MyAgentMail is built API-first with a CLI, an MCP server, a typed SDK, and a curated /llms.txt discovery file — so any agent (Claude, Cursor, Windsurf, Cline, ChatGPT, GitHub Copilot agent mode) can self-orient and start integrating without you writing a brief.
Copy this block and paste it as the first message to whichever agent you're using. It points the agent at our discovery surface; the agent takes it from there.
Build [describe what you want] using MyAgentMail. All documentation lives at https://myagentmail.com. Start by fetching https://myagentmail.com/llms.txt — that's the canonical agent-discovery file with curated links to every authoritative spec, the CLI, the SDK, the MCP server, and the example app. For one-fetch full context, use https://myagentmail.com/llms-full.txt — it inlines the SKILL manifest plus every reference doc into a single file (~1,700 lines). Per-endpoint docs are available as both HTML and markdown: - HTML index: https://myagentmail.com/docs - HTML per endpoint: https://myagentmail.com/docs/<group>/<operation> (e.g. /docs/domains/listdomains) - Markdown per endpoint: https://myagentmail.com/docs-md/<group>/<operation> — same content, no chrome, optimized for fetch+ingest. Prefer this when you need a single endpoint's schema + code samples without parsing HTML. Don't guess at endpoints, request shapes, or webhook payloads. The OpenAPI spec at https://myagentmail.com/openapi.yaml is authoritative. The skill manifest at https://myagentmail.com/skills/myagentmail/SKILL.md has the auth model and a working Quick Start in the first 80 lines. If an API key is required, I'll provide it separately — never paste it into chat or commit it. For LinkedIn-related work, read https://myagentmail.com/skills/myagentmail/references/linkedin.md before you start. For webhook integration, https://myagentmail.com/skills/myagentmail/references/webhooks.md covers HMAC verification. A reference open-source app — onboarding wizard, AI-inferred ICP, unified leads queue, dual-channel drafters — is at https://github.com/kamskans/myagentmail-outreach-starter. Read it as documentation, not as something to fork.
The seamless first-run path. `myagentmail mcp install` auto-detects every MCP host on the machine and wires it up — no JSON editing, no per-host docs. Cheaper in agent-token cost than MCP for long sessions (Claude Code, CI, terminal-based agents) because the surface is discovered lazily through --help. Includes `listen` for ngrok-free webhook tunneling and `doctor` for a one-shot health check.
npm install -g myagentmail-cli myagentmail login # opens browser, click Approve, done myagentmail mcp install # auto-wires Claude Desktop / Cursor / Windsurf / Claude Code
Drop into Claude Desktop, Cursor, Windsurf, Cline, or any MCP-compatible client. Adds ~25 typed tools spanning email + LinkedIn + signals.

}Drop our SKILL.md into your Claude project. The skill manifest is auto-loaded by Claude when relevant prompts appear, giving the agent our auth + capabilities + recipes for free.

When the agent writes actual code (vs. calling MCP tools or shelling out to the CLI), the typed SDK gives the cleanest shape. Auto-completes, infers types, surfaces docs inline.
npm install myagentmail
Every endpoint, every shape — as HTML for humans and markdown for agents. Each endpoint has a paired markdown alternate at /docs-md/<slug> with schema + code samples in TypeScript, Python, and curl. The OpenAPI spec is the source of truth underneath.
curl https://myagentmail.com/docs-md/domains/listdomains
These are the canonical discovery files. You don't need to read them yourself — your agent does. Listed here so you know what to point an agent at if it needs more than the briefing above.
.md alternate. Every API endpoint has one too at /docs-md/<slug> — schema, responses, and ready-to-run code samples in plain markdown. Skill docs and reference docs are already markdown at their canonical URL.<link rel="alternate" type="text/markdown" href="/llms.txt">. HTML-aware crawlers + agents discover the discovery file without needing a hard-coded URL.whsec_... secret and the X-MyAgentMail-Signature header.Building a developer product and want to think through your own DX-for-agents strategy?
