Side-by-Side Model Context Protocol Comparison
Shield vs Agentscore MCP Server
In-depth architectural comparison of the Shield and Agentscore MCP Server MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Shield
Security · Local stdio
Quality: 63/100 (Good) | Auth: No auth required
Agentscore MCP Server
Security · Local stdio
Quality: 55/100 (Good) | Auth: No auth required
Verdict Summary: Choose Shield if you need specialized Security tools running via a local process. Choose Agentscore MCP Server if your workspace requires Security integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Shield when:
You need dedicated capabilities in the Security domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Primary tools included: Pre-execution MCP call guardrails, TOFU tool-catalog pinning, Tool description and result scanning.
Local guardrail proxy for AI coding agents. Wraps any MCP server (stdio or Streamable HTTP) and blocks destructive tool calls — DROP TABLE, rm -rf, force-push — before they execute. MCP supply-chain protection: TOFU tool-catalog pinning against rug pulls, plus tool-description and tool-result scanning for tool poisoning and prompt injection. 51 starter rules, approval gates, audit logging. Single binary, Apache-2.0.
MCP security trust layer. Continuously monitors 800+ MCP packages on npm for install scripts, command injection, hardcoded secrets, capability drift, and publisher posture. Ships a GitHub Action policy gate for PR-level allow/warn/block decisions with OIDC auto-provisioning. 5 MCP tools, no API key required.

Agentscore MCP Server Tools (8)
scan_package
Scan an npm package for MCP security issues. Checks install scripts, prompt injection patterns, suspicious URLs, source code patterns, dependency count, metadata completeness, and publisher provenance. Returns score (0-100), risk level, and detailed findings.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Shield is categorized under Security and uses a local stdio subprocess. In contrast, Agentscore MCP Server belongs to Security using local stdio subprocess. Select Shield when you need capabilities focused on security and Agentscore MCP Server when you require tools for security.
Get a trust verdict for an MCP package: allow, warn, or block. Based on scan findings (score and severity). Also reports monitoring status and publisher posture. Use this before installing or connecting to an MCP server.
check_exposure
Check which monitored MCP servers depend on a given package. Use this during incident response to find blast radius. Example: 'which MCP servers use axios?'
check_abuse
Check if a package or agent has been reported to the KYA abuse database. Returns whether abuse has been reported and any details.
monitor_status
Check if an MCP package is under continuous monitoring and get its scan history. Shows current score, risk level, and recent changes.
check_my_repo
Inspect the current repo for MCP dependencies, look up AgentScore verdicts for each package, and summarise what should be gated in CI. Use this when a developer wants to understand all MCP packages in a repo instead of scanning one package at a time.
generate_policy_gate_setup
Generate the exact GitHub Actions workflow needed to enforce AgentScore Policy Gate for a repo. Detects MCP dependencies locally and returns the OIDC-based YAML needed for setup. No API key or secret is required.
install_policy_gate
Write the AgentScore Policy Gate workflow file to this repo. Creates .github/workflows/agentscore-policy-gate.yml with OIDC authentication (no API key needed). Detects MCP dependencies and includes them in the workflow. The gate will auto-provision the repo on first push.
