Memocall MCP server

MemoCall

An MCP server that lets Claude Code recall the context of your past conversations — from any project — on demand.

Claude Code can resume a session, but getting another conversation's context into the one you're in is a chore — copy-pasting exports or digging through raw transcript files by hand — and resume only sees the current directory anyway. MemoCall turns it into a single ask: "what was I working on?" or "load the session where we set up X", and it pulls that transcript in as clean, compact Markdown — even from a totally different project.

It's read-only. Claude Code already records every session to ~/.claude/projects//.jsonl; this server just reads those files, strips the noise, collapses tool calls, and hands back a readable transcript. It never writes, hooks, or touches a live session.

What you get

Five tools, available in every session once installed. Claude picks the right one from the request:

You don't call these directly — you talk normally and Claude reaches for them:

You:  what sessions have i worked on recently?
You:  load the one where we set up the license invitation system
You:  which session did we debug the keychain SIGKILL thing in?

How the transcript is rendered

Raw transcripts are a verbose event log (one big file hit 11 MB). memocall reduces each turn to the essentials, Conductor-style:

**You:** right now i need to set up a system to invite prospects...
↳ 12 tool calls (Bash ×5, Read ×4, Edit ×3)
**Claude:** I've set up the invitation flow. Key decisions: ...

Tool-call outputs are elided (the big token win, and a privacy win — see below). Abandoned/edited message branches are dropped so you get the conversation as it actually played out. A token budget keeps even an 11 MB session well under Claude Code's MCP output cap via middle-out truncation.

Navigating large sessions

A single response can't hold a 1,000-turn session, so for big ones you don't dump — you navigate:

1. session_outline → a numbered map of every prompt (tiny, fits any session).
2. searchinsession → jump straight to the turns about a topic, or load_session with turns: "300-340" to pull an exact window (turn numbers come from the outline).

So you never lose access to the middle of a huge conversation — load_session alone would middle-out-truncate it, but the outline + range/search tools let Claude reach any part on demand.

Install

Requires the Claude Code CLI (and Node 18+). One line — npx fetches and runs the published package:

claude mcp add --scope user memocall -- npx -y memocall

--scope user makes it available in every session, in every directory. Restart Claude Code (or open a new session) and ask it to list your sessions. Verify with claude mcp list — you should see memocall: … ✔ Connected.

Or run from source (for development)

git clone https://github.com/baodq06/memocall.git
cd memocall && npm install && npm run build
claude mcp add --scope user memocall -- node "$(pwd)/dist/index.js"
