Connect Google Antigravity to Tareno to turn exported notes and screenshots from an agent test run into an X post within 280 characters, saved as a draft you approve in Tareno.
Can Google Antigravity help me write an X post from an agent test run?
Yes, once Tareno is registered as an MCP server in Antigravity. It can take the notes and screenshots you export from a session, write a post of up to 280 characters and store it as a draft through Tareno. No client test with Antigravity has been completed on our side, so published guides define the setup. You approve in Tareno.
Teams that let an agent click through their web app end up with something worth showing: a sequence of screenshots that proves the sign-up flow works, or a failure that was caught before a customer saw it. Sharing it on X is a small act of credibility, if the post says what was tested and what was not. Antigravity produces the notes and screenshots inside the Agent Manager, and Tareno turns the ones you choose into a draft. This page follows a small SaaS team through that routine, with the connection steps that published guides describe, and the caution that an agent's test run is evidence of what it tried, not a guarantee.
Example: a SaaS team shares a checked sign-up flow
Imagine a team that asked Antigravity to walk through its new sign-up flow on three screen sizes. The developer exports the run's notes and the four screenshots she wants to show, and uploads the screenshots to the Tareno library. In Antigravity she asks for a post that says what was tested, one thing that broke and was fixed, and what was not tested. Antigravity writes 250 characters, adds a line that mobile Safari was outside the run, and finds the screenshots with list_media. She reads the post, checks that no test account email appears in the images, and saves it with create_drafts before requesting a Wednesday slot.
Step by step
01
Find the raw MCP file
The route that published guides describe runs through the Agent window menu to Manage MCP Servers and its raw config view. Menu names have moved between releases, so match them to the version you have installed.
02
Register the hosted endpoint
Under mcpServers, add Tareno with its hosted address. Current Antigravity docs specify serverUrl for remote servers and also accept url; the legacy httpUrl field is not supported. If nothing appears, compare the entry with the docs for your Antigravity surface and version.
03
Sign in and try a harmless call
Approve the browser prompt, reload the server list and request list_accounts. Seeing your X account proves the link; an empty answer usually means the account is not yet connected inside Tareno.
04
Export the notes and choose the screenshots
Export the run's notes and pick the screenshots that show the flow. Remove images that show real email addresses or tokens before you upload them to the library.
05
Write what was tested and what was not
Ask Antigravity for a post within 280 characters that names the flow, one defect found and what the run did not cover. A test post that lists only successes is marketing.
06
Save, request and approve
Antigravity finds the images with list_media and saves the post through create_drafts. Give a day, a time and an IANA time zone, and approve the pending request in the Tareno dashboard.
Prompts to copy
Summarize the run honestly
Read the exported notes from the sign-up flow run and list what was tested, what failed and was fixed, and what the run did not cover, such as browsers or screen sizes. Do not claim more than the notes show, and mark anything you inferred.
Check the screenshots
Use Tareno to look up the screenshots named [signup-1 to signup-4] in my media library. Tell me which appears out of order, then list anything visible in the images that I should remove before they are public, such as email addresses or test tokens.
Write the post
Write an X post within 280 characters that says the sign-up flow was run on three screen sizes, names the one defect that was fixed and states one thing the run did not cover. Use first person plural and no hashtags, and give me the character count.
Save the draft
Use Tareno to confirm the X account [handle] and save the approved text with the four screenshots as a draft. Give me the draft ID and the image order, and wait for my day and time zone before asking for any slot.

What Tareno can read
posts published outside Tareno: no; comments: no; transcripts: no; video download: yes
As configured in Tareno on 2026-10-24. The live rules for your own account come from the get_platform_schema tool.
What X itself documents
A post may include up to 4 photos, 1 animated GIF or 1 video.
The allowed video length depends on the posting account, not on the API plan: 20 minutes and 8 GB by default, 125 minutes and 16 GB with X Premium or verified status. Tareno's configuration for X stops at 140 seconds.
Quote-posting through the API requires an Enterprise plan and is not available on self-serve tiers.
Open the client's MCP server settings. Add Tareno with the HTTPS endpoint below using Streamable HTTP. This requires support for authenticated remote MCP, not just local stdio servers.
Choose OAuth, connect and sign in with your own Tareno account. Check the requested permissions. Refresh the client's tool list after authorization.
Run list_accounts first. Confirm the returned workspace and account IDs before creating a draft. If no accounts appear, connect a social account in Tareno first.

Use the same Tareno account across supported clients. Open the relevant setup guide for authentication, first use, reconnect, and revocation.
It shows what the agent tried and saw, not what every user will meet. Post what the notes support, add one thing the run did not cover, and keep screenshots free of real addresses and tokens.
What if the Tareno tools never appear in Antigravity?
Compare the key names in your raw config with the guides and the Remote MCP setup page, since a wrong key can fail silently. We have not tested every Antigravity version ourselves, so treat that report as a lead.
Why did Tareno ask me to sign in again?
Google's codelab says tokens are not shared between Antigravity surfaces such as the IDE and the command line. Signing in once per surface is expected, and nothing in Tareno needs changing.
Should a test post say what failed?
Yes, and what was not tested. A post that lists one fixed defect and one limit is more believable than one that lists only passes, and it fits in 280 characters if you keep it to those two things.
How many screenshots fit in the post?
Up to four photos on X, according to its API documentation and Tareno's configuration. Pick the four that show the sequence in order, and check each for private data.
Can Antigravity send the post to X itself?
No. Each time request is held in Tareno until you approve it in the dashboard, and from Antigravity you can only see that it is waiting. Nothing leaves for X before that approval.
