Getting Started¶

This guide takes you from a fresh Python environment to a running JarvisCore agent in under ten minutes. It covers installation, initial configuration, and your first working agent.

Requirements¶

JarvisCore requires Python 3.10 or later. No infrastructure is required to run a minimal agent — the first working example in this guide uses only an LLM API key.

Optional: Docker is required for two capabilities:

jarviscore nexus up — starts the local Nexus broker and gateway for OAuth2 credential management
jarviscore-framework[browser] — Playwright runs in a Docker-managed Chromium for browser automation

If you are not using Nexus or browser automation, Docker is not needed.

Installation¶

pip install jarviscore-framework

To install optional extras for specific capabilities:

P2P MeshWebRedisBrowser AutomationRAGResearchAthena MemoryAzure Blob StoragePrometheus MetricsFull

pip install "jarviscore-framework[p2p]"

Enables distributed multi-node agent deployments via the SWIM gossip protocol and ZMQ transport. Required when P2P_ENABLED=true.

pip install "jarviscore-framework[web]"

Adds FastAPI, Uvicorn, and BeautifulSoup4. Required to run the built-in dashboard, chat endpoints, and FastAPI integration.

pip install "jarviscore-framework[redis]"

Enables distributed workflows, cross-session agent state, and peer routing via Redis. Required when REDIS_URL is set.

pip install "jarviscore-framework[browser]"
playwright install chromium

Enables BrowserSubAgent and Playwright-based web interaction tools. Required when BROWSER_ENABLED=true.

pip install "jarviscore-framework[rag]"

Adds local vector search (FAISS) and sentence-transformers for embedding-backed research and knowledge retrieval.

pip install "jarviscore-framework[research]"

Full researcher stack — installs browser + rag + BeautifulSoup4. Everything ResearcherSubAgent needs for deep web research.

pip install "jarviscore-framework[memory-athena]"

No extra Python dependencies. Athena is called over HTTP. Run the Athena service separately, then set ATHENA_URL=http://localhost:8080.

pip install "jarviscore-framework[azure]"

Adds the Azure Storage Blob client for the registry storage backend and azure_storage atoms.

pip install "jarviscore-framework[prometheus]"

Exposes a /metrics endpoint for operational dashboards and alerting.

pip install "jarviscore-framework[full]"

Installs every optional dependency — use for production deployments where you need all capabilities enabled.

Scaffold Your Project¶

Run jarviscore init to create the initial project structure and a pre-populated .env.example:

jarviscore init

This creates:

.env.example        — environment variable template

Copy the example to create your working configuration:

cp .env.example .env

Configure an LLM Provider¶

JarvisCore supports four LLM providers. Configure exactly one by adding the appropriate variables to your .env file.

Anthropic ClaudeGoogle GeminiAzure OpenAILocal / vLLM

.env

CLAUDE_API_KEY=sk-ant-...
CLAUDE_MODEL=claude-sonnet-4

.env

GEMINI_API_KEY=AIza...
GEMINI_MODEL=gemini-2.0-flash

.env

AZURE_API_KEY=...
AZURE_ENDPOINT=https://your-resource.openai.azure.com/
AZURE_DEPLOYMENT=gpt-4o
AZURE_API_VERSION=2024-02-15-preview

.env

LLM_ENDPOINT=http://localhost:8000
LLM_MODEL=mistral-7b-instruct

Verify Your Installation¶

jarviscore check

This command validates your Python version, package installation, and LLM configuration. To also test live inference against the configured provider:

jarviscore check --validate-llm

Expected output when everything is correctly configured:

  All checks passed. Ready to use JarvisCore.

Your First Agent¶

Create a file named main.py:

main.py

import asyncio
from jarviscore import Mesh, AutoAgent


class ResearcherAgent(AutoAgent):
    name = "Researcher"
    role = "researcher"
    description = "Researches topics and produces concise summaries."
    system_prompt = """
    You are a systematic research analyst. When given a topic,
    you identify the most relevant facts, verify them against
    multiple angles, and summarise your findings clearly.
    """


async def main():
    mesh = Mesh()
    mesh.add(ResearcherAgent)
    await mesh.start()

    result = await mesh.run_task(
        agent="researcher",
        task="What are the main architectural differences between the SWIM and Raft consensus protocols?",
    )

    print(result)


if __name__ == "__main__":
    asyncio.run(main())

Run it:

python main.py

The agent will reason through the task using the OODA loop and return a structured response. Because no infrastructure is configured beyond the LLM key, all state is held in process memory and discarded when the script exits.

Your First Multi-Agent Workflow¶

The following example demonstrates a two-agent pipeline where a Scout gathers raw data and an Analyst processes it.

multi_agent.py

import asyncio
from jarviscore import Mesh, AutoAgent


class ScoutAgent(AutoAgent):
    name = "Scout"
    role = "scout"
    description = "Gathers raw data on a given subject."
    system_prompt = "You gather raw, factual data on the subject provided. Be thorough and cite your sources."


class AnalystAgent(AutoAgent):
    name = "Analyst"
    role = "analyst"
    description = "Analyses data and produces structured intelligence reports."
    system_prompt = "You receive raw research data and produce a structured intelligence report with clear conclusions."


async def main():
    mesh = Mesh()
    mesh.add(ScoutAgent)
    mesh.add(AnalystAgent)
    await mesh.start()

    # Step 1: Scout gathers raw data
    raw_data = await mesh.run_task(
        agent="scout",
        task="Gather data on the current state of vector database technology.",
    )

    # Step 2: Analyst processes the raw data
    report = await mesh.run_task(
        agent="analyst",
        task=f"Analyse the following research data and produce a structured report:\n\n{raw_data}",
    )

    print(report)


if __name__ == "__main__":
    asyncio.run(main())

Next Steps¶

Once you have a working agent, add infrastructure incrementally based on your requirements.

Add persistent memory so agents retain context across runs:

docker run -d -p 6379:6379 redis:7-alpine

.env

REDIS_URL=redis://localhost:6379/0

Add cross-session semantic memory with Athena:

jarviscore memory init

Add third-party service credentials for agents that call external APIs:

jarviscore nexus init
jarviscore nexus register github --client-id=YOUR_ID --client-secret=YOUR_SECRET

Enable multi-node distributed execution with P2P:

.env

P2P_ENABLED=true
JC_SWIM_PORT=7946

See the Configuration Reference for the complete list of environment variables and their defaults.
