The Settings page groups configuration into cards: Theme, Security, and Data Management.

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:

  1. Go to Settings → Security
  2. Click Add Pattern
  3. Enter a regex pattern (e.g. sk-[a-zA-Z0-9]{48})
  4. Optionally give it a name
  5. Click Save

Data Management

Export All Data

Export your entire MCP Explorer dataset (connections, models, workflows, settings) to a single encrypted JSON file:

  1. Click Export All Data
  2. Enter an encryption passphrase
  3. Download the .json file

Import Data

Restore from an export file:

  1. Click Import Data
  2. Select the .json file
  3. Enter the passphrase
  4. Confirm — existing data is merged

warning: Importing data merges with your existing data. It does not delete existing entries.
