Exogram — Personal AI Agent & Workspace

Exogram Open-Core SDK & FastMCP Server (v0.2.0)

Exogram (exogram.ai) is a Personal AI Agent and workspace that understands your whole story across your work, people, and everyday life—coordinating specialist agents, turning plain requests into finished interactive deliverables, and executing real tasks with your approval.

This open-core repository provides the official Python/TypeScript SDKs and MCP bridge (mcp-server-exogram) so external AI tools (Claude, Cursor, Windsurf, VS Code, Google Antigravity) can connect directly into that same Exogram Personal Neural Network, interactive widget engine, and action-approval guardrails.

This open-core repository ships the runnable client libraries, local SQLite WAL engine, FastMCP server, and A2UI Living Tile JSON schemas:

• `python/` (`exogram` v0.2.0) — Python SDK with Zero-Signup Local SQLite WAL Mode (~/.exogram/vault.db) and Cloud API routing (https://api.exogram.ai).
• `typescript/` (`@exogram/sdk` v0.2.0) — TypeScript & Node.js SDK with CJS/ESM/DTS builds and zero-signup local mode.
• `mcp-server/` (`mcp-server-exogram` v0.2.0) — FastMCP Server for Claude Desktop, Cursor, Google Antigravity, and OpenAI Agents.
• `schemas/living-tiles-v5.schema.json` — Canonical JSON Schema for all Composable A2UI Living Tiles and the 6 First-Party Kernels.

60-Second Zero-Signup Quickstart (Local SQLite WAL & Cloud)

Every SDK and MCP tool runs immediately on your machine using an embedded SQLite WAL vault (`~/.exogram/vault.db`) with zero account signup or API key required. When you set EXOGRAM_API_KEY, the exact same code routes to Exogram Cloud (`https://exogram.ai`).

1. Run the Python SDK in 30 Seconds

pip install exogram

Or install directly from source:

pip install git+https://github.com/Richard-Ewing/exogram-sdk.git

from exogram import ExogramClient

Automatically initializes ~/.exogram/vault.db (SQLite WAL) when no API key is set,

or routes to https://api.exogram.ai when api_key="exo_live_..." or EXOGRAM_API_KEY is set.

client = ExogramClient()

1. Store memory claims across Work, People, and Life spheres

record = client.vault.store( "Architecture decision: Production edge deploys to Cloudflare Workers via OpenNext", namespace="work", sphere="Work", confidence=0.98, temporal_horizon="durable_trait", ) print(f"Stored {record.id} | State Hash: {record.state_hash}")

2. Traverse the Personal Neural Network (Infinite-Hop Spreading Activation + HippoRAG 2 PPR)

context = client.neural_network.retrieve( query="How does our production edge deploy?", spheres=["Work", "People", "Life"], max_hops=4, ) print(f"PPR Converged: {context.ppr_converged} | Claims: {len(context.claims)}")

3. Deterministic 0.07ms State-Hash & Instinct Pre-Mutation Action Gate

judgment = client.governance.evaluate_action( agent_id="deployment-sentinel", action_type="deploy_cloudflare_worker", parameters={"service": "exogram-edge", "environment": "production"}, state_hash=context.state_hash, )

if judgment.permitted: receipt = client.actions.execute(judgment.execution_token) print(f"Committed! Ledger Hash: {receipt.ledger_hash}")

Or run the self-contained demo script directly from this repository:

python examples/quickstart_local_and_cloud.py

2. Connect Claude Desktop, Cursor, or Antigravity via FastMCP (<30s)

Option A: Zero-Signup Local SQLite WAL Mode (~/.exogram/vault.db)

{

"mcpServers": { "exogram": { "command": "uvx", "args": ["mcp-server-exogram", "--local"] } } }

Option B: Hosted Exogram Cloud MCP (https://exogram.ai/api/mcp)

{

"mcpServers": { "exogram": { "command": "uvx", "args": ["mcp-server-exogram"], "env": { "EXOGRAM_API_KEY": "exo_live_your_key_here", "EXOGRAM_API_URL": "https://api.exogram.ai" } } } }

3. TypeScript / Node.js Quickstart (@exogram/sdk)

npm install @exogram/sdk

import { ExogramClient } from '@exogram/sdk';

const client = new ExogramClient(); // Zero-signup local mode or pass { apiKey: process.env.EXOGRAM_API_KEY }

const rec = await client.vault.store('Deploy target is Cloudflare Workers Global Edge', { namespace: 'work', sphere: 'Work', confidence: 0.96, });

const context = await client.neuralNetwork.retrieve('What is our deploy target?', { spheres: ['Work', 'People', 'Life'], maxHops: 4, });

const judgment = await client.governance.evaluateAction({ agentId: 'ts-agent', actionType: 'deploy_worker', parameters: { target: 'cloudflare' }, stateHash: context.stateHash, });

if (judgment.permitted && judgment.executionToken) { const receipt = await client.actions.execute(judgment.executionToken); console.log('Committed Ledger Hash:', receipt.ledgerHash); }
