Common questions

Is Lycatra 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 (0.2.4) reached the registry yesterday.

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?

Lycatra plugin

Lycatra for Claude, ChatGPT, Codex, Cursor, VS Code, and any other app that speaks MCP: your agents, wiki, memory, teams, schedules, notifications, Matrix chat, and vault, in one sign-in.

Install

Every app below connects to https://lycatra.com/api/mcp and asks you to sign in to Lycatra once. One-click buttons for every app are on lycatra.com/connect.

Claude

Claude on the web, desktop, and mobile, and Cowork.

Recommended: the plugin, with skills:

In Claude, open Customize, then Plugins, then Add marketplace.
Enter Lycatra/lycatra-plugin and turn on Sync automatically.
Install Lycatra, then connect it when Claude asks you to sign in.

Add as a connector only

Add for your organization

A plugin added here also appears in Claude Code when you sign in with the same account.

Team and Enterprise plans: an organization owner adds Lycatra, then members connect it.

ChatGPT

ChatGPT on the web and desktop.

Developer mode:

In ChatGPT, open Settings, then Security and login, and turn on Developer mode.
Open chatgpt.com/plugins, choose the plus button, and enter https://lycatra.com/api/mcp.
Sign in to Lycatra when ChatGPT asks.

Open ChatGPT plugins

Until Lycatra is in the ChatGPT directory, adding it needs developer mode, which depends on your plan.

Claude Code

Lycatra tools, plus the Lycatra CLI for work that needs your computer.

claude plugin marketplace add Lycatra/lycatra-plugin

claude plugin install lycatra@lycatra

Turn on updates in /plugin, Marketplaces, then Enable auto-update. lycatra setup does this for you.

Codex

The Codex CLI, the Codex app, and ChatGPT desktop.

codex plugin marketplace add Lycatra/lycatra-plugin

codex plugin add lycatra@lycatra

Codex IDE extension (tools only):

codex mcp add lycatra --url https://lycatra.com/api/mcp

Cursor

Lycatra tools in Cursor's agent.

Add to Cursor

VS Code

GitHub Copilot in VS Code.

Any other MCP client

Add the MCP server URL. It signs in with OAuth.

Set up every agent add-mcp finds:

npx add-mcp https://lycatra.com/api/mcp

The Lycatra CLI

Agents that can run shell commands install it themselves the first time they need your computer, for example to run a command inside one of your agents. To install it yourself:

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

irm https://lycatra.com/install.ps1 | iex

How it works

Every app talks to Lycatra's hosted MCP server for anything stored in your account: agents, wiki, memory, schedules, notifications, teams, Matrix, vault metadata, and a browser that runs inside your agents. You sign in once with Lycatra's OAuth prompt, and the app only sees what your account can access.

Hosted MCP and the Lycatra CLI are both supported interfaces. An authorized local or cloud shell can use the checksum-verified CLI for the same account operations. Local ports and child processes additionally need suitable runtime capabilities. Ordinary hosted tools do not require a personal computer.

Cloud event delivery is negotiated with the receiving host when supported by the server. It continues independently of a CLI shell. The CLI can inspect and manage owner-authorized subscriptions, but cannot manufacture a host callback or wake a chat by name. Start with lycatra notify targets doctor --json for read-only diagnosis. Local notify wake adapters remain separate.

For explicit cloud-agent enrollment, use the selected environment's /api/mcp/cloud resource returned by notify targets connect. Compatible hosts discover its starter scopes and follow OAuth enrollment and consent. The normal /api/mcp resource retains human-account behavior. Cloud event support still requires qualification in the receiving host.

Explicitly approved notify events subscriptions resync --yes skips one parked or cancelled head event and reports the skipped sequence and new cursor. It does not retry that event or change subscription pause or lease expiry.

Beta uses dev and stable uses production throughout installation, login and updates. Each CLI profile has separate credentials and update state. Provider credential setup for local coding harnesses is optional, separate from login.

Your app's normal permission prompts still apply to writes, deletions, and anything visible to other people.
