This one has been quiet for a while

Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

Available tools 13

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

app

create_app

Create an app entry without deploying files. Reserves the name and sets initial configuration. Supports BYO (Bring Your Own) integrations via proxy secrets — after creation, use set_secret to attach third-party API keys and verify_integration to confirm connectivity. Use deploy_app later to push files.

get_app

Get details of a specific app including URL, capabilities, and version.

update_app

Update app settings (e.g., toggle public/private) without full redeploy.

deploy

deploy_app

Deploy a full-stack web app. Creates or redeploys an app with static files, optional database, file storage, user auth, and RBAC. Supports BYO (Bring Your Own) integrations — after deploy, use set_secret to attach third-party API keys (Stripe, Resend, Neon, etc.) and the app can proxy requests through them securely. Returns a live URL.

deploy_preview

Deploy an ephemeral preview of an app. The preview auto-expires after the specified TTL (default: 1 hour, max: 24 hours). Returns a unique preview URL.

apps

list_apps

List all apps deployed with your API key.

claim

claim_deployment

Claim ownership of an agent-deployed app using its claim code. Transfers the app from the deploying agent to your account.

custom

create_custom_domain

Attach a custom domain to an app. Returns DNS instructions (CNAME + TXT records) for verification. Requires Hobby tier or above.

deployment

get_deployment

Get deployment history and version info for an app. Returns the current version, available rollback versions, and deploy trail entries.

logs

get_logs

Get recent deploy logs and operational events for an app. Includes deploy successes, failures, rollbacks, and errors.

secret

set_secret

Store a BYO (Bring Your Own) proxy secret for an app. Used to attach third-party API keys so the app can proxy requests through AgentBuilders without exposing keys to the client. Common secret names: STRIPE_SECRET_KEY, RESEND_API_KEY, NEON_DATABASE_URL, SENTRY_DSN, POSTHOG_API_KEY, CLERK_SECRET_KEY, OPENAI_API_KEY, GITHUB_TOKEN. Domains are auto-detected from the secret name (e.g., STRIPE_* routes to api.stripe.com). Secret values are never returned in responses. Use verify_integration after setting a secret to confirm connectivity.

verify

verify_integration

Verify a BYO (Bring Your Own) integration is correctly configured for an app. Checks that the proxy secret exists, the target service is reachable, and a lightweight health probe succeeds. Returns structured pass/fail per check. Supported services: stripe, resend, neon, sentry, posthog, clerk, openai, github, supabase.

viewkey

get_viewkey

Get the viewKey for a private app. Users need this to access the app.

AgentBuilders — questions

Answers built from our own checks of this server.

What can AgentBuilders do?

It exposes 13 tools, read directly from the server on our last check. Among them: claim_deployment, create_app, create_custom_domain, deploy_app, deploy_preview, get_app and 7 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is AgentBuilders mostly used for?

Its tools cluster around app and deploy. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is AgentBuilders working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 113 ms. The bar chart above shows every period we have measured.

Is AgentBuilders still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect AgentBuilders?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does AgentBuilders need an API key?

Yes. Every time we knock, AgentBuilders answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is AgentBuilders?

It answers our handshake in 113 ms on average, which is faster than 90% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
