Bot403 MCP

An official MCP server that allows AI assistants to automate the setup of Bot403 bot protection for HTML forms. It enables agents to create sites, manage configurations, retrieve statistics, and verify form tokens programmatically, streamlining the integration of invisible bot shields without manual CAPTCHA challenges.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http bot403-mcp https://bot403.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add bot403-mcp --url https://bot403.com/mcp

Cursor
