Synapse Layer — Trust Infrastructure for AI Agents MCP Server

io.github.SynapseLayer/synapse-layer

Persistent encrypted memory for AI agents with semantic search and trust scoring.

What is the Synapse Layer — Trust Infrastructure for AI Agents MCP server?

Synapse Layer is an MCP-native persistent memory infrastructure for AI agents that stores encrypted memories with semantic recall and trust quotient scoring. It enables agents to maintain context across sessions and share memories across different AI platforms like Claude, ChatGPT, and Gemini.

Synapse Layer provides a secure, searchable memory layer for AI agents. Memories are encrypted at rest with AES-256-GCM, indexed for semantic recall via pgvector HNSW, and exposed through MCP JSON-RPC. It solves the problem of stateless LLMs forgetting context between sessions and enables cross-agent memory sharing.

Tools & capabilities

Tools this server exposes to the agent.

  • recall — Retrieve memories via semantic search with trust quotient ranking
  • save_to_synapse — Store a memory in the encrypted persistent layer
  • process_text — Process and prepare text for memory storage
  • search — Search stored memories by content
  • health_check — Check the health status of the Synapse Layer service
  • initialize_context — Initialize context for a new memory session
  • save_memory — Save structured memory entries
  • store_memory — Store memory with metadata
  • recall_memory — Recall specific memories by query

Use cases

  • Persist user preferences and conversation history across multiple chat sessions with different AI models
  • Build multi-agent systems where one agent saves context that another agent can recall and act upon
  • Maintain an audit trail of agent decisions with trust scoring for production AI workflows
  • Create long-term assistant memory that survives session restarts and model switches
  • Implement secure memory sharing across teams using encrypted, tenant-scoped storage

Synapse Layer — Trust Infrastructure for AI Agents MCP server FAQ

What is Synapse Layer?

Synapse Layer is persistent encrypted memory infrastructure for AI agents. It stores memories encrypted with AES-256-GCM, indexes them for semantic recall, and exposes them via MCP so agents like Claude, ChatGPT, and Gemini can access shared context across sessions.

Is Synapse Layer free?

Synapse Layer is open-source under Apache 2.0. You can self-host it or use the managed Forge service at forge.synapselayer.org, which requires a Connect Token obtained from the dashboard.

How do I install it in Claude Desktop or Cursor?

Add the MCP server to your claude_desktop_config.json with the remote endpoint https://forge.synapselayer.org/api/mcp and your Connect Token in the x-connect-token header. The Forge dashboard provides a one-command install via Smithery.

What authentication is required?

You need a Connect Token from forge.synapselayer.org. Tokens are passed via the x-connect-token header (never in URLs) and are required for all API calls.

Can memories be shared across different AI models?

Yes. Memories saved in one agent (e.g., ChatGPT) can be recalled by another (e.g., Claude) if they share the same Connect Token, enabling true cross-agent continuity.

How are memories secured?

Memories are encrypted at rest with AES-256-GCM using per-operation random IVs, integrity-checked with HMAC-SHA-256, and stored in tenant-scoped encrypted storage with header-first authentication.

Persistent memory infrastructure for AI agents — AES-256-GCM encrypted at rest, semantic search, MCP-native.

Synapse Layer is open-source persistent memory infrastructure for AI agents and assistants. Memories are encrypted at rest with AES-256-GCM, indexed via pgvector HNSW for semantic recall, and exposed through MCP JSON-RPC for native integration with Claude, GPT, Gemini, and any MCP-compatible client.

⚡ 30-Second Quickstart

Get your Connect Token at forge.synapselayer.org → Connect, then install into any MCP client:

curl -fsSL https://forge.synapselayer.org/install/smithery | bash

On the Forge dashboard the Smithery card already copies the command with your token embedded (… | bash -s -- sk_connect_…) — a single paste in your terminal is enough.

Or use the Python SDK:

from synapse_layer import Synapse

s = Synapse(token="sk_connect_YOUR_TOKEN")

s.store("user likes coffee")
print(s.recall("what does user like?"))

What is Synapse Layer?

The persistent memory layer for AI agents — the missing piece between stateless LLMs and real continuity of context.

Your AI agents forget everything between sessions. Synapse Layer fixes that.

Use Cases

  • Long-term assistant memory — persist user preferences, facts, and prior decisions across sessions.
  • Cross-agent continuity — save context in one agent and recall it in another.
  • Secure memory for MCP clients — connect Claude Desktop, Cursor, and other MCP-compatible tools to a governed memory layer.
  • Operational memory for teams — maintain structured context, trust scoring, and searchable recall for production agents.

Install

pip install synapse-layer

Quick Start

Python Script

from synapse_layer import Synapse

client = Synapse(token="sk_connect_YOUR_TOKEN")

# Store
client.store("User prefers dark mode and concise answers")

# Recall
results = client.recall("user preferences")
for r in results:
    print(r["content"], r["trust_quotient"])

With Context Manager

from synapse_layer import Synapse

with Synapse(token="sk_connect_YOUR_TOKEN") as client:
    client.store("User prefers dark mode and concise answers")
    results = client.recall("user preferences")
    for r in results:
        print(r["content"])
