Optional Ed25519 signing
Offline drift verification
Runtime MCP proxy enforcement
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).
Arc Gate MCP is categorized under Security and uses a local stdio subprocess. In contrast, Truecopy belongs to Security using local stdio subprocess. Select Arc Gate MCP when you need capabilities focused on security and Truecopy when you require tools for security.
Runtime governance for MCP tool calls. Blocks prompt injection and capability abuse before tool results reach your agent.
Supply-chain gate for agent skills and MCP servers — scans tool definitions for poisoned instructions, pins vetted servers by content hash in a committed lock, and verifies drift in CI; the bundled truecopy-mcp proxy exposes only pinned, unmodified tools from a live server.
