Privacy policy

Last updated July 15, 2026. Applies to the MCP Replay website, the MCP Replay iOS app, and the mcp-tape command line tool.

MCP Replay is built so that your traces are yours. There are no accounts, no analytics scripts, no advertising, and no tracking of any kind.

What stays on your device

• Traces you open from a file, drag into the browser, or record with mcp-tape are parsed locally, in your browser or on your phone. They are not uploaded anywhere by opening them.
• Live mode connects directly to mcp-tape running on your own computer, over your own network. The stream never touches our servers.
• The iOS app keeps a list of recently opened links on your device only. You can clear it by deleting the app.

What reaches our servers, and when

• Opening a shared link. Fetching a mcpreplay.dev/?trace= link requests that trace from our server, like loading any web page. We keep standard, short-lived server logs (Cloudflare) for abuse prevention. We do not build profiles from them.
• Sharing a trace. This is the only time trace content leaves your device, and it happens only when you press the share button and confirm. The trace is stored anonymously, is reachable by anyone who has the link, and expires after 30 days. You receive a one-time delete token to remove it sooner. mcp-tape redacts common secret shapes (API keys, bearer tokens) at record time, but you should review a trace before sharing it.

What we never do

• No analytics or telemetry in the app, the site, or the CLI.
• No accounts, so nothing is linked to your identity.
• No selling, sharing, or mining of trace content. Shared traces are stored to serve the link you created, nothing else.
• No third-party trackers, fonts, or CDNs on the site.

Data removal

Use the delete token shown when you shared a trace: DELETE https://mcpreplay.dev/api/trace/<id> with the X-Delete-Token header, or simply wait for the 30-day expiry. If you lost the token and need something removed, see the takedown page or email the address there.
