Getting started
Learn March's product model and the path from change to result.
What March does
March starts with a change: for example, a merged GitHub pull request or an event submitted by an MCP client. It investigates what that change affects in your company context, then produces an evidence-backed result.
An investigation is the asynchronous run that loads the change, checks the configured context, records evidence, and concludes with a decision. The configured context is either a local directory of company documents or one or more public web roots. See Sources and configuration.
The shortest path
- Sign in to March with an invited, allowlisted Netlify Identity account.
- On the Inbox, paste a GitHub pull request URL into Check a change and
choose Check. Or connect an MCP client and call
submit_event. - March stores the investigation as
pending, starts background work, and changes it torunningwhile it investigates. - Open the change from the Inbox. A completed investigation shows what March Understood, Checked, Found, and Concluded, followed by its outcome and supporting evidence.
March also supports an automatic GitHub path: a signed webhook starts an investigation when a pull request is merged. See GitHub.
What you get back
The result is one of these exact decisions:
propose_action: March found consequences and proposes actions or updates.no_action: the evidence supports leaving the checked surfaces as they are.escalate: March cannot safely decide and gives a question and reason for a person to resolve.
Failures inside the investigation run are stored as a completed escalate
result: unreachable model providers after retries use model_unavailable, and
other run failures, incomplete conclusions, or step-budget exhaustion use
insufficient_evidence. An investigation is failed only when a pre-result
failure prevents an outcome (for example, missing stored input, source/context
loading, storage, or a trigger path that calls store.fail). A pending or
running investigation whose last update (updatedAt) is older than 20
minutes is treated as failed with Investigation timed out.
