MCP, MCP server

Synaptic Code Intelligence

Synaptic Code Intelligence, an MCP server listed in the PlugVet directory.

Compatibility: Not stated.

Grade B

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

Graded by PlugVetRubric v2

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

Rescanned at commit c852b255f252, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    install.sh, line 19 if command -v curl >/dev/null 2>&1; then

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    install.sh, line 19 if command -v curl >/dev/null 2>&1; then

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    bin/synaptic-ui/src/main.rs, line 3467 .env("SYNAPTIC_UPDATE_CHECK", "0")

  • PERMISSION_SHELL_DECLARED Note

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

    bin/synaptic/src/commands/extract.rs, line 332 // node (e.g. Python subprocess.run("tool") -> the Rust binary src/bin/tool.rs).

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 31 curl --proto '=https' --tlsv1.2 -LsSf https://raw.githubusercontent.com/ColinVaughn/Synaptic/main/install.sh | sh

  • SECRETS_ENV_READ Note

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

    automation/api-maintenance/network-guard.mjs, line 42 process.env.SYNAPTIC_TEST_TOKEN = "

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    crates/synaptic-extract/src/crosslang.rs, line 1 //! Cross-language linkage post-passes (gated on the `cross-language` feature).

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

    crates/synaptic-extract/src/crosslang.rs, line 1 //! Cross-language linkage post-passes (gated on the `cross-language` feature).

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

    Note

    requests shell access. The manifest names this permission.
