Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit d03f3e21eec1, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    packages/openapi-mcp-generator/src/index.ts, line 290 await fs.rm(outputDir, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    packages/openapi-mcp-generator/src/generator/streamable-http.ts, line 470 const response = await fetch('/mcp', {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    packages/openapi-mcp-generator/src/index.ts, line 117 const envExamplePath = path.join(outputDir, '.env.example');

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    packages/mcp-api/src/index.ts, line 1 #!/usr/bin/env node

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
