Moltline Recall is an MCP server with 6 tools an agent can call, among them graph_at_time, graph_compact, graph_diff. It answers at https://mcp.moltlinestudio.com/recall over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
A portable knowledge-graph memory you pass in and get back. No database. 4 of 6 free.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
graph_at_time | See the memory as it stood on a given day, optionally faded by age. PREMIUM (license). Relations carrying since and until are filtered to those in force on the date; with a half-life, confidence decays exponentially with age so a two-year-o Inputs: graph, as_of, half_life_days |
graph_compact | Shrink a memory to the part that still earns its place. PREMIUM (license). Ranks entities by how connected they are and how much is recorded about them, keeps anything you name outright, and drops the rest along with the relations that poin Inputs: graph, max_entities, keep |
graph_diff | Say exactly what changed between two versions of a memory. FREE. The audit trail a database gives you for free, without the database. Typical input {"before": {...}, "after": {...}} returns {"entities_added": ["Beta Ltd"], "entities_removed Inputs: before, after |
graph_lint | Find the breaks a memory graph accumulates as it grows. FREE. Relations pointing at entities that do not exist, entities nothing points at, near-duplicate names, and observations that contradict each other on the same entity. Typical input Inputs: graph |
graph_search | Find what the graph knows about something, plus its neighbourhood. FREE. Scores entities by how many query words appear in the name, type and observations, then pulls in whatever is within the requested number of hops - because the useful a Inputs: graph, query, hops, limit |
graph_upsert | Fold new facts into a memory graph and get the whole graph back. FREE. Idempotent by construction: re-adding the same entity, observation or relation changes nothing, so an agent that replays its own history does not end up with a graph ful Inputs: graph, entities, relations |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.moltlinestudio.com/recall. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
