Upload a local audio/video/text file to Gaudio servers. Handles multipart upload automatically (create → chunk upload → complete). The returned uploadId is valid for 72 hours and can be reused across multiple jobs. Supported formats: WAV, FLAC, MP3, M4A, MOV, MP4, TXT.

AI agents use gaudio_upload_file to create or modify resources in Mcp Developers. 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 gaudio_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 Mcp Developers.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Upload a local audio/video/text file to Gaudio servers. Handles multipart upload automatically (create → chunk upload → complete). The returned uploadId is valid for 72 hours and can be reused across multiple jobs. Supported formats: WAV, FLAC, MP3, M4A, MOV, MP4, TXT.. It is categorised as a Write tool in the Mcp Developers MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Developers MCP server in PolicyLayer and add a rule for gaudio_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 Mcp Developers. Nothing to install.
gaudio_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 gaudio_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 gaudio_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.
gaudio_upload_file is provided by the Mcp Developers MCP server (@gaudiolab/mcp-developers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
