check-deployment-status

name	check-deployment-status
description	Check deployment status of PRs and commits using continuous-deployment MCP and UCS deployer MCP. Use when user asks "is this deployed", "check deployment", "deployment status", "is PR merged and deployed", "check UP status", "introduced to production", or provides a GitHub PR URL and wants deployment info.

Check Deployment Status

Check whether a PR/commit is deployed to staging and production using the continuous-deployment MCP tools.

Usage

/check-deployment-status <PR-URL>           # Check deployment of a GitHub PR
/check-deployment-status <commit-hash>      # Check deployment of a specific commit
/check-deployment-status <service-name>     # List recent commits and their deployment status

Key Concepts

PR Head Commit != Merge Commit

When a PR is merged via SubmitQueue, the merge commit on main is DIFFERENT from the PR's head commit. The continuous-deployment system tracks the merge commit, not the PR head.

Workflow:

1. Get PR metadata → extract head SHA
2. Use findServiceCommits with search text to find the actual merge commit on main
3. Use getCommitDeploymentStatus with the merge commit hash

UP Deployment Stages

Stage	Meaning
Build created	Binary built from commit
Deployed to staging	Running on staging instances
Soaked	Staging soak period passed
Waited for deployment window	Outside deploy freeze windows
Introduced to production	Fully deployed to production — code is live

"Introduced to production" = fully deployed. Not partial, not in-progress. The commit is running on all production instances.

Deployment Status Values

Status	Meaning
DEPLOYMENT_STATUS_DEPLOYED	Commit is running in this environment
DEPLOYMENT_STATUS_DEPLOYING	Deployment in progress
(empty)	Not deployed to this environment

Step-by-Step Workflow

Step 1: Get PR Metadata

Use mcp__code-mcp__get_github_pull_request_metadata:

org: uber-code
repo: go-code
number: <PR number>

Extract: title, head SHA, merged status, base branch.

Step 2: Find Merge Commit

The PR head SHA won't be found in deployment system. Search for the merge commit:

Use mcp__continuous-deployment__continuousdeployment_findservicecommits:

service_name: <service-name>
filter: { search_text: "<keyword from PR title>", commited_after: "2026-02-25T00:00:00Z" }
offset: 0
limit: 5

The result includes the merge commit hash, serial number, and code review metadata linking back to the PR.

Step 3: Check Deployment Status

Use mcp__continuous-deployment__continuousdeployment_getcommitdeploymentstatus:

hash: <merge-commit-hash>
repository: [e-mail]:go-code
options: { scope: "SCOPE_ALL_SERVICES" }

Returns deployment status per service per environment (staging, production, bits-test-sandbox).

MCP Tools Reference

continuous-deployment MCP

Tool	Purpose
findServiceCommits	Search commits by service name, author, text, date range
getCommitDeploymentStatus	Get deployment status of a commit across all environments
listServiceCommits	List recent commits for a service (with serial-based pagination)
getCommitsInDeployment	List commits in a specific deployment task
listCommitSegments	Get deployment segments for a service
getConfigForService	Get continuous deployment config for a service

code-mcp

Tool	Purpose
get_github_pull_request_metadata	PR status, author, labels, SubmitQueue status
get_github_pull_request_diff	PR diff content
get_github_pull_request_comments	PR comments

UCS deployer MCP

Tool	Purpose
ucsdeployer_status	Rollout status for a specific deployment object
deploystatemanager_read	Read deploy state

Service-Name Only Mode

If only a service name is provided (no PR/commit):

Use mcp__continuous-deployment__continuousdeployment_listservicecommits:

service_name: <service-name>
offset: 0
limit: 5

Then check deployment status for each returned commit using Step 3.

Common Patterns

Stacked PRs

For stacked PRs, each PR may affect different services. Check deployment per-service:

• PRs changing marketing-recommendations/ → check marketing-recommendations service
• PRs changing ads-insights/ → check ads-insights service

Repository URI

For go-code monorepo, always use: [e-mail]:go-code
