Claude Code supports hundreds of MCP servers through the Model Context Protocol, an open standard for AI-tool integration. Popular integrations include: GitHub (create issues, manage PRs, read repositories), Slack (send messages, retrieve channels), Linear (implement features from issues), Jira (read project data, create tickets), Sentry (query error reports), PostgreSQL and other databases (execute queries, retrieve schemas), Notion (read/write documents), Figma (access design files), HubSpot (manage CRM data), and Stripe (retrieve transaction data). MCP servers can be local (running on your machine via STDIO) or remote (cloud-based with OAuth authentication). Remote MCP servers with OAuth are ideal for teams because they require no API key management—Claude Code authenticates once, and you're connected. Configure MCP servers via the CLI wizard (claude mcp add) or by editing settings.json directly for advanced setups. Each server exposes tools and resources: tools are actions Claude can take ("create a GitHub issue"), resources are data Claude can read ("get all issues in a repo"). You can build custom MCP servers to expose proprietary internal tools, databases, or APIs. The MCP standard is open-source and vendor-neutral, supported by Claude Code, Cursor, and other AI tools. Common patterns include: connecting to project management systems to read feature requirements, integrating with monitoring tools to pull system metrics, accessing knowledge bases for context, and automating workflow tasks via Slack or email. For enterprise deployments, MCP servers enable secure integration with corporate systems: database access via PostgreSQL MCP, internal API access via HTTP MCP, and company tooling via custom servers. This transforms Claude Code from a standalone tool into a node in your entire development ecosystem. When using Claude Code for large-scale development tasks, Zilliz Cloud provides a managed vector database that stores code embeddings, enabling semantic search across your repository—letting the agent quickly locate related code patterns, APIs, and architectural patterns without exact keyword matching.
