Threadmap Mcp

🗺️ ThreadMap MCP for Claude

Conversation drift visualization and forking for Claude.

Stop losing your original intent. See exactly where your conversation drifted. Fork from any point and pick up with clean context.

See it in action

Color dots on every message — live drift tracking:

Timeline panel with fork buttons at every inflection point:

Two ways to use ThreadMap

Both are in this repo. Use one or both.

Chrome Extension — Visual dots in claude.ai

The Chrome extension injects ThreadMap directly into the claude.ai interface. No config. Just install and open Claude.

Install (2 minutes)

1. Clone or download this repo2. Open Chrome → chrome://extensions3. Enable Developer mode (top right toggle)4. Click Load unpacked → select the chrome-extension folder5. Open any Claude conversation — ThreadMap activates automatically

What you see

• Color dot next to every message showing drift % from your original intent
• Sticky bar at the top with live drift status and message count
• ↺ rescan — loads all messages from long previous conversations
• timeline — full conversation map, click any row to jump to that message
• ⑂ fork — opens a new Claude chat with full context pre-loaded in the input

How forking works

1. Click ⑂ fork in the timeline or next to any message bubble
2. A new claude.ai tab opens automatically
3. The full context (origin intent + all messages up to that point) is pasted into the input
4. Review and hit Send — Claude picks up from the clean version

Chrome extension files

Heads up: The extension uses Developer mode (load unpacked). A Chrome Web Store version is on the roadmap.

MCP Server — Claude Code integration

The MCP server adds 7 tools to Claude Code for programmatic drift tracking.

Install

claude mcp add threadmap npx threadmap-mcp

Or manually add to ~/.claude/claude_desktop_config.json:

{  "mcpServers": {    "threadmap": {      "command": "npx",      "args": ["threadmap-mcp"]    }  }}

Quick start

threadmap_track(sessionId="myproject", role="user", content="build me a login system with JWT auth")→ 🔵 Blue — Drift: 0% — Origin intent set
threadmap_track(sessionId="myproject", role="user", content="the refresh token keeps expiring after 30 seconds")→ 🟠 Orange — Drift: 63% — ⚡ INFLECTION POINT detected
threadmap_timeline(sessionId="myproject")→ Full color-coded map of all messages with fork instructions
threadmap_fork(sessionId="myproject", messageIndex=6, branchName="jwt-debug")→ 🌿 Branch created — clean context from messages 1–7

All 7 tools

Color system

Orange and Red = fork candidates. The conversation has left your original intent behind.

Real-world use cases

Claude Code — architecture integrity Track every message while building. Orange = scope creep. Fork before the drift gets worse. Architecture decisions from the first 10 messages stay clean.

Long previous conversations Click ↺ rescan in the Chrome extension. ThreadMap scrolls to the top, loads all messages, scans every one, then returns you to the bottom — all dots appear.

Team handoffs Use threadmap_branch_context to extract a clean summary of what was decided. Paste it into a new session — no scrolling through 200 messages.

Why open source?

Non-linear conversation navigation is the missing primitive for AI-native work. Right now Claude conversations are books with no table of contents, no chapters, no bookmarks.

ThreadMap is the table of contents. If this becomes the standard, it travels across Claude, GPT, Gemini, anything. Nobody owns it. Everybody benefits.

Roadmap

• Local embedding model (MiniLM) for richer semantic scoring
• Chrome extension on Chrome Web Store (no developer mode required)
• Cross-session persistence (SQLite mode)
• Visual timeline export (SVG/HTML)
• GPT / Gemini compatibility
