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.
analyze_fileAnalyze a file and return its metadata. For images: dimensions, color space, DPI, EXIF data. For audio/video: duration, codec, bitrate, sample rate. For all files: size, format detection, entropy.
convert_fileConvert a file from one format to another. Supports images, audio, video, documents, and structured data. All processing happens locally.
generate_fileGenerate placeholder and test files from scratch -- no input file needed. All processing is local. SET 'type' TO ONE OF THESE, then use the parameters listed for that type: ## type: "text" Generates lorem ipsum placeholder text. Output: .txt file. Params: text_mode (paragraphs|sentences|words), te…
get_conversion_optionsGet available options and their defaults for a specific output format.
list_formatsList all supported file formats, optionally filtered by category or by what a given input format can convert to.
merge_filesMerge multiple files into one. Supports: combining PDFs, images into a PDF, text/data file concatenation, and CSV merging.
process_imageProcess an image: resize, compress, rotate, flip, blur, sharpen, grayscale, strip EXIF metadata, or change format. Outputs to a new file.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
fast-xml-parser has an entity encoding bypass via regex injection in DOCTYPE entity names
When Vitest UI server is listening, arbitrary file can be read and executed
Vitest allows Remote Code Execution when accessing a malicious website while Vitest API server is listening
fast-xml-parser affected by numeric entity expansion bypassing all entity expansion limits (incomplete fix for CVE-2026-26278)
fast-xml-parser affected by DoS through entity expansion in DOCTYPE (no expansion limit)
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
7/7 tools missing one or more hints — analyze_file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); convert_file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); generate_file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 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.
Tool handlers catch errors
5/7 tool handlers wrap calls in try/catch (71%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 1/7 tools referenced in tests (14%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
1 critical, 5 high severity in production deps — fast-xml-parser@4.5.0 (critical), fast-xml-parser@4.5.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
1/11 production deps stale: ffprobe-static@2022-06-18 (4y)
