# PyStreamMCP

**The Open Intelligence Layer for AI Agents**

[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](LICENSE)
![Version: v0.4.0](https://img.shields.io/badge/Version-v0.4.0-blue)
![OKF: Native](https://img.shields.io/badge/OKF-Native-green)
![Status: Production Ready](https://img.shields.io/badge/Status-Production%20Ready-brightgreen)

PyStreamMCP is a Rust-powered, Python-extensible platform that optimizes queries and discovers context for AI agents. It delivers **60-75% token reduction** while maintaining quality and speed—now with **native OpenKnowledge Format (OKF) support** for transparent, portable, community-driven metadata.

## Philosophy

Rather than agents asking for everything and parsing the response, PyStreamMCP asks: **What does this agent actually need?**

```
Agent Query
        ↓
OKF System Discovery (know available systems)
        ↓
Query Planning (token budget)
        ↓
Context Discovery (what's relevant?)
        ↓
Cost-Aware Optimization (60-75% reduction)
        ↓
Optimal Context Window
        ↓
Agent Response (with full transparency)
```

The platform sits between agent frameworks and data systems as a **transparent, open intelligence layer**—dramatically reducing token usage while keeping metadata portable, auditable, and community-improvable.

## Core Capabilities

### 🗂️ Open Knowledge Discovery (OKF-Native)
- **Portable System Metadata** — MCP systems defined as git-tracked markdown
- **Agent-Native Catalog** — Agents discover tools directly from OKF documents
- **Zero Vendor Lock-in** — Metadata not trapped in any proprietary format
- **Community-Driven** — Teams submit PRs to improve tool definitions
- **Cost Transparency** — Every tool has auditable cost, latency, and success profiles
- **System Relationships** — Understand interconnections between data systems

### Query Planning
- Understand agent intent (Retrieve, Discover, Aggregate, Synthesize, Analyze)
- Enforce token budgets per query
- Set latency and confidence constraints
- Token-efficient mode (500 token cap, 0.85 confidence floor)
- **OKF-driven routing** — Select optimal systems based on cost/latency trade-offs

### Context Discovery
- Identify relevant data sources automatically (from OKF catalog)
- Rank by relevance + freshness + cost scores
- Estimate token cost per source (from OKF metadata)
- Discover across warehouses, caches, APIs
- **Pattern-aware** — Learn from historical query costs

### Cost Optimization
- **Caching** — Reuse computed results
- **Summarization** — Summarize instead of full text
- **Sampling** — Sample data instead of full scan
- **Pruning** — Remove low-relevance items
- **Compression** — Compress representations
- **Async** — Parallelize requests
- **Early Termination** — Stop when confident
- **OKF-optimized routing** — Use cost profiles from metadata

### Validation Gates
- Integrate StatGuardian for data quality
- Validate context before including in responses
- Configurable freshness requirements
- Block bad data automatically
- **Auditable decisions** — Full trace of optimization choices in OKF

## Getting Started

### Installation

```bash
pip install pystreammcp
```

### Quick Example: OKF-Powered Query Optimization

```python
from pystreammcp.okf_core import OKFCatalog
from pystreammcp.okf_query_planner import OKFQueryPlanner

# Load your system metadata (stored as portable markdown)
catalog = OKFCatalog(Path("./mcp_catalog"))

# Plan optimal query paths from cost metadata
planner = OKFQueryPlanner(catalog)

# Find cheapest path to answer agent's question
plan = planner.find_cheapest_path("customer churn risk analysis")

# Execute plan with full transparency
for step in plan.steps:
    print(f"System: {step.system_name}, Cost: ${step.cost}, ETA: {step.latency_ms}ms")

# Result: Optimized plan with 60-75% token reduction
# Bonus: Full audit trail of optimization decisions
```

### OKF System Catalog

PyStreamMCP now includes native OKF support—your system metadata lives in git, not in binary files:

```
mcp_catalog/
├── systems/              # Postgres, Elasticsearch, BigQuery, etc.
├── tools/                # Search, Query, Analytics endpoints
├── query_plans/          # Optimized retrieval plans
└── interconnections/     # System relationships & data flows
```

Each system is a markdown file with cost, latency, and success profiles—**agent-navigable, community-improvable, vendor-agnostic**.

## Core Concepts

### Queries
What agents need to know:
- **Retrieve** — Get specific information
- **Discover** — Explore available data  
- **Aggregate** — Summarize multiple sources
- **Synthesize** — Combine information
- **Analyze** — Statistical analysis

### Context
Relevant information discovered automatically:
- Entity data (customers, accounts, products)
- Relationships (who knows whom, what links where)
- Metrics (MRR, churn rate, engagement)
- Historical context (trends, patterns)
- Similar items (recommendations, benchmarks)
- Contextual information (categories, tags)

### Discovery
Find what matters:
- Scan available data sources
- Rank by relevance + freshness
- Estimate token costs
- Identify caching opportunities
- Discover relationships and dependencies

### Optimization
Reduce without losing quality:
- 60-75% token reduction target
- Multiple techniques combined
- Quality validation throughout
- Cost metrics tracked

## Features

### ✅ Phase 1: Intelligence Foundation

## OKF: The Open Intelligence Advantage

PyStreamMCP is the **first query optimizer to make system metadata portable and community-improvable**.

| Capability | Traditional Query Optimizers | PyStreamMCP + OKF |
|---|---|---|
| **Portability** | Locked in proprietary format | Git-trackable markdown |
| **Discovery** | API-dependent | Agents read markdown directly |
| **Cost Tracking** | Black box | Auditable metadata |
| **Community** | Closed | Pull request-driven improvement |
| **Vendor Lock-in** | High | Zero (OKF is open standard) |
| **Compliance** | Opaque decisions | Full decision audit trail |
| **Integration** | Custom code | Native OKF catalog |

**Real-World Impact:**
- Metadata syncs automatically with your team's system changes
- New systems added? Just submit a PR to `mcp_catalog/systems/`
- Cost profiles improve as your team contributes historical data
- Agents make smarter decisions because metadata is always current
- Easy to validate: "Show me the OKF justification for this query plan"

---

## Token Reduction Targets

PyStreamMCP aims for 60-75% token reduction:

**Before (Traditional Query):**
- Query: "Which customers are at churn risk?" (10 tokens)
- Full customer data: 2,000 rows × 50 tokens = 100,000 tokens
- Full interaction history: 500 interactions × 20 tokens = 10,000 tokens
- Similar customers: 100 rows × 50 tokens = 5,000 tokens
- **Total: 115,010 tokens**

**After (with PyStreamMCP + OKF):**
- Query: "Which customers are at churn risk?" (10 tokens)
- Top 10 at-risk customers + key traits (from OKF cost-optimal path): 500 tokens
- Recent interactions (last 30 days, parallelized): 1,000 tokens
- Cohort comparison (cached from previous queries): 500 tokens
- **Total: 2,010 tokens**
- **Reduction: 98.3% (exceeds 60-75% target)** ✅
- **Bonus: Full transparency** — Each decision traced back to OKF system metadata

## Ecosystem

PyStreamMCP is part of the data intelligence platform:

- **StatGuardian** — Ensures data is trustworthy (validation, contracts, drift)
- **ClusterAudienceKit** — Identifies who matters (segmentation, clustering)
- **PyReverseETL** — Activates intelligence in operational systems
- **PyCustomerJourney** — Drives engagement through journeys
- **PyStreamMCP** — Optimizes intelligence for AI agents (this project)

## Architectural Boundaries

PyStreamMCP focuses exclusively on:

✓ Query planning and optimization
✓ Context discovery
✓ Cost optimization (token reduction)
✓ Agent intelligence

PyStreamMCP does NOT:

✗ Validate data (StatGuardian)
✗ Create audiences (ClusterAudienceKit)
✗ Activate data (PyReverseETL)
✗ Manage journeys (PyCustomerJourney)
