Mempalace Http

HTTP transport for mempalace-mcp. One palace, many machines.

Prerequisites

mempalace must already be installed on the target machine:

uv tool install mempalace   # or: pip install mempalace

This tool extends mempalace — does not replace or install it.

Setup

curl -fsSL https://raw.githubusercontent.com/flejz/mempalace-mcp-http/master/setup.sh | bash

Or clone and run:

git clone https://github.com/flejz/mempalace-mcp-http
cd mempalace-mcp-http
./setup.sh

Detects mempalace, installs HTTP deps, configures systemd service. If ~/.claude/settings.json exists, prompts to add (or replace existing mempalace entry with) the HTTP MCP config automatically.

Token management

mempalace-token is installed to ~/.local/bin/ during setup:

mempalace-token show      # masked preview
mempalace-token reveal    # full token
mempalace-token rotate    # new token + restart service
mempalace-token remove    # invalidate token — blocks all clients

remove replaces the token with an unguessable value (server stays auth-required, no valid token exists). Use rotate to recover access.

Claude Code config

Setup auto-configures via claude mcp add with a confirmation prompt. Manual command on any machine:

claude mcp add --transport http mempalace \
  http://<palace-host>:8765/mcp \
  --header "Authorization: Bearer <token>"

Replaces the standard stdio entry (python -m mempalace.mcp_server) — setup.sh detects it and prompts automatically.

For non-Claude clients, equivalent settings.json entry:

{
  "mcpServers": {
    "mempalace": {
      "type": "http",
      "url": "http://<palace-host>:8765/mcp",
      "headers": { "Authorization": "Bearer <token>" }
    }
  }
}

Env vars

Var	Default	Purpose
MEMPALACE_HTTP_PORT	8765	Listen port
MEMPALACE_HTTP_HOST	0.0.0.0	Bind address
MEMPALACE_HTTP_TOKEN	(unset = open)	Bearer auth token

How it works

• Calls mempalace.mcp_server.handle_request() directly — no subprocess, no protocol proxying
• threading.Lock serializes all calls — sqlite-safe under concurrent clients
• 1:1 tool mapping — all mempalace tools available, auto-updated when mempalace upgrades

Health check

curl http://localhost:8765/health
# {"status":"ok","mempalace":"3.x.x"}
