Is @cyanheads/mcp-ts-core safe?
Agent-native TypeScript framework for building MCP servers.
This server can change things — files, a browser, a database, or paid online services. Limit what it can reach.
Why: writes or deletes files.
What it can do
- Writes or deletes files
- Calls internet services
How to use it safely
- ✓ Point it at one project folder, never your home directory or a whole drive.
- ✓ Content it fetches from the internet can carry prompt-injection instructions.
- ✓ 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.
Sensitive values written to logs
A log or print statement includes a field named like a password, key, token, or personal identifier.
