Upload a media file from a local file path. Avoids context window overflow issues. Maximum size: 10MB.
AI agents use upload_media_from_path to create or update resources in Strapi MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Strapi MCP Server environment.
This tool creates new media assets in the Strapi CMS. While uploads are reversible (deletable via delete operations), they modify the content store and represent a Write-level risk. Severity is medium rather than high because: (1) the 10MB limit constrains blast radius, (2) media uploads typically don't trigger cascading system effects like content type deletion would, and (3) uploaded files can be removed.
From the tool's definition Tool name 'upload_media_from_path' and description 'Upload a media file from a local file path' indicate file creation/addition to the CMS. This is a reversible modification operation (media can be deleted).

PolicyLayer is an MCP gateway — it sits between your AI agents and Strapi MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for upload_media_from_path:
{
"version": "1",
"default": "deny",
"tools": {
"upload_media_from_path": {
"limits": [
{
"counter": "upload_media_from_path_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}upload_media_from_path 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.
