Connect Claude
Add Alpha as a remote MCP server and complete OAuth in Alpha.
Add the Alpha server
Use https://mcp.openantares.com/mcp as the server URL. Name the connection Alpha or Antares Knowledge.
Sign in to Alpha
Claude opens the Alpha authorization screen. Sign in with the account whose vault access you want the connector to use.
Troubleshooting
The redirect URI was rejected
Alpha only accepts redirect URIs from approved MCP clients. Use Claude’s built-in connector flow. For the Slack MCP feature, the exact callback is https://oauth2.slack.com/external/auth/callback.
The wrong vault was selected
Ask the client to call list_vaults and then pass the exact vault name or ID to the next tool. Do not continue with an inferred client name when several vaults are plausible.
A write action was refused
The approving person needs editor or admin permission in the target vault. Reconnecting does not upgrade their Alpha role.
