Saves a file provided directly by the AI agent into the workspace. Use this to save generated images, PDFs, DOCX, or text files without needing an external URL download. Binary files MUST be provided as base64 encoded strings.
AI agents use save_shared_file to create or update resources in Openclaw Syncralis — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Openclaw Syncralis environment.
The tool creates or modifies files in the workspace by accepting binary or text data and persisting it. This is reversible (files can be deleted), so it qualifies as Write rather than Destructive.
From the tool's definition Tool description states it 'Saves a file provided directly by the AI agent into the workspace', which creates files in a persistent storage location. This is a write operation (create/modify data reversibly).
Attacks that exploit this kind of access
Saves a file provided directly by the AI agent into the workspace. Use this to save generated images, PDFs, DOCX, or text files without needing an external URL download. Binary files MUST be provided as base64 encoded strings. It is categorised as a Write tool in the Openclaw Syncralis MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Openclaw Syncralis MCP server in PolicyLayer and add a rule for save_shared_file: 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 Openclaw Syncralis. Nothing to install.
save_shared_file is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the save_shared_file rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for save_shared_file. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
save_shared_file is provided by the Openclaw Syncralis MCP server (pslkk/openclaw-syncralis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
