Rememb MCP server

<!-- mcp-name: io.github.LuizEduPP/rememb -->

Operate AI agents without losing context between sessions. rememb is a local-first persistent memory layer: structured entries, keyword search, versioning, diff, restore, and audit trail — no cloud service required.

The problem

Teams using agents at real velocity rarely fail because they lack generation. They fail because operating agents every day creates context debt:

• too much re-explaining project facts every session
• too little durable memory outside the chat window
• too little audit trail for why something changed
• too much noise when recalling the right context

Every team or solo developer operating agents professionally hits this wall:

Session 1: "We're using PostgreSQL, auth at src/auth/, prefer async patterns."
Session 2: Agent starts from zero. You explain everything again.
Session 3: Same thing.

Existing solutions often center on hosted memory layers, API keys, or opaque context pipelines. What you actually need is to resume the next session with the minimum correct context and a trail you can inspect.

rememb is built around four memory problems:

• durable facts and decisions instead of session-only chat memory
• keyword search instead of rereading everything (agents judge relevance)
• non-destructive versioning instead of silent overwrites
• local-first audit trail for AI work, not opaque cloud logs

Install

pip install rememb

Quick Start

With MCP (recommended)

Zero friction. No CLI commands. Native IDE integration.

1. Add to your IDE's MCP config:

{
  "mcpServers": {
    "rememb": {
      "command": "rememb",
      "args": ["mcp"]
    }
  }
}

2. Restart your IDE.

The agent can read stored context at session start, write durable memory when something changes, and search only when targeted recall is needed.

If you want rememb usage to stay consistent, add a rememb-specific instruction block in your IDE custom instructions or in the MCP client prompt that wraps the agent. The point is to make the agent route reads, writes, search, recovery, and maintenance through rememb instead of ad hoc prompt memory.

You can place that block in either of these places:

• IDE-level custom instructions
• the system prompt or instruction field of the MCP client that is calling rememb

In both cases, keep the scope explicit: these rules are about how the agent should use rememb, not about replacing the rest of your coding instructions.

For the exact copy-paste block, use the canonical rules section in MCP_TOOLS.md.

No extra storage setup, server config, or schema migration is required. In MCP mode, rememb resolves storage home-first and auto-initializes ~/.rememb when needed.

For the current public MCP tool list (17 tools) and descriptions, see MCP_TOOLS.md.

If you want multiple MCP clients on the same machine to reuse one already-running rememb process, start a persistent local SSE transport:

rememb mcp --transport sse --host 127.0.0.1 --port 8765

This keeps one MCP process alive, so repeated clients can connect through http://127.0.0.1:8765/sse and http://127.0.0.1:8765/messages/.

Do not put --transport sse inside a stdio MCP client config. stdio clients expect JSON-RPC on stdin/stdout; the SSE mode exposes an HTTP endpoint and must be started separately.
