Deploy to Render
Render supports Git-backed services and prebuilt Docker image services.
This skill covers Git-backed flows:
Blueprint Method - Generate render.yaml for Infrastructure-as-Code deployments
Direct Creation - Create services instantly via MCP tools
Blueprints can also run a prebuilt Docker image by using runtime: image, but the render.yaml still must live in a Git repo.
If there is no Git remote, stop and ask the user to either:
Create/push a Git remote (can be minimal if only the Blueprint is needed), or
Use the Render Dashboard/API to deploy a prebuilt Docker image (MCP cannot create image-backed services).
Prerequisites
When sandboxing blocks the deployment network calls, rerun with sandbox_permissions=require_escalated.
The deployment might take a few minutes. Use appropriate timeout values.
When to Use This Skill
Activate this skill when users want to:
Deploy an application to Render
Create a render.yaml Blueprint file
Set up Render deployment for their project
Host or publish their application on Render's cloud platform
Create databases, cron jobs, or other Render resources
Happy Path (New Users)
Use this short prompt sequence before deep analysis to reduce friction:
Ask whether they want to deploy from a Git repo or a prebuilt Docker image.
Ask whether Render should provision everything the app needs (based on what seems likely from the user's description) or only the app while they bring their own infra. If dependencies are unclear, ask a short follow-up to confirm whether they need a database, workers, cron, or other services.
Then proceed with the appropriate method below.
Choose Your Source Path
Git Repo Path: Required for both Blueprint and Direct Creation. The repo must be pushed to GitHub, GitLab, or Bitbucket.
Prebuilt Docker Image Path: Supported by Render via image-backed services. This is not supported by MCP; use the Dashboard/API. Ask for:
Image URL (registry + tag)
Registry auth (if private)
Service type (web/worker) and port
If the user chooses a Docker image, guide them to the Render Dashboard image deploy flow or ask them to add a Git remote (so you can use a Blueprint with runtime: image).
Choose Your Deployment Method (Git Repo)
Both methods require a Git repository pushed to GitHub, GitLab, or Bitbucket. (If using runtime: image, the repo can be minimal and only contain render.yaml.)
Method
Best For
Pros
Blueprint
Multi-service apps, IaC workflows
Version controlled, reproducible, supports complex setups
Direct Creation
Single services, quick deployments
Instant creation, no render.yaml file needed
Method Selection Heuristic
Use this decision rule by default unless the user requests a specific method. Analyze the codebase first; only ask if deployment intent is unclear (e.g., DB, workers, cron).
Use Direct Creation (MCP) when ALL are true:
Single service (one web app or one static site)
No separate worker/cron services
No attached databases or Key Value
Simple env vars only (no shared env groups)
If this path fits and MCP isn't configured yet, stop and guide MCP setup before proceeding.
Use Blueprint when ANY are true:
Multiple services (web + worker, API + frontend, etc.)
Databases, Redis/Key Value, or other datastores are required
Cron jobs, background workers, or private services
You want reproducible IaC or a render.yaml committed to the repo
Monorepo or multi-env setup that needs consistent configuration
If unsure, ask a quick clarifying question, but default to Blueprint for safety. For a single service, strongly prefer Direct Creation via MCP and guide MCP setup if needed.
Prerequisites Check
When starting a deployment, verify these requirements in order:
1. Confirm Source Path (Git vs Docker)
If using Git-based methods (Blueprint or Direct Creation), the repo must be pushed to GitHub/GitLab/Bitbucket. Blueprints that reference a prebuilt image still require a Git repo with render.yaml.
git remote -v
If no remote exists, stop and ask the user to create/push a remote or switch to Docker image deploy.
2. Check MCP Tools Availability (Preferred for Single-Service)
MCP tools provide the best experience. Check if available by attempting:
list_services()
If MCP tools are available, you can skip CLI installation for most operations.
Linux/macOS: curl -fsSL https://raw.githubusercontent.com/render-oss/cli/main/bin/install.sh | sh
4. MCP Setup (if MCP isn't configured)
If list_services() fails because MCP isn't configured, ask whether they want to set up MCP (preferred) or continue with the CLI fallback. If they choose MCP, ask which AI tool they're using, then provide the matching instructions below. Always use their API key.
If the user is on another AI app, direct them to the Render MCP docs for that tool's setup steps and install method.
Workspace Selection
After MCP is configured, have the user set the active Render workspace with a prompt like:
Set my Render workspace to [WORKSPACE_NAME]
5. Check Authentication (CLI fallback only)
If MCP isn't available, use the CLI instead and verify you can access your account:
# Check if user is logged in (use -o json for non-interactive mode)
render whoami -o json
If render whoami fails or returns empty data, the CLI is not authenticated. The CLI won't always prompt automatically, so explicitly prompt the user to authenticate:
If neither is configured, ask user which method they prefer:
If user needs to switch workspaces, they must do so via Dashboard or CLI (render workspace set).
Once prerequisites are met, proceed with deployment workflow.
Method 1: Blueprint Deployment (Recommended for Complex Apps)
Blueprint Workflow
Step 1: Analyze Codebase
Analyze the codebase to determine framework/runtime, build and start commands, required env vars, datastores, and port binding. Use the detailed checklists in references/codebase-analysis.md.
Step 2: Generate render.yaml
Create a render.yaml Blueprint file following the Blueprint specification.
services:-type:webname:my-appruntime:nodeplan:freebuildCommand:npmcistartCommand:npmstartenvVars:-key:DATABASE_URLfromDatabase:name:postgresproperty:connectionString-key:JWT_SECRETsync:false# User fills in Dashboarddatabases:-name:postgresdatabaseName:myapp_dbplan:free
Service Types:
web: HTTP services, APIs, web applications (publicly accessible)
Open Dashboard: Use the Blueprint deeplink and complete Git OAuth if prompted
Fill secrets: Set env vars marked sync: false
Deploy: Click "Apply" and monitor the deploy
Step 3: Validate Configuration
Validate the render.yaml file to catch errors before deployment. If the CLI is installed, run the commands directly; only prompt the user if the CLI is missing:
If there is no Git remote yet, stop here and guide the user to create a GitHub/GitLab/Bitbucket repo, add it as origin, and push before continuing.
Why this matters: The Dashboard deeplink will read the render.yaml from your repository. If the file isn't merged and pushed, Render won't find the configuration and deployment will fail.
Verify the file is in your remote repository before proceeding to the next step.
Step 5: Generate Deeplink
Get the Git repository URL:
git remote get-url origin
This will return a URL from your Git provider. If the URL is SSH format, convert it to HTTPS:
SSH Format
HTTPS Format
git@github.com:user/repo.git
https://github.com/user/repo
git@gitlab.com:user/repo.git
https://gitlab.com/user/repo
git@bitbucket.org:user/repo.git
https://bitbucket.org/user/repo
Conversion pattern: Replace git@<host>: with https://<host>/ and remove .git suffix.
Format the Dashboard deeplink using the HTTPS repository URL:
CRITICAL: Ensure the user has merged and pushed the render.yaml file to their repository before clicking the deeplink. If the file isn't in the repository, Render cannot read the Blueprint configuration and deployment will fail.
Provide the deeplink to the user with these instructions:
Verify render.yaml is merged - Confirm the file exists in your repository on GitHub/GitLab/Bitbucket
Click the deeplink to open Render Dashboard
Complete Git provider OAuth if prompted
Name the Blueprint (or use default from render.yaml)
Fill in secret environment variables (marked with sync: false)
Review services and databases configuration
Click "Apply" to deploy
The deployment will begin automatically. Users can monitor progress in the Render Dashboard.
Step 7: Verify Deployment
After the user deploys via Dashboard, verify everything is working.
Check deployment status via MCP:
list_deploys(serviceId: "<service-id>", limit: 1)
Look for status: "live" to confirm successful deployment.
Check for runtime errors (wait 2-3 minutes after deploy):
Create the service (web or static) and any required databases or key-value stores. See references/direct-creation.md.
If MCP returns an error about missing Git credentials or repo access, stop and guide the user to connect their Git provider in the Render Dashboard, then retry.
If deployment fails due to network issues (timeouts, DNS errors, connection resets), rerun the deploy with escalated permissions (use sandbox_permissions=require_escalated). The deploy requires escalated network access when sandbox networking blocks outbound requests.
Example guidance to the user:
The deploy needs escalated network access to deploy to Render. I can rerun the command with escalated permissions—want me to proceed?
Optional: If you need deeper diagnostics (metrics/DB checks/error catalog), suggest installing the
render-debug skill. It is not required for the core deploy flow.
