Findings

informational permission_audit methodology

__tests__/directory-tree.test.ts:64

Matched fs.writeFile

Suggested action The server writes to the filesystem. Verify the server documents which paths it touches.

Patterns fs-write

Matched fs.readdir

Suggested action The server reads from the filesystem. Verify the server documents which paths it accesses.

What we couldn't check

dynamic_tool_descriptions
Static analysis only sees descriptions hardcoded in source. Servers that compute descriptions at runtime (server-generated tools/list responses) are not covered by Check 1 at v0.
ast_indirection
v0 regex sees only literal description strings. Descriptions assembled by concatenation or pulled through variable indirection evade detection until AST-level extraction lands in v1.

Install configuration

Universal install-config generation across agent clients (Claude Code, Cursor, Windsurf, ChatGPT Apps, Continue, Cline, Zed) is a v0 deliverable. For now, install per the publisher's repository instructions linked above. The auto-generated client-specific configuration block lands here when the install-config generator ships.

Disclaimer

Scan results describe what our static checks found and didn't find at the time of scan. They are not a recommendation, certification, or guarantee. A scanned-clean result is the absence of evidence of malice, not the presence of evidence of integrity. Servers can be compromised after scan. You are responsible for evaluating whether to install any MCP server. See our methodology for what we check, what we can't check, and the limits of static analysis.
