# RCLL MCP Server
|
||
|
||
Standalone [MCP](https://modelcontextprotocol.io) server that exposes **RCLL** memory tools to any MCP-compatible client (Claude Code, OpenClaw, etc). RCLL is self-hosted, hierarchical **shared** memory for a *team* of AI agents — rooms for per-agent vs shared recall, L0–L3 depth, pgvector under the hood.
|
||
|
||
> RCLL — team memory for agent fleets. Built on Hindsight (github.com/vectorize-io/hindsight, MIT).
|
||
|
||
RCLL is a fork of [`vectorize-io/hindsight`](https://github.com/vectorize-io/hindsight) (MIT). It keeps Hindsight's storage engine and adds rooms — shared, isolated memory for a team of agents — plus a hierarchical depth model (L0–L3). The room/hall/layer taxonomy is prior art in the hierarchical-memory space; the implementation here is our own.
|
||
|
||
## Tools
|
||
|
||
| Tool | Description |
|
||
|------|-------------|
|
||
| `memory_retain` | Save memories with room/hall/layer classification |
|
||
| `memory_recall` | Scoped semantic search with room filtering |
|
||
| `memory_reflect` | Deep reasoning + synthesis over stored memories |
|
||
| `memory_compress` | Create closet summaries from accumulated facts |
|
||
| `memory_bridge` | Cross-bank tunnels between related memories |
|
||
|
||
## Quick Start
|
||
|
||
```bash
|
||
cd mcp-server
|
||
npm install
|
||
RCLL_URL=http://localhost:5100 node server.js
|
||
```
|
||
|
||
## Claude Code
|
||
|
||
Add to `~/.claude/mcp.json`:
|
||
|
||
```json
|
||
{
|
||
"mcpServers": {
|
||
"rcll": {
|
||
"command": "npx",
|
||
"args": ["-y", "rcll-mcp"],
|
||
"env": {
|
||
"RCLL_URL": "http://localhost:5100",
|
||
"RCLL_BANK": "my-agent-bank"
|
||
}
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
## Environment Variables
|
||
|
||
| Variable | Default | Description |
|
||
|----------|---------|-------------|
|
||
| `RCLL_URL` | `http://127.0.0.1:5100` | RCLL backend base URL |
|
||
| `RCLL_BANK` | `mempalace-main` | Default memory bank ID. The default keeps the pre-rebrand value on purpose, so an install that never set it stays on the same bank after upgrading. Set it explicitly. |
|
||
|
||
### Deprecated (still read, with a notice on stderr)
|
||
|
||
Installs created before the rebrand keep working — these are used only when the
|
||
`RCLL_*` equivalent is unset, and they will be dropped in a future major.
|
||
|
||
| Legacy variable | Replaced by |
|
||
|-----------------|-------------|
|
||
| `HINDSIGHT_URL` | `RCLL_URL` |
|
||
| `MEMPALACE_BANK` | `RCLL_BANK` |
|
||
|
||
## Memory Taxonomy
|
||
|
||
**Rooms** (topics): auth, pipeline, schema, infrastructure, ui, api, deployment, monitoring, agent, general
|
||
|
||
**Halls** (knowledge types — the `hall` field): fact, event, decision, preference, discovery, procedure, warning
|
||
|
||
**Layers** (depth):
|
||
- L0 — Surface / identity (always at hand)
|
||
- L1 — Critical (recalled by default)
|
||
- L2 — Session (default for new memories)
|
||
- L3 — Deepest burrow / archive (deep search only, compressed into closets)
