From 5bfa4b1d803d93b25237dc81bf6ebb2f9489c9fb Mon Sep 17 00:00:00 2001 From: Hongming Wang Date: Mon, 4 May 2026 07:50:26 -0700 Subject: [PATCH] Memory v2 PR-5: 6 new MCP tools wired through the plugin MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Builds on PR-1, PR-2, PR-3, PR-4 (all merged). Adds the agent-facing v2 surface for the memory plugin contract. What ships (all in handlers/mcp_tools_memory_v2.go, no edits to the legacy commit_memory / recall_memory paths): commit_memory_v2 — write to a namespace; default workspace:self search_memory — search across namespaces; default = all readable commit_summary — kind=summary, 30-day default TTL, runtime-overridable list_writable_namespaces — discover what you can write to list_readable_namespaces — discover what you can read from forget_memory — delete by id, only in namespaces you can write to Workspace-server is the security perimeter — every layer the plugin mustn't be trusted with runs here: * SAFE-T1201 redactSecrets BEFORE every plugin write * Server-side ACL re-validation: CanWrite + IntersectReadable run on EVERY request, never trusting client-supplied namespaces (a canvas re-parent between list_writable and commit would otherwise let a stale namespace slip through) * org:* writes audited to activity_logs (SHA256, not plaintext) — matches memories.go:201-221 so the schema stays uniform * Audit failure does NOT block the write (logged + continue) — failing closed would deny org-scope writes whenever activity_logs is unhappy * org:* memories get the [MEMORY id=... scope=ORG ns=...]: prefix on read — preserves the prompt-injection mitigation from memories.go:455-461 Coexistence design: legacy commit_memory + recall_memory still wired to their old code paths in mcp_tools.go. PR-6 will alias them to delegate to these v2 implementations. PR-9 (60 days post-cutover) removes the legacy entries. Wiring: * MCPHandler gains an memv2 field (nil-safe; tools return a clear error when MEMORY_PLUGIN_URL is unset rather than crashing) * WithMemoryV2(plugin, resolver) is the production wiring API main.go calls at boot * withMemoryV2APIs(plugin, resolver) is the test-injectable variant against the memoryPluginAPI / namespaceResolverAPI interfaces Coverage: 100.0% on every new function in mcp_tools_memory_v2.go. Edge cases pinned: * empty/whitespace content → reject before plugin * plugin unconfigured → clear error, no crash * ACL violation → clear error * resolver error → wrapped error * plugin error → wrapped error * malformed expires_at → silently ignored (no exception) * org write audit failure → logged, write proceeds * search namespace intersection drops foreign entries * search with all-foreign namespaces → empty result, plugin not called * search org memories get delimiter wrap, workspace memories do not * forget with explicit + default namespace * forget cross-scope rejected * pickStr / pickStringSlice handle missing keys, wrong types, mixed slices * wrapOrgDelimiter format is exact-match * dispatch wires all 6 tools (no "unknown tool" error) --- workspace-server/internal/handlers/mcp.go | 92 ++ .../internal/handlers/mcp_tools_memory_v2.go | 380 ++++++++ .../handlers/mcp_tools_memory_v2_test.go | 888 ++++++++++++++++++ 3 files changed, 1360 insertions(+) create mode 100644 workspace-server/internal/handlers/mcp_tools_memory_v2.go create mode 100644 workspace-server/internal/handlers/mcp_tools_memory_v2_test.go diff --git a/workspace-server/internal/handlers/mcp.go b/workspace-server/internal/handlers/mcp.go index bc0b9668..9126955f 100644 --- a/workspace-server/internal/handlers/mcp.go +++ b/workspace-server/internal/handlers/mcp.go @@ -83,6 +83,12 @@ type mcpTool struct { type MCPHandler struct { database *sql.DB broadcaster *events.Broadcaster + + // memv2 is the v2 memory plugin wiring (RFC #2728). nil-safe: + // every v2 tool calls memoryV2Available() first and returns a + // clear error rather than crashing when the operator hasn't set + // MEMORY_PLUGIN_URL. + memv2 *memoryV2Deps } // NewMCPHandler wires the handler to db and broadcaster. @@ -217,6 +223,76 @@ var mcpAllTools = []mcpTool{ }, }, }, + + // ───────────────────────────────────────────────────────────────── + // v2 memory tools (RFC #2728).
