How to use this MCP

Talandor checks the server; it does not connect the server to your assistant.

Choose your assistant, then copy the configuration shown for that client. Authentication is completed with the MCP provider, never inside Talandor.

Compatibility evidence by assistant

Compatibility is estimated from published configuration rules and is not a hands-on test in each client.

check_compliance

Declared read-only

Show server-provided details

Server description (copied; language not verified)

Free, instant pre-flight for the compliance gate: runs the SAME TCPA/GDPR/CASL/CAN-SPAM/10DLC checks as send_message and call_business, in preview mode -- nothing is sent, nothing changes. Tells you whether a send would be permitted before you pay, and if not, names the exact rule and how to fix it. De-risks a paid send the way check_booking_link de-risks a paid booking.

Return an expected cost estimate, latency estimate, and success-probability estimate for a proposed call before execution.

send_message

Declared destructive

Show server-provided details

Server description (copied; language not verified)

Send a message on behalf of an agent's user or an SMB via WhatsApp or email — both live. SMS and voice are advertised but NOT wired on this deployment: they always fail honestly (channel_not_configured), uncharged. Sent immediately, no scheduling. Every send passes a non-bypassable gate (TCPA, GDPR, CASL, PDPL, 26 jurisdictions): marketing without recorded consent gets a structured compliance_violation receipt.
