"Feishu - A Collaboration and Messaging Platform" matching MCP connectors:

Dedicated static outbound IPv4 over WireGuard. Free 7-day trial, no card, no sales call. A dedicated static IP is a permanent outbound identity for servers you already run. When a partner API, a bank, or a customer's database requires a fixed source address and your platform egresses from a rotating pool, AnchoredIP leases you dedicated IPv4 out of AS41800 and delivers it over a WireGuard tunnel to machines you already have. Any number of machines sit behind one address, so the allowlist entry your partner made never has to change as you scale. Works as a fixed egress IP for CI runners, Kubernetes, serverless functions and anything else with no stable outbound address of its own. Order and provision entirely through MCP — list plans, order, create a tunnel, receive a working config. No account, no card, no sales call. The free 7-day trial hands out a real IPv4 from the same block paying customers use, so you can prove your partner's allowlist accepts you before paying, and you keep the same address when you move to a paid plan. IPv6: every plan includes an IPv6 /48 delegated to you, with reverse DNS you control. Today it carries traffic between your own tunnels with no NAT in between. Global IPv6 routing is planned — the /48 gets its public announcement the day our upstream carries it, at no change in price and no action on your part.
