Gsep Mcp
Harden autonomous coding agents with GSEP’s C3 firewall, C4 immune layer, C5 action guard, and evolving prompts before they touch production systems or spend credentials.
Overview
gsep-mcp is a MCP server for the Ship phase that adds C3 firewall, C4 immune system, C5 action guard, and self-evolving prompts to secure AI agents.
What is this MCP server?
- C3 firewall, C4 immune system, and C5 action guard for AI agents
- Self-evolving prompt defenses bundled in the security stack
- npm package @gsep/mcp v1.0.2 with stdio MCP transport
- LLM backend choice via ANTHROPIC_API_KEY, OPENAI_API_KEY, or OLLAMA_HOST
- GSEP_PRESET intelligence tiers: minimal, standard, conscious, full (default full)
- npm package @gsep/mcp version 1.0.2
- Server registry version 1.0.0
- Four GSEP_PRESET values: minimal, standard, conscious, full
What problem does it solve?
Autonomous agents can exfiltrate context, accept malicious instructions, or run unsafe actions once MCP tools are enabled.
Who is it for?
Solo builders running Claude Code or similar with broad tool access who need defense-in-depth before production.
Skip if: Static sites or manual-only workflows with no autonomous agent execution.
What do I get? / Deliverables
Running GSEP MCP between your client and models gives layered blocking and guarded actions so you can ship agent workflows with tighter boundaries.
- Layered C3/C4/C5 protections on agent traffic and actions
- Configurable GSEP_PRESET security-intelligence profile for your stack

How it compares
Agent runtime security MCP, not a dependency vulnerability scanner or cloud IAM console.
Common Questions / FAQ
Who is io.github.gsepcore/gsep-mcp for?
Indie developers and small teams deploying MCP-enabled coding agents who want firewall, immune, and action-guard controls in the loop.
When should I use io.github.gsepcore/gsep-mcp?
Use it in Ship security review when agents can call tools, mutate repos, or use secrets and you need presets from minimal to full.
How do I add io.github.gsepcore/gsep-mcp to my agent?
Install @gsep/mcp from npm, configure stdio in your MCP client, and set ANTHROPIC_API_KEY or OPENAI_API_KEY or OLLAMA_HOST plus optional GSEP_PRESET.
