Generate production-ready MCP (Model Context Protocol) servers from natural language descriptions, OpenAPI specs, database schemas, GraphQL schemas, or ontologies.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

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

Rescanned at commit 7aa12b186f71, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/graphql/generator.ts, line 264 ' const response = await fetch(GRAPHQL_ENDPOINT, {',

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    src/graphql/generator.ts, line 264 ' const response = await fetch(GRAPHQL_ENDPOINT, {',

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/config/config.ts, line 18 // Load .env file on module import

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    src/security/index.ts, line 145 message: 'child_process.exec() is vulnerable to command injection',

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    src/graphql/generator.ts, line 247 "const GRAPHQL_AUTH_TOKEN = process.env.GRAPHQL_AUTH_TOKEN ?? '';",

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    package-lock.json, line 1 {

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach api.weather.com. The description does not name that host. can reach api.example.com. The description does not name that host.
