Slack Lists MCP Server — Full Read/Write Slack Lists for AI

Q: What is the Slack Lists MCP server?

It is an open-source Model Context Protocol (MCP) server that connects AI assistants like Claude to Slack Lists, giving them full read and write access so they can manage tasks directly inside your Slack workspace.

Q: What can AI do with Slack Lists through this MCP?

Eight tools: create one or many items, fetch and filter them, export to JSON or CSV, and — uniquely — update any cell (check off, reassign, reschedule, edit), delete rows, and auto-discover column IDs and select options.

Q: How do I install the Slack Lists MCP with Claude Code?

It is published on PyPI as ars-slack-lists-mcp, so one command installs and registers it: claude mcp add slack-lists -s user -e SLACK_BOT_TOKEN=xoxb-... -- uvx ars-slack-lists-mcp. The token needs lists:read and lists:write scopes. You can also clone the repo and run it from a .env file if you prefer to keep the token out of your config.

Q: Is the Slack Lists MCP server free and open source?

Yes. It is MIT-licensed and free to use, derived from maplehilllabs/mcp-slack-lists and extended with the write tools.

Q: What Slack permissions does it need?

A Slack app with the lists:read and lists:write bot scopes. The bot must also be given access to each List it should manage. Slack Lists is available on paid Slack plans.

Why this fork exists

Slack Lists are great. Read-only AI isn't.

The original community server could create and read items — so an AI could file a task but never actually finish it. This fork adds the write side, so Claude can run real task management in Slack.

Upstream — read only

Files tasks. Then stops.

AI could open items and list them, but the moment a task needed updating it had to hand control back to you.

No check-off, no reassign, no reschedule
No delete
Column IDs hunted by hand in dev tools

This fork — full lifecycle

Runs tasks end to end.

Three new write tools plus full field-type support turn Claude into an actual project manager for your Slack Lists.

Update any cell — check off, reassign, reschedule, edit
Permanently delete rows
Auto-discover column & option IDs

Up in one command

Point Claude at your workspace.

It's on PyPI — install and register in a single line. Just bring a Slack bot token with lists:read + lists:write.

bash — setup

# fastest · straight from PyPI, no clone
$ claude mcp add slack-lists -s user \
-e SLACK_BOT_TOKEN=xoxb-… -- uvx ars-slack-lists-mcp

# prefer your token out of the config? run from source with a .env
$ git clone https://github.com/justadityaraj/slack-lists-mcp.git
$ cd slack-lists-mcp && python3 -m venv .venv
$ .venv/bin/pip install -r requirements.txt

$ claude mcp add slack-lists -s user -- .venv/bin/python src/slack_lists_server.py

# ✓ Status: Connected — 8 tools ready

Create a Slack app with lists read + write scopes.

Share the List with your bot so it can reach the rows.

What is the Slack Lists MCP server?

It's an open-source Model Context Protocol (MCP) server that connects AI assistants like Claude to Slack Lists, giving them full read and write access — so they can manage tasks directly inside your Slack workspace instead of just reading them.

What can AI do with Slack Lists through this MCP?

Eight tools in total: create one or many items, fetch and filter them, export to JSON or CSV, and — uniquely — update any cell (check off, reassign, reschedule, edit), delete rows, and auto-discover column IDs and select options.

How is this different from the original maplehilllabs Slack Lists MCP?

The upstream server was read and create only. This fork adds the write side — update_list_item, delete_list_item and discover_list_columns — plus full Slack field-type support for text, date, user, select, checkbox, number, email and phone.

How do I install the Slack Lists MCP with Claude Code?

It's published on PyPI, so one line does it: claude mcp add slack-lists -s user -e SLACK_BOT_TOKEN=xoxb-… -- uvx ars-slack-lists-mcp (the token needs lists:read and lists:write scopes). Prefer keeping the token out of your config? Clone the repo and run it from a .env instead — both paths are in the install section above.
