Credentials from the publisher

MCP_EXEC_TRANSPORT — MCP transport. Must be 'stdio' for direct docker/stdio use.
MCP_EXEC_DEFAULT_TIMEOUT_S — Default wall-clock timeout per exec, seconds.
MCP_EXEC_MAX_TIMEOUT_S — Maximum wall-clock timeout a caller may request, seconds.
MCP_EXEC_MAX_OUTPUT_BYTES — Cap on combined stdout/stderr before truncation.
MCP_EXEC_MAX_STDIN_BYTES — Cap on stdin passed to the sandboxed code.
MCP_EXEC_AUTH_TOKEN — Optional X-MCP-AUTH token (http/sse transports only).

Claude Code has no install link for a local command. Copy the command below and run it in a terminal.
