Overview

The AgentPowers remote MCP server lets you browse, search, and interact with the marketplace directly from claude.ai. No CLI installation required — just add the server URL to your claude.ai settings and start discovering skills in conversation. With OAuth authentication enabled, you can also view your account profile and purchase history directly in claude.ai.

​
Setup

​
Add to claude.ai

  1. Open claude.ai and go to Settings
  2. Navigate to Integrations (or MCP Servers)
  3. Click Add Custom Integration
  4. Enter the server URL:
  1. Save and start a new conversation

​
Authenticate (optional)

To use authenticated tools (profile, purchase history), click Configure on the AgentPowers integration. This opens the AgentPowers login page where you can sign in with your existing account. Once authenticated, claude.ai will include your credentials in all requests automatically.

​
Verify it works

In a new conversation, try:
“Search AgentPowers for productivity skills”
Claude should use the search_marketplace tool and return results from the marketplace.

​
Available tools

The remote MCP server exposes 9 tools:

​
Public tools (no authentication required)

​
Authenticated tools (requires OAuth)

If you call an authenticated tool without being signed in, you’ll get a helpful message asking you to configure the integration first.

​
Example prompts

  • “What categories of skills are available on AgentPowers?”
  • “Show me the details for the code-review skill”
  • “Find security-related skills”
  • “Who is the seller behind this skill?”
  • “Show me my AgentPowers purchases”
  • “What’s my AgentPowers profile?”

​
Authentication

The remote server uses OAuth 2.0 with PKCE (Proof Key for Code Exchange) for secure authentication. When you click Configure on the integration:
  1. claude.ai discovers the OAuth endpoints via /.well-known/oauth-authorization-server
  2. It registers as an OAuth client (one-time, automatic)
  3. You’re redirected to the AgentPowers login page
  4. After signing in, an authorization code is exchanged for access tokens
  5. Tokens are refreshed automatically — you stay signed in
Your access tokens expire after 1 hour and are automatically refreshed.

​
Limitations

The following features require the CLI or Claude Desktop extension:
  • Installation — downloading and installing skills to your local machine
  • Publishing — uploading and managing your own skills
