Medium Risk

upload_files

Upload one or more files to EasySend and get a shareable link. No authentication required. Accepts any file type up to 1GB total.

Part of the Easysend MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

easysend-mcp Write Risk 2/5

AI agents use upload_files to create or modify resources in Easysend. 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 upload_files repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Easysend.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the upload_files tool do? +

Upload one or more files to EasySend and get a shareable link. No authentication required. Accepts any file type up to 1GB total.. It is categorised as a Write tool in the Easysend MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on upload_files? +

Add a rule in your Intercept YAML policy under the tools section for upload_files. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Easysend MCP server.

What risk level is upload_files? +

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

Can I rate-limit upload_files? +

Yes. Add a rate_limit block to the upload_files rule in your Intercept 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.

How do I block upload_files completely? +

Set action: deny in the Intercept policy for upload_files. 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.

What MCP server provides upload_files? +

upload_files is provided by the Easysend MCP server (easysend-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
