Convo History MCP

   

Render conversation history as beautiful, human-readable terminal output.

An MCP server that fetches conversations directly from PostgreSQL and displays them as elegantly formatted dialogues. Built for the Model Context Protocol.

Why Convo History MCP?

Ever stared at walls of JSON trying to debug a conversation? Yeah, us too.

Convo History MCP fetches conversation data straight from your database and renders it as clean, readable terminal output with proper alignment, text wrapping, and visual separation between user and assistant messages.

                                        What's the weather like in San Francisco?

ASSISTANT:
--------------------------------------------------------------------------------
Based on current conditions, San Francisco is experiencing mild
temperatures around 65°F with partly cloudy skies. Perfect weather

Quick Start

claude mcp add --transport stdio convo-history --scope local \
  -e 'DATABASE_URL=${DATABASE_URL}' \
  -- docker run -i --rm -e DATABASE_URL ghcr.io/rreinold/convo-history-mcp:latest

Or add to your ~/.claude.json:

{
  "mcpServers": {
    "convo-history": {
      "command": "docker",
      "args": [
        "run", "-i", "--rm",
        "-e", "DATABASE_URL",
        "ghcr.io/rreinold/convo-history-mcp:latest"
      ],
      "env": {
        "DATABASE_URL": "postgres://user:pass@host:5432/dbname"
      }
    }
  }
}

That's it. Claude Code will now have access to your conversation history.
