Defenter Proxy
Add a semantic security layer in front of AI coding agents and other MCP tools before risky actions run in your workflow.
Overview
Defenter Proxy is a MCP server for the Ship phase that adds real-time semantic security in front of AI coding agents and MCP tool usage.
What is this MCP server?
- stdio MCP server (defenter-proxy v0.0.96) installable via PyPI with uvx runtime hint
- Positions itself as real-time semantic security for AI coding agents and MCP tool calls
- Acts as a proxy-oriented control point rather than a single-purpose app integration
- GitHub source at Defenter-AI/defenter-proxy for self-host and version pinning
- Fits teams wiring multiple MCP servers who want an extra interpretation layer on tool semantics
- Server version 0.0.96 on PyPI package defenter-proxy
- Transport type stdio
- Registry type pypi with runtimeHint uvx
Community signal: 3 GitHub stars.
What problem does it solve?
Connecting powerful coding agents to many MCP tools makes it hard to catch unsafe or unintended tool semantics before they execute.
Who is it for?
Indie builders running Claude Code or Cursor with multiple MCP servers who want an extra semantic security proxy in the toolchain before wider rollout.
Skip if: Teams that only need static secret scanning or who are not yet using MCP-connected coding agents.
What do I get? / Deliverables
After you register Defenter Proxy in your MCP client, agent tool traffic can pass through a dedicated semantic security proxy you version and control like other Ship-phase dependencies.
- Registered stdio MCP server defenter-proxy in your agent config
- Version-pinned security proxy (0.0.96) in the agent toolchain
- Tested agent sessions with tool calls routed through the proxy entry point

How it compares
MCP security proxy integration, not a standalone agent skill or IDE linter.
Common Questions / FAQ
Who is Defenter Proxy for?
It is for developers and solo builders who run AI coding agents with MCP tools and want a proxy layer advertised for real-time semantic security.
When should I use Defenter Proxy?
Use it during the Ship security pass when you are hardening agent workflows, before granting production repos, deploy keys, or sensitive MCP integrations.
How do I add Defenter Proxy to my agent?
Add the stdio server entry for package defenter-proxy (PyPI v0.0.96, uvx runtime hint) to your MCP client config, restart the client, and verify the proxy appears in the tool list.
