--- name: mcp description: Connect an AI coding client to the Arcjet MCP server at https://api.arcjet.com/mcp. Use when the client has built-in MCP support or the CLI is not available. license: Apache-2.0 compatibility: AI clients that support remote MCP over HTTP / OAuth. metadata: author: arcjet type: core library: "@arcjet/skills" library_version: "1.13.0" # x-release-please-version sources: - docs/mcp.md --- # Arcjet MCP server Endpoint: `https://api.arcjet.com/mcp` only. OAuth on first connect. Enable write confirmations. Prefer `@arcjet/skills#cli` when a terminal is available. **Cursor** — `.cursor/mcp.json`: ```json { "mcpServers": { "arcjet": { "type": "streamable-http", "url": "https://api.arcjet.com/mcp" } } } ``` **VS Code** — `.vscode/mcp.json` with `"type": "http"` and the same URL. **Claude Code:** ```bash claude mcp add arcjet --transport http https://api.arcjet.com/mcp ``` Bootstrap: `list-teams` → `list-sites` → `get-site-key` → write `ARCJET_KEY`. Investigate: `analyze-traffic`, `list-requests`, `list-guards`, `investigate-ip`. Remote rules: `create-rule` (DRY_RUN) → `get-dry-run-impact` → `promote-rule`. Guard policies (MCP-only; no CLI commands): `list-guard-policies` → `describe-guard-policy` → `validate-guard-policy` → `put-guard-policy`. Application policies select by `label` / `action`. Coding-agent policies attach by **Execute on** (Tool call or Prompt).
