Model Context Protocol (MCP) server
NAME func mcp - Model Context Protocol (MCP) server
SYNOPSIS func mcp [command] [flags] DESCRIPTION The Functions Model Context Protocol (MCP) server can be used to give agents the power of Functions.
Configure your agentic client to use the MCP server with command
"func mcp start". Then get the conversation started with
"Let's create a Function!".
By default the MCP server operates in read-only mode, allowing Function
creation, building, and inspection, but preventing deployment and deletion.
To enable full write access (deploy and delete operations), set the
environment variable FUNC_ENABLE_MCP_WRITE=true.
This is an experimental feature, and using an LLM to create and deploy
code running on your cluster requires careful supervision. Functions is
an inherently "mutative" tool, so enabling write mode for your LLM is
essentially giving (sometimes unpredictable) AI the ability to create,
modify, deploy, and delete Function instances on your currently connected
cluster.
The command "func mcp start" is meant to be invoked by your MCP
client (such as Claude Code, Cursor, VS Code, Windsurf, etc.); not run
directly. Configure your client of choice with a new MCP server which runs
this command. For example, in Claude Code this can be accomplished with:
claude mcp add func func mcp start

AVAILABLE COMMANDS start Start the MCP server (for use by your agent)
