See how to connectWhat happens after the send
Schedulers stop at the send. First100 keeps the numbers on every post you publish: reach, replies, reposts, clicks. Not likes. Replies weigh three times a like, because that is what spreads a post.
Your posts are broken into patterns: the hook, a number up front, a question at the end, a link in the body, length, image, time of day. Each is compared with the rest of your own posts. The result is a sentence your agent reads before it writes the next one.
Most reach on X comes from replying early on accounts your audience already follows. The radar reads your watchlist and fresh threads on your topics every morning and ranks them: fresh, bigger author, few replies yet, on topic. It drafts. You post.
Every link in a post becomes a tracked link. Clicks are counted, platform previews and bots ignored, so you see which platform, and which post, actually sends people to your site.

First100, also written FirstHundred or F100, is a go-to-market toolkit for AI agents, delivered through the Model Context Protocol (MCP). Connect it to your agent to discover audiences, publish and schedule posts, find businesses, analyze pages, and send outreach.
Use ChatGPT, Codex, Claude, OpenClaw, Cursor, or another compatible MCP client. ChatGPT and Claude can connect by signing in; other clients use your First100 API key. Our documentation walks you through setup for your agent.
First100 publishes to connected X, LinkedIn, Threads, and Bluesky accounts. Community discovery also searches Reddit, Discord, Facebook, and YouTube; publishing to those platforms is not included.
Your AI agent handles reasoning and writing. First100 supplies the tools to research, publish, schedule, and send. You keep working in your agent, and use your First100 account to manage connections, API keys, usage, and billing.
First100 keeps the numbers on every post you publish and turns them into findings for your own account: which hook types, lengths, formats and posting times get more replies and reach for your audience. Your agent reads those findings before it writes, checks each draft against them, and tracked links show which posts turn into clicks, signups and paying customers. Blog posts start from research on what already ranks and where competitors are weak.
Create an account, choose a plan, connect your social accounts, and generate an API key. Add First100 to your MCP client using the setup instructions in your account. The week trial costs $5 for seven days; your AI provider is billed separately.
