WHAT IT DOES

What updateNamespace does on SourceSync Ai MCP Server

AI agents use updateNamespace to create or update resources in SourceSync Ai MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SourceSync Ai MCP Server environment.

WHY IT NEEDS A POLICY

Why updateNamespace needs a policy

The tool modifies namespace settings through configuration parameters. While this is a write operation (it changes data state), it is reversible since configuration updates can be undone by updating again with previous values. This is distinct from the deleteNamespace sibling tool which is destructive.

From the tool's definition Tool description states it 'Updates an existing namespace with the provided configuration parameters.' This is a reversible modification operation that changes namespace configuration rather than destructive deletion.

Verdict

updateNamespace Rate-limited

updateNamespace 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.
