Pull request overview
Adds a reusable MemPalace MCP configuration intended to provide persistent, semantic “memory” across workflow runs, and wires it into the daily-fact workflow to avoid repeating previously-posted topics.
Changes:
- Introduces a new shared MCP import (
shared/mcp/mempalace.md) meant to configure and install MemPalace + enablecache-memory. - Updates
daily-fact.mdto query MemPalace before selecting a topic and record the chosen topic after posting. - Regenerates
daily-fact.lock.ymlto include MemPalace MCP server configuration, Python setup, and cache-memory persistence jobs/steps.

- The
pip install "mempalace==3.2.0"step runs in the workflow runner environment, but MCP stdio servers are executed in isolated containers via the gateway. This means the MemPalace package installed here won’t be available to the server process unless the server is also run in that same environment. Consider moving the installation into the MCP server container setup (e.g., using a purpose-built image or an entrypoint that installs dependencies) so the gateway-launched server can actually importmempalace.
steps:
- name: Install MemPalace
run: pip install "mempalace==3.2.0"

- The gateway JSON config for
mempalaceincludes"type": "stdio"with a raw"command": "python". Per the MCP Gateway spec, stdio servers must be containerized andcommandis not supported; the gateway is likely to reject this config or fail to start the server. Update the underlying shared MCP config so this expands to a containerized server (container+entrypoint/entrypointArgs) instead ofcommand.
