 ## The Problem
 
-MCP is revolutionizing how AI agents use tools, but it has created a massive challenge for organizations:
+MCP changes how AI agents use tools, but it has created two critical challenges:
 
+### Problem 1: Management Chaos
 - **Credential Sprawl**: Developers copy and paste sensitive API keys and tokens into insecure local configuration files, creating a huge security risk.
 - **No Governance**: Who is using which tools? Which agent is accessing sensitive customer data? Without a central control plane, companies are blind.
 - **Developer Friction**: Developers spend hours managing complex configurations for dozens of tools, a process that is both tedious and error-prone. Onboarding a new developer is a nightmare of configuration management.
 - **Inconsistent Environments**: Every developer has a slightly different local setup, leading to "it works on my machine" problems and configuration drift.
 
-DeployStack was built to solve these problems head-on.
+### Problem 2: Context Window Consumption Crisis
+- **Token Bloat**: Each MCP server adds 5-15 tools to context. With 10 servers, that's 75,000+ tokens consumed before any work begins.
+- **Performance Degradation**: LLM accuracy drops significantly after 20-40 tools are loaded.
+- **Hard Limits**: Tools like Cursor enforce a 40-tool maximum, forcing developers to disable useful servers.
+- **Cannot Scale**: Teams hit performance walls when trying to use more than 5-8 MCP servers simultaneously.
+
+**Real-world example**: Claude Code users report 82,000 tokens (41% of context window) consumed by MCP tools at startup, leaving only 6% for actual work.
+
+DeployStack solves both problems with a complete MCP management platform and intelligent context window optimization.

+## Key Features
+
+### 🎯 Intelligent Context Window Optimization
+
+DeployStack includes a **hierarchical router** that reduces MCP token consumption by 90%+:
+
+**Traditional Approach:**
+- 10 MCP servers × 15 tools = 150 tools loaded
+- 150 tools × 500 tokens = 75,000 tokens consumed
+- Result: 37.5% of context window gone before you start
+
+**DeployStack Hierarchical Router:**
+- Exposes only 2 meta-tools: `discover_mcp_tools` and `execute_mcp_tool`
+- 2 tools × 175 tokens = 350 tokens consumed
+- Result: 0.175% of context window used
+- **Token Reduction: 99.5%** ✅
+
+**How it works:**
+1. LLM calls `discover_mcp_tools(query)` - "Find GitHub tools"
+2. Router searches across all team MCP servers, returns relevant tool paths
+3. LLM calls `execute_mcp_tool(path, args)` with selected tool
+4. Router executes the actual MCP tool and returns results
+
+This means you can scale from 3 to 100+ MCP servers without degrading LLM performance.
+
+### 🚀 Zero Installation Experience
+
+**Before DeployStack:**
+```bash
+npm install -g some-mcp-cli
+some-mcp configure --api-key=xxx
+# Repeat for every tool, every developer
+```
+
+**After DeployStack:**
+```json
+{
+  "mcpServers": {
+    "deploystack": {
+      "type": "http",
+      "url": "https://satellite.deploystack.io/mcp"
+    }
+  }
+}
+```
+
+### 🔒 Enterprise Security & Governance

+- **Credential Vault**: Encrypted storage with automatic injection
+- **Team Isolation**: Complete separation between teams
+- **Audit Logging**: Track every tool interaction
+- **Role-Based Access**: Fine-grained permissions
