Claude Code and Codex

Install the BioLib plugin (recommended)

The recommended way to use BioLib from Claude Code or Codex is to install the BioLib plugin. The plugin adds the BioLib MCP server, and a skill that teaches the agent how to run applications with pybiolib. The plugin is installed from this BioLib instance, and is already set up to connect to it.

In Claude Code:

/plugin marketplace add https://biolib.com/api/plugins.git
/plugin install biolib@biolib

In Codex:

codex plugin marketplace add https://biolib.com/api/plugins.git
codex plugin add biolib@biolib

To add the MCP server without the plugin, see MCP.

Sign in

In Claude Code, run /mcp and select the biolib server to sign in. In Codex, run:

codex mcp login biolib

Both open a BioLib page in your browser where you click Authorize. Read more about signing in here.
