Grades are a hygiene check, not a security guarantee.

MCP, MCP server

Mcp Gateway

A production-ready API gateway for Model Context Protocol (MCP) servers, providing enterprise-grade infrastructure with authentication, logging, rate limiting, server discovery, and multi-protocol transport support.

Compatibility: Not stated.

Grade D

Two or more Medium findings, or a High. Only try it in a sandbox.

Graded by PlugVetRubric v2

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

PERMISSION_SHELL_UNDECLARED INSTALL_REMOTE_SCRIPT OBFUSCATION_ENCODED_BLOB

Why this grade

  • PERMISSION_SHELL_UNDECLARED Medium

    Runs shell commands that the manifest or description does not mention.

    apps/backend/internal/mcp/stdio.go, line 29 cmd := exec.CommandContext(ctx, config.Command, config.Args...)

  • INSTALL_REMOTE_SCRIPT Medium

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    apps/backend/Dockerfile, line 9 curl -LsSf https://astral.sh/uv/install.sh | sh && \

  • OBFUSCATION_ENCODED_BLOB Medium

    Contains a long base64 shaped string in a file that should be readable.

    apps/frontend/bun.lock, 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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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

    Concern

    requests shell access. No manifest field names shell or command execution.

    PERMISSION_SHELL_UNDECLARED

    apps/backend/internal/mcp/stdio.go, line 29

    cmd := exec.CommandContext(ctx, config.Command, config.Args...)

    apps/backend/internal/server/handlers/transport_stdio.go, line 157

    cmd := exec.CommandContext(cmdCtx, stdioCmd.Command, stdioCmd.Args...)

    apps/backend/internal/transport/stdio.go, line 86

    s.cmd = exec.CommandContext(ctx, s.command, s.args...)

  • Install and update

    Serious

    install fetches a script from the network.

    INSTALL_REMOTE_SCRIPT

    apps/backend/Dockerfile, line 9

    curl -LsSf https://astral.sh/uv/install.sh | sh && \

    apps/backend/Dockerfile, line 62

    curl -LsSf https://astral.sh/uv/install.sh | sh && \

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

    apps/frontend/src/lib/auth-api.ts, line 41

    const response = await fetch(url, {

    docs/examples/transport_apis_example.md, line 181

    ### Connect to WebSocket (using websocat or similar tool)

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_ENV_READ SECRETS_PATH_DOTENV

    apps/backend/cmd/migrate/main.go, line 49

    dbPassword := os.Getenv("DB_PASSWORD")

    2. **Environment Setup**: Create `.env` file with database credentials

  • Agent instructions

    Pass

    No instruction to ignore earlier instructions or to hide a step.

  • Obfuscation

    Concern

    contains an encoded blob in a file that should be readable.
