Install langfuse for Codex and Claude Code

Installs for the current user

claude plugin marketplace add IchenDEV/agent-plugin-mkt
claude plugin marketplace update agent-plugin-marketplace
claude plugin install langfuse-4@agent-plugin-marketplace

Paste and run these commands in a terminal with Claude Code. They add and refresh the PluginsMP catalog, then install this plugin.

Compatibility: the page URL and API slug “langfuse-4” remain stable.

Codex: Legacy selector langfuse-4@agent-plugin-marketplace remains documented for migration; install from source for this runtime.

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Codex has another source with the same manifest name. This directory does not invent numbered install aliases; use the publisher's catalog or inspect the source manually for that runtime.

Get the source manually

$ git clone https://github.com/avivsinai/langfuse-mcp

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The repository root is the plugin root.
