Comma plugin for Claude Code

Publish, search, and link to Comma reports without leaving your Claude Code session — plus an interactive review flow that feeds your anchored comments back to Claude as structured feedback.

This repository is an auto-published mirror. The source of truth lives in the main Comma repository (private) and a GitHub Action pushes changes here. Issues and pull requests opened here won't be seen — report problems via https://commareports.com/contact.

Install (one line)

curl -fsSL https://commareports.com/install.sh | bash

Windows (PowerShell):

iwr -useb https://commareports.com/install.ps1 | iex

Manual install

# 1. Add the marketplace (this repo)
claude plugin marketplace add doramirdor/comma-plugin

# 2. Install the plugin
claude plugin install comma@comma

# 3. Export your token (put this in your shell profile)
export COMMA_API_TOKEN=comma_sk_your_token_here

Mint a token at https://commareports.com/settings?section=tokens — it starts with comma_sk_. Restart Claude Code after installing so it picks up the plugin's MCP attachment.

Frequently asked questions

What is Comma?

Publish HTML reports to a share link, collect anchored comments, revise at the same URL.

How do I install Comma?

It runs as a remote server. In Claude Code: claude mcp add --transport http comma 'https://commareports.com/api/mcp' --header 'Authorization: <Bearer comma_sk_... token (free). Create one at commareports.com: Settings > API tokens > New token.>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Comma need an API key?

Yes. It expects Authorization, which you set in its configuration.

Is Comma open source?

Its code is public on GitHub, but the repository does not declare a standard license.

Who maintains Comma?

It is published by doramirdor. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
