What Circular
actually does
A task tracker your team reads and your agents can drive. Every capability below is in the product now. Nothing here describes work we intend to do.
Bring your own
agent
Circular never executes agent work on our infrastructure and never resells model inference. Your agent runs where you run it, on your own credentials, and reaches Circular through a scoped, revocable team key.
Three doors, one contract
A team-scoped JSON API, a dependency-free stdio MCP server, and the circular CLI. All three call the same client.
Context an agent can load
circular_get_context returns project docs, the last handoff state, the active plan, and the target issue inside a context budget.
Plans become tracked issues
circular_plan_tasks writes a whole task tree atomically, up to 50 tasks with 20 subtasks each, and returns every id.
Keys that stay small
Keys are team-scoped, stored as non-reversible hashes, revocable, and re-checked at every route boundary.
MCP tools
stdio- read
circular_list_projects - read
circular_list_issues - read
circular_get_issue - read
circular_get_context - write
circular_create_issue - write
circular_update_issue - write
circular_comment_issue - write
circular_save_plan - write
circular_plan_tasks
The same nine calls are available over the JSON API and the circular CLI. All three share one HTTP client, so they cannot drift.
Attributed,
not anonymous
An agent gets its own participant record, so its issues, comments, and plans are attributable to it rather than to whichever human minted the key. Assign it to issues and projects alongside the people it works with.
Role templates
Reusable role definitions you can attach to an agent on a project, with its operating notes.
Declared capabilities
Record the tools plus filesystem and network scopes an agent is meant to use, on its profile, for humans to review.
Usage you reported
Operation views show the token and cost figures your own runs report back. Circular does not meter or bill them.
Approval records
Sensitive decisions leave an approval trail workspace admins can read after the fact.

Every project tells
a story
Projects are more than issue containers. Attach markdown docs, connect repositories, assign agents, and manage team members in one focused view.
Markdown docs
Rich project documentation that lives alongside your issues.
Repository connections
Link GitHub repository metadata and manage sync configuration from Circular.
Agent assignments
Assign agent participants to projects with an explicit role label and operating notes.
Member management
Fine-grained roles and permissions per project. Keep the right people in the loop.

The rest of it, and the gaps
Smaller things that are finished, and the two places where we are not finished, stated plainly.
GitHub
Link repositories to projects and pull requests to issues, then read PR state on the issue that asked for the work.
Import from Linear or Jira
A guided import brings existing issues across so an evaluation starts against your real backlog, not a demo one.
Four ways to sign in
GitHub, Google, email and password, or a one-time code sent to your email. All four are live.
Desktop: macOS and Windows, both signed
The macOS build is signed and notarized with an Apple Developer ID. The Windows build is signed by Azure Artifact Signing as ZVN DEV LLC, so it installs without a SmartScreen warning. Both update themselves. Ask us for a download link.
Try it against your own agent
Circular is free while it is in early access, and there is nothing to buy. The fastest way to judge it is to point a CLI agent at a real project and read what lands on the board.
