FAQ
Doppler vs Semgrep: which MCP server should I use?
Pick Doppler when reference-only secret injection. Pick Semgrep when pre-commit sast. Doppler is built for resolve doppler secrets, while Semgrep focuses on run semgrep scans.
Can I run both Doppler and Semgrep together?
Yes. MCP clients run each server as a separate process and surface every server's tools simultaneously, so you can install both and let your agent decide which to call. Be deliberate with auth scopes when stacking servers.
