Cursor extends coding agents into deployment monitoring and security review

Thu, 24 Sep 2026 16:01:46 GMT

Cursor released Rollouts and Security Review for Teams and Enterprise plans. Rollouts derives a monitoring plan from a pull-request diff, compares production telemetry with a pre-deploy baseline, and can notify, pause a progressive rollout or prepare a revert pull request under policy. Security Review inspects every pull request in whole-codebase context for injection, authorization errors, secrets, unsafe deserialization, redirects, vulnerable dependencies and insecure configuration. Findings include severity, attack path and a proposed fix.

Cursor cuts agent token costs with smaller prompts and lazy tools

Thu, 24 Sep 2026 16:01:46 GMT

Cursor reports a 7% reduction in user token cost without measured quality loss after cutting about two-thirds of its system prompt, loading low-frequency tool definitions lazily, improving cache boundaries and numbering only every tenth source line. The cache changes reduced cold misses by 20%. Earlier lazy loading of MCP tool definitions cut total tokens by 46.9% in sessions that invoked MCP, while offloading built-in tool definitions reduced static description tokens by 60%. The results come from Cursor's production traffic and A/B tests, not an independent benchmark.

Cursor Projects: a coordinator agent for months-long bodies of work

Fri, 11 Sep 2026 18:31:49 GMT

Cursor shipped Projects in beta to all users: a container for larger bodies of work (a feature, a migration, a full app) that maintains context over months. A Coordinator agent plans work, delegates to parallel implementing agents, and brings finished work back for review; it does not write code itself. A Project runs on its own cloud computer (closing the laptop does not stop it), launching local agents on demand for local testing. Files are synced across all of a project's cloud and local machines, accumulating research, artifacts, codebase knowledge and user preferences — once one agent learns how to test a service, every future agent reuses it. Coordinators can watch Slack channels, run on schedules, or follow PRs and act on signals.

Cursor adds self-hosted machines so cloud agents run on your own infra

Sat, 05 Sep 2026 00:00:21 GMT

Cursor shipped 'Self-hosted machines' (9/2 changelog): tool execution for cloud agents stays entirely on the customer's own network — codebases, build artifacts, and secrets remain on internal infrastructure. Scheduling is a dynamic pool: personal 'My Machines', scalable team pools, and idle-worker hibernation. Cloud agents can run on existing sandboxes — AWS Lambda, Coder, Cloudflare, Daytona, Modal, Namespace, Vercel, E2B — and computer use works on self-hosted Linux and Mac machines.

xAI ships Grok Bot for Enterprise with free Cursor-Enterprise bundling

Sat, 05 Sep 2026 00:00:21 GMT

Grok Bot — xAI's always-on agent product first announced 8/11 ('your team of always-on agents' that 'keep working 24/7') — is now available for enterprises (9/3). 'Grok and Cursor Enterprise customers have free usage for the next two weeks,' and customers 'can invite their whole organization, including people without an existing seat.' xAI paired the launch with an engineering post, 'Designing Grok Bot for a world of persistent agents' (9/3), and a follow-up, 'Setting Grok Bot loose on procurement' (9/4).

OpenAI will cut off Cursor's bundled model access on November 12

Sun, 30 Aug 2026 00:00:20 GMT

OpenAI announced it has notified SpaceX that it intends to wind down the contract providing OpenAI models to Cursor, with a proposed shutoff date of 2026-11-12 — the maximum notice available under the agreement. The reason given: after SpaceX's $60B acquisition of Anysphere closed, OpenAI says it cannot be confident SpaceX will use its technology within the terms of service, citing prior experience with Musk companies (Twitter's ToS breach; Musk admitting under oath that xAI violated OpenAI's ToS). The custom agreement includes a limited change-of-control cancellation window; OpenAI says it will hold the cancellation to the latest possible date while declining to provide future models to Cursor — explicitly naming accountability concerns around the upcoming model Astra. Developers can keep using OpenAI models inside Cursor via their own API key (bring-your-own-key) or the Codex IDE extension.

Cursor turns cloud agents into an always-on event-driven system

Thu, 20 Aug 2026 00:00:23 GMT

Cursor shipped a release that turns cloud agents from on-demand sessions into an always-on system that builds and ships software on its own. The core primitive is Subscriptions: an agent subscribes to an event source such as a PR, a Slack thread, or a schedule, and wakes when something happens. Agents automatically subscribe to the PRs they create and drive them to completion, fixing CI and addressing bot comments; this is cloud-agents-only for now. The same release adds custom modes (any skill pinned as an always-on mode in chat), subagents that each run on their own VM with an isolated project copy and clean context (swarm patterns supported), and /goal, a long-lived objective the agent works toward until complete, pairable with custom modes and /loop. Steering changed too: follow-up messages now queue until the next tool call instead of interrupting the agent mid-action.

Cursor launches Origin, a code hosting platform built for agents

Wed, 19 Aug 2026 00:00:17 GMT

Cursor announced Origin, its own code hosting platform, now rolling out in early beta to all paid plans. Origin is a git hosting service designed for agent scale: create repos and push with git, sync existing repositories from other hosts, and review pull requests natively in Cursor, including agentic code review. Bidirectional GitHub sync mirrors remote refs, merge queues, branch protections, and check runs, so teams can try Origin without giving up GitHub interoperability. Agents can push directly to Origin. Launch partners supply the surrounding toolchain: Vercel for preview deployments, Depot for Docker builds, and Buildkite for CI, wired in through a request-builds tool and MCP servers.

Cursor Builds: pre-warmed environments boot cloud agents up to 3x faster

Sat, 15 Aug 2026 12:26:05 GMT

Cursor shipped Builds: environments prepared hourly in the background so cloud agents boot up to 3x faster. Broken builds never go active; the system falls back to the last good one. A new Builds tab in the dashboard shows logs and SHAs. It becomes the default for all environments on Aug 17 at no extra cost.

SpaceX closes $60B acquisition of Cursor (Anysphere)

Sat, 15 Aug 2026 12:26:05 GMT

Cursor announced the acquisition has officially closed: a $60B all-stock deal first agreed on 2026-06-16. Cursor now has access to 'the largest fleet of GPUs in the world', and Grok 4.6 (shipped Aug 12) is cited as an early product of the partnership. No leadership or org details were disclosed.
