Description
Dear Authors / Maintainers,
We are researchers from the University of St. Gallen studying how to make Model Context Protocol (MCP) servers safer to run via a sandboxed permission system. As part of our study, we auto generated a permission manifest for your MCP server and would love your feedback on whether it is correct and complete.
The MCP server in question is: Pipedream
Please review the manifest below and let us know:
* Are the permissions and their scopes correct?
* Are any permissions missing?
* Do any permissions need to be runtime-scoped (e.g., a specific project directory) rather than global?
**Proposed manifest (please review)**
```json
{
"description": "Pipedream MCP server (reference implementation). Node.js/Express server exposing SSE, Streamable HTTP, and stdio transports to run Pipedream Connect tools. It authenticates to Pipedream via the SDK, optionally uses OpenAI for embeddings/LLM, and Supabase for app discovery. Intended for local/self-hosted development.",
"permissions": [
"mcp.ac.network.server",
"mcp.ac.network.client",
"mcp.ac.system.env.read"
]
}
```
Please let us know if you have any questions and/or remarks.
In case you want to see the (current) full permission system:
