Save This One is a free bookmark manager with a live remote MCP server and a documented HTTP API. Claude, Claude Code, Cursor, supported ChatGPT plans, Windsurf Cascade, Grok, and other OAuth-capable MCP clients can save, search, tag, archive, and comment on bookmarks through the same account you use on the web.

Why bookmarks belong in an agent workflow
An assistant surfaces a useful article during a research or coding session. Without an integration, keeping it means changing context, copying a URL, opening another app, and filing it manually. Retrieval is just as awkward: the assistant cannot use references you saved last week unless you paste them back into the conversation.
MCP turns the library into a set of explicit tools. The assistant still acts only when asked, and OAuth scopes every call to the signed-in Save This One account.
What the MCP server can do
| Job | MCP tool |
|---|---|
| Save a public URL | save_bookmark |
| Search titles, URLs, tags, and notes | search_bookmarks |
| Browse bookmarks or tags | list_bookmarks, list_tags |
| Organize links | create_tag, tag_bookmarks, archive_bookmark |
| Add context | add_comment |
| Confirm the connected account | whoami |
Saving uses the same metadata and reader extraction pipeline as the web app. Destructive tools are marked as destructive so a compatible client can ask for confirmation.
Connect an AI client
The remote endpoint is:
https://mcp.savethisone.com/mcpAdd it as a remote Streamable HTTP MCP server, then complete the browser OAuth flow. Use the client-specific guide because menus, plan eligibility, and tool support differ:
- Claude custom connector
- Claude Code
- Cursor
- ChatGPT developer mode
- Windsurf Cascade
- Grok
- Grok Bot, sometimes searched as Grokbot
Start with whoami and a read-only search. That confirms the account and connection before the assistant writes anything.
The HTTP API remains useful
MCP is the best fit for compatible assistants. The REST API is better for scripts, launchers, scheduled jobs, and tools that can send HTTP requests but do not speak MCP. The terminal integration guide includes working examples with per-account API tokens.
Both routes write to one library. A link saved from Claude can be found later in Cursor, the web app, Raycast, or a script.
Current limits
Search is keyword-based across bookmark metadata, tags, and notes; this is not vector or semantic search. Save This One also does not promise a permanent archived copy of every page. MCP client availability can depend on plan and workspace policy—particularly in ChatGPT, Grok, and organization-managed products.
Frequently asked questions
Does Save This One have MCP support?
Yes. The remote OAuth-secured server is live at https://mcp.savethisone.com/mcp.
Is MCP access free?
Save This One does not charge for MCP access. Your AI client may require its own paid plan for custom connectors.
Can an assistant delete bookmarks?
The server exposes a delete tool and marks it destructive. Require explicit confirmation in the client before destructive actions.
Is this the same as giving an assistant my password?
No. The client completes OAuth and receives scoped access for the connected account. The MCP server never asks you to paste a password or API token into chat.
