Connect ContextBolt to Claude Code via MCP

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 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 this 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.

Configuration file alternative

If you prefer editing config files directly, add this to ~/.claude/settings.json:

{
  "mcpServers": {
    "contextbolt": {
      "command": "npx",
      "args": ["-y", "@contextbolt/mcp-server"],
      "env": {
        "CONTEXTBOLT_TOKEN": "your-token-here"
      }
    }
  }
}

Or for project-level config, create .mcp.json in your project root with the same structure. Project-level config is useful if your team shares a ContextBolt setup.

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.

Setup guide

1. Get your MCP token from ContextBolt

   Open the ContextBolt extension popup in Chrome and click Settings. Under the MCP section, click 'Copy MCP Token'. You need a Pro subscription (£4/month) as MCP is a Pro feature.

2. Add ContextBolt via the CLI

   Open your terminal and run: claude mcp add -e CONTEXTBOLT_TOKEN=your-token-here contextbolt -- npx -y @contextbolt/mcp-server. This registers the server at the user level so it's available in all your projects. Replace your-token-here with the token you copied.

3. Test the connection

   Start a new Claude Code session and ask 'Search my bookmarks for articles about API design'. If the connection is working, Claude will call the ContextBolt MCP tools and return matching bookmarks from your collection.
