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 Web3 Career account to Claude via Composio Connect, enabling it to find remote Solidity developer roles in Europe, list frontend Web3 jobs using React, show remote Rust blockchain engineer openings, 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.

What is the Web3 Career Claude Connector, and what's possible with it?

The Web3 Career MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Web3 Career account. It provides structured and secure access so your agent can perform Web3 Career operations on your behalf.

Troubleshooting

1. Why does Claude not use the Composio connector for Web3 Career?

The connector can show as connected, but Claude must use it in each Web3 Career conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Web3 Career again.

2. Why does Claude show an MCP server error before Web3 Career connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Web3 Career.

  • 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 Web3 Career.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Web3 Career authorization link not work?

The Composio connector is one server. Your Web3 Career account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Web3 Career connection.
  • Composio creates a fresh Web3 Career authorization link.
  • Open that link in your browser and finish the Web3 Career sign-in.

4. Why do Web3 Career actions fail after they worked before?

The Web3 Career connection can expire or lose permission.

  • Ask Claude to inspect the Web3 Career connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Web3 Career account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Web3 Career.
  • If the action still fails with a permission error, check that the connected account has that permission in Web3 Career itself.

5. How do I switch to a different Web3 Career account?

Claude can manage the Web3 Career connection for you.

  • Ask Claude to disconnect or delete the current Web3 Career account.
  • Ask Claude to connect Web3 Career again.
  • Open the new Composio authorization link for Web3 Career.
  • Sign in with the other Web3 Career account in the browser.
  • After the account connects, ask Claude to retry the Web3 Career task.

6. Why is my Web3 Career connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Web3 Career connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Web3 Career 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 Web3 Career.

FAQ

Frequently asked questions

With a standalone Web3 Career MCP server, the agents and LLMs can only access a fixed set of Web3 Career tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Web3 Career 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 Web3 Career tools.

Yes, absolutely. You can configure which Web3 Career 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 Web3 Career data and credentials are handled as safely as possible.
