imgcli-mcp
Convert, resize, crop, rotate, filter, and composite images from the command line — a lightweight, dependency-free, ffmpeg-style alternative to ImageMagick for still images. Wraps the imgcli CLI and exposes convert_image, probe_image, and list_filters tools.
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.
convert_imageprobe_imageReturn the width, height, and channel count of an image without converting it.
list_filtersList the full imgcli filter catalogue (geometry, colour, convolution, compositing).
IMGCLI_BINPORTTool 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
3/3 tools missing one or more hints — convert_image (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); probe_image (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_filters (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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
2 tools describe read intent but their handlers mutate — probe_image (line 32: execFile(BIN, args, { timeout: 60_000, maxBuffer: 8 * 1024 * 1024 }, (err, stdout, stderr) => {); list_filters (line 32: execFile(BIN, args, { timeout: 60_000, maxBuffer: 8 * 1024 * 1024 }, (err, stdout, stderr) => {)
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
2/3 tool handlers declare input schemas (67%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
2/3 tool handlers wrap calls in try/catch (67%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
Tool description accuracy
list_filters: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
