It gives any MCP client — Claude, Cursor, VS Code, Windsurf, Codex — **33 tools** for transactional email, contacts, campaigns, domains, and analytics, over stdio.\n\n## Setup\n\n**1. Get a useSend API key** (`us_…`) from **Settings → API Keys** at [app.usesend.com](https://app.usesend.com) (or your self-hosted instance).\n\n**2. Add the server to your MCP client.** Almost every client uses the same JSON — paste this in and swap in your key:\n\n```json\n{\n  \"mcpServers\": {\n    \"usesend\": {\n      \"command\": \"uvx\",\n      \"args\": [\"usesend-mcp\"],\n      \"env\": { \"USESEND_API_KEY\": \"us_your_api_key_here\" }\n    }\n  }\n}\n```\n\n`uvx` (from [uv](https://docs.astral.sh/uv/)) downloads and runs the server from PyPI on demand — nothing to install first.\n\n**Where does that JSON go?**\n\n| Client | Config file |\n|---|---|\n| Claude Code | `.mcp.json` (project root) |\n| Claude Desktop | `claude_desktop_config.json` |\n| Cursor | `.cursor/mcp.json` (project) or `~/.cursor/mcp.json` |\n| VS Code (Cline) | `cline_mcp_settings.json` |\n| Windsurf | `~/.codeium/windsurf/mcp_config.json` |\n\nPrefer the command line?\n\n```bash\nclaude mcp add usesend --env USESEND_API_KEY=us_your_api_key_here -- uvx usesend-mcp   # Claude Code\ncodex  mcp add usesend --env USE…","publisher":{"name":"gardenbaum","url":null},"homepage":"https://github.com/gardenbaum/usesend-mcp","repository":"https://github.com/gardenbaum/usesend-mcp/blob/main/CHANGELOG.md","version":"0.1.0","license":null,"protocols":["mcp"],"tags":["mcp","model-context-protocol","usesend","email","fastmcp","llm","ai"],"pricing":null,"endpoints":[{"url":"pypi:usesend-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"productivity.email","name":"Email","confidence":1,"provenance":"declared"},{"slug":"dev.terminal","name":"Terminal & Shell","confidence":0.825,"provenance":"derived"}],"categories":["dev","productivity"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"usesend-mcp","registry":"pypi","observedAt":"2026-09-10T15:25:01.785Z","publishedAt":"2026-07-04T06:05:53.407080Z","latestVersion":"0.1.0"}},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"usesend-mcp","url":"https://pypi.org/project/usesend-mcp/","firstSeenAt":"2026-09-10T15:22:59.338Z","fetchedAt":"2026-09-10T15:22:59.338Z","normalizedAt":"2026-09-10T15:22:59.338Z"}]},"firstSeenAt":"2026-09-10T15:22:59.338Z","updatedAt":"2026-09-10T15:25:01.785Z"}
