What it does

E2a Setup is an agent skill from tokencanopy/e2a. Use when a user wants to connect or authorize the e2a MCP server, select or create an agent inbox, verify first-run readiness, or set up a custom email domain. Guides native client OAuth, shared-domain onboarding, and confirmed DNS-provider assistance without changing application code.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/clients.md` and `references/custom-domains.md`).

It sits in Backend & APIs, covering Email management, Transactional email and OAuth and OpenID Connect. It works with Model Context Protocol. The repository describes itself as: Open-source email API for applications and AI agents. Managed hosting at e2a.dev, or self-host with Docker. The licence is Apache-2.0.

When your agent uses it

  • A user wants to connect
  • Authorize the e2a MCP server
  • Create an agent inbox
  • Verify first-run readiness

Example prompts

  • “/e2a-setup”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Inspect the current client's tool registry for e2a tools.
  2. If absent, first check whether the plugin is disabled or needs a reload before offering manual registration; do not create a duplicate…
  3. Only if registration is genuinely absent, explain the native flow from clients.md, confirm before a client-config write, then offer to…
  4. Complete the client's OAuth flow, reload or restart if required, then call the e2a MCP whoami tool — never Unix or shell whoami. Treat…

What it can do on your machine

Read from SKILL.md and the folder at commit 776fe2c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.e2a.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

E2a Setup loads about 820 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 74 tokens; SKILL.md has 430 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~74
When it runs · the whole SKILL.md, loaded when a task matches
~820
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when a user wants to connect or authorize the e2a MCP server, select or create an agent inbox, verify first-run readiness, or set up a custom email domain. Guides native client OAuth, shared-domain onboarding, and confirmed DNS-provider assistance without changing application code.

Set up e2a

Boundaries

  • This skill starts after the e2a plugin is installed; it cannot bootstrap the plugin that contains it.
  • Do not change client configuration, create an inbox, or change DNS without the confirmation stated below. Use OAuth and never ask an interactive user for an API key.
  • Do not change application code. Never send a test unless the user selects its recipient.

MCP bootstrap

  1. Inspect the current client's tool registry for e2a tools.
  2. If absent, first check whether the plugin is disabled or needs a reload before offering manual registration; do not create a duplicate registration.
  3. Only if registration is genuinely absent, explain the native flow from clients.md, confirm before a client-config write, then offer to register https://api.e2a.dev/mcp.
  4. Complete the client's OAuth flow, reload or restart if required, then call the e2a MCP whoami tool — never Unix or shell whoami. Treat auth failures as reauthorization; preserve configuration for operational failures.

Select or create the inbox

  1. For agent scope, use the agent_email from whoami.
  2. For account scope, call list_agents: honor an inbox named by the task, use the sole result, or ask the user to choose among several.
  3. If none exists, defer inbox creation until the user chooses a shared or custom domain below.

Choose shared or custom domain

Ask whether the user wants the recommended shared domain or a custom domain.

  • Shared: offer an address on agents.e2a.dev, confirm the full address, then call create_agent.
  • Custom: confirm ownership and branded-address intent, then follow custom-domains.md. After verification and one user-driven post-verification get_domain capability read show the inbound and outbound state. If ready, ask for and show the complete branded address, obtain confirmation, then call create_agent. If not ready, report the precise resume step; do not poll.

Use a Cloudflare API MCP server when available for Cloudflare-hosted DNS. For GoDaddy, use the authenticated gddy path; the official GoDaddy MCP is read-only and cannot modify DNS.

Before any provider-assisted DNS write, show the complete proposed DNS diff and obtain one confirmation for the complete DNS diff.

Verify readiness

After selecting or creating the inbox, call list_messages (pass its email for account scope). This harmless read must succeed before readiness is claimed. Offer a send test only after the user selects a recipient; otherwise do not send one. Once the inbox read succeeds, resume the user's original request.

Completion report

Report the MCP registration and OAuth state, credential scope, selected inbox, successful inbox read, and domain state. For a custom domain, report inbound verification and outbound branded-sending capability separately, including any pending DNS or propagation action.
