academic-search-mcp-server

MCP.Pizza Chef: afrise

Three tools are on offer: a topic search with an optional year range, a general search, and a look-up of one paper by its identifier. Only the topic search returns what the notes promise. The general search asks Semantic Scholar for the wrong thing and silently drops every result from it, so you get bare Crossref entries with no abstracts. The look-up defaults to Semantic Scholar even though the notes say Crossref. No key is needed or accepted, and the free Semantic Scholar tier is often busy. Untouched since February 2025.

Academic Paper Search MCP Server

smithery badge

A Model Context Protocol (MCP) server that enables searching and retrieving academic paper information from multiple sources.

The server provides LLMs with:

  • Real-time academic paper search functionality
  • Access to paper metadata and abstracts
  • Ability to retrieve full-text content when available
  • Structured data responses following the MCP specification

While primarily designed for integration with Anthropic's Claude Desktop client, the MCP specification allows for potential compatibility with other AI models and clients that support tool/function calling capabilities (e.g. OpenAI's API).

Note: This software is under active development. Features and functionality are subject to change.

Setup

Installing via Smithery

To install Academic Paper Search Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @afrise/academic-search-mcp-server --client claude

note this method is largely untested, as their server seems to be having trouble. you can follow the standalone instructions until smithery gets fixed.

Installing via uv (manual install):

  1. Install dependencies:
uv add "mcp[cli]" httpx
  1. Set up required API keys in your environment or .env file:
#  These are not actually implemented
SEMANTIC_SCHOLAR_API_KEY=your_key_here 
CROSSREF_API_KEY=your_key_here  # Optional but recommended
  1. Run the server:
uv run server.py

Usage with Claude Desktop

  1. Add the server to your Claude Desktop configuration (claude_desktop_config.json):
{
  "mcpServers": {
    "academic-search": {
      "command": "uv",
      "args": ["run ", "/path/to/server/server.py"],
      "env": {
        "SEMANTIC_SCHOLAR_API_KEY": "your_key_here",
        "CROSSREF_API_KEY": "your_key_here"
      }
    }
  }
}
  1. Restart Claude Desktop

Development

This server is built using:

  • Python MCP SDK
  • FastMCP for simplified server implementation
  • httpx for API requests

API Sources

  • Semantic Scholar API

academic-search-mcp-server FAQ

Do I need an API key?
No, and it will not use one even if you set it. The setup notes list two key settings and then admit in a comment that neither is implemented, so every request goes out unregistered.
Which of the three searches should I use?
The topic search. It is the only one that comes back with abstracts and plain-language summaries. The general search quietly loses everything Semantic Scholar sends and leaves you with titles, authors, years and links.
Why do my searches keep coming back empty?
The free Semantic Scholar tier is shared and frequently answers with a too-many-requests refusal, which happened when this was checked. The server hides every failure behind one generic message, and because it cannot use a key, waiting is your only option.
Can I use this to read the full text of a paper?
No. Where a free copy exists you get a link to it, plus title, authors, year and abstract. Nothing is ever downloaded.
Does the Claude Desktop snippet in the notes work?
Watch for a stray space in the command it passes along, which some setups reject outright. Removing it fixes a mysterious startup failure.
Which apps does it work in?
Claude Desktop is the documented one. A Smithery install is listed, but the author says on the page that it is largely untested and their service was having trouble.
Is it still maintained?
It describes itself as under active development, but nothing has changed since February 2025, roughly a year and a half ago.
Can I use this at work?
It carries the AGPL version 3, the strictest of the common licences. If you build it into anything you offer to other people over a network, you have to publish your source too. Check with whoever handles licensing.
