Which one, for what

Cursor CLI F

Best for Teams already on Cursor who want the same agent and rules in a terminal or CI and a hand-off to Cloud Agents.

Ahead on

  • Security & auth, 46 against 38
  • Transparency & trust, 60 against 54

Also in its favour

  • Free to start without a card

Watch for

No CLI changelog, and versions are dates

Emdash D

Best for Developers who want parallel agents in worktrees, fed from their issue tracker, locally or over SSH.

Ahead on

  • Reliability, 55 against 27
  • Schema & documentation, 55 against 39
  • Agent ergonomics, 55 against 42
  • Payments & pricing, 60 against 25
  • Maintenance & community, 70 against 62

Also in its favour

  • No key needed to call it
  • Open source
  • No incidents deducted, where Cursor CLI loses 5 points for them

Watch for

Telemetry on unless turned off in Settings or with TELEMETRY_ENABLED=false

Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Payments & pricing Emdash +35

Cursor CLI 25

Harness reading of the published rubric. No payment protocol (0). Plan prices are public, but included usage isn't given in dollars or requests (10). Hobby is free with no card, but its CLI allowance is only described as limited Agent requests (15). A person signs in through a browser to use it or to get an API key (0).

Emdash 60

Free self-hosted software with nothing to buy, so 0 for a protocol and 20 each for public pricing, a free tier and onboarding with no sign-up, 60.

Reliability Emdash +28

Cursor CLI 27

Local-package reading. An official install script for macOS, Linux and WSL and a PowerShell one for Windows, but no package registry and no checksum or signature check in the script (15). No public CI or test suite, since the source isn't published (0). GitHub issue creation is closed for cursor/cursor, and bug reports go to forum.cursor.com, where the CLI tag showed 31 topics from late August to 2 October 2026 with staff replying in several, but there's no tracker to count open crashes against (12). Date-based versions (2026.09.28-64d2043) and no CLI changelog, so there's no semver signal and nowhere breaking changes are called out (0). Not 1.0 and not declared stable. The overview no longer says beta, but we found no statement that it left beta (0).

Emdash 55

Local software. Homebrew cask and installers for macOS, Windows and Linux (20). A code-consistency check and release workflows; no test workflow found (10). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Stable tags to v1.2.11, release notes on GitHub (10). Version 1.2.11 (15). 20 + 10 + 0 + 10 + 15 = 55.

Schema & documentation Emdash +16

Cursor CLI 39

Framework reading. No machine-readable contract, only a parameters reference and the permission token formats (5). cursor.com/llms.txt lists the CLI pages with Markdown twins (10). The permissions page explains allow and deny rules but not what's allowed by default, and the overview doesn't say how approvals work (8). Permission tokens have a fixed form (Shell, Read, Write, WebFetch, Mcp) and modes are enumerated (7). Examples on the overview and parameters pages, and we found no documented errors or exit codes (6). No CLI changelog, and versions are dates (3).

Emdash 55

Harness reading. Docs site and a workspace server package (55).

Agent ergonomics Emdash +13

Cursor CLI 42

Framework reading, adapted to a harness driven by a pipeline. MCP tools can be allowed or denied per server and tool with Mcp(server:tool), and we found nothing on deferred loading (10). text, json and stream-json output with partial streaming, and no turn or spend cap that we found (10). No documented error format or exit codes (5). --resume and --continue (12). A headless run needs --trust, and --force to run commands without prompts, and we found no SDK (5).

Emdash 55

Harness reading. Issue intake from Linear, GitHub, Jira and others, diff review, pull requests and CI checks in one place, local or over SSH (55).

Security & auth Cursor CLI +8

Cursor CLI 46

Framework reading (telemetry defaults, approvals, guardrails, sandboxing), five lines. We found no description of what the CLI sends home. Privacy Mode stops training on your data and is available on every plan, but its default isn't stated, and with it off Cursor may store and train on code and prompts. Headless runs use a long-lived API key (8). Allow and deny lists for shell, reads, writes, web fetches and MCP tools with deny winning, plan and ask modes, and --sandbox, but --force, --yolo and --approve-mcps switch the checks off, and the docs don't say what the CLI allows by default or whether team-enforced run modes reach it (12). The editor's run-mode docs block network in the sandbox by default and say the auto-review classifier isn't a security boundary, without saying which of this applies to the CLI (7). Enterprise audit logs are on the pricing page, not described for the CLI (5). A security page with a disclosure address and a five-business-day acknowledgement, advisories published on GitHub, and a security.txt contact, but no bug bounty that we found (14). SOC 2 and ISO 27001 aren't scored on the framework reading.

Emdash 38

Harness reading. Telemetry is described as optional and disabled in Settings or with TELEMETRY_ENABLED=false, which reads as on by default (15 of 30). Worktree per task and remote machines over SSH (10 of 20). No prompt-injection guidance (5). No audit log (5). No security policy file found (3). 15 + 10 + 5 + 5 + 3 = 38.

Maintenance & community Emdash +8

Cursor CLI 62

Version 2026.09.28-64d2043, dated 28 September 2026 (30). Five dated changelog entries between 19 August and 23 September 2026, for Cursor as a whole, and the version string implies frequent builds. Judgement call, since none of the entries is CLI-only (20). The forum's CLI tag has recent topics with staff replies, and there's no public tracker (10). No SDK found (0). No public CI, and an installer without integrity checks (2).

Emdash 70

v1.2.11 on 6 November 2026 (30). v1.2.9, v1.2.10 and v1.2.11 within two weeks (20). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Current installers and Homebrew cask (15). Release workflows, no test CI (5). 30 + 20 + 0 + 15 + 5 = 70.

How the scores have moved

Verdicts

Cursor CLI

Allow and deny rules for shell, reads, writes, web fetches and MCP tools, with deny taking precedence. No CLI changelog, and versions are dates.

Emdash

A mature open-source app for parallel coding agents in Git worktrees, with issue intake from a dozen trackers and remote machines over SSH. Telemetry is on unless you turn it off, and no test workflow was found in the repository.

Before you call either

Cursor CLI

  1. Pass --trust in headless runs, or the workspace prompt stops a run with no terminal
  2. Write deny rules in .cursor/cli.json before using --force. It runs any command they don't match
  3. Don't use --approve-mcps in repositories you didn't write. Two 2025 CLI advisories came through MCP
  4. Set CURSOR_API_KEY in CI. agent login opens a browser
  5. Record agent --version with each run. Versions are dates and there's no CLI changelog to compare against

Emdash

  1. Launch with TELEMETRY_ENABLED=false if you don't want telemetry
  2. Use the SSH mode to keep agents on a remote machine

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
