Sensitive Data Protection
MCP Explorer detects and masks sensitive values using a combination of heuristics and configurable regex patterns.
Built-in Detection
The following patterns are detected automatically:
- API keys (OpenAI, Anthropic, Azure, AWS, etc.)
- Bearer tokens and JWTs
- Passwords in JSON payloads
- Private key blocks
Custom Patterns
Add your own regex rules to mask additional sensitive data specific to your environment:
- Go to Settings → Security
- Click Add Pattern
- Enter a regex pattern (e.g.
sk-[a-zA-Z0-9]{48}) - Optionally give it a name
- Click Save
Data Management
Export All Data
Export your entire MCP Explorer dataset (connections, models, workflows, settings) to a single encrypted JSON file:
- Click Export All Data
- Enter an encryption passphrase
- Download the
.jsonfile
Import Data
Restore from an export file:
- Click Import Data
- Select the
.jsonfile - Enter the passphrase
- Confirm — existing data is merged
warning: Importing data merges with your existing data. It does not delete existing entries.
