Official vs Custom MCP Servers
auxilia distinguishes two categories of MCP servers: official (pre-configured in the catalog) and custom (user-registered by URL).
Official MCP servers
Official servers are seeded into the database with their URL, icon, and authentication type. They appear under an Official section on the MCP Servers page with an Install button.
| Server | Auth | OAuth style |
|---|---|---|
| Notion | OAuth 2.0 | DCR |
| Atlassian | OAuth 2.0 | DCR |
| Linear | OAuth 2.0 | DCR |
| Sentry | OAuth 2.0 | DCR |
| Stripe | OAuth 2.0 | DCR |
| Canva | OAuth 2.0 | DCR |
| Intercom | OAuth 2.0 | DCR |
| DeepWiki | None | — |
| Supabase | OAuth 2.0 | DCR |
| Amplitude | OAuth 2.0 | DCR |
| GitHub | OAuth 2.0 | Static credentials |
| HubSpot | OAuth 2.0 | Static credentials |
| BigQuery | OAuth 2.0 | Static credentials |
| Slack | OAuth 2.0 | DCR |
Installing an official server creates a workspace MCP server entry pointing at the correct URL with the correct auth type.
DCR servers
Servers that support Dynamic Client Registration handle OAuth automatically. When a user clicks Connect, auxilia registers itself as an OAuth client on the fly — no client ID or secret needed.
Static-credential servers
Some providers (GitHub, HubSpot, BigQuery, …) require you to register an OAuth application yourself in their dashboard and supply the client ID and secret to auxilia at install time.
See the step-by-step guides:
Custom MCP servers
You can add any remote MCP server by URL. Click Add MCP Server and fill in:
| Field | Required | Description |
|---|---|---|
| URL | yes | MCP endpoint (must support Streamable HTTP) |
| Name | yes | Display name |
| Description | no | Short description shown on the server card |
| Icon URL | no | Icon displayed on the card |
| Auth Type | yes | none, api_key, or oauth2 |
| API key | if api_key | Sent as Authorization: Bearer <key> |
| OAuth creds | if oauth2 (and no DCR) | Client ID + Secret |
When to use a custom server
- Self-hosted MCP servers inside your own infrastructure
- MCP servers not yet in the official catalog
- Static API-key servers (not in the official list)
- Temporary / experimental servers
