Scalar
Overview

Get started with Scalar Agent

1
Upload an OpenAPI document

Add one spec or many by pasting a URL or uploading directly. Scalar parses and indexes the document for search and execution.

2
Configure an installation

Create an installation, select the APIs and operations it can expose, and configure OAuth, API keys, bearer tokens, or passthrough authentication.

3
Connect your agent

Use the hosted chat at agent.scalar.com, the Agent SDK, or the installation MCP URL from your own runtime or IDE.

Connect with Claude Code#

Create a personal access token under Account → API Keys, then add the installation URL:

claude mcp add \
  YOUR_MCP_SERVER_NAME \
  https://mcp.scalar.com/mcp/YOUR_INSTALL_ID \
  --header "Authorization: YOUR_PERSONAL_ACCESS_TOKEN" \
  --transport http

Keep credentials separate#

Every MCP connection still requires a Scalar personal access token or an approved customer flow. Configure upstream API credentials in Scalar so shared URLs do not expose them.
