Introduction

AgentSeal is an FSL-1.1 (future Apache-2.0) toolkit that scans skills and MCP configs, monitors supply-chain risks, and tests prompt-injection resistance.

Best for: teams hardening agent configs before production and continuously monitoring prompt/MCP attack surfaces

Works with: Python or Node installs, Ollama for local inference, MCP servers (stdio/SSE) for audits

Setup time: 5-10 minutes

Key facts (verified)

  • GitHub: 254 stars · 38 forks · pushed 2026-04-29.
  • License: FSL-1.1-Apache-2.0 · owner avatar + repo URL verified via GitHub API.
  • README-verified entrypoint: pip install agentseal # or: npm install agentseal.

Main

  • Use guard as a preflight: scan skills and MCP configs for risky patterns before you ship a new agent build.

  • Use scan to measure prompt robustness over time—treat it as a regression test suite for system prompts.

  • Audit MCP servers you rely on: tool descriptions are part of your trust boundary, so poisoning detection matters.

Source-backed notes

  • README Quick Start includes agentseal guard for offline scanning with no API key.
  • README lists commands like scan (prompt probes) and scan-mcp (audit live MCP tool descriptions).
  • README mentions baseline tracking with SHA-256 hashes to detect changes since last scan.

FAQ

  • Does it work offline?: Yes—README says guard, shield, and scan-mcp can work offline.
  • Do I need a model for scanning prompts?: For scan, yes; use Ollama locally or a cloud model.
  • Is it open source?: License is FSL-1.1 (future Apache-2.0); review LICENSE for usage terms.
