The MCP `mempalace_status` tool was returning the server's absolute
`_config.palace_path` to any connected client on both the main
(ChromaDB-backed) path and the sqlite fallback path that runs when
HNSW divergence is detected (#1222). On a single-user local deployment
this is self-disclosure, but in nested-agent or multi-server MCP
topologies the client is a separate trust domain and the absolute
path has no documented client-side use.
Clients that legitimately need the palace path continue to have three
documented channels: the `MEMPALACE_PALACE_PATH` env var (primary) or
its legacy `MEMPAL_PALACE_PATH` alias, the `~/.mempalace/config.json`
file, and the `--palace` CLI flag on most subcommands.
Also corrects stale docs that claimed `mempalace_reconnect` returned a
`palace_path` field; the code returns `{success, message, drawers,
vector_disabled[, vector_disabled_reason]}` on success, plus a no-palace
shape and an exception shape.
- mempalace/mcp_server.py: drop palace_path from tool_status() and
_tool_status_via_sqlite() result dicts
- website/reference/mcp-tools.md: update documented return shapes for
mempalace_status (fix) and mempalace_reconnect (stale-docs correction)
Authored-by: Aaron Salsitz (ICCI LLC, @icciaaron). Claude Code was used
as an authoring and review-orchestration tool, with human-in-the-loop
oversight at every step: Aaron wrote the prompts, reviewed each draft,
called for three independent review passes (drafting / post-rebase
technical / CISA-aligned disclosure-leak), and verified the final patch
behavior before commit.
The regression-guard tests added in #835 were pinned to the old
README shape (tool table + file-reference table). When #897 slimmed
the README and moved that content to the website, three tests
started failing:
TestReadmeToolsExistInCode.test_every_readme_tool_exists_in_tools_dict
TestNoUnlistedTools.test_no_undocumented_tools
TestReadmeDialectNotLossless.test_readme_dialect_line_not_lossless
Changes in this commit:
1. Update the 3 tests to track the new canonical docs surfaces
- Tool list -> website/reference/mcp-tools.md
(tests parse `### \`mempalace_xxx\`` headings instead of
markdown table rows).
- dialect.py lossless disclaimer -> website/reference/modules.md
(any line mentioning dialect.py must not also say "lossless").
2. Fix the website to make "no undocumented tools" true
Add the 10 tools that existed in TOOLS but were missing from
website/reference/mcp-tools.md (create_tunnel, delete_tunnel,
follow_tunnels, list_tunnels, get_drawer, list_drawers,
update_drawer, hook_settings, memories_filed_away, reconnect).
Page header now correctly says "all 29 MCP tools".
3. Align pre-commit ruff pin to match CI (0.4.x)
.pre-commit-config.yaml was pinning ruff v0.9.0, while
.github/workflows/ci.yml installs ruff>=0.4.0,<0.5. The two
formatters produce incompatible output (e.g. v0.9.0 reformats
`assert (x), msg` -> `assert x, (msg)` in a way v0.4.x rejects),
which would cause the pre-commit hook to modify files that CI
then flags as unformatted. Pinning the hook to v0.4.10 keeps
the dev loop and CI in lock-step.
Full suite: 887 passed, 0 failed.
