Altmetric MCP Server

Model Context Protocol (MCP) server that enables AI agents to access Altmetric APIs for tracking the attention and reach of research outputs across news outlets, policy documents, social media, and other online platforms.

Altmetric monitors where research is being discussed beyond traditional academic citations - from mainstream media coverage to policy citations, patent references, and social media engagement - providing a comprehensive view of real-world research impact.

Prerequisites

• Node.js >= 20.6.0 - Download from nodejs.org (LTS recommended)
• Altmetric API credentials (at least one):
  • Details Page API key - Free tier or commercial access
  • Explorer API key + secret - Institutional access

Don't have keys yet? Request API access

Quick Install (Claude Desktop on macOS)

Run the guided installer in Terminal - it checks Node.js, prompts for your API keys, and configures Claude Desktop automatically:

bash <(curl -fsSL https://raw.githubusercontent.com/altmetric/altmetric-mcp/main/install.sh)

Or if you've cloned the repo:

bash install.sh

Prefer to set things up manually? See Claude Desktop below.

Installation

Configure your MCP client to run the Altmetric MCP server using npx. Include only the API credentials you have access to.

{
  "type": "stdio",
  "command": "npx",
  "args": ["-y", "altmetric-mcp"],
  "env": {
    "ALTMETRIC_DETAILS_API_KEY": "your_details_api_key_here",
    "ALTMETRIC_EXPLORER_API_KEY": "your_explorer_api_key_here",
    "ALTMETRIC_EXPLORER_API_SECRET": "your_explorer_api_secret_here"
  }
}

Below are specific instructions for popular AI tools and editors.

Claude Desktop

1. Open the configuration file at:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json

   On macOS you can open it from Terminal:

   mkdir -p ~/Library/Application\ Support/Claude && open -a TextEdit ~/Library/Application\ Support/Claude/claude_desktop_config.json

2. Add the Altmetric MCP server. If the file is empty, paste this (replacing the placeholder keys with your own, and removing any you don't have):

   {
     "mcpServers": {
       "Altmetric": {
         "type": "stdio",
         "command": "npx",
         "args": ["-y", "altmetric-mcp"],
         "env": {
           "ALTMETRIC_DETAILS_API_KEY": "your_details_api_key_here",
           "ALTMETRIC_EXPLORER_API_KEY": "your_explorer_api_key_here",
           "ALTMETRIC_EXPLORER_API_SECRET": "your_explorer_api_secret_here"
         }
       }
     }
   }

   If the file already has content, add "Altmetric": { ... } inside the existing "mcpServers" block, separated by a comma from the other entries.

3. Save the file and restart Claude Desktop (Cmd+Q then reopen).

4. Verify by asking Claude: "Use the Altmetric tools to look up the attention score for DOI 10.1038/nature12373"

Claude Code

Install directly from the command line:

claude mcp add --transport stdio altmetric-mcp \
  --env ALTMETRIC_DETAILS_API_KEY=your_details_api_key_here \
  --env ALTMETRIC_EXPLORER_API_KEY=your_explorer_api_key_here \
  --env ALTMETRIC_EXPLORER_API_SECRET=your_explorer_api_secret_here \
  -- npx -y altmetric-mcp

VS Code (GitHub Copilot)

Add to your project .vscode/mcp.json:

{
  "servers": {
    "Altmetric": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "altmetric-mcp"],
      "env": {
        "ALTMETRIC_DETAILS_API_KEY": "your_details_api_key_here",
        "ALTMETRIC_EXPLORER_API_KEY": "your_explorer_api_key_here",
        "ALTMETRIC_EXPLORER_API_SECRET": "your_explorer_api_secret_here"
      }
    }
  }
}

Reload VS Code to apply the changes. More information.

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "Altmetric": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "altmetric-mcp"],
      "env": {
        "ALTMETRIC_DETAILS_API_KEY": "your_details_api_key_here",
        "ALTMETRIC_EXPLORER_API_KEY": "your_explorer_api_key_here",
        "ALTMETRIC_EXPLORER_API_SECRET": "your_explorer_api_secret_here"
      }
    }
  }
}

Other MCP clients

Any MCP-compatible client that supports stdio transport can use this server. Use the generic configuration at the top of this section, adapting it to your client's config format. The command is always npx with args ["-y", "altmetric-mcp"] plus the environment variables for your API keys.

Troubleshooting

Problem	Solution
command not found: node	Node.js is not installed. Download it here (version 20.6.0 or later).
Claude Desktop won't start after editing config	The JSON file has a syntax error. Check for missing commas, unmatched brackets, or trailing commas. Paste it into jsonlint.com to validate.
"MCP server failed to start"	Run npx -y altmetric-mcp in Terminal to see the actual error. Usually a missing/invalid API key or Node.js version too old.
Tools appear but return 403 errors	You're using a free-tier key with a commercial-tier tool (get_citation_details). Use get_citation_counts or search_citations instead.
First query is slow	Normal. npx downloads the package on first run. Subsequent uses are faster.
Explorer tools fail	Explorer tools need both ALTMETRIC_EXPLORER_API_KEY and ALTMETRIC_EXPLORER_API_SECRET. Make sure both are set.

API Tiers

Details Page API

• Free Tier: Access to get_citation_counts and search_citations
• Commercial Tier: Access to all Details Page tools including get_citation_details

If you attempt to use get_citation_details with a free API key, you'll receive a 403 error.

Explorer API

• Institutional Access Only: All Explorer API tools require institutional credentials
• Provides access to research outputs and attention data across the entire Altmetric database
• Organizations with data integrations can also access their own institutional research outputs in isolation
• Includes advanced filtering by author, department, journal, and custom organizational metadata

Tools

This server provides nine tools across two APIs:

Tool	API	Tier	Description
get_citation_counts	Details Page	Free	Attention metrics by identifier (DOI, PubMed ID, etc.)
get_citation_details	Details Page	Commercial	Full mention text, author details, metadata
search_citations	Details Page	Free	Search attention data across all outputs by timeframe
explore_research_outputs	Explorer	Institutional	Search and filter research outputs
explore_attention_summary	Explorer	Institutional	Aggregated attention metrics by source and date
explore_mentions	Explorer	Institutional	Individual mention details with filtering
explore_demographics	Explorer	Institutional	Audience geographic and demographic data
explore_mention_sources	Explorer	Institutional	Source/outlet analysis for mentions
explore_journals	Explorer	Institutional	Journal metrics, rankings, and search

For detailed parameters and examples, see TOOLS.md.
