Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

tim_read
tim_write
tim_write_many
tim_search
tim_guard
tim_delta
tim_link

Create an edge (relationship) between two entries.

tim_unlink
tim_trace

Follow an edge chain from a starting entry (BFS traversal).

tim_update
tim_verify

Re-confirm entries as still valid without editing them. Stamps metadata.verified_at — clears the stale annotation on reads and the stale count in tim_health.

tim_delete

Delete an entry (soft: mark irrelevant, hard: tombstone).

tim_delete_batch

Batch hard-delete entries by id (max 100). Skips missing ids.

tim_sync

Sync operations: push staging records, pull from remote, or check status.

tim_suppress

Suppress entries matching a pattern: hidden from tim_search, tim_read, tim_show, tim_section_children, tim_remember, and tim_load_project. Optional TTL (e.g. "24h", "7d").

tim_health

Run health diagnostics: broken links, orphans, FTS integrity, counts, memory coverage and embedding backlog.

tim_stats

Content statistics: entry counts, content size aggregates, length buckets, and breakdown by metadata.kind.

tim_section_children

List direct children of a project section in compact form.

tim_export

Export TIM database to markdown or .hmem SQLite format.

tim_import

Import entries from a .hmem SQLite file. Always call tim_import_manifest first, then tim_import with dryRun:true, then live import, then tim_import_audit. Never use raw SQL for hmem migration.

tim_import_manifest

Read a .hmem file without importing it: format, labels, titles, and node counts.

tim_project_structure

Return one project structure: root, direct sections, duplicate sections, loose direct children, and imported hmem provenance.

tim_find_duplicates

Report-first duplicate detector: scans a project for near-duplicate entries (identical/similar titles or embeddings) and enqueues them as pending curation candidates — never deletes anything. Review the returned pairs, then consolidate via tim_move_entry/tim_delete, or reject.

tim_import_audit

Post-import audit for hmem migrations: missing sections, duplicate sections, loose imported nodes, health issues, and repair suggestions.

tim_dry_run_move

Preview tim_move_entry impact without writing: current parent/depth, target parent/depth, descendant count, and cycle risk.

tim_repair_section

Ensure a canonical project section exists and optionally move specified children into it. Uses TIM writes/moves, never SQL edits.

tim_doctor

Run comprehensive diagnostics: config, DB, API connectivity.

tim_session_start

Start a TIM session (idempotent). With projectId (or default P0000 Inbox), creates nested Sessions/Summary/Exchanges tree. Without a resolvable project the response lists recently active projects — follow its ACTION line to bind one.

tim_resume_list
tim_resume_topic
tim_preview_briefing
tim_session_resume
tim_session_log

Append exchange entries to a session log.

tim_show_unsummarized

Return the next unsummarized batch of exchanges for a session (UUIDs + user/agent bodies). Summarizer reads this, writes a Batch node under Summary.

tim_show_all_unsummarized

Scan ALL sessions and return every unsummarized batch. Use at startup for cleanup sweep of stale batches (crashed summarizer, missed triggers). No parameters needed.

tim_show_untagged

Return batch-summary nodes that have only structural tags (#session-summary, #batch-summary) and no content hashtags. Use for re-tagging failed or legacy summaries.

tim_write_batch_summary

Write an idempotent Batch summary node under the session Summary tree. Used by tim-summarizer CLI.

tim_rollup_session_summary
tim_record_commit

Record a git commit under the project Commits section. Idempotent by hash. Links to session via relates/implements when sessionId given.

tim_checkpoint
tim_hook_prompt_submit
tim_rename_entry

Atomically rename an entry ID and update all references (edges, parent_id, staging, metadata).

tim_move_entry

Move an entry under a new parent and cascade depth updates to descendants. Preview with tim_dry_run_move before moving imported or ambiguous nodes.

tim_update_many

Batch-update irrelevant and/or favorite flags on multiple entries (flags only, never content).

tim_tag_add

Add tags to an entry (deduplicated). Deprecated status/priority tags (#todo, #done, #priority-*) are skipped — use metadata.task.status / metadata.task.priority.

tim_tag_remove

Remove tags from an entry.

tim_tag_rename

Rename a tag across all entries (exact match only, safe for substring collisions).

tim_create_project

Create a project in exactly one mode. Every project representing files on disk MUST pass its absolute path; memoryOnly:true is only for an intentionally virtual/database-only project and is never a shortcut for an unknown cwd.

tim_load_project

Load a project by label or alias and bind the session once. Rejects a different project if the session is already bound — pass bind:false for cross-project reads (replaces tim_read_project).

tim_read_project

[DEPRECATED — use tim_load_project with bind:false] Read a project brief + tree WITHOUT binding the session (cross-project lookup). Use tim_load_project to start working on a project.

tim_show
tim_task_order
tim_error_stats

Show error statistics: total errors, top errors, error rate, alert thresholds (>5 identical errors in 1h).

tim_error_log

Log an error entry. Used by CLI tools and summarizer for structured error tracking.

tim_remember

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

55/55 tools missing one or more hints — tim_read (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); tim_write (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); tim_write_many (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +52 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tool test coverage

42/55 tools referenced in tests (76%)

Write tests that reference each tool by name so every tool has at least one test.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
