Common questions
Is Jam safe?
It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 3 days ago, and the latest version (1.36.3) reached the registry 9 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

Jam skills
Your agent sees what you saw, and shows you what it did.
npx skills add jamdotdev/skillsThen paste a Jam link and say what you want:
- "fix this https://jam.dev/c/…"
- "do what I said in this jam"
- "make a ticket for this jam"
- "record a jam showing it works"
A Jam is a screen recording or screenshot with the console logs, network requests and user actions attached, on one link. You'd record one for a bug report, a feedback walkthrough or a demo. These skills let your agent read a Jam, and record its own when it's done, so you check the result by watching it.
Works with Claude Code, Cursor, Codex, GitHub Copilot, Gemini CLI, OpenCode and every agent skills.sh supports. Add --skill jam-fix to install one skill.
Skills
You don't need to remember these names. Paste a Jam link, say what you want, and your agent picks the skill.
Give your agent a Jam
- jam: "Take a look at this jam." For a link with no instructions. It reads the Jam and picks the skill below that fits.
- jam-fix: "Fix this jam." Finds the root cause from the errors, failed requests and steps in the recording, and shows the evidence. It changes code only when you ask.
- jam-to-tasks: "Do what I said in this jam." Turns your feedback into a numbered to-do list, each item tied to the moment you said it, then works through it.
- jam-to-e2e: "Write a test for this jam." Writes an end-to-end test with your project's own test setup. A Jam of a bug becomes a test that fails until the fix lands.
- jam-to-ticket: "Make a ticket for this jam." Files it in Linear, GitHub Issues or Jira with the steps, a frame from the recording and the errors, unless a ticket already exists.
- video-to-jam: "Split this recording by bug." Turns an MP4, a Loom download or a long call into one Jam per issue.
Get a Jam back
- jam-proof: "Record a jam showing it works." Records the change working and gives you a Jam link for the pull request.
- jam-annotate: "Mark what's broken and share it." Draws boxes, arrows and notes on a screenshot, blurs anything private, and shares it as a Jam.
- jam-proof-table: "Give me the jams for each fix." After a batch of work, one table: each claim, whether it works, and the Jam that shows it.
Set up Jam
- jam-setup: "Set up jam." Installs the Jam CLI, signs you in, connects Jam MCP, installs these skills and runs
jam doctor, in that order. It asks once whether to set up this project or every project on your machine.
Make a video
These need no Jam account. With the Jam CLI, a video can become a Jam link to comment on.
- record-demo: "Record a demo of this feature." Plays the flow in a browser at human pace and renders a narrated 1440p video, with the camera moving only where the script says.
- add-voiceover: "Add a voiceover to this video." Writes a script for the ear, voices it line by line and lays each line on the moment it describes, with a subtitle file.
- record-terminal-proof: "Record proof that the migration ran." Records the commands and renders a GIF that plays inline on the pull request.
Requirements
- A free Jam account, for every skill except the three video skills.
- The Jam CLI. Say "set up jam" and
jam-setupwalks you through it. A skill signs in when it needs to.jam,jam-fixandjam-to-e2ecan read a Jam through Jam MCP instead, the Model Context Protocol (MCP) server the plugin connects. - For
video-to-jam: ffmpeg and a local transcriber such as Whisper. - For
record-demo: agent-browser 0.38.1 or later, ffmpeg and Node 22 or later, with no npm packages. Its narration comes fromadd-voiceover. - For
add-voiceover: ffmpeg and Node 22 or later, with no npm packages. An ElevenLabs key or the free Kokoro model (Python 3 and uv) gives a natural voice; without either, it uses the macOS voice. - For
record-terminal-proof: asciinema 3 and agg. On Windows, use WSL. - In CI or a cloud agent: a personal access token in
JAM_TOKEN. - For
jam-proof: recording a web page needs only Chrome. Recording a window or the whole screen needs macOS or Linux (X11).
Install as a plugin
The plugin installs every skill, connects Jam MCP and updates itself. Use the plugin or npx skills add, not both, or the agent sees every skill twice.
Claude Code
/plugin marketplace add jamdotdev/skills/plugin install jam@jam-plugins
Skills load as /jam:jam-fix, /jam:jam-proof, and so on. To test a checkout, run claude --plugin-dir /path/to/skills.
Cursor
Open Customize in the sidebar, search for Jam, and click Install.
To test a checkout, link it into the local plugin folder and run Developer: Reload Window:
ln -s /path/to/skills ~/.cursor/plugins/local/jamCodex
codex plugin marketplace add jamdotdev/skillscodex plugin add jam@jam-plugins
Start a new session, complete the OAuth prompt, and run /mcp to check the connection. To test a checkout, pass its path to marketplace add.
GitHub Copilot CLI
copilot plugin marketplace add jamdotdev/skillscopilot plugin install jam@jam-plugins
Gemini CLI
gemini extensions install https://github.com/jamdotdev/skillsRun /mcp auth Jam once to sign in. To test a checkout, run gemini extensions link /path/to/skills.
Sign-in, tokens, what Jam MCP can do, and permissions: docs/plugin.md.
