Unleash

Q: Does Unleash need an API key?

Yes. It reads UNLEASH_BASE_URL y UNLEASH_PAT from its environment, and UNLEASH_PAT is a secret. Put the value in your client’s config on your own machine, never in a shared file.

Descripción

Connects an AI coding assistant to the Unleash Admin API. It can decide whether a code change needs a feature flag, check for existing flags, create flags, configure rollout strategies, toggle flags per environment and produce instructions for removing flagged code.

Runs locally over stdio with npx (@unleash/mcp). It needs Node.js 22 or higher, the URL of your Unleash instance and a personal access token. A default project ID can be set optionally. Unleash instances can also expose an experimental built-in remote MCP endpoint, which is separate from this package.

Qué puedes hacer

Create feature flags with validation and typing
Detect existing flags to avoid duplicates
Evaluate whether a code change needs a flag
Configure rollout strategies for a flag
Enable or disable a flag in an environment
List projects and flags, and read flag state
Generate cleanup instructions for removing flagged code

Herramientas

Unleash solo muestra sus herramientas a clientes con clave, así que no podemos listarlas aquí.

Prompts de ejemplo

Check if this change needs a feature flag and create one if so
List all feature flags in the checkout project
Set a 25% gradual rollout for the new-search flag
Show me the cleanup steps for the old-banner flag

Configuración

Todos los clientes inician Unleash en tu equipo con el mismo comando. Elige el tuyo; la página recuerda tu elección.

Claude Code

Run this in a terminal, in your project folder:

claude mcp add --transport stdio unleash --env "UNLEASH_BASE_URL=<YOUR_UNLEASH_BASE_URL>" --env "UNLEASH_PAT=<YOUR_UNLEASH_PAT>" -- npx -y @unleash/mcp@latest

Start Claude Code and type /mcp. unleash should show as connected.

Add --scope user to make it available in every project. Replace the placeholders with your own values.

Claude Desktop

Open Settings → Developer → Edit Config. It opens claude_desktop_config.json. Add:

claude_desktop_config.json

{
  "mcpServers": {
    "unleash": {
      "command": "npx",
      "args": [
        "-y",
        "@unleash/mcp@latest"
      ],
      "env": {
        "UNLEASH_BASE_URL": "<YOUR_UNLEASH_BASE_URL>",
        "UNLEASH_PAT": "<YOUR_UNLEASH_PAT>"
      }
    }
  }
}

Save the file and restart Claude Desktop. Replace the placeholders with your own values.

Needs Node.js on your computer. The file lives in ~/Library/Application Support/Claude/ on macOS and %APPDATA%\Claude\ on Windows.

Cursor

Añadir a Cursor (se abre en una pestaña nueva)

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json

{
  "mcpServers": {
    "unleash": {
      "command": "npx",
      "args": [
        "-y",
        "@unleash/mcp@latest"
      ],
      "env": {
        "UNLEASH_BASE_URL": "<YOUR_UNLEASH_BASE_URL>",
        "UNLEASH_PAT": "<YOUR_UNLEASH_PAT>"
      }
    }
  }
}

Needs Node.js on your computer. Replace the placeholders with your own values.

VS Code

Add it to .vscode/mcp.json. VS Code asks for the secret the first time and stores it securely:

.vscode/mcp.json

{
  "servers": {
    "unleash": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@unleash/mcp@latest"
      ],
      "env": {
        "UNLEASH_BASE_URL": "<YOUR_UNLEASH_BASE_URL>",
        "UNLEASH_PAT": "${input:unleash-pat}"
      }
    }
  },
  "inputs": [
    {
      "type": "promptString",
      "id": "unleash-pat",
      "description": "UNLEASH_PAT",
      "password": true
    }
  ]
}

Needs Node.js on your computer.

Devin Desktop

Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):

mcp_config.json

{
  "mcpServers": {
    "unleash": {
      "command": "npx",
      "args": [
        "-y",
        "@unleash/mcp@latest"
      ],
      "env": {
        "UNLEASH_BASE_URL": "<YOUR_UNLEASH_BASE_URL>",
        "UNLEASH_PAT": "<YOUR_UNLEASH_PAT>"
      }
    }
  }
}

Refresh the MCP server list in Cascade. Replace the placeholders with your own values.

Devin Desktop is the new name for Windsurf.

Codex

codex mcp add unleash --env "UNLEASH_BASE_URL=<YOUR_UNLEASH_BASE_URL>" --env "UNLEASH_PAT=<YOUR_UNLEASH_PAT>" -- npx -y @unleash/mcp@latest

Or edit ~/.codex/config.toml directly:

config.toml

[mcp_servers.unleash]
command = "npx"
args = ["-y", "@unleash/mcp@latest"]
env = { UNLEASH_BASE_URL = "<YOUR_UNLEASH_BASE_URL>", UNLEASH_PAT = "<YOUR_UNLEASH_PAT>" }

Needs Node.js on your computer. Replace the placeholders with your own values.

Gemini CLI

gemini mcp add -e "UNLEASH_BASE_URL=<YOUR_UNLEASH_BASE_URL>" -e "UNLEASH_PAT=<YOUR_UNLEASH_PAT>" unleash npx -- -y @unleash/mcp@latest

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients that start local servers accept this shape:

{
  "mcpServers": {
    "unleash": {
      "command": "npx",
      "args": [
        "-y",
        "@unleash/mcp@latest"
      ],
      "env": {
        "UNLEASH_BASE_URL": "<YOUR_UNLEASH_BASE_URL>",
        "UNLEASH_PAT": "<YOUR_UNLEASH_PAT>"
      }
    }
  }
}

Zed puts servers under context_servers in its settings, with the same command, args and env fields.

Needs Node.js on your computer. Replace the placeholders with your own values.

Preguntas frecuentes

Can I paste mcp.tc/i/unleash into my MCP client?

No. Unleash runs on your own computer, started by your client, so it has no web address to connect to. The quick link is the page to share; the install command is npx -y @unleash/mcp@latest.

Does Unleash need an API key?

Yes. It reads UNLEASH_BASE_URL y UNLEASH_PAT from its environment, and UNLEASH_PAT is a secret. Put the value in your client’s config on your own machine, never in a shared file.

Is Unleash a remote or a local server?

Local. Your client starts it as a process on your computer with npx -y @unleash/mcp@latest, which needs Node.js.

What can Unleash do?

You can create feature flags with validation and typing, detect existing flags to avoid duplicates y evaluate whether a code change needs a flag.

Which clients can use it?

Any client that starts local servers: Claude Code, Claude Desktop, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. claude.ai and ChatGPT only connect to remote servers.

Who wrote this page?

mcp.tc’s robot read Unleash’s public metadata (its package and repository pages), and an AI model drafted the text from it. A person reviews anything the checks can’t confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.
