# Workplan: Claude Code Web Support via Project Hooks
## Overview
Enable MemoryGraph to work seamlessly in Claude Code Web (remote) environments using project hooks for automatic installation and configuration.
## Goals
1. Auto-install MemoryGraph in remote environments via SessionStart hook
2. Support conditional cloud backend when `MEMORYGRAPH_API_KEY` is present
3. Provide copy-paste hook files for users to add to their projects
4. Document setup for both local and remote usage
---
## Prerequisites
- [ ] memorygraph.dev implementation with API endpoints and API key generation
---
## Success Criteria
- [ ] MemoryGraph installs automatically when Claude Code Web session starts
- [ ] Local CLI users are unaffected (hook exits early)
- [ ] Cloud backend activates when env vars are present
- [ ] Users can copy example hooks into their projects
- [ ] Documentation covers all scenarios
---
## Phase 1: Hook Scripts
### Task 1.1: Create Installation Hook Script
**File:** `examples/claude-code-hooks/install-memorygraph.sh`
```bash
#!/bin/bash
set -e
# ============================================================
# MemoryGraph Auto-Installation Hook for Claude Code
#
# This script runs on SessionStart in Claude Code environments.
# - Remote (web): Installs MemoryGraph automatically
# - Local (CLI): Exits early (user manages installation)
# ============================================================
# Skip installation in local environments
if [ "$CLAUDE_CODE_REMOTE" != "true" ]; then
echo "[memorygraph] Local environment - skipping auto-install"
exit 0
fi
echo "[memorygraph] Remote environment detected"
# Check if already installed
if python -c "import memorygraph" 2>/dev/null; then
echo "[memorygraph] Already installed"
else
echo "[memorygraph] Installing memorygraphMCP..."
pip install --quiet memorygraphMCP
fi
# Add MCP server if not already configured
if ! claude mcp list 2>/dev/null | grep -q "memorygraph"; then
echo "[memorygraph] Adding MCP server..."
claude mcp add memorygraph
fi
# Configure cloud backend if API key is present
if [ -n "$MEMORYGRAPH_API_KEY" ]; then
echo "[memorygraph] Cloud backend configured"
if [ -n "$CLAUDE_ENV_FILE" ]; then
echo "MEMORYGRAPH_API_KEY=$MEMORYGRAPH_API_KEY" >> "$CLAUDE_ENV_FILE"
[ -n "$MEMORYGRAPH_API_URL" ] && echo "MEMORYGRAPH_API_URL=$MEMORYGRAPH_API_URL" >> "$CLAUDE_ENV_FILE"
fi
else
echo "[memorygraph] Using local SQLite (ephemeral in remote environments)"
echo "[memorygraph] Set MEMORYGRAPH_API_KEY for persistent cloud storage"
fi
echo "[memorygraph] Ready"
exit 0
```
**Checklist:**
- [x] Create `examples/claude-code-hooks/` directory
- [x] Create `install-memorygraph.sh` with above content
- [x] Make script executable (`chmod +x`)
- [x] Test script locally with `CLAUDE_CODE_REMOTE=true`
- [x] Test script locally without env var (should exit early)
### Task 1.2: Create Hook Configuration File
**File:** `examples/claude-code-hooks/settings.json`
```json
{
"hooks": {
"SessionStart": [
{
"hooks": [
{
"type": "command",
"command": "$CLAUDE_PROJECT_DIR/.claude/hooks/install-memorygraph.sh"
}
]
}
]
}
}
```
**Checklist:**
- [x] Create `settings.json` in `examples/claude-code-hooks/`
- [x] Validate JSON syntax
- [x] Test hook registration with Claude Code locally
### Task 1.3: Create Minimal Hook Variant
**File:** `examples/claude-code-hooks/install-memorygraph-minimal.sh`
A simpler version without cloud backend support:
```bash
#!/bin/bash
# Minimal MemoryGraph installation for Claude Code Web
[ "$CLAUDE_CODE_REMOTE" != "true" ] && exit 0
pip install --quiet memorygraphMCP
claude mcp add memorygraph 2>/dev/null || true
echo "[memorygraph] Ready"
```
**Checklist:**
- [x] Create minimal variant script
- [x] Make executable
- [x] Test in isolation
---
## Phase 2: Cloud Backend Detection
### Task 2.1: Update MCP Server to Detect Cloud Mode
**File:** `src/memorygraph/server.py` (or equivalent entry point)
Add environment variable detection at startup:
```python
import os
def get_backend_config():
"""Determine backend configuration from environment."""
api_key = os.environ.get("MEMORYGRAPH_API_KEY")
api_url = os.environ.get("MEMORYGRAPH_API_URL", "https://api.memorygraph.dev")
if api_key:
return {
"mode": "cloud",
"api_key": api_key,
"api_url": api_url
}
# Check for Turso (alternative cloud backend)
turso_url = os.environ.get("MEMORYGRAPH_TURSO_URL")
turso_token = os.environ.get("MEMORYGRAPH_TURSO_TOKEN")
if turso_url and turso_token:
return {
"mode": "turso",
"url": turso_url,
"token": turso_token
}
# Default to local SQLite
db_path = os.environ.get("MEMORYGRAPH_DB_PATH", "~/.memorygraph/memory.db")
return {
"mode": "local",
"db_path": os.path.expanduser(db_path)
}
```
**Checklist:**
- [x] Add `get_backend_config()` function
- [x] Integrate config detection into server initialization
- [x] Log which backend mode is active on startup
- [x] Handle missing cloud backend gracefully (fall back to local)
- [x] Add unit tests for config detection
### Task 2.2: Add Cloud Backend Stub (Placeholder)
**File:** `src/memorygraph/backends/cloud.py`
```python
"""
Cloud backend for MemoryGraph.
This is a placeholder for future cloud sync functionality.
When MEMORYGRAPH_API_KEY is set, this backend will sync
memories to the MemoryGraph cloud service.
"""
class CloudBackend:
"""Placeholder for cloud backend implementation."""
def __init__(self, api_key: str, api_url: str):
self.api_key = api_key
self.api_url = api_url
# TODO: Implement in Phase 3 (Cloud Sync)
raise NotImplementedError(
"Cloud backend coming soon. "
"For now, use local SQLite or Turso for persistent storage."
)
```
**Checklist:**
- [x] Create `backends/cloud.py` with placeholder
- [x] Add clear error message directing users to alternatives
- [x] Document in code when this will be implemented
### Task 2.3: Add Turso Backend Support (Optional)
**File:** `src/memorygraph/backends/turso.py`
If not already implemented, add Turso support for users who want cloud persistence today:
```python
"""
Turso (libSQL) backend for MemoryGraph.
Provides cloud-hosted SQLite-compatible storage.
Users can create a free Turso database and use it
for persistent memory in Claude Code Web.
"""
import libsql_experimental as libsql
class TursoBackend:
"""Turso/libSQL backend using same schema as SQLite."""
def __init__(self, url: str, token: str):
self.conn = libsql.connect(url, auth_token=token)
self._init_schema()
def _init_schema(self):
"""Initialize database schema (same as SQLite backend)."""
# Reuse existing SQLite schema
pass
```
**Checklist:**
- [x] Check if Turso backend already exists
- [x] If not, create `backends/turso.py`
- [x] Reuse SQLite schema for compatibility
- [x] Add `libsql-experimental` to optional dependencies
- [x] Test with Turso free tier database
- [x] Document Turso setup in README
---
## Phase 3: Example Project Structure
### Task 3.1: Create Complete Example Directory
**Directory:** `examples/claude-code-hooks/`
```
examples/claude-code-hooks/
├── README.md # Setup instructions
├── .claude/
│ ├── settings.json # Hook configuration
│ └── hooks/
│ └── install-memorygraph.sh # Installation script
└── copy-to-project.sh # Helper script to copy files
```
**Checklist:**
- [x] Create directory structure
- [x] Create all files listed above
- [x] Add `copy-to-project.sh` helper script
- [x] Test copying to a fresh project directory
### Task 3.2: Create Example README
**File:** `examples/claude-code-hooks/README.md`
```markdown
# MemoryGraph Hooks for Claude Code Web
This directory contains hook files to auto-install MemoryGraph
in Claude Code Web (remote) environments.
## Quick Setup
Copy the `.claude` directory to your project root:
\`\`\`bash
cp -r examples/claude-code-hooks/.claude /path/to/your/project/
\`\`\`
Or use the helper script:
\`\`\`bash
./examples/claude-code-hooks/copy-to-project.sh /path/to/your/project
\`\`\`
## How It Works
1. When Claude Code Web starts, it runs SessionStart hooks
2. The hook detects it's in a remote environment (`CLAUDE_CODE_REMOTE=true`)
3. MemoryGraph is installed via pip and added as an MCP server
4. Your AI assistant now has memory!
## Cloud Persistence (Optional)
By default, memories in remote environments are ephemeral (lost when session ends).
For persistent storage, add these environment variables in Claude Code Web settings:
\`\`\`env
MEMORYGRAPH_API_KEY=your-api-key # Get from memorygraph.dev (coming soon)
\`\`\`
Or use your own Turso database:
\`\`\`env
MEMORYGRAPH_TURSO_URL=libsql://your-db.turso.io
MEMORYGRAPH_TURSO_TOKEN=your-token
\`\`\`
## Local vs Remote Behavior
| Environment | Behavior |
|-------------|----------|
| Local CLI | Hook exits early. Install manually with `pip install memorygraphMCP` |
| Remote (no cloud key) | Auto-installs. Ephemeral SQLite storage. |
| Remote (with cloud key) | Auto-installs. Persistent cloud storage. |
## Files
- `.claude/settings.json` - Hook configuration
- `.claude/hooks/install-memorygraph.sh` - Installation script
## Troubleshooting
**Hook not running:**
- Ensure `.claude/` is in your project root (not a subdirectory)
- Check that `install-memorygraph.sh` is executable
**MCP server not available:**
- Restart Claude Code after hook runs
- Check hook output in session logs
**Memories not persisting:**
- Set `MEMORYGRAPH_API_KEY` or `MEMORYGRAPH_TURSO_URL` for persistence
- Without cloud config, remote memories are lost on session end
```
**Checklist:**
- [x] Create README.md with above content
- [x] Review for accuracy
- [x] Add troubleshooting section
- [x] Include links to main documentation
### Task 3.3: Create Copy Helper Script
**File:** `examples/claude-code-hooks/copy-to-project.sh`
```bash
#!/bin/bash
set -e
TARGET_DIR="${1:-.}"
if [ ! -d "$TARGET_DIR" ]; then
echo "Error: Directory '$TARGET_DIR' does not exist"
exit 1
fi
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
echo "Copying MemoryGraph hooks to $TARGET_DIR..."
# Create .claude directory if needed
mkdir -p "$TARGET_DIR/.claude/hooks"
# Copy files
cp "$SCRIPT_DIR/.claude/settings.json" "$TARGET_DIR/.claude/"
cp "$SCRIPT_DIR/.claude/hooks/install-memorygraph.sh" "$TARGET_DIR/.claude/hooks/"
# Make hook executable
chmod +x "$TARGET_DIR/.claude/hooks/install-memorygraph.sh"
echo "Done! MemoryGraph hooks installed."
echo ""
echo "Next steps:"
echo " 1. Commit .claude/ to your repository"
echo " 2. Open project in Claude Code Web"
echo " 3. MemoryGraph will auto-install on session start"
```
**Checklist:**
- [x] Create copy helper script
- [x] Make executable
- [x] Test on fresh directory
- [x] Handle edge cases (existing .claude dir, etc.)
---
## Phase 4: Documentation Updates
### Task 4.1: Update Main README
**File:** `README.md`
Add new section:
```markdown
## Claude Code Web Support
MemoryGraph works in Claude Code Web (remote) environments via project hooks.
### Quick Setup
Copy the hook files to your project:
\`\`\`bash
# From memorygraph repo
cp -r examples/claude-code-hooks/.claude /path/to/your/project/
# Commit to your repo
cd /path/to/your/project
git add .claude/
git commit -m "Add MemoryGraph auto-install hooks"
\`\`\`
When you open this project in Claude Code Web, MemoryGraph installs automatically.
### Persistent Storage (Optional)
Remote environments are ephemeral. For persistent memories, configure cloud storage
in your Claude Code Web environment variables:
| Variable | Description |
|----------|-------------|
| `MEMORYGRAPH_API_KEY` | API key from memorygraph.dev (coming soon) |
| `MEMORYGRAPH_TURSO_URL` | Your Turso database URL |
| `MEMORYGRAPH_TURSO_TOKEN` | Your Turso auth token |
See [Claude Code Web Setup](docs/claude-code-web.md) for detailed instructions.
```
**Checklist:**
- [x] Add "Claude Code Web Support" section to README
- [x] Keep it concise with link to full docs
- [x] Include quick copy-paste commands
- [x] Mention persistence options
### Task 4.2: Create Dedicated Documentation Page
**File:** `docs/claude-code-web.md`
```markdown
# Using MemoryGraph with Claude Code Web
Claude Code Web runs in ephemeral cloud containers. This guide explains
how to use MemoryGraph in these environments.
## How It Works
Claude Code supports [project hooks](https://code.claude.com/docs/en/hooks)
that run on session start. MemoryGraph provides hook files that:
1. Detect remote environment via `CLAUDE_CODE_REMOTE` env var
2. Install MemoryGraph via pip
3. Register the MCP server
4. Configure cloud backend if API key is present
## Installation
### Option 1: Copy Hook Files (Recommended)
Copy the provided hooks to your project:
\`\`\`bash
# Clone or download memorygraph
git clone https://github.com/gregorydickson/memory-graph.git
# Copy hooks to your project
cp -r memory-graph/examples/claude-code-hooks/.claude /path/to/your/project/
# Commit to version control
cd /path/to/your/project
git add .claude/
git commit -m "Add MemoryGraph hooks for Claude Code Web"
git push
\`\`\`
### Option 2: Manual Setup
Create these files in your project:
**`.claude/settings.json`:**
\`\`\`json
{
"hooks": {
"SessionStart": [
{
"hooks": [
{
"type": "command",
"command": "$CLAUDE_PROJECT_DIR/.claude/hooks/install-memorygraph.sh"
}
]
}
]
}
}
\`\`\`
**`.claude/hooks/install-memorygraph.sh`:**
\`\`\`bash
#!/bin/bash
[ "$CLAUDE_CODE_REMOTE" != "true" ] && exit 0
pip install --quiet memorygraphMCP
claude mcp add memorygraph 2>/dev/null || true
echo "[memorygraph] Ready"
\`\`\`
Make the script executable:
\`\`\`bash
chmod +x .claude/hooks/install-memorygraph.sh
\`\`\`
## Persistent Storage
By default, memories in Claude Code Web are **ephemeral**—they're lost when
the session ends. For persistent storage, configure a cloud backend.
### Option A: MemoryGraph Cloud (Coming Soon)
1. Sign up at [memorygraph.dev](https://memorygraph.dev)
2. Get your API key
3. Add to Claude Code Web environment variables:
- `MEMORYGRAPH_API_KEY`: Your API key
### Option B: Bring Your Own Turso Database
[Turso](https://turso.tech) offers free SQLite-compatible cloud databases.
1. Create a Turso account and database
2. Get your database URL and auth token
3. Add to Claude Code Web environment variables:
- `MEMORYGRAPH_TURSO_URL`: `libsql://your-db-name.turso.io`
- `MEMORYGRAPH_TURSO_TOKEN`: Your auth token
### Setting Environment Variables
In Claude Code Web:
1. Click the environment dropdown (shows "Default")
2. Click "New cloud environment" or edit existing
3. Add variables in the "Environment variables" section
4. Click "Create environment" or "Save"
## Behavior Summary
| Environment | Detection | Storage | Persistence |
|-------------|-----------|---------|-------------|
| Local CLI | `CLAUDE_CODE_REMOTE` not set | Local SQLite | ✅ Persistent |
| Remote (no config) | `CLAUDE_CODE_REMOTE=true` | Local SQLite | ❌ Ephemeral |
| Remote + API key | `CLAUDE_CODE_REMOTE=true` | Cloud API | ✅ Persistent |
| Remote + Turso | `CLAUDE_CODE_REMOTE=true` | Turso DB | ✅ Persistent |
## Troubleshooting
### Hook not executing
- Verify `.claude/settings.json` is valid JSON
- Check that `.claude/hooks/install-memorygraph.sh` is executable
- Ensure files are committed and pushed to your repository
### MCP server not available after install
- The MCP server registers after the hook runs
- Try sending a message to trigger Claude to reload tools
- Check session logs for hook output
### Memories not persisting between sessions
- This is expected without cloud configuration
- Set `MEMORYGRAPH_API_KEY` or Turso credentials for persistence
- Verify environment variables are set in the correct cloud environment
### Permission denied errors
- Ensure the hook script has execute permissions: `chmod +x .claude/hooks/install-memorygraph.sh`
- Commit the executable bit: `git update-index --chmod=+x .claude/hooks/install-memorygraph.sh`
## Local Development
The hooks are designed to be safe for local use:
- On local CLI, hooks exit immediately (no-op)
- Local installation uses the normal flow: `pip install memorygraphMCP && claude mcp add memorygraph`
- You can test hooks locally by setting `CLAUDE_CODE_REMOTE=true`
## Security Considerations
- Hook scripts run with the same permissions as Claude Code
- The installation script only installs from PyPI (trusted source)
- Cloud credentials are stored in Claude Code's secure environment variable storage
- No credentials are logged or exposed in hook output
```
**Checklist:**
- [x] Create `docs/claude-code-web.md`
- [x] Include all installation options
- [x] Document environment variables
- [x] Add troubleshooting section
- [x] Include security considerations

## Notes for Coding Agent
1. **File paths are relative to repository root** unless otherwise specified
2. **Test each phase before moving to next** - hooks must work before documentation
3. **Keep scripts POSIX-compliant** - avoid bash-specific features where possible
4. **Error handling is critical** - hooks should fail gracefully, not break sessions
5. **Check existing code** before creating new files - some backends may already exist
6. **Run `chmod +x`** on all shell scripts before committing
## Dependencies
- No new Python dependencies for basic hook support
- Optional: `libsql-experimental` for Turso backend
- Optional: `httpx` for future cloud API client
## Estimated Effort
| Phase | Effort |
|-------|--------|
| Phase 1: Hook Scripts | 1-2 hours |
| Phase 2: Cloud Backend Detection | 2-3 hours |
| Phase 3: Example Project Structure | 1 hour |
| Phase 4: Documentation | 2-3 hours |
| Phase 5: Testing | 1-2 hours |
| **Total** | **7-11 hours** |
