Claude Desktop MCP Server for Bookmarks (2026 Setup Guide)

Set it up in Claude Desktop

Use the right ContextBolt account Sign into the extension with your account email and email code. If Pro is not active yet, save your license key once in Settings under Account. Let cloud sync finish. Use this same email when connecting your AI app.
Add a custom connector In Claude, go to Customize, then Connectors, click the + button, choose Add custom connector, and enter https://api.contextbolt.app/mcp. Leave every option below the URL as Claude fills it in, including the OAuth client, and press Add. Claude marks one option Recommended, Use Anthropic's hosted client metadata, but our server does not support it, so keep the one Claude selected. Use the remote Connectors UI, not claude_desktop_config.json. Free plans can add one custom connector. On Team and Enterprise plans, an Owner adds it first under Organization settings, then Connectors. Availability depends on your Claude account and workspace.
Sign in and approve Sign in on the ContextBolt page with your Pro extension account email, enter the email code, and approve the connection.
Check the connection Start a fresh chat or session and ask what bookmark tools are available. If the library looks empty, check that the extension and the AI connection use the same email, Pro is active, and cloud sync has finished.

What to ask it

“Search my bookmarks for anything about API rate limiting” Claude searches your entire bookmark collection semantically. Even if none of your saves mention 'rate limiting' exactly, it will find related content about API throttling, request limits, or usage quotas.

“What did I save on Twitter about startup fundraising?” You can filter by platform. Claude will search only your Twitter/X bookmarks and return saved tweets about fundraising, investor pitches, or seed rounds.

“Find my saved Reddit posts about Python testing frameworks” Combines platform filtering with topic search. Claude returns your Reddit saves that discuss pytest, unittest, or testing best practices in Python.

“I'm writing about MCP. What relevant content have I bookmarked?” Use this pattern when working on a specific topic. Claude pulls in all your saved content related to MCP, giving you a research starting point from your own curated collection.

ContextBolt in Claude Desktop: the full guide

Connect with OAuth. Use https://api.contextbolt.app/mcp, then sign in with your Pro extension account email, enter the email code, and approve access. Existing personal URLs still work for older clients. Full setup and recovery help.

On the Add custom connector screen, leave every option below the URL as Claude fills it in and press Add. Claude marks one option Recommended, Use Anthropic’s hosted client metadata, but our server does not support it, so keep whichever option Claude selected.

Claude Desktop is Anthropic’s native macOS and Windows app for Claude. It supports MCP (Model Context Protocol), which means you can give Claude direct access to external tools and data sources, including your ContextBolt bookmarks.

Once connected, you can ask Claude to search your saved web pages and your saves from Twitter/X, Reddit and LinkedIn during any conversation. This is particularly useful when you’re researching a topic and want to pull in articles, threads, or posts you’ve previously saved.

What the Claude Desktop integration gives you

Most people save content with good intentions but never find it again. The Claude Desktop integration solves this by making your bookmarks searchable from inside your AI conversations.

Instead of switching between Claude and your browser extension to look things up, you can ask Claude directly. It searches your bookmarks semantically, meaning it finds relevant content even when the exact words don’t match your query.

This is especially powerful for research workflows. If you’re writing about a topic and want to reference things you’ve previously saved, Claude can pull them in without you leaving the conversation.

Why Claude Desktop uses the Connectors UI, not the config file

Most MCP setup guides start by telling you to edit claude_desktop_config.json. That file is genuinely useful, but only for local servers that run as a process on your machine, started by Claude Desktop with a command field. ContextBolt’s MCP endpoint is hosted on api.contextbolt.app and reached over HTTPS, which the local config file does not support today.

Anthropic’s custom connectors guide describes servers in claude_desktop_config.json as a separate mechanism for local servers. Remote servers are added in Claude itself, under Customize, then Connectors, then the + button and Add custom connector. On Team and Enterprise plans an Owner adds the connector first, under Organization settings, then Connectors. Free plans can add one custom connector.

Once added through Connectors, the desktop app inherits the connection from your account. There is nothing else to configure on the local machine.

Tips for getting the most from the Claude Desktop integration

Be specific with platform filters: If you know the content was a tweet, mention Twitter in your prompt. This narrows the search and returns more relevant results.

Use natural language: The search is semantic, so describe what you’re looking for in plain English rather than trying to guess exact keywords.

Combine with Claude’s analysis: Ask Claude not just to find bookmarks but to summarize or compare them. For example: “Find my saved articles about MCP and summarize the key differences in their approaches.”

Save broadly, search narrowly: The more content you save across platforms, the more useful this integration becomes. ContextBolt works best as a catch-all for interesting content that you search through later.

Frequently asked questions

Something else on your mind? Get in touch.

Why can't I add ContextBolt to claude_desktop_config.json directly?

That file only supports local stdio servers, ones that run as a process on your machine. ContextBolt is a remote HTTP server hosted on api.contextbolt.app, so it goes through Customize, then Connectors in Claude (claude.ai/customize/connectors on the web). Anthropic's custom connectors guide describes claude_desktop_config.json as a separate mechanism for local servers.

Do I need a ContextBolt Pro subscription for Claude Desktop integration?

Yes. MCP is a Pro feature ($6/month). The free Basic tier includes AI tagging, topic clustering and instant local search inside the browser extension. Semantic search runs server-side, so it comes with the MCP endpoint, alongside unlimited bookmarks and cloud sync.

Is my bookmark data sent to Anthropic?

When Claude uses the connector, the matching bookmark content is returned to Claude through Anthropic, under its privacy policy. Disconnect OAuth access from Claude when no longer needed. For an older personal-URL connection, rotating the token in the extension invalidates that private URL. These are separate credentials.

Can Claude Desktop modify or delete my bookmarks?

No, it can't modify or delete anything in your library. Claude Desktop can search and retrieve, and since the May 2026 update it can also create new bookmarks with the save_bookmark tool. So it can add saves, but it can't change or remove what is already there.

What if the connector shows as disconnected?

Complete OAuth sign-in, check that Claude and the extension use the same account email, and confirm Pro is active and cloud sync has finished. Reconnect from Claude if needed. Existing personal-URL connections still work if their token has not been rotated.
