PR opens: export access to all users

CONFLICT WITH APPROVED RULE

Permission drift is easy to miss and expensive to fix.

A guest user suddenly sees billing.
An export endpoint becomes available to the wrong role.
An admin-only action loses its restriction.
A support user gains access to internal settings.

These changes can slip through review because the code still works. The risk is in who can now do what.

Mo catches pull requests that break approved permission rules before they merge.

Common permission changes teams want to catch

Role-based access

Keep admin, manager, member, guest, and internal roles aligned with approved access rules.

Exports and downloads

Flag when CSV exports, reports, or sensitive downloads are opened to the wrong users.

Billing and account settings

Catch changes that expose billing data, payment actions, or account controls to unauthorized roles.

Internal tools and ops screens

Protect support, ops, and internal-only interfaces from accidental exposure.

Sensitive actions

Catch changes to delete actions, approval flows, and privileged operations that should stay restricted.

What this protects against

What usually happens

A reviewer checks the code.

The logic compiles.

Tests pass.

Nobody notices the access rule changed.

What Mo adds

Mo checks the pull request against approved permission rules.

If access is wider than approved, the pull request is flagged before merge.

Examples of approved permission rules

Only admins can export users

Guest users cannot access billing settings

Support users can view accounts but cannot delete them

Only finance can issue refunds

Internal notes are visible only to staff

Members cannot change organization-wide settings

Only account owners can cancel subscriptions

Audit logs are never visible to guests

API keys can only be created by admins

Why this matters now

As teams ship faster, permission changes can be buried inside ordinary feature work. A single pull request can quietly widen access in ways nobody intended. Mo adds a focused check for one of the easiest mistakes to miss and one of the worst to discover late.

How it works

Step 01

Approve a permission rule in Slack

Use Slack to approve a rule like "Only admins can export users" or "Guest users cannot access billing settings."

Step 02

Mo watches pull requests

Mo watches pull requests in GitHub or GitLab automatically after connecting.

Step 03

Flag risky access changes

If the code breaks the approved rule, Mo flags it before merge.

Teams can also upload documents with permission rules and approve what should be enforced.

For teams handling sensitive product areas

B2B SaaS

Protect admin controls, exports, and account-level settings.

Keep role-based access rules intact across feature work and refactors.

Marketplaces & ops tools

Protect internal tools, staff actions, and restricted flows.

Prevent accidental exposure of ops dashboards, admin views, or privileged actions.

Compliance-sensitive products

Protect access to customer data, finance actions, and restricted functionality.

Enforce the access boundaries your compliance or legal team requires before any PR merges.
