Cursor governance guidance

About Cursor

Cursor is an AI code editor that helps developers write, change and review software using AI from several providers. Its reach grows in steps. It starts by completing code as people type, moves on to agents that read the codebase, edit many files and run commands on a developer’s machine, and extends to agents that work in the vendor’s cloud and review or fix pull requests without anyone watching each step. Good governance lets an organisation take up each step with confidence and get the productivity gain without losing sight of its code, credentials or systems.

Where governance makes the difference

• Code leaving under the wrong arrangements. Source code, configuration and secrets travel to AI providers as context. Without agreed settings, approved models and managed accounts, some of that work can end up outside the data protections the organisation chose.
• Agents following instructions they read. An agent that reads files, web pages and tool output while it can run commands can be steered by content written to influence it, leading to changes or commands nobody intended.
• Cloud agents working beyond their purpose. Agents that work unattended with repository access, credentials and network reach can make changes at volume. Without a clear owner and agreed limits, their reach can grow faster than oversight.

For the executive team

The gain depends on settling the data question early

Cursor sends code to AI providers to do its work. The organisation decides which providers and arrangements are acceptable, whether staff may bring their own accounts and which code is too sensitive to share. Making those decisions before a wide rollout is what lets engineering move quickly without surprises later.

Agents that act need owners and limits

Cursor’s agents can change code, run commands and open changes for review. Each team or repository using them in earnest needs a named person accountable for how they are used, with agreed limits on what the agents may reach and which changes need a person to approve them.

Human review stays the safeguard for what ships

AI-written code can move into production quickly. The organisation’s existing review and release practices need to keep pace, so that every change reaching customers has been checked by someone who understands it.

Oversight needs to keep pace with change

New AI options, new connections to other tools and new ways of running agents arrive regularly. The setup approved at launch will not be the one in use a few months later, so oversight works best as an ongoing practice rather than a one-off approval.

Questions worth putting to management

• Who is accountable for Cursor and for each team running agents with it?
• Which AI providers may receive the organisation’s code, and how is that enforced?
• Is all Cursor use on managed company accounts, or is some on personal accounts?
• What can agents do without a person approving each step, and who decided that?
• How would the organisation know if an agent did something it should not have?
• If a customer, auditor or insurer asked how AI-assisted development is governed, what would be shown to them?

What good reporting looks like

Expect regular reporting on how widely Cursor and its agents are used, the main risks and how they are changing, spend against budget, any incidents or near misses and the significant decisions taken, with who made them and why.

How Aicura can help

• One register showing Cursor, the teams and agents using it and who is accountable for each, with ownership history kept.
• Spend tracked as contracted, as billed by the vendor and as estimated from observed use, so cost stays in view as adoption grows.
• Board reports drafted from the governance record, covering use, risks, incidents and the decisions taken.

For risk, compliance and assurance

Set where Cursor sits in the risk appetite

Decide which code and repositories Cursor may work with and which must stay out of its reach. Repositories holding regulated logic, security controls or customer data in fixtures and test sets may warrant tighter rules than the rest. Decide which kinds of change agents may make on their own and which always need a person to approve them.

Assess the editor and the agents separately

Assess Cursor as an assistant on developers’ machines, covering the code it sees, the providers it sends that code to and how output is reviewed. Assess agents on their own terms, covering the repositories, credentials and network access they hold, the actions they can take unattended and who reviews their changes.

Reassess when anything changes

A new AI model, a new connection to an outside tool, a change to what agents may run without approval or a move to cloud agents each shifts Cursor away from what was assessed. Each needs to trigger a fresh assessment rather than wait for the annual cycle.

Make the data decisions explicitly

Decide whether the vendor’s setting that keeps code out of training and provider retention is enforced for everyone, and confirm which models it covers. Some models carry different retention terms and need deliberate approval. Decide whether staff may connect their own provider keys, since that work then falls under the provider’s own terms rather than the vendor’s arrangements. Decide whether cloud agents may hold copies of repositories while they work and check how the vendor describes that storage.

Confirm which protections apply

Check which accounts carry the organisation’s agreed settings and data commitments. Work done in Cursor on personal accounts sits outside those arrangements, so find that use and bring it onto managed accounts. Obtain the vendor’s assurance reports and subprocessor list through its trust centre and review them on a cycle.

Govern changes to AI choices

The vendor adds and retires AI models over time. Decide whether newly offered models are available by default or only once approved, and record the organisation’s position on each model in use.

Set limits and name who acts

Agree the limits that matter, such as spend per person or team, unusual agent activity, commands outside what was approved or a sudden change in use, and name the person who acts when one is crossed.

Be ready to show governance to others

• Policy. Maintain an AI use policy that covers Cursor specifically, including which code may be shared, which models and accounts are approved, what agents may do unattended and how AI-written changes are reviewed. Tie each commitment to the control that carries it out.
• Accountability. Record decisions about providers, models and agent permissions with their reasons when they are made. Have team owners confirm periodically that their use still matches what was approved.
• Operating evidence. Keep records that controls actually ran, such as enforced settings, administrative changes, approved model lists and reviewed changes.
• External scrutiny. Prepare for internal and external audit, certification against standards such as ISO/IEC 42001, regulator enquiries and insurer questions about AI in software development.
• Customers and partners. Customers increasingly ask whether their data or code is shared with AI providers. Have the Cursor answer ready and supported by evidence.
• Incidents. Be able to reconstruct which agent, which repository, which model, which commands and which controls were in place at the time.

How Aicura can help

• Risk and impact assessments against recognised frameworks that run again whenever models, connections or agent permissions change, feeding a managed set of risks and controls that can mirror to the GRC platform.
• The organisation’s own position on each model Cursor offers held alongside what the provider says, with notice when a model changes or is retired and the response recorded.
• Vendor records for Anysphere with due diligence, contracts, a relationship owner and review dates.
• Every decision and control action kept as evidence that can be verified without relying on the organisation’s word.

For technology and security

Discover every form Cursor takes

Inventory the desktop editor, the command-line tool, cloud agents, self-hosted agent workers and automated pull request review. Record which repositories each touches, which models and outside tools it uses and which credentials agents hold. Look for Cursor on managed devices and in repositories that carry its configuration, including use on personal accounts.

Lock in managed accounts and settings

Use device management to restrict sign-in to the organisation’s own team, keep the editor on supported versions and limit which extensions may be installed. Enforce the data protection setting at team level so members cannot turn it off, and restrict the models people may choose to the approved list.

Keep sensitive code out of reach

Exclude sensitive files and repositories from AI context. The vendor notes that its ignore files are not a security boundary, so protect the most sensitive material with access controls on the repositories and machines themselves.

Bring change points under change control

Model access, repository exclusions and several team settings can be changed through the vendor’s admin API. Hooks and rules sit in repositories, and command and tool allowlists can be distributed as files through device management. Hold these as code and run a preflight check on every change, so a new model, tool, hook or permission is checked against agreed rules before it goes live.

Control which tools agents can call

Limit which MCP servers and tools agents may use to an approved list, and decide which commands may run without a person approving them. Treat the command allowlist as an aid rather than a boundary and keep auto-run settings conservative for repositories that matter.

Use hooks as controls inside the agent loop

Cursor hooks can inspect and block a prompt before it is sent, a file before it is read, a shell command before it runs and an outside tool call before it is made. Distribute hooks centrally, use them to redact secrets and stop disallowed commands and set them to fail closed where the risk warrants it.

Use the network for what a gateway cannot read

Requests from the editor go to the vendor’s backend as the vendor’s own application traffic, even when staff use their own provider keys, and the vendor’s servers then call the AI providers. A gateway or proxy on that leg can allow, block, log and meter the traffic rather than read or alter prompts, so rely on hooks, enforced settings and contract for content control. Use the network edge to allow only the vendor’s documented domains for managed teams and steer people away from AI tools outside the approved setup. For cloud agents, restrict outbound access to an allowlist and give them short-lived credentials scoped to the work.

Feed everything Cursor exposes into monitoring

Stream the audit log of administrative changes into monitoring. Bring in the vendor’s OpenTelemetry export of token use, tool calls, cost and cloud agent activity, decide deliberately whether conversation content is exported and pull usage and spend through the admin API. Apply the limits risk has agreed and set responses from alerting the owner to removing access.

Test the agent controls against the live setup

Check on a schedule that hooks, allowlists and network limits hold, using test repositories that carry instructions written to steer an agent. Run the checks again whenever the editor, the hooks or the approved models change.

How Aicura can help

• Discovery of Cursor from device telemetry and code repositories, with each finding proposed for a person to add, link or dismiss, and a register entry recording the models, tools and identities behind it.
• Preflight checks in the pipeline that holds Cursor’s hooks, rules and model and tool settings, checked against the organisation’s versioned rules before a change goes live.
• An OpenTelemetry collector inside the network for Cursor’s telemetry and audit records, flagging tool calls nobody declared and holding readings against agreed limits.
• Budgets and responses when a limit is crossed, from notifying the owner to re-scoping an agent or opening an incident.

Getting lasting value from Cursor

Cursor pays off when it is governed as an ongoing practice rather than approved once at rollout. Three things matter whatever the role. The first is knowing every form of Cursor in use, every agent and who is accountable for each. The second is keeping data settings, approved models and agent limits in step with a product and an engineering practice that both keep moving. The third is being able to show, at any time, how decisions were made and that controls held. Organisations that get these right can extend Cursor’s agents further and faster, with confidence rather than caution.
