From 95e7d963b93586a15ba0e256d10ea8ffa8fc5782 Mon Sep 17 00:00:00 2001 From: MultiMail Date: Thu, 11 Jun 2026 21:30:31 -0400 Subject: [PATCH 1/2] =?UTF-8?q?release:=20v0.13.0=20=E2=80=94=20AI=20discl?= =?UTF-8?q?osure=20is=20gateway-enforced=20(EU=20AI=20Act=20Article=2050)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Removed the ai_disclosure parameter from create_mailbox, update_mailbox, and configure_mailbox. AI transparency marking — the signed ai_generated claim, the X-AI-Generated header, and the visible disclosure footer — is injected at the send gateway on every agent-originated email and can no longer be disabled. API calls setting ai_disclosure:false are rejected with 400. --- CHANGELOG.md | 10 +++------- package.json | 2 +- server.json | 6 +++--- src/index.ts | 35 +++++------------------------------ 4 files changed, 12 insertions(+), 41 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 45031ab..d5b4b2e 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -2,15 +2,11 @@ All notable changes to `@multimail/mcp-server` will be documented in this file. -## 0.12.0 — 2026-06-11 +## 0.13.0 — 2026-06-11 -### Added — DID onboarding via MCP +### Changed — AI disclosure is now gateway-enforced (EU AI Act Article 50, GHST-450) -New `request_did_challenge` tool: request an account-binding challenge for an Ed25519 `did:key` before signup. `create_account` now accepts optional `agent_did` + `did_challenge_id` + `did_signature` (all three together) to bind a verifiable agent identity to the account at activation. - -### Changed — operator-approval two-step flows - -`update_account` (for `oversight_email` changes) and `delete_account` now accept an optional `approval_code`.

Previously these flows could not be completed from MCP. +Removed the `ai_disclosure` parameter from `create_mailbox`, `update_mailbox`, and `configure_mailbox`. AI transparency marking — the signed `ai_generated` claim in `X-MultiMail-Identity`, the `X-AI-Generated: true` header, and the visible disclosure footer line — is injected at the send gateway on every agent-originated email and can no longer be disabled. API calls setting `ai_disclosure: false` are rejected with 400; `true` is accepted as a no-op. Templated system notifications (not AI-generated content) remain unmarked. ## 0.11.0 — 2026-06-07 diff --git a/package.json b/package.json index b5cf9c4..39f8868 100644 --- a/package.json +++ b/package.json @@ -1,6 +1,6 @@ { "name": "@multimail/mcp-server", - "version": "0.12.0", + "version": "0.13.0", "description": "Give your agent its own email address with graduated human oversight — from full approval to autonomous sending.", "type": "module", "bin": { diff --git a/server.json b/server.json index 74dd236..3cbf341 100644 --- a/server.json +++ b/server.json @@ -6,12 +6,12 @@ "url": "https://github.com/multimail-dev/mcp-server", "source": "github" }, - "version": "0.12.0", + "version": "0.13.0", "packages": [ { "registryType": "npm", "identifier": "@multimail/mcp-server", - "version": "0.12.0", + "version": "0.13.0", "transport": { "type": "stdio" }, @@ -39,4 +39,4 @@ "url": "https://mcp.multimail.dev/mcp" } ] -} \ No newline at end of file +} diff --git a/src/index.ts b/src/index.ts index 488a3dc..ff5abc9 100644 --- a/src/index.ts +++ b/src/index.ts @@ -119,7 +119,7 @@ function getMailboxId(argsMailboxId?: string): string { const server = new McpServer({ name: "multimail", - version: "0.12.0", + version: "0.13.0", }); // --- No API key: single setup tool --- @@ -1074,7 +1074,7 @@ if (API_KEY) { idempotentHint: true, }, description: - "Update mailbox metadata: display name and signature block.
