# Adolf kb#70 — cognee-mcp deletion fix. # # Base: official upstream image (do not hand-roll cognee-mcp itself). # Patches exactly two files to fix a real bug: the `forget` MCP tool (the # only deletion-capable tool actually exposed to agents — `delete`, # `delete_dataset`, and `prune` exist in src/server.py but are never # registered with @mcp.tool(), so they're unreachable dead code) never # exposed a `data_id` parameter, and its cognee_client.forget() wrapper # never forwarded one either — even though cognee's own /api/v1/forget # endpoint has always supported single-item deletion via dataset+data_id. # Net effect: agents could delete an entire dataset but never a single # entry/fact. Verified 2026-07-07 by calling the live /api/v1/forget # endpoint directly with data_id — entry-level delete works fine # server-side; the MCP bridge was just never wired up to use it. # # See src/cognee_client.py forget() and src/server.py forget() for the # fix. Both files are full copies of the upstream 0.5.4 source with only # the forget-related code changed (diff against the base image at # /app/src/{cognee_client,server}.py to see the exact delta).
