Is fluxmail safe?
Self-hosted email API with MCP and REST support for Gmail, Outlook, and IMAP/SMTP
This server can change things — files, a browser, a database, or paid online services. Limit what it can reach.
Why: writes or deletes files; queries a database; uses your API keys to call online services.
What it can do
- Writes or deletes files
- Reads files
- Calls internet services
- Queries a database
- Needs API keys or tokens
Tools it offers your AI (1):
- fluxmail
How to use it safely
- ✓ Point it at one project folder, never your home directory or a whole drive.
- ✓ Only give it the folders it needs; files it reads can end up in the AI’s context.
- ✓ Content it fetches from the internet can carry prompt-injection instructions.
- ✓ Give it a read-only database user unless writes are required.
- ✓ Use a key with the smallest permissions available, and never paste a production key into a shared config.
- ✓ Pin the version (below) so an update can't change what it does without you noticing.
Code patterns worth reviewing
Automated pattern matches in the published package. Some are expected for this kind of server, and some may be false positives — they are pointers for review, not confirmed vulnerabilities.
Command injection risk
The agent appears to pass input into a shell or command execution path.
dist/storage/db.js:803
Plaintext HTTP endpoint
A non-localhost endpoint is referenced over plain HTTP instead of HTTPS.
dist/mcp/buildServer.js:38
External content fed into the prompt without isolation
The agent pulls in outside content (web pages, emails, retrieved documents) and adds it to its prompt, with no visible marking of that content as untrusted data.
dist/mcp/buildServer.js:377
Sensitive values written to logs
A log or print statement includes a field named like a password, key, token, or personal identifier.
dist/cli.js:752
