AI requirements management for space systems engineering

Arc is AI requirements management and verification software for fast-moving space systems engineering teams. It replaces requirements spreadsheets, Python scripts, fragile file links and manual verification tracking with a connected programme model that keeps requirements, architecture, systems, tests and evidence in sync.

Arc combines a configurable engineering workspace with AI agents that can help draft requirements, maintain traceability, assess change impact and evaluate programme records. Engineers review proposed changes, control approvals and remain responsible for the programme baseline.

Arc also provides a public REST API for reading programme context and carrying out supported platform actions. Teams can use it to build custom workflows across their delivery, design, test and reporting tools, or give external AI tools controlled access to programme records. The API, Arc’s native AI agents and the Arc MCP server provide workflows for custom clients, platform assistance and compatible AI tools.

Controls
Programme tokens are created in Program → Settings → API with read or write access. Tokens remain bound to the programme and the owner’s current permissions. Write actions require programme edit permission. Changes use actual model and type IDs and expected_head_revision. Apply changes on a working branch, then use the programme’s review and merge workflow to update the baseline.

Connect Arc to the tools your team uses

These examples describe custom workflows built with Arc’s public API and each other tool’s own interface. The team defines the mappings, permissions, triggers and review steps.

Read the programme model and current branch revision, create a working branch, map the intended records and relationships to real type IDs, then preview the change. Inspect the returned diff, graph, impacts and effects before applying it with the expected revision. Create a pull request for the programme’s review process, then close or merge it only under the team’s authority rules. Engineers review the proposed engineering content before baseline merge.

Connect requirements to delivery work

A custom workflow can read Arc requirements and relationship context, map Jira issue keys or GitHub commit and pull-request references into configured item fields, and propose linked record changes on a branch. Jira or GitHub interfaces supply their own data and actions.

Keep design references in context

Use an available CAD, PLM or model-tool interface to obtain element identifiers and revision references, then map them into Arc items and relationships for review. File ownership, model semantics and configuration authority remain defined by the team.

Connect external evidence references

A custom workflow can read requirement context and propose item fields or relationships containing test-report links, result references and configuration identifiers.

Build reports from programme context

Read paginated records and relationships at a chosen branch revision to prepare coverage reports, review packs or dashboards in another tool. The report should retain programme, branch and revision context so readers can identify its source.

Use external AI within a controlled workflow

An authorised external AI tool can analyse permitted Arc reads, identify possible gaps or draft candidate item and relationship changes. Its findings are external analysis. Applying proposals uses the same branch, preview, revision and review controls as other API clients.

Choose your Arc workflow

The REST API is the HTTP contract for custom clients. Arc’s native agents provide assessment and suggestions in the platform, while the MCP server exposes tools to compatible AI clients.
