Grades are a hygiene check, not a security guarantee.

MCP, MCP server

Grade C

One Medium finding. Read the report before installing.

Graded by PlugVetRubric v2

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

AGENT_IGNORE_INSTRUCTIONS

Why this grade

  • AGENT_IGNORE_INSTRUCTIONS Medium

    Text tells the agent to ignore earlier instructions.

    CHANGELOG.md, line 4764 - **Prompt-injection scanner** - detects adversarial patterns in file content (`ignore previous instructions`, `new system prompt`, etc.). Wraps content in explicit `[BEGIN/END FIL

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.
