AI agents use Compoid_upload_file to create or modify resources in Compoid. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call Compoid_upload_file repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Compoid.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Upload a file to the Compoid MCP server. Accepts a data URI (data:<mime>;base64,<data>). Returns the server-side path to use as file_upload in Compoid_create_record or Compoid_update_record.. It is categorised as a Write tool in the Compoid MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Compoid MCP server in PolicyLayer and add a rule for Compoid_upload_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 Compoid. Nothing to install.
Compoid_upload_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 Compoid_upload_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 Compoid_upload_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.
Compoid_upload_file is provided by the Compoid MCP server (compoid/compoid-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
