Configure MCP servers on Cursor SDK agents โ stdio subprocess, HTTP, and SSE transports, inline vs file-based config, and per-run overrides. Use when extending an agent's tools beyond the built-ins.
Install with Codex or Claude Copy this prompt, paste it into Codex, Claude, or another assistant, and let it review the skill page and install it for you.
Based on SOC occupation classification
The `agent` CLI โ install, interactive modes (Agent / Plan / Ask), headless `-p` mode for CI, GitHub Actions integration, and how it relates to the TypeScript SDK. Use when scripting Cursor in shell pipelines or workflows instead of (or alongside) the SDK.
Cloud runtime for Cursor SDK โ dedicated VMs, repo-bound runs, auto-PR creation, artifacts, and reattachment. Use when running long, review-oriented, or repo-modifying agents off the local machine.
CursorAgentError class hierarchy, isRetryable, and recovery patterns. Use when classifying SDK failures, building retry logic, or surfacing actionable messages.
File-based agent loop hooks via `.cursor/hooks.json` โ pre/post commands, governance gates. Use when enforcing policy without modifying agent prompts.
Model discovery and selection on Cursor SDK โ Cursor.models.list, ModelSelection, parameters (e.g. thinking levels), per-run sticky overrides.
Project, user, and team rules that the Cursor SDK and Agent load โ `.cursor/rules/*.mdc`, `AGENTS.md`, and the legacy `.cursorrules`. Use when authoring rules that the SDK will pick up via `local.settingSources`, or when writing rule frontmatter with the right type (always / auto-attached / agent-requested / manual).

MCP servers expose tools to the agent. Configure them on AgentOptions.mcpServers (or SendOptions.mcpServers for per-run override) as Record<string, McpServerConfig> โ the key is the server name.
