Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
generate_kde_colorschemeGenerate a complete KDE Plasma color scheme from 3 base hex colors (background, foreground, accent) and auto-derive all 40+ color entries. Writes to ~/.local/share/color-schemes/ and applies it immediately.
set_kde_fontsChange KDE Plasma system fonts (general, fixed-width, and small fonts). Uses comma-separated KDE font descriptor format: 'Family,PointSize,Style,Weight,Width,Spacing,FixedPitch,Stretch'.
set_kde_cursorsChange the KDE Plasma mouse cursor theme and size.
get_kde_fonts_and_cursorsRead current KDE Plasma font and cursor configuration.
get_kde_nightlightRead the current KWin Night Light (blue light filter) configuration including enabled state, temperature, color temperature, mode, and schedule.
set_kde_nightlightConfigure KWin Night Light (blue light filter). Can enable/disable, adjust color temperature (3000-6500K), and set automatic scheduling.
kde_store_list_installedList installed KDE Store packages filtered by type (LookAndFeel, PlasmaTheme, etc.).
kde_store_installInstall a package from the KDE Store by name. Downloads and activates the package via kpackagetool6.
kde_store_removeRemove an installed KDE Store package by name.
kde_system_infoQuery detailed system information: KDE Plasma version, KDE Frameworks version, compositor status/backend, GPU details, and display configuration.
kde_power_profileGet or set the system power profile (power-saver, balanced, performance) using powerprofilesctl.
kde_screen_lockLock the screen, start a screensaver, or simulate user activity to prevent screen lock.
get_kde_settingsRead all current KDE Plasma settings: global theme, color scheme, cursors, fonts, icons, wallpaper per virtual desktop, compositor, night light, and window decoration.
set_kde_themeChange the global KDE Plasma look-and-feel theme (applies theme, colors, window decorations, and cursors from a single theme package).
set_kde_colorschemeChange the KDE Plasma color scheme independently of the global theme.
list_kde_themesList available look-and-feel themes, color schemes, cursor themes, and icon themes installed on the system.
set_kde_wallpaperSet the desktop wallpaper for all virtual desktops. Provide either a local image path or a solid color.
get_kde_wallpaperRead the current wallpaper configuration for all virtual desktops.
kde_window_managementList, manipulate, or query windows via KWin D-Bus. Supports listing all windows, closing, minimizing, maximizing, restoring, and activating specific windows by ID.
kde_virtual_desktopsManage KWin virtual desktops: list, add, remove, switch to, or rename desktops.

Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
20/20 tools missing one or more hints — generate_kde_colorscheme (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); set_kde_fonts (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); set_kde_cursors (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +17 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Descriptions match behaviour
3 tools describe read intent but their handlers mutate — kde_store_list_installed (line 27: KdeCli.exec("kpackagetool6", ["-t", type, "-l"], 10000)); kde_system_info (line 13: KdeCli.exec("plasmashell", ["--version"])); list_kde_themes (line 104: KdeCli.exec("plasma-apply-lookandfeel", ["--list-themes"]))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
15/20 tool handlers declare input schemas (75%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 3/20 tool handlers wrap calls in try/catch (15%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
28 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.0.0 (high), zod@3.22.0 (low)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Tool description accuracy
4 tools have description/behavior mismatches: kde_store_list_installed: description implies read-only but handler writes/deletes/executes; kde_system_info: description implies read-only but handler writes/deletes/executes; set_kde_theme: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
