Add this server
The publisher's own command. Not a PlugMCP endpoint.
Host a copy with our keys and logs.
Local command
npx -y @ni-c/[email protected]Credentials from the publisher
- CARDDAV_URL — Root of the CardDAV server, e.g. https://dav.example.net. An address book collection URL also works.
- CARDDAV_USERNAME — Account name. Most hosted services want an app-specific password with it.
- CARDDAV_PASSWORD — Password or app-specific password. Deleted from the environment once read.
- CARDDAV_TOKEN — Bearer token, as an alternative to username and password. Not both.
- CARDDAV_ADDRESSBOOKS — Comma-separated address books this server may touch, by path or final path segment. Default: all of them.
- CARDDAV_MAX_CONTACTS — Contacts a listing returns by default, 1 to 500 (default: 100)
- CARDDAV_READ_ONLY — Set to true to register only the read tools (default: false)
- CARDDAV_INSECURE_TLS — Set to true to accept a self-signed certificate on the configured host only (default: false)
- CARDDAV_ALLOW_PLAINTEXT — Set to true to allow a plain http:// URL to a host that is not loopback, which sends the credentials and every contact unencrypted (default: false)
- CARDDAV_ALLOW_TOOLS — Comma-separated tool names or list_* prefixes to register; 'essential' selects a curated preset (default: all tools)
- CARDDAV_DENY_TOOLS — Comma-separated tool names or list_* prefixes to remove from whatever the allow list left
- ELICITATION — Deliberately unprefixed, and reaches every MCP server in the environment. Set to false to make guarded tools use the two-call token instead of a dialog (default: true)
