WebMCP tools your IDE agent can actually use.

AgentScripts are user-written WebMCP tools. One readable JS file each, scoped per @match, surfaced through Customaise's MCP bridge. Auditable at install. No npm-package boilerplate.

Building MCP tools is easy. Two things are hard: getting them to every client without writing thirty npm packages, and stopping every tool from sitting in scope on every request. AgentScripts handle both. Per-tab scoping means your agent only sees tools for the site it is on. Any MCP client (Cursor, Claude Code, Codex, Antigravity, Kiro, Windsurf) calls them through the Customaise bridge.
