 **Postgres MCP Pro** is an open source Model Context Protocol (MCP) server built to support you and your AI agents throughout the **entire development process**—from initial coding, through testing and deployment, and to production tuning and maintenance.
 
-Postgres MCP Pro does much more than wrap a database connection.
+This **TRUF.NETWORK enhanced version** includes specialized tools for blockchain data analysis and stream processing, in addition to all standard PostgreSQL capabilities.
 
-Features include:
+### Core Features
 
 - **🔍 Database Health** - analyze index health, connection utilization, buffer cache, vacuum health, sequence limits, replication lag, and more.
 - **⚡ Index Tuning** - explore thousands of possible indexes to find the best solution for your workload, using industrial-strength algorithms.
 - **📈 Query Plans** - validate and optimize performance by reviewing EXPLAIN plans and simulating the impact of hypothetical indexes.
 - **🧠 Schema Intelligence** - context-aware SQL generation based on detailed understanding of the database schema.
 - **🛡️ Safe SQL Execution** - configurable access control, including support for read-only mode and safe SQL parsing, making it usable for both development and production.
 
+### TRUF.NETWORK Enhanced Features
+
+- **📊 Stream Analytics** - Query composed and primitive stream records with advanced time-series capabilities
+- **📈 Index Calculations** - Calculate percentage changes and analyze stream performance over time
+- **🏗️ Taxonomy Intelligence** - Navigate hierarchical stream relationships and compositions
+- **⚡ Real-time Queries** - Access live blockchain data through optimized recursive CTEs
+- **🔐 Network Security** - Built-in access controls and safe query execution for production blockchain data
+
 Postgres MCP Pro supports both the [Standard Input/Output (stdio)](https://modelcontextprotocol.io/docs/concepts/transports#standard-input%2Foutput-stdio) and [Server-Sent Events (SSE)](https://modelcontextprotocol.io/docs/concepts/transports#server-sent-events-sse) transports, for flexibility in different environments.

+
+### Example Usage Scenarios
+
+Ask your AI agent questions like:
+- "What's the latest calculated value for stream X from data provider Y?"
+- "Show me the percentage change in index values over the last week"
+- "Analyze the composition and weights of this hierarchical stream"
+- "Compare performance metrics between different stream types"
+
+### Database Schema Support
+
+The enhanced version includes optimized support for TRUF.NETWORK's `main` schema with tables:

 *Why are MCP tools needed when the LLM can reason, generate SQL, etc?*
 LLMs are invaluable for tasks that involve ambiguity, reasoning, or natural language.
 When compared to procedural code, however, they can be slow, expensive, non-deterministic, and sometimes produce unreliable results.
