Invalid file permissionpermission deniedEACCES
What it means
The MCP server tried to read or write a path or remote resource outside its allowed permissions.
Most common causes
- Filesystem server root does not include the requested path
- Design or Git provider token lacks scope
- Windows path casing or drive mapping mismatch
- Containerized server cannot see host files
Fastest fix
- Confirm the allowed root path
- Open the file directly from the same server process
- Check token scopes
- Use an absolute path
Safe fix
- Grant the smallest directory required
- Prefer read-only scopes for inspection
- Keep write tools behind confirmation
- Document path rules for Windows, WSL, and containers
What not to do
- Do not grant filesystem access to your home directory by default
- Do not add admin scopes to fix a read-only task
- Do not expose secrets directories to agent tools
How to confirm the fix
Run the smallest reproducible command first, then retry the agent task only after authentication, quota, and tool discovery are stable.
