How to Share AI Database Access With Your Team

You connect Claude to staging. A week later three teammates want “the same thing.”

Easy path: Slack the MCP URL. Everyone pastes it. Usage becomes noise. Someone leaves and the token sits in Slack search forever.

Sharing access is fine. Sharing one immortal production token is not.

Team checklist — on top of endpoint as password, audit logs, staging first:

What you’re actually sharing

On a managed gateway, the endpoint URL is the credential the AI client uses. Your Postgres password stays in the vault. Anyone with the URL can run the same reads that connection allows.

So “sharing access” means sharing read power over a specific database surface — not a friendly bookmark.

Patterns that work

1. One endpoint per environment (minimum)

| Connection name | Who | |-----------------|-----| | staging-ops | Founders, ops, anyone exploring | | prod-replica-readonly | Small set that truly needs current numbers | | analytics-allowlist | Optional: only reporting tables |

Don’t call anything db or Synra. When Usage lights up, you want the name to mean something.

2. Least privilege before the invite

Before you send a URL:

• Staging or replica, not casual primary
• SELECT-only DB user
• Table allowlist — skip full users if they don’t need it
• Known-answer checks once yourself

3. How you deliver the URL

• Password manager shared vault, or org dashboard invite — not a public Slack channel
• If Slack is unavoidable: staging only, then rotate after the week
• Don’t put live tokens in a shared mcp.json in git

4. One owner for Usage in week one

Pick a human. After people start asking questions, they glance at Usage: right credential? weird hours? errors?

If nobody owns the log, you don’t have a shared system — you have a group chat with SQL powers.

Offboarding

When a contractor or teammate leaves:

1. Rotate every endpoint they could have copied
2. Remove org access if you use it
3. Skim Usage around their last active days
4. Update any shared password-manager items

Same urgency as a leaked AWS key — lower drama if you only ever gave them staging.

What not to do

• One production URL in #general
• “Temporary” prod access that becomes permanent
• Five people refining five private definitions of MRR in chat — park that in BI
• Skipping rotation because “they’re trustworthy”

A fifteen-minute team setup

1. Create staging-shared in Synra with SELECT-only + allowlist
2. Verify three known answers
3. Share that URL via password manager to the people who need it
4. Document: “Prod replica only on request; ask ___; rotate if pasted in Slack”
5. Calendar nudge: review Usage in 7 days

Share access. Don’t share one forever-token to production.
