Provides tools to search and retrieve preprints in the fields of computer science, mathematics, and physics from the arXiv repository.
Enables DOI lookups and journal metadata retrieval across over 150 million records via CrossRef.
Allows searching and retrieving biomedical literature and research records from the PubMed database.
Enables searching for computer science, social science, and interdisciplinary research papers through the Semantic Scholar platform.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@paper-search-mcpFind recent papers about large language models on arXiv"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
paper-search-mcp
Academic paper search MCP server for Cloudflare Workers, designed for deployment via mcp-deploy.
Searches across multiple platforms:
Semantic Scholar — CS, social science, interdisciplinary research
CrossRef — 150M+ records, DOI lookups, journal metadata
arXiv — CS, math, physics preprints
PubMed — biomedical literature
bioRxiv / medRxiv — biology and medical preprints
How it works
This repo contains only MCP logic. Auth, deployment, and UI are handled by mcp-deploy. The repo ships:
src/— MCP server code (Cloudflare Workers + Durable Objects)mcp-deploy.json— deployment contract (secrets, config, worker settings)
Local development
Release
Tag a version to trigger the GitHub Actions release workflow:
This builds worker.mjs and publishes it alongside mcp-deploy.json as release assets. mcp-deploy fetches these assets to deploy the worker.
Testing
Integration tests hit live APIs. Set .dev.vars with optional API keys for better rate limits:
