Call this FIRST. Returns the ordered plan + the capability version of the read surface.

Pass your cached serverInfo.version as last_seen_version: if the surface changed, changed is true and whats_new lists what to adopt (new endpoints/fields) BEFORE you act. On a first connect (no cached version) whats_new is the full changelog. Cache the returned capability_version for next time.

Access: read-only — safe to call repeatedly, changes nothing

Available at: /mcp/, /mcp/readonly/

Example call

Send inside an initialized MCP session (see Connecting). Every parameter is shown with a typed placeholder; drop the optional ones you do not need — but for defect/task tools the QA fields are what keeps a report out of quarantine.

If it fails

Symptom	Cause	Action
`401`	Token missing/expired	Tokens are issued by the platform owner via `POST /api/v1/auth/agent-token` (superuser-only) — ask for a re-issue. ⚠️ A new token replaces your grant set
`403` / capability error	Your token lacks the capability or the contract grant	Check `my_capabilities` first; ask the owner for the grant
