RISK

Why create_draft is rated Medium

This tool creates and modifies email drafts reversibly — the user can edit or discard them before sending. It does not execute code, delete data irreversibly, or move funds. The 'Write' category applies because it creates new data (draft emails) that can be undone.

From the tool's definition Tool description states 'Saves an email to the Mail.app Drafts folder' and 'Composes a new draft' with ability to pass `to`/`subject`/`body` and attach files. Creates email content that is 'never sends' but is created for user review.

RECOMMENDED RULE

The rule that runs create_draft safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Local, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_draft, this is the rule to start with:

create_draft Rate-limited

create_draft stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about create_draft

What does the create_draft tool do? +

Saves an email to the Mail.app Drafts folder for the user to review and send manually — never sends. Composes a new draft (pass to/subject/body), or a reply draft (pass reply_to_message_id plus body). On a multi-account Mac, pass account (an account name from list_email_accounts) or from (a sender address) to place the draft in that account's Drafts; otherwise it lands in the default account. Attach files by passing attachments (comma-separated absolute file paths, e.g. a PDF quote) — they are attached to the saved draft. Use this for the cautious user who wants AI-composed mail but insists on sending it themselves. It is categorised as a Write tool in the Local MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does create_draft accept? +

create_draft accepts 11 parameters: cc, to, bcc, body, from, account, subject, html_body, reply_all, attachments, reply_to_message_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on create_draft? +

Register the Local MCP server in PolicyLayer and add a rule for create_draft: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Local. Nothing to install.

What risk level is create_draft? +

create_draft is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_draft? +

Yes. Add a rate_limit block to the create_draft rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create_draft completely? +

Set action: deny in the PolicyLayer policy for create_draft. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create_draft? +

create_draft is provided by the Local MCP server (local-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
