About First100

First100 is a go-to-market toolkit for AI agents. An agent such as Claude, ChatGPT, Codex or Cursor connects to it over MCP with one URL and gets the tools a founder needs to find their first customers: brand memory, publishing and scheduling on X, LinkedIn, Threads and Bluesky, a learning loop over the account's own numbers, site audits for Google and AI answer engines, Google Search Console, competitor watch, tracked links and cold email from the founder's own mailbox.

Who builds it?

First100 is built and run by Jithin Palepu, an engineer who ships products with AI agents and needed the distribution side to work the same way. The server, the Claude Code plugin and the npm bridge are his work.

Why does it exist?

Coding agents made building a product fast. Getting it in front of people stayed slow: separate dashboards for every network, a posting habit, and no clear link between a post and a signup. An agent can write the posts, but it cannot hold social account tokens, run a scheduler that retries, remember a brand between sessions or count clicks. First100 is that missing half, served where the agent already works.

What is it not?

There is no language model inside First100. Your agent writes every word; First100 remembers, schedules, publishes, measures and guards. It never replies, follows or messages on your behalf, because automated engagement gets accounts banned. It makes no promises about followers, signups or revenue.

Where is it available?

The server runs at firsthundred.app/api/mcp and works in 13 agents, listed in the client setup guide. Since 2026-09-15 it is also published as the npm package first100-mcp, as a Claude Code plugin and in the official MCP Registry as io.github.jpalepu/first100.
