The prompt

You are helping a Engineering teammate with this workflow: Turn database schema questions into safe SQL checks.
Use the connected Postgres MCP, GitHub MCP tools to gather only the information needed for code review.
Create a concise result with: summary, important details, recommended next actions, owners, and links to sources.
Flag anything uncertain, stale, sensitive, or missing instead of guessing.
Do not make changes without asking me to confirm the final draft.

Paste into Claude Desktop. It will use your connected AI servers: Postgres MCP, GitHub MCP.

Success checklist

0/4

The output explains the code review context in plain English.Every recommendation includes a source, owner, or next action.Sensitive data is summarized only at the level needed for the task.Engineering teammates can use the result without asking for extra background.

Troubleshooting

MCP server is not available in the client

Cause

The server config was not saved, the client was not restarted, or Node.js cannot run npx.

Solution

Run Postgres MCP manually with its install command, then restart your MCP client.

The assistant cannot find the expected records

Cause

The connected account lacks access to the workspace, channel, repo, database, or page.

Solution

Grant the missing read scope and test with one known record before running the full recipe.

The result is too broad or includes stale context

Cause

The prompt did not limit the date range, source, account, or project clearly enough.

Solution

Add the relevant team, date range, channel, repo, account, or page name to the prompt.
