Hypermarrow tools (4)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • consolidate

    Merge duplicate memory entries and age out entries older than 90 days. Returns a short summary.

  • file_anchor

    Anchor a short name to an absolute local file path so future queries can resolve "the spec" to the real document.

  • recall_memory

    Recall the most relevant stored contexts given a query. Returns up to 5 ranked entries.

  • record_context

    Capture a piece of local working context (a decision, a fact, a preference) into persistent memory. Nothing is uploaded to the cloud unless HYPERMARROW_ENDPOINT is set.

Install Hypermarrow in Claude Code, Cursor or VS Code

Runs npx -y hypermarrow-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

HyperMarrow MCP Server

Local-first AI memory layer for the Model Context Protocol.

hypermarrow-mcp lets any MCP-compatible client read and write your long-term memory:

  • record_context – remember a decision, fact, or preference
  • recall_memory – retrieve the most relevant past context
  • consolidate – merge duplicates and age out stale entries
  • file_anchor – map a short name to a local file path

All memory lives under ~/.hypermarrow/memory.json on your own machine. Nothing is sent to the cloud unless you explicitly set HYPERMARROW_ENDPOINT to your own backend.

Install

npx -y hypermarrow-mcp

Or add to your MCP client config:

{
  "mcpServers": {
    "hypermarrow": {
      "command": "npx",
      "args": ["-y", "hypermarrow-mcp"]
    }
  }
}

Privacy

Memory data is stored locally. The server only talks to the client over stdio and, optionally, to a user-configured HYPERMARROW_ENDPOINT. No telemetry, no cloud sync by default.

Nothing above is checked by us. What we check is on the safety report.
