WHAT IT DOES

What tileset_add_source does on Godot Breakpoint

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

RISK

Why tileset_add_source is rated Medium

The tool modifies an existing TileSet resource file by adding a new atlas source and re-saving it. While the description labels it 'DESTRUCTIVE', the actual operation is a write/update (adding data and overwriting a file), not an irreversible deletion or purge. File overwrites could overwrite prior state, but the primary action is creating/modifying content rather than deleting it.

From the tool's definition 'Add a TileSetAtlasSource (backed by a Texture2D) to a TileSet .tres and re-save' and 'writes a file — gated by confirmation'

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs tileset_add_source safely

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

tileset_add_source Rate-limited

tileset_add_source 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.

How do I enforce a policy on tileset_add_source? +

Register the Godot Breakpoint MCP server in PolicyLayer and add a rule for tileset_add_source: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Godot Breakpoint. Nothing to install.

What risk level is tileset_add_source? +

tileset_add_source is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit tileset_add_source? +
