What it is
The Mosra connector lets Claude (claude.ai, Claude Desktop and Claude Code) work inside your Mosra account. You ask in plain language, Claude finds the right deck, makes small edits and hands you back a link to open in the editor.
It is a remote connector: nothing to install or run on your computer. Claude talks to Mosra over HTTPS, signed in as you, with only the permissions you grant.
Claude never sees your Mosra password. It cannot change your account settings or payment details, and it cannot delete your account.
Connect Claude to Mosra
Add the connector
- In claude.ai, open Settings, then Connectors, and choose to add a custom connector.
- Enter the address https://mcp.mosra.app/mcp and save. If you use Claude Code or a team plugin marketplace, install the Mosra plugin instead; it points to the same address.
- Claude opens a Mosra page asking you to allow access. Sign in to Mosra if asked.
- On the Allow screen, review the permissions. Sensitive ones are switched off by default and you can grant less than Claude asks for. Choose Allow.
- You are sent back to Claude. Ask it something like: Make a 6-slide deck about our Q3 results in Mosra.
If your organisation manages Claude for you, an administrator may need to add the connector first. You need a Mosra account to allow access.
Disconnect
Open Mosra, then Settings, then Connected apps, and choose Disconnect next to Claude. Access stops immediately. Connecting again means answering the Allow screen again.
What Claude can do
| Area | Examples |
|---|---|
| Decks | List, create (slides or cards; 16:9, 16:10, 4:3, 1:1), rename, duplicate, move, trash and restore. |
| Slides | Read the outline, read or replace a slide, add text and images, change one shape, reorder, speaker notes, background, animation, motion paths and transitions. |
| Design | Shape catalog, brand kit and fonts, layout guidance. |
| Interactive and quizzes | Click-to-reveal answers, flip cards, tabs and hotspots; graded questions (multiple choice, true/false, short answer and more) made by copying a template's sample question slide and setting the right answers, points and attempts; simple games built from a game-like template or step by step. It cannot play a deck for you: open it in the editor to try it. |
| Templates | Start from one of Mosra's ready-made templates (business decks, lessons, worksheets, certificates, invitations, card decks). Claude offers a few that fit, or picks the best one, and writes your content into it. You can also submit your own deck to the community template gallery; Claude asks first, and a moderator reviews it before anyone else sees it. |
| Media | Upload an image from a link, search stock photos, manage your library. |
| Sharing | Visibility, link access, collaborators and comments (read, add, reply, resolve). |
| Export | Share, present and embed links; video and LMS packages where they are enabled for your plan. |
| Account | Your plan, credit balance and notifications. |
Example prompts
Say what you want the way you would to a colleague. Some that work well:
- Make a 6-slide deck about our Q3 results in Mosra. Title slide, three key numbers, what went well, what did not, next steps.
- Open my Onboarding deck and rewrite slide 3 to be shorter. Keep the heading.
- Apply my brand colours and fonts to the Sales kickoff deck.
- List the unresolved comments on my Product roadmap deck and reply to each one that is a question.
- Add a photo of a city skyline to the last slide of the Investor update deck, with alt text.
- Turn the notes in my Photosynthesis deck into a 10-question multiple-choice quiz.
- Make a click-to-reveal flashcard slide for each of these five terms.
- Give me a share link for the Q3 review deck, viewable by anyone with the link.
Claude asks before anything destructive and before changing who can see a deck.
Permissions
The Allow screen lists what Claude asks for. You can grant less; Claude then works with what it has and tells you when something needs a permission you did not give.
| Permission | Lets Claude |
|---|---|
| Read your decks | See your presentations, slides, comments and outlines. |
| Edit your decks | Create, change and delete slides and presentations. Deleted decks go to the trash. |
| Add media | Upload images and other files to your library. |
| Read workspaces | See your workspaces, folders, teams and brand kits. |
| Manage workspaces | Create folders and change workspace and sharing settings. |
| Read your account | See your name, plan and credit balance. |
Safety and your data
- You are in control. Every grant can be revoked in Settings, Connected apps, and revoking takes effect immediately.
- Access tokens are stored hashed, expire after one hour and are refreshed automatically while the connection is active.
- Mosra records that a tool ran (its name, the time and whether it succeeded). It does not store the content Claude sent or received through the connector.
- Deleting a deck moves it to the trash, where you can restore it. Actions that delete, change who can see a deck or publish one to the community gallery are marked so Claude asks you first.
What Claude reads from Mosra becomes part of your conversation with Claude and is handled under Anthropic's terms and privacy policy. Mosra's own Privacy Policy and Terms apply to your account and your content.
Troubleshooting
Claude says it cannot reach Mosra, or asks me to sign in again
Remove the connector in Claude, add it again and answer the Allow screen. If you disconnected Claude in Connected apps, this is also how you reconnect.
Deck not found
Claude can only see decks you can open in Mosra, and only if you allowed it to read them. Ask it to list your decks, check the name, and make sure the Read your decks permission is granted. A deck in the trash has to be restored first.
The deck changed while Claude was editing
If you or a collaborator edit the same slide at the same moment, Claude re-reads the deck and applies its change again. Ask it to try once more if it stops.
A permission is missing
If you left a permission off, Claude will say what it could not do. Disconnect Claude in Connected apps and connect again to grant it.
Support
Write to support@mosra.app with what you asked Claude to do and what happened. Do not send your password or access tokens; we never need them.
