Overview

Description from the maker (original English)

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Games, sports, food & learning

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)

Common questions

Is Lichess by Cotlet safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

How to connect Lichess to Claude Code, ChatGPT and any AI agent

Yes, Claude, ChatGPT and other AI agents can work in your Lichess account. Cotlet.dev connects your own signed-in Lichess account to any AI agent, so you can ask in plain words and the AI accepts team join requests and sends updates to your team for you.

What you can ask

Accept the join requests from tom_k and anna_plays to my "Riverside Chess Club" team.

Show me all pending join requests for my team and who sent them this week.

Send a message to all members of "Riverside Chess Club": our blitz arena starts Thursday at 7 pm.

Accept every join request from today, then tell the team that 4 new players joined.

Message my team that Saturday's lesson with coach Maria moves to 10 am.

Connect in 2 minutes

Get your API key at https://cotlet.dev/app and export it as COTLET_API_KEY.

Claude Code
claude mcp add --transport http cotlet https://cotlet.dev/mcp/v1 --header "Authorization: Bearer $COTLET_API_KEY"
ChatGPT

Settings → Apps → add connector URL https://cotlet.dev/mcp/v1, then sign in with Cotlet.dev. No API key needed.

Cursor

Copy .cursor/mcp.json from this repo into your project:

{

"mcpServers": { "cotlet": { "url": "https://cotlet.dev/mcp/v1", "headers": { "Authorization": "Bearer ${COTLET_API_KEY}" } } } }

Run it locally (stdio)

This repo is a real MCP server. It speaks MCP over stdio, lists its Lichess tools without any key, and forwards every tool call to the hosted Cotlet.dev server. The hosted URL above stays the recommended way. Use this when your client only starts local servers.

{"mcpServers":{"lichess":{"command":"uvx","args":["lichess-mcp"],"env":{"COTLET_API_KEY":"your-key"}}}}

Or with Docker:

docker build -t lichess-mcp .

docker run -i --rm -e COTLET_API_KEY lichess-mcp

Tools: lichess_guide, lichess_status, lichess_open, lichess_read, lichess_click, lichess_type, lichess_close. Without COTLET_API_KEY a tool call answers: "Set COTLET_API_KEY. Get a key at https://cotlet.dev/app".

Command line

Python 3.10+, nothing else to install. From PyPI:

pip install lichess-mcp        # or run it once: uvx lichess-mcp connect

lichess-mcp connect

Or straight from this repo:

export COTLET_API_KEY="your-key"

python3 lichess_agent.py connect # ready config for Claude Code, Cursor, ChatGPT python3 lichess_agent.py status # is Lichess ready in your Cotlet.dev account python3 lichess_agent.py guide # Lichess screens and sign-in link python3 lichess_agent.py read # open Lichess, read the page, close the browser python3 lichess_agent.py tools # list Cotlet.dev tools python3 lichess_agent.py serve # start the stdio MCP server (same as no argument)

Questions from Lichess users

Does Lichess have an API?

Lichess has a full, free REST API with personal and OAuth tokens, but no official MCP server (checked 17 Oct 2026). The API covers teams, Arena and Swiss tournaments, studies, broadcasts, challenges and game export, so the gap is a hosted, maintained MCP with no token to create, scope or revoke. Cotlet.dev works in your own signed-in Lichess account, so your AI agent can accept team join requests and message your team with no API key and no code.

How do I connect Lichess to ChatGPT?

Add Cotlet.dev as an app in ChatGPT (Settings → Apps, connector URL https://cotlet.dev/mcp/v1), sign in to Lichess once in your Cotlet.dev Cloud Browser, and ask ChatGPT in plain words. No code and no Lichess API key.

Is there a way to use Claude with Lichess?

Yes. In Claude Code run the one-line claude mcp add command above; in the Claude app add https://cotlet.dev/mcp/v1 as a custom connector. Claude then works in your own Lichess account.

Is there a Lichess MCP server?

We found no official Lichess app in the ChatGPT or Claude directories. Cotlet.dev is a hosted MCP server that works in Lichess for you, 24/7, with Claude, ChatGPT, Cursor, Codex, n8n, Make and Zapier.
