synapse-ai-memory 0.13.1

A neuroscience-inspired memory engine for AI agents featuring private vaults, smart inbox review, and natural-language forgetting. Portable, federated, and zero-dependency.

Synapse AI Memory

A local-first memory engine for AI agents. Store facts, context, and conversation history in one place, then retrieve them as structured context with policy + privacy controls.

Current release: 0.13.0

---

Why this release

Recent work focuses on onboarding + runtime + integrations + policy receipts. The repo now provides a cleaner zero-prompt setup path, explicit runtime mode controls, and practical auditability for policy enforcement decisions.

Install

pip install synapse-ai-memory

Optional one-step installer still available:

curl -fsSL https://synapse.ai/install.sh | bash

Quick start (recommended)

# interactive quickstart (flow does onboarding + integration probes)
synapse onboard --flow quickstart

# CI/non-interactive default setup
synapse onboard --flow quickstart --non-interactive --json

# advanced flow with explicit defaults
synapse onboard --flow advanced \
  --policy-template private \
  --default-scope private \
  --default-sensitive on \
  --enable-service \
  --service-schedule daily

Python API is straightforward:

from synapse import Synapse
s = Synapse()
s.remember("I prefer dark mode")
print(s.recall("what theme?"))

Core flow model

• Vault-aware memory: isolate by user_id when enabled.
• Review-first path for sensitive/uncertain captures via the Inbox.
• Natural language forgetting for targeted cleanup.
• Scope + sensitive controls with conservative defaults.
• Portable formats (.brain, checkpoints, imports/exports).
• Federation primitives (synapse federate, sync, push, pull) available when configured.
• Zero-LLM indexing for core recall/ingest.

Runtime and service management

• synapse up --port <port> starts the appliance daemon (MCP stdio server + HTTP JSON-RPC fallback)
• synapse down stops it.
• synapse status shows running status and basic store stats.
• synapse service install|uninstall|status manages autostart (launchd / systemd).

Runtime defaults are local-only; integrations may add network calls only when used.

Integrations (client + contract metadata)

synapse install and synapse integrations are now split by use-case:

# quick probe + integration ops
synapse integrations list --db ~/.synapse
synapse integrations list --json

# install / verify / repair / open flows for detected clients
synapse integrations install claude
synapse integrations test cursor
synapse integrations repair windsurf
synapse integrations open continue

synapse integrations list --json includes connector contract metadata (type, tier, commands, capabilities, doctor_checks, example_prompt) for supported built-ins.

synapse install still handles broader install targets (for example telegram, ollama, nanoclaw) as a direct installer path.

Policy receipts (Phase-1)

Audit trail for permit decisions is now available from policy hooks.

synapse permit receipts --last 5
synapse permit receipts --last 5 --json

Notes:

• Receipts are written to <db>/receipts/permit_receipts.jsonl.
• Schema is stable (synapse.permit.receipt.v1) for JSON output.
• This is a Phase-1 implementation: it records enforcement decisions and reasons, but log volume and retention policies are intentionally minimal.

MCP server

The project exposes MCP tools via:

• synapse serve (default appliance mode)
• synapse serve --http --port 8765 (HTTP JSON-RPC)
• synapse-mcp wrapper (managed launcher at ~/.synapse/bin/synapse-mcp)

Use:

synapse serve                 # local stdio-compatible mode
synapse serve --http --port 8765

For client integrations, see synapse install <client> and the onboarding docs.

Key CLI commands

# onboarding
synapse onboard --flow quickstart
synapse onboard --flow advanced --non-interactive

# integrations & connectors
synapse integrations list --json
synapse integrations install claude
synapse integrations test claude
synapse integrations repair claude

# policy and runtime
synapse permit receipts --last 10 --json
synapse up --port 8765
synapse down
synapse status
synapse service install

# runtime memory operations (examples)
synapse ingest "User prefers concise responses"
synapse clip "Meeting notes: ..."
synapse watch --clipboard
synapse inbox list
synapse nlforget "forget my old job" --dry-run
synapse pack --topic project-x --range 30d

Data model highlights (for API users)

• Contextual recall (Synapse.recall) supports multiple retrieval paths and query options.
• Structured triples + graph indexing are available for explainability and consistency checks.
• Contradiction detection and belief lineage expose confidence/conflicts for recall.
• Scope policy can enforce conservative output behavior at runtime.

Python examples

from synapse import Synapse

s = Synapse("~/.synapse/synapse_store")

# memory with scope
s.remember("Team deadline is Friday", scope="shared", shared_with=["team:ops"])

# compile context for downstream LLM call
pack = s.compile_context("Prepare a concise status update", budget=1800, policy="balanced")
system_prompt = pack.to_system_prompt()

# maintenance + safety
report = s.sleep(verbose=True)
print(report.to_digest())
