keephaven-mcp
Your agent's memory, on a box in your house. An MCP server that gives an AI agent a long-term memory stored on a Keephaven, not on a vendor's server.
Works with MCP clients that run local servers, like Claude Desktop, Claude Code and Cursor.
What the agent gets
| Tool | What it does |
|---|---|
memory_write | Save a file, like people/dafarus.md or projects/keephaven.md. Optional etag check so two sessions don't overwrite each other. |
memory_read | Read a file back, with its etag. |
memory_list | List files, optionally under a folder. |
memory_search | Case-insensitive search across files and journal. |
memory_delete | Delete a file. |
journal_append | Add an entry to an append-only journal. The agent can add to it, never edit or delete it. |
journal_read | Read recent journal entries, oldest first. |
memory_status | Name, read-only or not, quota used. |
What the owner keeps
- Each agent gets its own folder and can't see any other agent's.
- You add an agent in Keephaven's Settings > Agents and get a token, shown once. The box stores only a fingerprint of it.
- Revoke cuts the agent off at once. Its files stay until you delete them.
- Set a size limit per agent, or make one read-only.
- If your Keephaven backs up to a second box, the agent's folder is part of that backup, and the backup box refuses every delete. That part isn't tested between two real boxes yet.
Set it up
- On the Keephaven: Settings > Agents > Add an agent. Copy the two values it shows.
- Add the server to your MCP client. For Claude Desktop, in
claude_desktop_config.json:
{
"mcpServers": { "keephaven": { "command": "npx", "args": ["-y", "github:dafarusd/keephaven-mcp"], "env": { "KEEPHAVEN_URL": "http://keephaven-xxxx.local:8790", "KEEPHAVEN_TOKEN": "khm_..." } } } }
For Claude Code:
claude mcp add keephaven -e KEEPHAVEN_URL=http://keephaven-xxxx.local:8790 -e KEEPHAVEN_TOKEN=khm_... -- npx -y github:dafarusd/keephaven-mcp
It installs straight from GitHub, so the first start takes a minute while it builds. Needs Node 20 or newer.
The machine running the agent has to reach the box: same home network, the Keephaven's own Wi-Fi, or your Tailscale tailnet when Remote access is on.
Try it with no box
The box runs one Python file with no dependencies. Run that same file anywhere with Python 3:
python3 agent-memory.py serve --data ./mem --bind 127.0.0.1 --dev-token khm_try-it-locally
Then point the MCP server at http://127.0.0.1:8790 with that token. The file is modules/agent-memory.py in the Keephaven repo.
Status, honestly
- The memory service is built and tested: 22 API tests, and a two-VM NixOS test where the service runs as its own locked-down user and a second machine uses it over the network.
- This MCP server has 7 end-to-end tests: the official MCP client, this server over stdio, and the real memory service.
- It ships in Keephaven Agent Memory, released 2026-10-25 for a Pi 5 and for a USB SSD on a Windows PC: https://keephaven.co/agent-memory. The Pi edition passed its release checks on one Pi 5, the SSD edition on a real drive on a Windows PC. Backup ran from a real Pi 5 (pre-release build) to a PC build in a VM over Tailscale — not yet between two real boxes. Keephaven Home has it too from 2026.10.30, switched off — turn it on in Settings > Agent memory. Photos boxes don't have it.
- Tokens travel in plain HTTP on your home network, like the rest of the box's local pages. Over Tailscale they're encrypted.
Agent skill
skill/keephaven/ is an agent skill (a SKILL.md plus a read-only check.py): how to use a Keephaven as memory, and how to boot one in a VM and report what works. check.py was run against the Photos SSD image booted in QEMU: setup page, then ready, Photos up, Immich 3.0.3.
