MCP support
The stdio MCP server provides `guard_text`, `get_run_results`, `list_detectors`, and `restore_placeholders`. `guard_text` runs the Apify Actor; some tools require `APIFY_TOKEN`, while detector listing and local restoration do not.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
