Local command
uvx fcvm-mcp==0.7.0Credentials from the publisher
- FCVM_MCP_NETWORK — Pin the network policy for every sandbox: none, or an allowlist such as @pypi,@github
- FCVM_MCP_TEMPLATE — Template used when the agent names neither an image nor a template, e.g. python-sandbox
- FCVM_MCP_TTL — Stop sandboxes this long after boot unless the agent sets a lifetime, e.g. 4h
- FCVM_MCP_IDLE_STOP — Stop sandboxes that saw no exec or file operation for this long, e.g. 30m
- FCVM_MCP_SECRETS — Names of environment variables passed into every sandbox as secrets, e.g. GITHUB_TOKEN
- FCVM_MCP_FORWARD — Host credentials relayed into every sandbox: ssh-agent, git
- FCVM_MCP_CACHE — 1: restricted sandboxes fetch pip and npm packages through the host's mirror
- FCVM_MCP_JAIL — 0: don't run sandboxes under the Firecracker jailer even when it is set up
- FCVM_BIN — Path of the fcvm command, when it isn't on PATH, in ~/.local/bin or in /usr/local/bin
