Claude Code

1. Before you start#

Sign in to First100 and choose a plan for the work you want your agent to do. Connect your social accounts before publishing; research does not require a social connection.

Create a key in API key settings and replace f100_your_key in the example. Keep it in your private client configuration.

2. Add First100#

Run this command with your own key. Open Claude Code and use /mcp to inspect the First100 connection.

claude mcp add --transport http first100 https://firsthundred.app/api/mcp \
  --header "Authorization: Bearer f100_your_key"

For app-specific settings and version differences, see the official setup reference.

3. Check the connection#

Use First100 to check my account status and list my connected accounts.

The response should show your actual First100 plan and connected platforms. If tools do not appear, enable First100 for the active conversation and reload your client. If access is rejected, reconnect or update your key. See connection help if the issue continues.

4. Give your agent a goal#

Tell your agent what you built, who it is for, and the outcome you want. Start with research or a draft, then review the next action together.

I’m launching a tool for independent founders. Use First100 to find relevant communities and help me prepare a launch post. Show me the draft before publishing.
