Kite is a no-code Discord bot builder that hosts your bot. Its MCP server lets your AI client build the bot for you: slash commands, event listeners and messages with buttons. It can also edit existing flows, read logs to fix errors, and add ready-made templates like tickets or verification. Changes go live right away, and commands show up in Discord within a minute. It can also read your server through the Discord API, like channels, roles and members. Claude, ChatGPT, Claude Code, Codex and VS Code connect by signing in. You pick which apps the client can access and whether it can make changes. Other clients like Cursor use a Kite API token. Earlier versions of every flow can be restored in Kite.

Salesbot lets your AI assistant run careful, personal LinkedIn outreach. Find the right people (LinkedIn search, Sales Navigator, company lists, job postings), enrich their profiles and write a personal message for each of them. Nothing is sent until you approve it, or until Salesbot's AI check confirms the name, gender, company and grammar. Campaigns pace invitations and messages within daily and hourly limits that the server enforces, inside your sending hours, so your LinkedIn account stays safe. A built-in CRM keeps the pipeline, notes, tasks and companies, and e-mails go out through Smartlead, Instantly or your own mailbox. Sign in with your Salesbot account (OAuth) or use an API key. Built for a few well-chosen people at a time, not bulk blasting.
