Integrations
Connect Claude Code with your development tools and workflows
title: Integrations description: Connect Claude Code with your development tools and workflows
Claude Code integrates seamlessly with your existing development environment. This section covers MCP servers, IDE plugins, hooks, and other ways to extend Claude Code's capabilities.
Overview
Claude Code can be extended through several mechanisms:
| Integration Type | Purpose | Complexity | |------------------|---------|------------| | MCP Servers | Add new capabilities and data sources | Medium | | IDE Plugins | Native IDE integration | Low | | Hooks | Custom automation and workflows | Medium | | API | Programmatic access | High |
MCP (Model Context Protocol)
MCP servers extend Claude's capabilities by providing:
- Data sources - Access databases, APIs, file systems
- Tools - New actions Claude can perform
- Context - Additional information for better responses
Quick Example
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@anthropic-ai/mcp-server-filesystem", "/path/to/allowed/dir"]
}
}
}
IDE Plugins
Native integration with popular IDEs:
- VS Code - Full-featured extension
- JetBrains - IntelliJ, WebStorm, PyCharm, etc.
- Neovim - Terminal-based integration
Benefits
- Inline code suggestions
- Context-aware completions
- Seamless workflow integration
- No terminal switching required
Hooks
Hooks let you run custom commands at specific points in Claude Code's lifecycle:
- Pre-tool hooks - Run before Claude executes a tool
- Post-tool hooks - Run after tool execution
- Notification hooks - Alert on specific events
Quick Example
{
"hooks": {
"preToolExecution": [
{
"matcher": "Write",
"command": "echo 'About to write to: $FILE_PATH'"
}
]
}
}
Common Integration Patterns
1. Database Access
Connect Claude to your databases for query assistance:
{
"mcpServers": {
"postgres": {
"command": "npx",
"args": ["-y", "@anthropic-ai/mcp-server-postgres"],
"env": {
"POSTGRES_URL": "postgresql://localhost/mydb"
}
}
}
}
2. Git Integration
Enhance git workflows with automation:
{
"hooks": {
"postToolExecution": [
{
"matcher": "Bash:git commit",
"command": "git log -1 --oneline"
}
]
}
}
3. CI/CD Integration
Trigger builds and tests automatically:
{
"hooks": {
"postToolExecution": [
{
"matcher": "Write:*.ts",
"command": "npm run typecheck"
}
]
}
}
4. Documentation Generation
Auto-generate docs when code changes:
{
"hooks": {
"postToolExecution": [
{
"matcher": "Write:src/**/*.ts",
"command": "npm run docs:generate"
}
]
}
}
Security Considerations
When setting up integrations:
- Principle of least privilege - Only grant necessary permissions
- Environment isolation - Use separate configs for dev/prod
- Secret management - Never commit API keys or passwords
- Audit logging - Track what integrations are doing
Secure Configuration
{
"mcpServers": {
"database": {
"command": "npx",
"args": ["-y", "@anthropic-ai/mcp-server-postgres"],
"env": {
"POSTGRES_URL": "${POSTGRES_URL}"
}
}
}
}
Use environment variables instead of hardcoding secrets.
Troubleshooting
MCP Server Not Starting
- Check the command is installed:
npx -y @anthropic-ai/mcp-server-xxx --version - Verify permissions for file paths
- Check logs:
claude --mcp-debug
Hook Not Executing
- Verify matcher pattern matches the tool
- Check command exists and is executable
- Test command manually in terminal
IDE Plugin Not Connecting
- Ensure Claude Code CLI is installed globally
- Check extension settings for correct path
- Restart IDE after installation
