Memory MCP

A persistent, cross-provider memory server using FastMCP, Langchain, and Postgres.

Features

• MCP Server that agents can use to store facts about the user

• Transferrable across providers - usable across multiple agents

• Compatible with any MCP-capable agent (Claude Desktop, Claude Code, Opencode, etc.)

• Backed by Postgres to ensure data persistence and scalability

• Support multiple users from a single server

• Exposes two tools to your agent:

  • search_memory: Search the database for memories about the user

  • upsert_memory: Add/update memories for the user

Related MCP server: brain-mcp

Prerequisites

• Docker/Podman compose

• Openshift CLI

Usage

Local

1. Clone the repository:

   git clone https://github.com/taagarwa-rh/memory_mcp.git
   cd memory_mcp

2. Spin up the services:

   # For Podman
   podman compose up -d
   
   # For Docker
   docker compose up -d

   The MCP server will now be available at http://localhost:1313/mcp

Openshift

1. (Optional) Update the postgres username and password in secret.yaml

2. Deploy the resources

   oc apply -n <your-namespace> -f deploy

3. Fetch the route:

   ROUTE=$(oc get route memory-mcp -o jsonpath='{.spec.host}')
   ROUTE="https://$ROUTE/mcp"
   echo $ROUTE

Claude Code

claude mcp add --transport http memory https://<mcp-route>/mcp --header "X-User-Id: <your-username>"

OpenCode

opencode mcp add

Location: Either Name: memory Type: Remote URL: https:///mcp

Then in your opencode.json, add the user ID header:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "memory": {
      "type": "remote",
      "url": "https://<mcp-route>/mcp",
      "headers": {
        "X-User-Id": "<your-username>"
      }
    }
  }
