For Agents

Deploy, list, update, and delete Google Cloud Functions, plus orchestrate v2 upgrades with traffic redirection and source upload URLs. Useful for serverless deployment automation on GCP.

Quickstart

Get started with Cloud Functions API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"deploy a google cloud function"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Capabilities

What an agent can do with Cloud Functions API API.

Deploy a new Cloud Function from a source archive in Cloud Storage

Generate a signed upload URL for a function source archive

Generate a signed download URL for an existing function source

List all functions in a region with paginated results

Patch a function's runtime configuration, memory, or environment variables

View OpenAPI Document

Google Cloud Functions runs short-lived, event-driven code without server management. The v2 API exposes function lifecycle operations — create, update, delete, list — plus signed download and upload URLs for source archives, and traffic-management endpoints used during version upgrades. Agents can deploy a new function from a source archive, generate a signed upload URL for a build artefact, list every function in a region, and orchestrate the v2 upgrade flow that detaches, redirects traffic, and commits or aborts the upgrade.

Use Cases

Patterns agents use Cloud Functions API API for, with concrete tasks.

★ CI/CD-Driven Function Deployment

CI pipelines call generateUploadUrl to obtain a signed Cloud Storage URL, push the packaged source, and then call create or patch on the function resource referencing that source. The flow takes a few minutes per function and replaces gcloud-only deployment with a fully API-driven path that integrates with non-Google CI tools.

Call POST /v2/{parent}/functions:generateUploadUrl, push the archive to the returned URL, then POST /v2/{parent}/functions with sourceUploadUrl set

Region-Wide Function Inventory

Platform teams use the functions list endpoint to enumerate every Cloud Function in a region, surface runtime versions and memory settings, and flag functions that are running on deprecated runtimes. Pagination via pageToken supports environments with hundreds of functions.

Call GET /v2/{name}/locations to enumerate regions, then GET on the functions collection in each region with a filter on runtime

v1-to-v2 Upgrade Orchestration

Operators upgrading a v1 function to v2 call detachFunction to break the v1 link, redirectFunctionUpgradeTraffic to send traffic to the new version, and commitFunctionUpgrade or abortFunctionUpgrade depending on rollout health. Each step is a long-running operation, so callers poll until completion before moving on.

Call POST /v2/{name}:detachFunction, POST /v2/{name}:redirectFunctionUpgradeTraffic, then POST /v2/{name}:commitFunctionUpgrade once health checks pass

AI Agent Serverless Operator via Jentic

An agent invoked by a developer searches Jentic for the right Cloud Functions operation, deploys a packaged function, and reports the resulting URL. For upgrades, the agent orchestrates the detach, redirect, and commit sequence with health checks between each step. Jentic injects a scoped OAuth token at execution time.

Search Jentic for 'deploy google cloud function', execute against POST /v2/{parent}/functions with the prepared sourceUploadUrl, and return the resulting function URL

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Google Cloud OAuth 2.0 credentials and service account keys are stored encrypted in the Jentic vault. Agents receive short-lived access tokens scoped to cloud-platform — raw service account JSON never enters the agent context.

Intent-based discovery

Agents search Jentic by intent (e.g. 'deploy google cloud function' or 'list cloud functions') and Jentic returns the matching operation with its parameter schema, so the agent can call the right endpoint without reading Discovery docs.

Time to first call

Direct Cloud Functions integration: 1-3 days for OAuth, source-upload flow, and long-running operation polling. Through Jentic: under an hour — search, load schema, execute.

Alternative

Cloud Run Admin API

Container-based serverless runtime that overlaps with Cloud Functions for longer-running workloads

Choose Cloud Functions for short event-driven code; choose Cloud Run when you need a custom container or longer execution time

Complementary

Cloud Build API

Builds the source archive that Cloud Functions deploys

Use Cloud Build to compile and package source; use Cloud Functions to deploy the resulting archive

Complementary

Cloud Tasks API

Schedules HTTP tasks that can target Cloud Functions endpoints

Use Cloud Functions to host the handler; use Cloud Tasks to enqueue work that calls it asynchronously

FAQs

Specific to using Cloud Functions API API through Jentic.

What authentication does the Cloud Functions API use?

The Cloud Functions API uses OAuth 2.0 with the cloud-platform scope. Tokens are issued for a Google service account or end user. Through Jentic, the OAuth credential lives in the Jentic vault and the agent receives a short-lived access token only — the underlying service account JSON never enters agent context.

Can I deploy a Cloud Function from a CI pipeline using this API?

Yes. Call POST /v2/{parent}/functions:generateUploadUrl, push your zipped source to the returned signed URL, then POST /v2/{parent}/functions with sourceUploadUrl set to that URL and the runtime, entry point, and trigger configuration. The deployment runs as a long-running operation.

What are the rate limits for the Cloud Functions API?

Cloud Functions admin-API quotas are published per-method in the Google Cloud console under the Cloud Functions API quota page; typical defaults are several hundred deployment operations per minute per project, with separate per-region concurrency limits on long-running operations.

How do I orchestrate a v1-to-v2 function upgrade through Jentic?

Search Jentic for 'detach google cloud function' and execute the returned operation against POST /v2/{name}:detachFunction. Then call /v2/{name}:redirectFunctionUpgradeTraffic to shift traffic, and finally /v2/{name}:commitFunctionUpgrade once health checks pass — or /v2/{name}:abortFunctionUpgrade to roll back.

Can I update a function's runtime or memory without redeploying source?

Yes. PATCH /v2/{name} with an updateMask that lists the fields to change, such as serviceConfig.availableMemory or buildConfig.runtime. The patch reuses the existing source archive and only rebuilds when source-related fields change.

Is Cloud Functions free?

Cloud Functions includes a monthly free tier of invocations, GB-seconds, and outbound networking; usage beyond that is billed per invocation, per GB-second of execution, and for outbound networking as documented on the Cloud Functions pricing page.
