AI Sessions MCP Server

An MCP server that makes sessions from Claude Code, OpenAI Codex, Gemini CLI and opencode available to any MCP compatible client.

Mostly written using Claude Code.

What It Does

Allow AI agents to search, list, and read your previous local coding sessions from multiple CLI coding agents. Useful for:

• Finding past solutions to similar problems
• Reviewing what you worked on recently
• Learning from previous conversations
• Resuming interrupted work

Demo

Installation

Download Pre-built Binary

Download the latest release for your platform from GitHub Releases. Unzip and move the binary somewhere in your path and point your MCP config at that location.

Build from Source

Prerequisites: Go 1.25 or later

cd ai-sessions-mcp
go build -o bin/ai-sessions-mcp ./cmd/ai-sessions-mcp

Move the resulting binary anywhere you like and use that path in your MCP config.

Setup

Claude Code

claude mcp add ai-sessions /path/to/ai-sessions-mcp

Codex CLI

Edit ~/.codex/config.toml and add:

[mcp_servers.ai_session]
command = "/path/to/ai-sessions-mcp"

Claude Desktop

Add to your Claude Desktop config file (open via Settings -> Developer -> Edit Config)

{
  "mcpServers": {
    "ai-sessions": {
      "command": "/path/to/ai-sessions-mcp"
    }
  }
}

Restart Claude Desktop to activate.

Usage

Once configured, you can ask:

• "Let's continue my latest sesion from Claude Code"
• "Show me my recent Codex sessions"
• "Search my sessions for authentication bugs"
• "How many times did Claude tell me I was absolutely right yesterday?"

How It Works

The server reads session files stored locally by various CLI coding agents:

• Claude Code: ~/.claude/projects/[PROJECT_DIR]/*.jsonl
• Gemini CLI: ~/.gemini/tmp/[PROJECT_HASH]/chats/session-*.json
• OpenAI Codex: ~/.codex/sessions/ and ~/.codex/archived_sessions/
• opencode: ~/.local/share/opencode/storage/

When you ask your AI agent to list or search sessions, it automatically uses these agents to access your session history.

Available Tools

list_available_sources

Shows which AI CLI coding agents have sessions on your system.

list_sessions

Lists recent sessions from all projects (newest first).

Arguments:

• source (optional): Filter by claude, gemini, codex, or opencode
• project_path (optional): Filter by specific project directory
• limit (optional): Max results (default: 10)

Example: {"source": "claude", "limit": 20}

search_sessions

Searches session content using BM25 ranking. Returns results sorted by relevance score with contextual snippets.

Arguments:

• query (required): Search term (supports multiple keywords)
• source (optional): Filter by source
• project_path (optional): Filter by project
• limit (optional): Max results (default: 10)

Example: {"query": "authentication bug"}

Returns: Each match includes:

• session: Session metadata (ID, source, project, timestamp)
• score: Relevance score (higher = more relevant)
• snippet: Contextual excerpt (~300 chars) showing where the match occurred

get_session

Retrieves full session content with pagination.

Arguments:

• session_id (required): Session ID from list results
• source (required): Which coding agent created it
• page (optional): Page number (default: 0)
• page_size (optional): Messages per page (default: 20)
