AI agents (MCP)

The Model Context Protocol (MCP) lets the AI agents of VS Code, for example the agent mode of Copilot, call tools. mise and pitchfork both ship an MCP server, and the extension can provide them to VS Code, started in the current workspace folder, so there is no mcp.json to write:

• mise mcp: the project’s tools, tasks, environment variables and config files, and tools to run its tasks and install tools.
• pitchfork mcp: the status of the daemons, and tools to start, stop and restart them and read their logs. With pitchfork 2.32.0 or later, it is kept to the daemons of the project (--local); before, it reaches the daemons of every project of the machine.

They are off by default. Turn them on in your user settings:

{
  "mise.mcpServers": ["mise", "pitchfork"]
}

They then appear in the MCP servers of VS Code (MCP: List Servers), where they can be started, stopped or turned off like any other server. Switching to another workspace folder, or to another mise.miseEnv, updates them.

Caution

The environment resource of mise mcp holds the real values of the project’s environment variables, secrets included, and its tools can run tasks and install tools. Turn it on for projects and agents you trust; VS Code asks before an agent runs a tool, depending on your settings. See the security notes of mise, such as MISE_SAFE=1.

This requires mise 2026.6.6 or later for mise mcp, and pitchfork 2.25.0 or later for pitchfork mcp. Only the user settings can set mise.mcpServers, not a project’s.
