## ✦ Overview

**Synapse** is an open-source Python framework engineered for building reliable, production-grade AI assistants, autonomous multi-tool agents, and enterprise backend services.

Modern AI systems face two core engineering challenges:
1. **Context Grounding**: Pure vector search matches semantic similarity within isolated text chunks, but fails to traverse multi-hop relationships between entities (for example, *which services depend on a database managed by a specific engineering squad*). Synapse solves this by coupling **dense vector search** with **directed relational knowledge graphs** into a unified **Dual-Channel Hybrid RAG** engine.
2. **Tool Execution & Interoperability**: AI frameworks often require brittle parsing glue code, non-standardized schemas, and custom network protocols. Synapse standardizes on Anthropic's **Model Context Protocol (MCP)**, allowing Python functions and external servers to be automatically schema-validated, dynamically discovered, and executed by both backend services and desktop IDEs like Claude Desktop and Cursor.

Synapse integrates inference across self-hosted open-weights models (**Ollama**) and frontier cloud APIs (**Google Gemini**, **OpenAI**), pairing runtime execution with a built-in **Developer Web Inspector** and **3D WebGL Knowledge Graph Visualizer**.

def get_market_quote(ticker: str) -> dict:
    """Fetches real-time price, trading volume, and currency for a financial asset."""
    return {"ticker": ticker.upper(), "price": 182.45, "volume": "54.2M", "currency": "USD"}

market_tools = makeconnectors(name="market_data", tools=get_market_quote)
app = BaseApp(title="MarketAssistant", model=ollama("qwen2.5:0.5b"), connectors=[market_tools])

if __name__ == "__main__":
    app.run(port=8000)
```

<a id="use-cases"></a>
## ✦ Production Use Cases

### Use Case 1: Enterprise Infrastructure & Incident Response Assistant

In production environments, Site Reliability Engineers (SREs) need to query running service metrics and cross-reference documentation, dependencies, and on-call schedules. Vector search alone cannot resolve dependency chains; Synapse traverses graph relations alongside operational runbooks.

```python
from synapse import BaseApp
from synapse.connectors import makeconnectors
from synapse.database import chromadb
from synapse.graph import networkx
from synapse.models import ollama
from synapse.resource import Resource
from synapse.storage import vectorStorage

# 1. Ingest infrastructure documentation and post-mortems
runbooks = Resource("sre_runbooks")
runbooks.add("docs/runbooks/payment_service.md")
runbooks.add("docs/runbooks/redis_cluster.md")

# 2. Define operational telemetry tools
def inspect_service_health(service_name: str) -> dict:
    """Queries Prometheus metrics for error rates, latency percentiles, and pod status."""
    return {
        "service": service_name,
        "status": "degraded",
        "p99_latency_ms": 480.2,
        "error_rate_pct": 3.8,
        "active_pods": 8,
    }

def get_oncall_engineer(team: str) -> dict:
    """Retrieves current primary on-call engineer and escalation contact."""
    return {"team": team, "primary": "alex@enterprise.internal", "escalation": "sre-leads@enterprise.internal"}

ops_connectors = makeconnectors(
    name="infra_controller",
    description="Live infrastructure telemetry and on-call routing",
    tools=[inspect_service_health, get_oncall_engineer],
)

# 3. Configure storage backends and populate relational topology
vector_store = vectorStorage(database=chromadb("data/chroma", embedding="bge-small"))
graph_store = networkx("data/infra_graph.json")

graph_store.add_relation("PaymentService", "DEPENDS_ON", "RedisCluster", source_type="Service", target_type="Service")
graph_store.add_relation("PaymentService", "MAINTAINED_BY", "CheckoutTeam", source_type="Service", target_type="Team")
graph_store.add_relation("RedisCluster", "HOSTED_ON", "K8s-East-Cluster", source_type="Service", target_type="Infrastructure")

# 4. Initialize production assistant
app = BaseApp(
    title="SRE Incident Assistant",
    model=ollama("qwen2.5:0.5b"),
    connectors=[ops_connectors],
    resource=runbooks,
    vector_store=vector_store,
    graph_store=graph_store,
)

if __name__ == "__main__":
    app.run(port=8000)
```

When an engineer asks: *"PaymentService latency is spiking. What does it depend on, and who do we page?"*
1. Synapse extracts the entity `PaymentService`.
2. The Graph channel traverses `PaymentService -> DEPENDS_ON -> RedisCluster` and `PaymentService -> MAINTAINED_BY -> CheckoutTeam`.
3. The Vector channel retrieves relevant remediation steps from `payment_service.md`.
4. The Dispatcher automatically executes `inspect_service_health("RedisCluster")` and `get_oncall_engineer("CheckoutTeam")`.
5. The model streams a complete diagnosis and escalation plan.

---

### Use Case 2: Standalone MCP Tool Server for Claude Desktop & Cursor

When you want to expose custom tools, internal databases, or automation scripts directly to developer IDEs without running an HTTP web server or LLM backend, use `conn.run_mcp()`:

```python
from synapse.connectors import makeconnectors

def execute_safe_sql(query: str) -> dict:
    """Executes read-only SQL queries against the analytical data warehouse."""
    if any(keyword in query.upper() for keyword in ["DROP", "DELETE", "UPDATE", "INSERT", "ALTER"]):
        return {"error": "Write operations are forbidden by security policy."}
    return {
        "status": "success",
        "rows": [
            {"region": "us-east-1", "dau": 1420500, "conversion_rate": 0.042},
            {"region": "eu-central-1", "dau": 985200, "conversion_rate": 0.038},
        ],
    }

def calculate_mrr(active_subscriptions: int, arpu: float) -> dict:
    """Calculates Monthly Recurring Revenue and projected annual run rate."""
    mrr = round(active_subscriptions * arpu, 2)
    return {"mrr_usd": mrr, "arr_usd": round(mrr * 12, 2)}

analytics_connector = makeconnectors(
    name="enterprise_analytics",
    description="Internal data warehouse inspection and revenue analytics",
    tools=[execute_safe_sql, calculate_mrr],
)

if __name__ == "__main__":
    # Boots as a standard Model Context Protocol server over stdio
    analytics_connector.run_mcp(transport="stdio")
```

#### Connect to Claude Desktop or Cursor

Add the connector to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "enterprise_analytics": {
      "command": "python",
      "args": ["/path/to/analytics_server.py"]
    }
  }
}
```

The tools are now instantly available as native function calls inside Claude Desktop and Cursor.

### Use Case 3: Autonomous Workspace Assistant with OAuth Connectors

Aggregate personal workspace data across Gmail and Notion with automated synchronization and entity extraction:

```python
from synapse import BaseApp
from synapse.connectors import GmailConnectors, NotionConnectors
from synapse.database import chromadb
from synapse.graph import networkx
from synapse.models import gemini
from synapse.storage import vectorStorage

app = BaseApp(
    title="Executive Workspace Assistant",
    model=gemini(model="gemini-2.0-flash", api_key="AIzaSy..."),
    connectors=[
        GmailConnectors(),    # Google Workspace OAuth connector
        NotionConnectors(),   # Notion Pages & Databases connector
    ],
    vector_store=vectorStorage(database=chromadb("data/workspace_chroma")),
    graph_store=networkx("data/workspace_graph.json"),
)

if __name__ == "__main__":
    app.run(port=8000)
```

- Synchronize data via background indexing endpoints: `POST /sync/gmail` and `POST /sync/notion`.
- Extracted emails and pages are indexed into ChromaDB and parsed into relational triples (e.g. `Author -> SENT -> Email`, `Document -> MENTIONS -> Project`).

---

<a id="hybrid-rag"></a>
## ✦ Dual-Channel Hybrid RAG Engine

Synapse couples **dense vector search** with a **directed property graph** to eliminate the retrieval failure modes of single-channel systems.

```python
from synapse.database import chromadb
from synapse.graph import networkx
from synapse.rag import HybridRAG
from synapse.storage import vectorStorage

# 1. Initialize persistent backends
vector_db = vectorStorage(database=chromadb("data/chroma", embedding="bge-small"))
graph_db = networkx("data/knowledge_graph.json")

# 2. Add relational topology
graph_db.add_relation("Alice Chen", "DIRECTS", "Core Infrastructure", source_type="Person", target_type="Department")
graph_db.add_relation("Core Infrastructure", "OWNS", "Authentication Service", source_type="Department", target_type="System")
graph_db.add_relation("Authentication Service", "USES", "Vault Secrets Engine", source_type="System", target_type="Tool")

# 3. Query combined knowledge base
rag = HybridRAG(vector_store=vector_db, graph_store=graph_db)
context = rag.retrieve_context("Who directs the team responsible for the Authentication Service?")

print("Detected Entities:", context["entities_detected"])
print("Relational Graph Triples:", context["graph_facts"])
```

### Retrieval Context Injected into Prompts

```text
### RELATIONAL KNOWLEDGE GRAPH FACTS:
- Alice Chen -> DIRECTS -> Core Infrastructure
- Core Infrastructure -> OWNS -> Authentication Service
- Authentication Service -> USES -> Vault Secrets Engine

### RELEVANT DOCUMENT EXCERPTS:
1. [CORE_INFRA - Team Roster]
The Core Infrastructure department manages platform security, identity, and access management.
```

<a id="mcp-orchestration"></a>
## ✦ Dynamic Tool Orchestration via MCP

Synapse treats tools as first-class schemas adhering to Anthropic's Model Context Protocol (MCP). When you provide Python functions to `makeconnectors`, Synapse:
1. Inspects function type hints and generates strict JSON Schema parameters.
2. Extracts docstrings to generate tool descriptions for LLM function calling.
3. Provides input sanitization, runtime execution, and trace logging.

```python
from synapse.connectors import makeconnectors

def calculate_carbon_footprint(cloud_hours: float, instance_type: str = "c5.xlarge") -> dict:
    """Estimates carbon footprint (kg CO2e) for cloud compute infrastructure workloads."""
    base_factor = 0.045 if "xlarge" in instance_type else 0.020
    emissions = round(cloud_hours * base_factor, 3)
    return {"instance_type": instance_type, "hours": cloud_hours, "kg_co2e": emissions}

# makeconnectors accepts single functions, lists, or dictionaries
cloud_tools = makeconnectors(
    name="cloud_optimizer",
    description="Cloud computing cost and sustainability inspection tools",
    tools=[calculate_carbon_footprint],
)

# Export as a FastMCP server or run as standalone MCP
mcp_server = cloud_tools.to_mcp_server()
```

---

<a id="models"></a>
## ✦ Pluggable Inference Providers

Synapse abstracts LLM inference behind a unified streaming interface with support for local daemons and frontier cloud providers:

```python
from synapse.models import ollama, gemini, openai

# 1. Local open-weights model via Ollama (zero network dependencies)
local_brain = ollama(model="qwen2.5:0.5b", base_url="http://127.0.0.1:11434")

# 2. Frontier reasoning via Google Gemini
gemini_brain = gemini(model="gemini-2.0-flash", api_key="AIzaSy...")

# 3. OpenAI / compatible endpoints (vLLM, Groq, Together)
openai_brain = openai(model="gpt-4o", api_key="sk-...", base_url="https://api.openai.com/v1")
```

Switch models across any `BaseApp` without changing tool signatures, prompt templates, or storage backends.

---

<a id="storage"></a>
## ✦ Pluggable Storage & Graph Architecture

Synapse provides architectural freedom with zero vendor lock-in. Pick between in-memory testing, local file persistence, or distributed enterprise clusters:

```python
from synapse.database import in_memory, chromadb, qdrant, pgvector
from synapse.graph import in_memory_graph, networkx, neo4j
from synapse.storage import vectorStorage

# Tier 1: Ephemeral In-Memory (Zero disk writes, pure RAM execution)
ram_vector = vectorStorage(database=in_memory(embedding="bge-small"))
ram_graph = in_memory_graph()

# Tier 2: Persistent File-Based (ChromaDB + NetworkX JSON)
file_vector = vectorStorage(database=chromadb("data/chroma", embedding="bge-small"))
file_graph = networkx("data/knowledge_graph.json")

# Tier 3: Distributed Enterprise Cluster (Qdrant + Neo4j)
cluster_vector = vectorStorage(database=qdrant(url="https://qdrant.internal.net", api_key="sk-..."))
cluster_graph = neo4j(uri="bolt://neo4j.internal.net:7687", auth=("neo4j", "password"))
```

---

<a id="skills"></a>
## ✦ Agent Skills & Personas

Skills encapsulate domain knowledge, behavioral instructions, and evaluation guidelines into standardized `SKILL.md` documents. Registered skills are automatically exposed as callable MCP Prompts.

```python
from synapse import BaseApp
from synapse.skills import load_premade_skill, list_premade_skills, makeskills

# 1. Inspect bundled premade skills
print(list_premade_skills())
# Output: ['rag-analyst', 'knowledge-graph', 'mcp-orchestrator', 'mlflow-evaluator', 'template']

# 2. Load pre-packaged skill sets
rag_analyst = load_premade_skill("rag-analyst")
kg_specialist = load_premade_skill("knowledge-graph")

# 3. Create a specialized domain persona from scratch
security_reviewer = makeskills(
    name="Application Security Auditor",
    description="Audits source code and API configurations for OWASP Top 10 vulnerabilities",
    prompt="""
    You are an expert Application Security Auditor.
    When analyzing code or architectures:
    1. Check for command injection, broken authentication, and SSRF.
    2. Flag insecure cryptography or hardcoded secrets.
    3. Require parameterized queries for all database operations.
    """.strip(),
    tags=["security", "audit", "owasp"],
)

# 4. Attach skills to BaseApp
app = BaseApp(skills=[rag_analyst, kg_specialist, security_reviewer])
```

---

<a id="telemetry"></a>
## ✦ MLflow Experiment Tracking & Telemetry

Monitor production latency, evaluate retrieval quality, and track prompts, token throughput, and graph snapshots directly within MLflow:

```python
from synapse import BaseApp
from synapse.telemetry import MLflowTracker

# Automated tracking on all /chat turns:
app = BaseApp(
    title="Customer Operations Assistant",
    mlflow_tracking=True,
    mlflow_experiment="customer_ops_production",
)

# Standalone experiment evaluation:
tracker = MLflowTracker(experiment_name="rag_chunk_evaluation")

with tracker.start_run(run_name="bge_small_top4"):
    tracker.log_params({"embedding": "bge-small", "top_k": 4, "model": "qwen2.5:0.5b"})
    tracker.log_metrics({"latency_ms": 32.4, "chunks_retrieved": 4, "graph_triples": 3})
    tracker.log_artifact("data/knowledge_graph.json")
```

<a id="deployment"></a>
## ✦ Deployment Paradigms: `app.run()` vs `conn.run_mcp()`

Synapse supports two primary execution paradigms:

| Architectural Dimension | `app.run()` (Full Assistant Service) | `conn.run_mcp()` (Standalone MCP Server) |
| :--- | :--- | :--- |
| **System Role** | Complete AI backend with brain, storage & HTTP server | Specialized tool server exposed over standard I/O |
| **Inference Engine** | Required (Ollama, Gemini, or OpenAI) | None needed (Host client acts as the brain) |
| **Protocol Transport** | HTTP REST & Server-Sent Events (SSE) | Standard I/O (`stdio`) or SSE via MCP protocol |
| **Developer UI** | Built-in Web Inspector (`/inspector`) & 3D Graph | Rendered inside client (Claude Desktop / Cursor) |
| **Knowledge Base** | Ingests documents into Hybrid RAG | Attached as MCP Resources / Prompts |
| **Primary Target** | Web applications, custom frontends, enterprise APIs | IDEs (Cursor), desktop apps (Claude Desktop, LibreChat) |
| **Invocation** | `app.run(port=8000)` | `conn.run_mcp(transport="stdio")` |

---

<a id="endpoints"></a>
## ✦ API Reference Specifications

When you boot `BaseApp`, Synapse mounts the following endpoints:

| Method | Endpoint | Category | Description |
