[FEATURE] Support non-HTTP/HTTPS ports for database access in Claude Code Web (e.g., MongoDB, PostgreSQL)

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Claude Code currently restricts network access to HTTP/HTTPS ports. This prevents direct connections to databases like MongoDB (27017), PostgreSQL (5432), MySQL (3306), Redis (6379), etc.

When working on backend projects, it's common to need direct database access for:

Running queries to inspect or back up data
Executing migration scripts
Debugging data issues during development

Request: Allow Claude Code to access non-HTTP/HTTPS ports

Proposed Solution

Allow custom ports

Alternative Solutions

_No response_

Priority

Critical - Blocking my work

Feature Category

Claude Code Web

Use Case Example

Running queries to inspect or back up data
Executing migration scripts
Debugging data issues during development

Additional Context

Cursor supports this without issue. Having to work around this limitation (e.g., shelling out to CLI tools like mongosh or psql) adds friction.
