What is the key difference between Appendix and Library?

Appendix belongs to the Biology & Bioinformatics category with cloud HTTP/SSE execution, while Library belongs to the Biology & Bioinformatics category with cloud HTTP/SSE execution.

How do I install Appendix or Library in Claude Desktop or Cursor?

Copy the mcpServers JSON configuration snippet provided on this page into your claude_desktop_config.json or ~/.cursor/mcp.json file and restart your AI client.

Are Appendix and Library free or paid?

Appendix operates under a Free / Open Source model (No auth required). Library operates under a Free / Open Source model (No auth required).

Which MCP server has more tools and community activity?

Appendix lists 3 tools with 0 views and 1 GitHub stars. Library lists 0 tools with 0 views and 0 GitHub stars.

Can I use both Appendix and Library together in the same MCP host?

Yes! MCP hosts like Claude Desktop, Cursor, Windsurf, Cline, and VS Code support configuring multiple servers under the mcpServers object simultaneously.

How do I install Appendix or Library in Claude Desktop, Cursor, or Windsurf?

Both servers follow the standard Model Context Protocol configuration format. Simply copy the JSON block from the configuration section above and paste it into your AI client's mcpServers configuration object (for instance in claude_desktop_config.json or ~/.cursor/mcp.json ), then completely restart or refresh the application.

Are Appendix and Library free to use, or do they require API keys?

Appendix is listed under a Free / Open Source model with No auth required . Library operates under a Free / Open Source model with No auth required . If environment variables are required (such as API keys), be sure to define them under the env key in your MCP client's configuration file.

Can I run both Appendix and Library at the same time in my AI client?

Yes! MCP clients support multi-server orchestration. You can include both appendix and library-6 as distinct keys inside the single mcpServers object in your configuration file. Your AI assistant will automatically select and call the appropriate tool from either server during chat sessions.

Which MCP server has higher directory engagement and quality ratings?

On AllMCPs, Appendix has a Quality Score of 48 /100 ( Fair ) with 0 views, 0 installs, and 1 GitHub stars. Library holds a Quality Score of 42 /100 ( Fair ) with 0 views, 0 installs, and 0 GitHub stars.
