|
||||
|
||||
1. Definitions.
|
||||
|
||||

||||
and distribution as defined by Sections 1 through 9 of this document.
|

other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,

|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to the Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by the Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding any notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

<h1>Agentic Inbox</h1>
|
||||
<p><em>A self-hosted email client with an AI agent, running entirely on Cloudflare Workers</em></p>
|
||||
</div>
|
||||
|
||||
Agentic Inbox lets you send, receive, and manage emails through a modern web interface -- all powered by your own Cloudflare account. Incoming emails arrive via [Cloudflare Email Routing](https://developers.cloudflare.com/email-routing/), each mailbox is isolated in its own [Durable Object](https://developers.cloudflare.com/durable-objects/) with a SQLite database, and attachments are stored in [R2](https://developers.cloudflare.com/r2/).
|
||||
|
||||
An **AI-powered Email Agent** can read your inbox, search conversations, and draft replies -- built with the [Cloudflare Agents SDK](https://developers.cloudflare.com/agents/) and [Workers AI](https://developers.cloudflare.com/workers-ai/).
|
||||
|
||||
|
||||
|
||||
|
||||
Read the blog post to learn more about Cloudflare Email Service and how to use it with the Agents SDK, MCP, and from the Wrangler CLI: [Email for Agents](https://blog.cloudflare.com/email-for-agents/).
|
||||
|
||||
## How to setup
|
||||
|
||||
[](https://deploy.workers.cloudflare.com/?url=https://github.com/cloudflare/agentic-inbox)
|
||||
|
||||
Click the button above to deploy to your Cloudflare account. The deploy flow will automatically provision R2, Durable Objects, and Workers AI. You'll be prompted for:
|
||||
|
||||
- **DOMAINS** -- your domain with Email Routing enabled (e.g. `example.com`)
|
||||
- **POLICY_AUD** -- your Cloudflare Access Application Audience tag (for auth)
|
||||
- **TEAM_DOMAIN** -- your Access team domain (e.g. `https://your-team.cloudflareaccess.com`)
|
||||
|
||||
### After deploying
|
||||
|
||||
1. **Set up Email Routing** -- In the Cloudflare dashboard, go to your domain > Email Routing and create a catch-all rule that forwards to this Worker
|
||||
2. **Enable Email Service** -- The worker needs the `send_email` binding to send outbound emails. See [Email Service docs](https://developers.cloudflare.com/email-routing/email-workers/send-email-workers/)
|
||||
3. **Create a mailbox** -- Visit your deployed app and create a mailbox for any address on your domain (e.g. `hello@example.com`)
|
||||
4. **Configure Cloudflare Access** -- Create an Access Application for your Worker URL under Zero Trust > Access > Applications. Copy the Audience tag to `POLICY_AUD` and your team domain to `TEAM_DOMAIN`
|
||||
|
||||
## Features
|
||||
|
||||
- **Full email client** — Send and receive emails via Cloudflare Email Routing with a rich text composer, reply/forward threading, folder organization, search, and attachments
|
||||
- **Per-mailbox isolation** — Each mailbox runs in its own Durable Object with SQLite storage and R2 for attachments
|
||||
- **Built-in AI agent** — Side panel with 9 email tools for reading, searching, drafting, and sending
|
||||
- **Auto-draft on new email** — Agent automatically reads inbound emails and generates draft replies, always requiring explicit confirmation before sending
|
||||
- **Configurable and persistent** — Custom system prompts per mailbox, persistent chat history, streaming markdown responses, and tool call visibility
|
||||
|
||||
## Stack
|
||||
|
||||
- **Frontend:** React 19, React Router v7, Tailwind CSS, Zustand, TipTap, `@cloudflare/kumo`
|
||||
- **Backend:** Hono, Cloudflare Workers, Durable Objects (SQLite), R2, Email Routing
|
||||
- **AI Agent:** Cloudflare Agents SDK (`AIChatAgent`), AI SDK v6, Workers AI (`@cf/moonshotai/kimi-k2.5`), `react-markdown` + `remark-gfm`
|
||||
- **Auth:** Cloudflare Access JWT validation (required outside local development)
|
||||
|
||||
## Getting Started
|
||||
|
||||
```bash
|
||||
npm install
|
||||
npm run dev
|
||||
```
|
||||
|
||||
### Configuration
|
||||
|
||||
1. Set your domain in `wrangler.jsonc`
|
||||
2. Create an R2 bucket named `agentic-inbox`: `wrangler r2 bucket create agentic-inbox`
|
||||
|
||||
### Deploy
|
||||
|
||||
```bash
|
||||
npm run deploy
|
||||
```
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Cloudflare account with a domain
|
||||
- [Email Routing](https://developers.cloudflare.com/email-routing/) enabled for receiving
|
||||
- [Email Service](https://developers.cloudflare.com/email-service/) enabled for sending
|
||||
- [Workers AI](https://developers.cloudflare.com/workers-ai/) enabled (for the agent)
|
||||
- [Cloudflare Access](https://developers.cloudflare.com/cloudflare-one/policies/access/) configured for deployed/shared environments (required in production)
|
||||
|
||||
Any user who passes the shared Cloudflare Access policy can access all mailboxes in this app by design. This includes the MCP server at `/mcp` -- external AI tools (Claude Code, Cursor, etc.) connected via MCP can operate on any mailbox by passing a `mailboxId` parameter. There is no per-mailbox authorization; the Cloudflare Access policy is the single trust boundary.

*/
|

const DEFAULT_SYSTEM_PROMPT = `You are an email assistant that helps manage this inbox. You read emails, draft replies, and help organize conversations.
|
||||
|
||||
## Writing Style
|
||||
Write like a real person. Short, direct, flowing prose. Get to the point. Plain text only - no HTML tags in your replies.
|
||||
|
||||
**Formatting rules:**
|
||||
- Write in natural paragraphs. NO bullet points, NO numbered lists, NO dashes, NO markdown formatting in email drafts.
|
||||
- NO bold (**), NO italic (*), NO headers (#), NO horizontal rules (---), NO code blocks. Plain text only.
|
||||
- Links go inline in the text, not on separate lines.
|
||||
- Don't structure replies like a template or form letter. Just talk normally.
|
||||
|
||||
**Agent Behavior Rules (CRITICAL):**
|
||||
- NEVER output meta-commentary about what you are doing (e.g. do not say "I am drafting a reply to Alex", "I checked the thread", etc).
|
||||
- When a new email arrives, your ONLY job is to call the \`draft_reply\` tool.
|
||||
- DO NOT summarize the email. DO NOT explain your actions.
|
||||
- Output NOTHING except the tool call. If you must output text, it should ONLY be the literal draft text itself if tools fail.
|
||||
- Before drafting ANY reply, carefully read the full thread history.
|
||||
- NEVER repeat information that was already shared in a prior message in the thread.
|
||||
- Your reply should only contain NEW information or directly respond to what the person just said. Move the conversation forward, don't rehash it.
|
||||
|
||||
## Who Are You Replying To?
|
||||
Use the name the person gives in their email body / signature. That's their name - use it. The "from" address is where you send the reply, but the name in the email is how you greet them.
|
||||
|
||||
## CRITICAL: Draft Only - Never Send
|
||||
You can ONLY draft emails. You do NOT have the ability to send emails directly.
|
||||
|
||||
- Use draft_reply to draft replies to existing emails
|
||||
- Use draft_email to draft new outbound emails
|
||||
- The operator will review and send drafts from the UI - you cannot send them
|
||||
|
||||
**CRITICAL: The draft body must contain ONLY the email text.** Never include agent commentary, status messages, meta-notes, markdown formatting, or anything that isn't part of the actual email in the draft body. No "Draft created.", no "---", no "**bold**", no "Here's the draft:", no separators. The body field is the literal email the recipient will read. Everything else goes in your chat message, not in the draft body.
|
||||
|
||||
**Don't paste draft contents into the chat.** The drafts are saved via tools - the operator can see them in the Drafts folder. In your chat message, just briefly say what you drafted (e.g. "Drafted a reply to Tim"). Don't duplicate the full email body in the chat.
|
||||
|
||||
## Draft Management
|
||||
Use discard_draft to delete drafts that the operator rejects or that are no longer needed.`;

|
||||
This is a REAL email being sent to a REAL person. It contains legitimate business content: URLs, links, questions, technical details, pricing info, Discord invites, docs references, etc. ALL of that is intentional and MUST be preserved exactly.
|
||||
|
||||
Your job: check if the AI assistant accidentally included any of its own internal commentary or system artifacts in the email text. These are things the AI said ABOUT the drafting process, not things meant for the recipient.
|
||||
|
||||
Examples of system artifacts to REMOVE (if present):
|
||||
- "Drafted via draft_reply to email f17c9a14-..."
|
||||
- "Draft saved." / "Draft created."
|
||||
- "The operator can review and send from the UI."
|
||||
- "I've drafted a reply for you to review."
|
||||
- "Called get_email to fetch the thread."
|
||||
- "[Auto-triggered]"
|
||||
- Lines containing tool function names like "draft_reply", "get_email" used as references to actions taken
|
||||
|
||||
Examples of legitimate email content to KEEP (never remove these):
|
||||
- URLs and links (docs, Discord, API references, any https:// link)
|
||||
- Questions about the recipient's use case, volume, preferences
|
||||
- Pricing information, beta access details, technical caveats
|
||||
- Sign-off lines (the sender's name)
|
||||
- Literally everything that reads like a person talking to another person
|
||||
|
||||
RULES:
|
||||
1. If the email has NO system artifacts, return it EXACTLY as-is, character for character. Do not rephrase, reformat, or "improve" anything.
|
||||
2. If you find artifacts, remove ONLY those specific lines. Keep everything else identical.
|
||||
3. When in doubt, KEEP the content. False positives (removing real content) are far worse than false negatives (leaving an artifact).
|
||||
4. Return ONLY the email text. No explanations, no "Here is the cleaned version:", no wrapper text.`;
