It connects in 2 minutes.

  1. 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.
  2. Add the remote server Run claude mcp add --transport http --scope user bookmarks https://api.contextbolt.app/mcp. The user scope makes it available across projects.
  3. Authenticate in Claude Code Open /mcp in an interactive Claude Code session, select bookmarks, and authenticate. Sign in on the ContextBolt page with your Pro extension account email, enter the email code, and approve the connection.
  4. 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.

Then ask it something real.

“Search my bookmarks for anything about database migrations” While working on a migration, pull in articles and threads you previously saved about migration strategies, rollback patterns, or schema versioning.
“What did I save about React server components?” When building a feature, surface your saved reference material without leaving the terminal. Claude searches semantically, so it finds relevant content even with different wording.
“Find my Reddit saves about Rust error handling” Filter by platform and topic. Useful when you saved a detailed Reddit discussion months ago and want to reference it mid-session.
“I'm debugging a rate limiter. Do I have any saved content about rate limiting patterns?” Use this pattern when you're stuck. Claude searches your bookmarks for anything related to your current problem and brings relevant saves into the conversation.

What it can do in Claude Code.

  • Search bookmarks by meaning during coding sessions
  • Filter by source (web pages, Twitter/X, Reddit, LinkedIn)
  • Pull saved reference material into terminal conversations
  • Access bookmarks from any project directory
  • Combine bookmark search with code analysis in the same session
  • Works alongside other MCP servers you have configured

The longer story.

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.

Claude Code is Anthropic’s command-line interface for Claude. It runs in your terminal, reads your codebase, and can use MCP servers to connect to external tools and data — including your ContextBolt bookmarks.

This integration is particularly useful for developers who save technical content across the web, Twitter/X, Reddit and LinkedIn. Instead of context-switching to your browser to look up that article about caching strategies or that Reddit thread about Kubernetes networking, you can ask Claude Code to search your bookmarks directly from the terminal.

Why ContextBolt MCP matters for coding workflows

Developers hoard bookmarks. Tweets about architectural patterns, Reddit discussions about library trade-offs, LinkedIn posts about scaling lessons. The problem is finding them when you actually need them.

With the Claude Code integration, your saved content becomes part of your coding context. You’re debugging a tricky issue, and you remember saving something relevant last month — just ask Claude Code to find it. The search is semantic, so you describe what you’re looking for in plain language rather than trying to remember exact keywords.

This is especially powerful because Claude Code already understands your codebase. It can combine what it knows about your code with what you’ve saved, making your bookmarks genuinely useful during development rather than collecting dust in a browser sidebar.

Claude Code: configuration file alternative

If you prefer editing config files directly, create or edit .mcp.json in your project root:

{
  "mcpServers": {
    "bookmarks": {
      "type": "http",
      "url": "https://api.contextbolt.app/mcp"
    }
  }
}

Keep "type": "http" for this hosted server. After saving, open /mcp in Claude Code and authenticate bookmarks. Sign in with your Pro extension account email, enter the email code, and approve access. The shared URL has no personal token to replace. Older personal URLs are separate credentials and must stay out of shared files. The full reference, including OAuth and header auth, lives in the Claude Code MCP docs.

Claude Code MCP tips for developers

Search before you search the web: Before reaching for Google or Stack Overflow, check your bookmarks. You’ve already curated high-quality content — use it first.

Combine with code context: Ask Claude Code something like “I’m refactoring the auth module. Do I have any saved content about OAuth best practices?” Claude can connect your bookmarks to the code it’s looking at.

Use platform filters for technical content: Reddit saves tend to be deep technical discussions. Twitter saves tend to be quick tips and opinions. Filtering by platform helps narrow results when you know where you saved something.

Common questions.

What's the difference between project-level and user-level MCP config?

User-level (--scope user) registers the server in your global Claude Code config and makes it available in every project you open. Project-level (the default --scope local, or editing .mcp.json directly) keeps it scoped to one repo, which is useful if you want to commit a shared config for a team. For ContextBolt, user-level is usually right since you want your bookmarks everywhere.

Can I add ContextBolt by editing a config file instead of the CLI?

Yes. In .mcp.json, add {"mcpServers":{"bookmarks":{"type":"http","url":"https://api.contextbolt.app/mcp"}}}. Then open /mcp in Claude Code and authenticate the server. This shared URL is not a secret; your OAuth credentials are stored separately by the client.

Do I need Node.js installed?

No. ContextBolt's MCP server is hosted, not local. Claude Code talks to it over HTTPS, so there is no npx, no Node.js dependency, and no process running on your machine. You only need Claude Code itself.

Can Claude Code modify my bookmarks?

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

How do I check if the server is connected?

Run claude mcp list to see all configured servers and their status. Inside an interactive session, type /mcp to see connection state and which tools each server exposes.
