-mcp streamable-http --host 0.0.0.0 # Docker/remote mode

CI/CD Workflow

This project uses a CI-gated workflow to ensure code quality and safe releases:

┌─────────────────────────────────────────────────────────────┐
│  Feature Branch → Open PR                                   │

│  CI Runs (lint, test, security)                            │
│         ↓                                                    │
│  ✅ CI Must Pass (enforced by branch protection)           │

│  Publish Workflow verifies Release succeeded                │
│         ↓                                                    │
│  Package Published to PyPI                                  │
└─────────────────────────────────────────────────────────────┘
                         ↓
┌─────────────────────────────────────────────────────────────┐
│  CD Workflow deploys (staging/production)                   │
└─────────────────────────────────────────────────────────────┘

Key Safeguards:

• ✅ Branch protection ensures CI passes before merge
• ✅ Tag pushes verify CI passed before building images
• ✅ Publish workflow verifies Release succeeded before PyPI upload
• ✅ CD workflow only deploys after Release completes

Manual Gates:

• 🔒 Creating GitHub Release (allows review before PyPI publish)
• 🔒 Production deployments (requires manual approval)

Publishing

PyPI

Configure trusted publisher at PyPI:

• Project name: science-mcp
• Owner: l4b4r4b4b4
• Repository: science-mcp
• Workflow: publish.yml
• Environment: pypi

Docker Images

Images are automatically published to GHCR on:

• Push to main branch → latest tag
• Version tags (v*.*.*) → latest, v0.0.1, 0.0.1, 0.0 tags
