Exogram Open-Core SDK & FastMCP Server (v0.2.0)
Exogram is the Personal Neural Network (Work · People · Life), Encrypted Memory Vault, and Deterministic Action Governance Engine for AI agents.
This open-core repository ships the runnable client libraries, local SQLite WAL engine, FastMCP server, and A2UI Living Tile JSON schemas:
python/(exogramv0.2.0) — Python SDK with Zero-Signup Local SQLite WAL Mode (~/.exogram/vault.db) and Cloud API routing (https://api.exogram.ai).typescript/(@exogram/sdkv0.2.0) — TypeScript & Node.js SDK with CJS/ESM/DTS builds and zero-signup local mode.mcp-server/(mcp-server-exogramv0.2.0) — 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);
}

The 6 First-Party Cognitive Kernels
Every turn is orchestrated by six specialized first-party kernels and audited by verifyAgentContributionsAgainstTurnOutput so only kernels whose outputs are genuinely cited in the final synthesis display Complete · Cited:
| Kernel | Responsibility |
|---|---|
Neural Graph Kernel |
Traverses multi-hop associative paths across Work, People, and Life using Spreading Activation and HippoRAG 2 Spectral PPR. |
Generative UI Kernel |
Synthesizes and validates Composable A2UI Living Tiles against schemas/living-tiles-v5.schema.json. |
Live Web & Places Scout |
Executes PII-stripped public web & place verification for PUBLIC_ONLY subtasks. |
Action & Draft Kernel |
Prepares governed emails, calendar events, and external tool mutations gated by the 0.07ms Instinct Action Gate. |
Analytical Synthesis Kernel |
Performs multi-constraint reasoning, tradeoff matrices, and structured comparisons. |
Grounded Citation Kernel |
Enforces contrastive claim-predicate entailment (scoreClaimPredicateEntailment) and Perplexity-style [1], [2] citations. |
