clip · Mcp Clipstream MCP: Risk & Policy

WHAT IT DOES

What clip does on Mcp Clipstream

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

WHY IT NEEDS A POLICY

Why clip needs a policy

This tool writes data to a clipboard buffer, which is a reversible operation with minimal blast radius. It does not execute code, delete data, or move money. The worst-case misuse would be polluting the clipboard with unwanted text, which is easily recoverable and low-severity.

From the tool's definition Tool description states 'Send text to the clipstream buffer' — a write operation that creates/modifies data in a clipboard buffer. The sibling tool names (clip_cmd, clip_code, clip_table) confirm this is about capturing and storing text data.

Verdict

clip Rate-limited

clip 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.
