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.

cssgraph_explore

PRIMARY TOOL: Get the full style context for a className — properties, overrides, specificity, and callers in one call.

cssgraph_search

Search for className selectors by name.

cssgraph_callers

Find JSX components that reference a className.

cssgraph_impact

Analyze the impact radius of changing a className.

cssgraph_rule

Analyze the impact radius of a CSS selector (exact, related selectors, class usage, loose/strict impact).

cssgraph_details

Quick exact match: find files defining a specific CSS selector string.

cssgraph_impact_selector

Find code files (JS/TS/JSX/TSX/es6) affected by a CSS selector — strict (all classes) and loose (any class) impact.

cssgraph_files

List project style files from the index.

cssgraph_status

Show index statistics.

cssgraph_unused

Find CSS class selectors that have no incoming references.

cssgraph_cascade

Visualize the cascade path for a className, ordered by specificity.

cssgraph_diagnose

Static anchor diagnosis for scroll/height issues. Walks the DOM ancestor chain and classifies each level's height declaration as DEFINITE (absolute unit, usable as anchor), INDEFINITE (%), or UNVERIFIABLE (auto/none). Detects compensation red flags (overflow + large margin, fixed + %, max-height onl

cssgraph_property

Search selectors by CSS property value (e.g. property="display", value="flex").

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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

13/13 tools missing one or more hints — cssgraph_explore (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cssgraph_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cssgraph_callers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +10 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 test coverage

Only 1/13 tools referenced in tests (8%)

Write tests that reference each tool by name so every tool has at least one test.

No eval / new Function

1 eval() or new Function() call — dynamic code execution

Replace eval / Function with explicit parsing or safer alternatives.

Shell command execution

1 call in production code run through a shell (src/installer/index.ts:98)

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 — postcss@8.5.16 (high), postcss@8.5.16 (medium)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dependency freshness

3/11 production deps abandoned (no release in 2+ years): postcss-less@2022-06-24 (4.2y), postcss-scss@2023-09-28 (3y), source-map-js@2024-09-08 (2y)

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
