Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Hashnode account to Claude via Composio Connect, enabling it to list your most recent Hashnode articles, check if 'devjournal.com' domain is available, fetch popular tags for trending topics, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Hashnode account

Back in Claude, ask it to connect to Hashnode or give it any Hashnode-related task.

For example, ask Claude to:

  • "List your most recent Hashnode articles"
  • "Check if 'devjournal.com' domain is available"
  • "Fetch popular tags for trending topics"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Hashnode account is ready to use.

What is the Hashnode Claude Connector, and what's possible with it?

The Hashnode MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Hashnode account. It provides structured and secure access to your blog and developer publication data, so your agent can fetch articles, manage publication invites, reply to comments, and explore tags or user details on your behalf.

  • Fetch and analyze articles: Let your agent retrieve single articles or lists of posts from your publications, making it easy to summarize, review, or manage your content.
  • Publication invite handling: Effortlessly accept publication invitations or view all your pending invites, streamlining the process of joining new developer teams or publications.
  • Interact with comments and replies: Have your agent add replies to existing comments, enabling automated engagement and conversation management on your posts.
  • Tag discovery and trend tracking: Easily fetch popular tags so your agent can suggest relevant topics, optimize your writing focus, or help you follow industry trends.
  • User and publication insights: Retrieve detailed profile information for any user or publication, giving your agent the context needed for personalized recommendations and content actions.

Troubleshooting

1. Why does Claude not use the Composio connector for Hashnode?

The connector can show as connected, but Claude must use it in each Hashnode conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Hashnode again.

2. Why does Claude show an MCP server error before Hashnode connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Hashnode.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Hashnode.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Hashnode authorization link not work?

The Composio connector is one server. Your Hashnode account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Hashnode connection.
  • Composio creates a fresh Hashnode authorization link.
  • Open that link in your browser and finish the Hashnode sign-in.

4. Why do Hashnode actions fail after they worked before?

The Hashnode connection can expire or lose permission.

  • Ask Claude to inspect the Hashnode connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Hashnode account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Hashnode.
  • If the action still fails with a permission error, check that the connected account has that permission in Hashnode itself.

5. How do I switch to a different Hashnode account?

Claude can manage the Hashnode connection for you.

  • Ask Claude to disconnect or delete the current Hashnode account.
  • Ask Claude to connect Hashnode again.
  • Open the new Composio authorization link for Hashnode.
  • Sign in with the other Hashnode account in the browser.
  • After the account connects, ask Claude to retry the Hashnode task.

6. Why is my Hashnode connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Hashnode connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click and click Clear cache.
  • If Hashnode tools still do not appear, click , disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Hashnode.

FAQ

Frequently asked questions

With a standalone Hashnode MCP server, the agents and LLMs can only access a fixed set of Hashnode tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Hashnode and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Hashnode tools.

Yes, absolutely. You can configure which Hashnode scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Hashnode data and credentials are handled as safely as possible.
