Authentication
Syntaxia supports two authentication paths:- OAuth 2.1 (recommended for Claude.ai web). The client registers itself, you approve consent in Syntaxia, and the access token is issued and stored automatically. Nothing to copy or paste.
- Bearer token (Claude Desktop, Claude Code, Cursor, VS Code). You generate a token under Settings → Integrations and put it in the client’s config.
Sign in to Syntaxia
Generate a token at Settings → Integrations, or initiate an OAuth flow from the Claude.ai connector dialog.
Client setup
Tabs are organized from easiest to most-control. The endpoint is the same for all clients:https://app.syntaxia.com/mcp.

Claude.ai uses OAuth 2.1 with Dynamic Client Registration. You don’t need to generate or paste a token.To switch organizations, click Revoke on the connector card in Claude.ai, then re-add it and pick the other organization on the consent screen.
