One click. Sign in once. Your assistant can search, save, and tag your links. No API keys to copy.
Uncheck “Allow changes” when you connect and the assistant can look but not touch: search, list, read one link, list tags, get your overview stats, run a digest, and preview duplicates. Every write tool — save, edit, tag, delete, merge — refuses with a clear message.
Good for a shared assistant, a first try, or anyone who wants their crypt browsable but not editable.
Every client talks to the same endpoint: https://mcp.getlinkcrypt.com/mcp
https://mcp.getlinkcrypt.com/mcpRun this in your terminal:
claude mcp add --transport http linkcrypt https://mcp.getlinkcrypt.com/mcpThen run /mcp and follow the prompt to sign in and approve.
https://mcp.getlinkcrypt.com/mcphttps://mcp.getlinkcrypt.com/mcpDeveloper mode needs a ChatGPT plan that supports it (Plus, Pro, Business, Enterprise, or Edu).
Add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"linkcrypt": {
"url": "https://mcp.getlinkcrypt.com/mcp"
}
}
}Add this to .vscode/mcp.json:
{
"servers": {
"linkcrypt": {
"type": "http",
"url": "https://mcp.getlinkcrypt.com/mcp"
}
}
}Add this to ~/.codeium/windsurf/mcp_config.json:
{
"mcpServers": {
"linkcrypt": {
"serverUrl": "https://mcp.getlinkcrypt.com/mcp"
}
}
}Run this in your terminal, then authenticate when prompted:
gemini mcp add --transport http linkcrypt https://mcp.getlinkcrypt.com/mcp14 tools, thin wrappers over the same REST API. Write tools need “Allow changes”; destructive ones always ask you to confirm.

When you approve a connection you choose whether to check “Allow this assistant to make changes.” Leave it on for full read/write access, or turn it off for a read-only connection that can look but never save, edit, tag, or delete anything.
Every connected assistant shows up under Preferences → Connected AI assistants, with when it connected and when it was last used. Click Disconnect there, or disconnect from the client itself — either way, access is revoked immediately and the assistant needs a fresh sign-in and approval to reach your crypt again.
Tool inputs and outputs pass through whichever assistant you're using — Anthropic, OpenAI, or another vendor — the same way any tool call does. Link Crypt only sees the calls your assistant actually makes, same as a REST API key. Details in our privacy policy.

No. The MCP server is included with every plan and every trial, the same as the REST API.
Only if you allowed changes when you connected, and only when it asks you to confirm first. It never deletes anything as a side effect of another request.
Not directly — Obsidian doesn't speak MCP yet. See the Obsidian + AI guide for the pattern most people use instead.
A Link Crypt account with an active subscription or trial, and an MCP-capable client (Claude, ChatGPT, Cursor, VS Code, Windsurf, Gemini CLI, or anything else that speaks the standard remote MCP protocol). No API key to generate or paste.
