Self-hosted long-term memory for AI agents over MCP — hierarchical recall backed by pgvector

VerifiedSTDIODesktop onlyKnowledge & Memory

Overview

AI-generated overview

Self-hosted long-term memory for AI agents: lets an assistant retain and recall memories from a Hindsight server backed by pgvector.

What you can do
  • Retain information into a memory bank on a self-hosted Hindsight API.
  • Recall stored memories, with hierarchical recall backed by pgvector.
  • Select which memory bank to use for retain and recall operations.
  • No individual tools are listed in the manifest, so exact operations are not documented here.
When to use it
Useful when you want an assistant to keep persistent, long-term memory across sessions and you already run (or are willing to run) your own Hindsight instance rather than a hosted memory service.
Requirements
Runs locally as a stdio process via npx (Node.js). Needs a reachable self-hosted Hindsight API, set through HINDSIGHT_URL (defaults to and a default memory bank ID via MEMPALACE_BANK. Desktop client only; no authentication is declared.
Before you install
Memories are written to and read from your own Hindsight instance, so anything retained is stored there; review what the assistant saves. The default endpoint is plain HTTP on localhost, so point HINDSIGHT_URL only at a server you trust. No authentication is declared, so protect the Hindsight API yourself.

Installation

In SourceWeft

  1. Open Hindsight MemPalace in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
