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.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
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_readtim_writetim_write_manytim_searchtim_guardtim_deltatim_linkCreate an edge (relationship) between two entries.
tim_unlinktim_traceFollow an edge chain from a starting entry (BFS traversal).
tim_updatetim_verifyRe-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_deleteDelete an entry (soft: mark irrelevant, hard: tombstone).
tim_delete_batchBatch hard-delete entries by id (max 100). Skips missing ids.
tim_syncSync operations: push staging records, pull from remote, or check status.
tim_suppressSuppress 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_healthRun health diagnostics: broken links, orphans, FTS integrity, counts, memory coverage and embedding backlog.
tim_statsContent statistics: entry counts, content size aggregates, length buckets, and breakdown by metadata.kind.
tim_section_childrenList direct children of a project section in compact form.
tim_exportExport TIM database to markdown or .hmem SQLite format.
tim_importImport 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_manifestRead a .hmem file without importing it: format, labels, titles, and node counts.
tim_project_structureReturn one project structure: root, direct sections, duplicate sections, loose direct children, and imported hmem provenance.
tim_find_duplicatesReport-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_auditPost-import audit for hmem migrations: missing sections, duplicate sections, loose imported nodes, health issues, and repair suggestions.
tim_dry_run_movePreview tim_move_entry impact without writing: current parent/depth, target parent/depth, descendant count, and cycle risk.
tim_repair_sectionEnsure a canonical project section exists and optionally move specified children into it. Uses TIM writes/moves, never SQL edits.
tim_doctorRun comprehensive diagnostics: config, DB, API connectivity.
tim_session_startStart 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_listtim_resume_topictim_preview_briefingtim_session_resumetim_session_logAppend exchange entries to a session log.
tim_show_unsummarizedReturn 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_unsummarizedScan 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_untaggedReturn 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_summaryWrite an idempotent Batch summary node under the session Summary tree. Used by tim-summarizer CLI.
tim_rollup_session_summarytim_record_commitRecord a git commit under the project Commits section. Idempotent by hash. Links to session via relates/implements when sessionId given.
tim_checkpointtim_hook_prompt_submittim_rename_entryAtomically rename an entry ID and update all references (edges, parent_id, staging, metadata).
tim_move_entryMove 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_manyBatch-update irrelevant and/or favorite flags on multiple entries (flags only, never content).
tim_tag_addAdd tags to an entry (deduplicated). Deprecated status/priority tags (#todo, #done, #priority-*) are skipped — use metadata.task.status / metadata.task.priority.
tim_tag_removeRemove tags from an entry.
tim_tag_renameRename a tag across all entries (exact match only, safe for substring collisions).
tim_create_projectCreate 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_projectLoad 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_showtim_task_ordertim_error_statsShow error statistics: total errors, top errors, error rate, alert thresholds (>5 identical errors in 1h).
tim_error_logLog an error entry. Used by CLI tools and summarizer for structured error tracking.
tim_rememberDisclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
TIM_DB_PATHTIM_EXPOSE_INTERNAL_TOOLSTIM_MCP_HOSTTIM_MCP_PORTTool 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.
