🪜 The 6-Stage Agentic AI Roadmap: How PosturePilot Maps Side-by-Side

Most security tools are stuck at Level 1 (Prompting) or Level 2 (RAG). PosturePilot is engineered across all 6 tiers—advancing through Autonomous Agents, Model Context Protocol (MCP), Rigorous Evals, to Multi-Agent Orchestration.

🔌

LEVEL 4 OF 6Standardized Context

MCP (Model Context Protocol)

📂 src/components/McpArchitectureDiagram.tsx, src/app/mcp/page.tsx

🌐 Industry Standard Definition

Anthropic open RFC standard decoupling LLMs from tools and data sources via typed JSON-RPC 2.0.

⚠️ Common Industry Limitation

Custom brittle API wrappers with vendor lock-in that break whenever foundation model providers change.

🛡️ How PosturePilot Implements ItPRODUCTION LIVE

Native PosturePilot MCP Server exposing standardized tools (Tenable, Qualys, Jira, AWS IAM) and URI resource streams (cve://, posture://).

✓Universal model compatibility (Claude 3.5, GPT-4o, Gemini, local Ollama)

✓Typed JSON-RPC 2.0 schema discovery with strict Zod validation

✓Decoupled tool execution engine ensuring zero vendor lock-in

Technologies:@modelcontextprotocol/sdk v1.x • JSON-RPC 2.0 • SSE & stdio transports

Standardizes how AI Copilots discover security tools, inspect vulnerability resources, and execute deterministic remediation.

🧠 Anthropic Claude 3.5 Sonnet

⚡ OpenAI GPT-4o / Gemini 1.5

🔄 LangGraph Multi-Agent Planner

LAYER 2 • PROTOCOL SERVERJSON-RPC 2.0

🔌 PosturePilot MCP Server

Central runtime exposing verified schema tools, posture resources, and enforcing strict human approval gates.

📦 Tools Registry: Dynamic JSON Schema discovery

📂 Resources Provider: cve:// & posture:// URIs

🛡️ Human-in-the-Loop Policy Gate

Transport: Standard I/O (stdio) & Server-Sent Events (SSE)

LAYER 3 • TOOL DISPATCHERS5 Active Handlers

⚡ Deterministic Security Tools

Sandboxed execution units that interact directly with scanners, cloud providers, and ticketing systems.

Execution Lifecycle: How an MCP Security Tool is Called in PosturePilot

1. Tool Discovery

Copilot queries tools/list. MCP Server returns JSON Schema specs for all 5 security endpoints.

2. ReAct Decision

Agent formulates reasoning, builds typed input payload matching target tool schema, and issues tools/call.

3. Policy & Approval

If tool mutates state (e.g., AWS IAM isolation or Jira ticket), MCP Server halts and triggers CISO approval prompt.

4. Context Enrichment

Tool executes against downstream API, normalizes response into standard JSON-RPC envelope, and updates Posture score.
