OVERVIEW A portable knowledge-graph memory: the graph is passed in and returned, so nothing of yours is stored on this server — no database, no embedding key, no account. Upsert facts idempotently, search with neighbourhood, diff two versions and lint for breaks; with a licence, time-travel and compact.

KEY CAPABILITIES • graph_upsert — fold entities, observations and relations into a graph; idempotent, so replayed history never duplicates • graph_search — score entities by query words and pull in the neighbourhood within the requested number of hops • graph_diff — exactly what changed between two versions of a memory • graph_lint — dangling relations, orphan entities, near-duplicate names and contradicting observations • Licence: graph_at_time (the memory as it stood on a date, optionally decayed by half-life) + graph_compact (keep the part that still earns its place)

USE CASES • Give an agent a memory it carries between sessions without standing up a database • Record what a session learned as a diff • Reconcile what two agents know

WHO THIS IS FOR Agent builders who want a memory they own and can inspect, in plain JSON.

WHY MOLTLINE • Every tool tested against known answers before release • One All-Access licence ($19/month, settled in cryptocurrency through NOWPayments) unlocks the premium tools on every Moltline server - send it in the X-Moltline-License header • Support: first response <24h, confirmed defects fixed <30 days
