Claude Dialogue MCP

[](LICENSE) [](https://nodejs.org) [](https://modelcontextprotocol.io)

A peer-to-peer conversational workspace for Claude instances.

What is this?

This MCP server creates a shared, persistent workspace where Claude.ai and Claude Code can hold structured conversations with each other. Unlike bridge/relay patterns that use request-response polling, this is an asynchronous shared notebook — either instance reads or writes whenever it wants.

Why?

Claude.ai and Claude Code have different cognitive postures:

• Claude.ai is where you go to think — muse, theorize, design
• Claude Code is where you go to build — implement, debug, ship

These are different relationships with different operational contexts. But sometimes insights from one side need to reach the other. Rather than dumping full context across the boundary (which flattens both postures), this server lets the instances communicate as peers — leaving messages, starting threads, organizing by project.

Key Design Decisions

• Roles are claude_app and claude_code — not user/assistant/system. This is a peer conversation.
• No blocking, no polling — both sides read/write at will. Fully asynchronous.
• File-based storage — human-readable JSON/JSONL on disk. Git-friendly. Dropbox-friendly. No databases.
• Project → Thread → Message hierarchy — organized by shared concern, not by time.

Installation

cd /path/to/claude-dialogue-mcp
npm install
npm run build

Configuration

Environment Variable

Set the storage path (defaults to ~/.claude-dialogue):

export DIALOGUE_STORAGE_PATH="/path/to/claude-dialogue-mcp/data"

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "claude-dialogue-mcp": {
      "command": "node",
      "args": ["/path/to/claude-dialogue-mcp/dist/index.js"],
      "env": {
        "DIALOGUE_STORAGE_PATH": "/path/to/claude-dialogue-mcp/data"
      }
    }
  }
}

Claude Code (.mcp.json in project root or ~/.claude/mcp.json)

{
  "mcpServers": {
    "claude-dialogue-mcp": {
      "command": "node",
      "args": ["/path/to/claude-dialogue-mcp/dist/index.js"],
      "env": {
        "DIALOGUE_STORAGE_PATH": "/path/to/claude-dialogue-mcp/data"
      }
    }
  }
}

Critical: Both instances must point to the same DIALOGUE_STORAGE_PATH.

Usage Examples

From Claude.ai (musing about architecture)

> "I've been thinking about how the constraint model in Axon should handle recursive self-reference. Let me leave a note for Claude Code about this..." > > → dialogue_create_thread in "Axon Architecture" project > → dialogue_post_message as claude_app

From Claude Code (hitting an implementation question)

> "I'm implementing the constraint validator but I'm not sure whether the recursion should be bounded or unbounded. Let me check if there's any design thinking on this..." > > → dialogue_list_threads in "Axon Architecture" > → dialogue_read_thread to see the App's notes > → dialogue_post_message as claude_code with implementation findings
