WHAT IT DOES

What send_photo does on Ncp

AI agents use send_photo to create or update resources in Ncp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ncp environment.

RISK

Why send_photo is rated Medium

This tool writes/sends data to Telegram via bot API. While photo transmission is technically reversible (messages can be deleted), it commits data to an external platform and has side effects that modify state on a remote service. It does not retrieve data (Read), execute arbitrary code (Execute), irreversibly delete data (Destructive), or handle money (Financial). Write is the appropriate category.

From the tool's definition Tool description states 'Send photo via Telegram bot' - this creates/sends data (a photo message) to an external service (Telegram), which is a reversible action.

RECOMMENDED RULE

The rule that runs send_photo safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ncp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For send_photo, this is the rule to start with:

send_photo Rate-limited

send_photo stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
