What it can do

  • Recall: Retrieve relevant persisted memory using semantic, temporal, priority, or hybrid routing. Governance: requires reason (10–200 chars). Rate limit: 20/min.
  • Save To Synapse: Persist memory with encryption at rest, sanitization, and deduplication controls.
  • Process Text: Extract candidate memories from free-form text with governance filters and sanitization.

What data it sees

Do you need an account

No: the server works without sign-in

Synapse Layer — MCP-native Trust Infrastructure for AI Agents. Persistent encrypted memory at rest with AES-256-GCM, semantic recall, cross-agent continuity, audit-ready. 13 tools, free tier.

How to connect

How to connect Synapse Layer to Claude

The server address to paste into Claude settings:

https://synapselayer.run.tools

  1. Open Claude (claude.ai or the desktop app).
  2. Go to Settings → Connectors.
  3. Click Add custom connector.
  4. Paste the server address copied below into Remote MCP server URL and click Add.
  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

Authorization

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect Synapse Layer to ChatGPT

The server address to paste into ChatGPT settings:

https://synapselayer.run.tools

  1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
  2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
  3. Open Settings → Connectors and click Create.
  4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
  5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
  6. In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

How to connect Synapse Layer to Cursor

The server address to paste into Cursor settings:

https://synapselayer.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

Server tool list (13)

Raw names from tools/list. Only developers need these.

recallRetrieve relevant persisted memory using semantic, temporal, priority, or hybrid routing. Governance: requires reason (10–200 chars). Rate limit: 20/min.
save_to_synapsePersist memory with encryption at rest, sanitization, and deduplication controls.
process_textExtract candidate memories from free-form text with governance filters and sanitization.
searchSearch persisted memory across agent scopes using full-text matching. Governance: requires reason (10–200 chars) because results contain plaintext content.
health_checkCheck service availability, engine version, and storage health. Public method.
initialize_contextInitialize a persistent memory context for a conversation or agent session. Returns REDACTED metadata by default (detail="summary"). Use detail="full" with a reason (10–200 chars) to retrieve plaintext content under MEMORY_EXPORT_GOVERNANCE_V1.
save_memorySave a memory entry to the persistent store. Alias of save_to_synapse.
store_memoryStore structured memory with metadata and trust scoring.
recall_memoryRecall persisted memory by query. Alias of recall.
list_memoriesList memory metadata with pagination and governance limits.
memory_feedbackSubmit feedback to adjust trust scoring for stored memories.
neural_handoverTransfer contextual state between agents with continuity controls.
slo_reportReturn uptime and SLO metrics for the MCP service.
