Claude Code

Connect the AstroWay API to Claude Code over MCP. No file editing - it’s all one terminal command.

Prerequisites

Get an API key in the dashboard. For free testing use a sandbox aw_test_* key - it doesn’t spend credits.

Setup

Run one of the commands in your terminal, then restart Claude Code.

Hosted (HTTP): zero install, Bearer-token auth:

terminal

claude mcp add --transport http astroway https://mcp.astroway.info/mcp \
--header "Authorization: Bearer aw_live_YOUR_KEY"

Stdio (npx): local subprocess, env-var auth, offline-ready:

terminal

claude mcp add astroway --env ASTROWAY_API_KEY=aw_live_YOUR_KEY -- npx -y @astroway/mcp

Verify

Tell Claude in chat: “List the AstroWay tools” - or ask it to call a free reference tool, such as fetching the list of zodiac signs. If a result comes back, the connection works.

Troubleshooting

• 401 / invalid key: make sure the key is prefixed aw_live_* or aw_test_* and isn’t revoked. Check it in the dashboard.
• Tools don’t appear: fully restart Claude Code and confirm the server was added (claude mcp list).
• -32602 validation errors (stdio): update the package: npm i @astroway/mcp@latest. Schemas are regenerated from the live spec.
