MCP, MCP server
GaugeMesh
One endpoint for MCP capabilities and model routes, without losing identity, authority, budgets, deadlines, side-effect semantics, or causal evidence between protocols.
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.
NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB OBFUSCATION_MINIFIED_PAYLOAD PERMISSION_SHELL_DECLARED SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
scripts/readme_smoke.py, line 81
with urllib.request.urlopen( - SECRETS_PATH_DOTENV Low
Mentions a .env file.
crates/gaugemesh/src/outbound.rs, line 2115
.env(NEUTRAL_WORKER_ENV, "1") - OBFUSCATION_ENCODED_BLOB Low
Contains a long base64 shaped string in a file that should be readable.

Runs shell commands, and the manifest or description says so.
examples/concrete_review/beam_worker.py, line 140
proc = subprocess.Popen([sys.executable, __file__, "--root", str(root), "--child", task_id], stdin=subprocess.PIPE, stdout=subprocess.DEVNULL, stderr=errors, text=True) - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
scripts/verify_repository_rules.py, line 60
token = os.environ.get("GITHUB_TOKEN")
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.
