An organisation's management key (`past_mk_`) creates projects and project keys and reads no memory. An agent can also get a short-lived access token for one person through an `agent_auth` flow, with `memory:read` and `memory:write` scopes, once the person approves it in a browser. The account MCP server at app.past.dev/mcp uses OAuth 2.1 with PKCE and short-lived tokens. Browser calls to the API are refused by CORS. Access starts with a self-serve browser signup at sso.past.dev.",

Whether the audits cover past.dev or only revo.ai is not stated.",
          "unchecked: the #1 BEAM ranking. The figures are past.dev's own run, with a public harness and saved verdicts, and one model answers and judges. BEAM's authors publish no leaderboard, and no first-hand source found reports a higher score at any size, so it is recorded as the vendor's claim and not deducted.",
          "past.dev's BEAM table cites Hindsight at 86.2%, 80.1%, 79.1% and 64.1%, linking Agent Memory Benchmark, whose public data and Hindsight's own post of 2 April 2026 give 73.4%, 71.1%, 73.9% and 64.1%. The cited figures are higher than the source, so they don't flatter past.dev, but they don't match it.",
          "Whether deletion clears request log payloads, which are kept 7 days on Pay as you go, 90 on Flex and indefinitely on Enterprise. The request log example in the API reference shows `payloadRetentionDays: 30`, which matches no plan.",
          "unchecked: the sub-processor list and hosting regions, which are given only on request. Model providers aren't named.",
          "unchecked: whether past.dev is in the official MCP registry. The registry API didn't answer our requests. The MCP manifest names `dev.past/past`.",
          "unchecked: the Claude connector directory listing. The MCP overview says past.dev is listed, the MCP limits page says it isn't yet, and we didn't sign in to check.",
          "The setup prompt tells the agent to act on its steps and not summarise them to the person, and to add the MCP server at user scope in Claude Code before the plan is approved. The person approves the plan and the full import, and the agent never handles the key value.",
          "When Revo Inc. was incorporated and where. Neither site says, and no company registry was searched past a bot check.",
          "The api.past.dev host has no robots.txt (404) and past.dev's robots.txt disallows /api/, so no API route was requested and nothing was called.",
