Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • context_briefContext Briefingread-only

    Generate a compact context briefing: relevant memory + active sessions + project health. Single call instead of 5-6 separate calls. Zero LLM, pure deterministic logic.

  • context_diffContext Diffread-only

    What changed since the last session: git commits + modified files + new/updated memory entries. Zero LLM.

  • context_exportExport Memory as Markdownread-only

    Export all memory as markdown injectable for other agents or sessions. Full (detailed) or compact format. Zero LLM.

  • context_focusFocus Context for Taskread-only

    Hyper-focused context for a specific task: relevant entries + related files + code referencing the symbol + existing tests. Zero LLM.

  • context_generateGenerate Full Contextread-only

    Generate a full system prompt: project (package.json, deps, framework) + git (branch, commits) + memory (relevant entries) + sessions. Single call to prepare the agent. Zero LLM.

  • context_healthMemory Health Auditread-only

    Full memory health audit: orphan links, duplicates, broken refs, expired TTL, quality, stale sessions. Includes score 0-100. Zero LLM.

  • memory_archiveArchive Old Entriescan change or delete data

    Move old entries (>30 days) to archive.toon to keep memory clean.

  • memory_backupBackup Memory

    Create a timestamped backup of the memory file. Use before major operations or to preserve state.

  • memory_capturedList Captured Activity

    Show activity log captured automatically by hooks (only if capture is enabled). Useful for promoting observations to memory with memory_remember.

  • memory_checkpointSession Checkpoint

    Save or update a session checkpoint with 7-day TTL. Creates a knowledge entry snapshot of the current session state. Same session = upsert (single checkpoint per session). Auto-expires.

  • memory_compressCompress Memory Entriesread-only

    LLM-powered compression: select entries to compress into one concise entry. The agent (YOU) reads the entries, writes a compressed summary, then calls memory_remember to save it. Two-step dance: this tool provides context, you provide intelligence.

  • memory_consolidateConsolidate Memorycan change or delete data

    Cleanup operations, all deterministic (no LLM): identical removes duplicate entries (keeps the first), similar merges entries with >50% word overlap (keeps longer content, combines tags), low-quality removes entries below minQuality or without tags, versions marks entries describing the same subject with older versions obsolete in favor of the newest.

  • memory_decryptDisable Encryptioncan change or delete data

    Disable encryption and decode memory.

  • memory_diffMemory Diffread-only

    Show what changed in memory since a date. Useful for seeing what was learned since the last session.

  • memory_encryptEnable Encryptioncan change or delete data

    Enable AES-256-GCM encryption for memory. Requires TOON_MEMORY_KEY in environment.

Show 23 more tools
  • memory_export_gistExport to GitHub Gist

    Export memory to a private GitHub Gist for cloud sync. Requires GITHUB_TOKEN env var. Zero deps — uses Node's built-in fetch().

  • memory_export_globalExport to Global Memory

    Write the current project memory to the global memory file (~/.toon-memory/memory/global.toon, or TOON_MEMORY_GLOBAL_FILE). One-shot: the global file is a plain TOON document you curate and import into other projects with memory_import_global.

  • memory_forgetForget from Memorycan change or delete data

    Lifecycle operations for a memory entry: soft (default) marks it obsolete and hides it from recalls, hard permanently removes it, restore brings it back to active, supersede retires it with a typed superseded_by edge to a newer entry.

  • memory_graph_pathFind Graph Pathread-only

    Find the shortest path between two memory entries in the knowledge graph. Shows how two concepts are connected through related entries.

  • memory_import_gistImport from GitHub Gistcan change or delete data

    Import memory from a GitHub Gist. Merges entries (keeps newer dates, combines tags). Requires GITHUB_TOKEN env var.

  • memory_import_globalImport Global Memorycan change or delete data

    Merge cross-project conventions from the global memory file (~/.toon-memory/memory/global.toon, or TOON_MEMORY_GLOBAL_FILE) into this project. One-shot merge by key: keeps newer dates, unions tags/links, preserves all fields. Deterministic and offline.

  • memory_merge_sessionsMerge Session Observations

    Merge observations from multiple sessions/branches into a consolidated view. Deduplicates and suggests entries to promote to memory. Inspired by Hindsight's multi-agent session merging.

  • memory_pinPin Entry

    Pin a memory entry with priority level (1-5). Higher priority entries appear first in recalls. Default: 1. Useful for critical decisions, project rules, or frequently-needed context.

  • memory_primerSystem Primerread-only

    Generate a compact system primer: always-current knowledge map for auto-injection into agent context. Excludes private entries, shows top memories by importance, categories, and patterns. Use at session start or when context feels stale.

  • memory_promotePromote Observations

    Heuristic auto-promote from the capture log (no LLM). Each observation gets a deterministic confidence score; high-confidence ones promote as active entries, low-confidence (≤ minConfidence) become reviewable drafts. Opt-in: run with dryRun: true first.

  • memory_recallSearch Memory

    Search the project's persistent memory. Returns relevant entries. Use BEFORE reading files. Pattern: recall → context_diff for recent changes → capture to save observations.

  • memory_reflectReflect on Memoryread-only

    Deterministic memory audit (no LLM): tag co-occurrence themes, hub/orphan entries, near-duplicates, contradiction candidates, stale entries, and superseded-but-active entries. Signals what to link, merge, or retire.

  • memory_rememberSave to Memory

    Save a fact to the project's persistent memory (decisions, patterns, bugs, knowledge). Persists between sessions. Tags: 'private' excludes from context injection; 'superseded' marks as obsolete.

  • memory_searchUnified Search

    Search memory with combined filters: text query, category, tags, and date range. Returns ranked results.

  • memory_secretEncrypted Secrets Vault

    Store/retrieve secrets in the encrypted sidecar vault (secrets.toon, AES-256-GCM). Keeps data.toon readable and open while sensitive values stay encrypted at rest. Requires TOON_MEMORY_KEY. 'store' encrypts, 'get' decrypts, 'list' shows metadata only (no values), 'forget' removes.

  • memory_sessionsActive Sessions & Conflictsread-only

    Show active agent sessions in this project (git branch, files touched, last-seen) and detect soft conflicts (files touched by 2+ sessions). Use at startup to avoid overwriting other parallel sessions' work.

  • memory_smart_recallSmart Recall (Unified)read-only

    Unified retrieval: combines BM25 + graph + decay + quality in a single call. Use at the START of each task to get all relevant memory context. Then use context_diff for recent changes, context_focus for deep dives.

  • memory_statsMemory Statsread-only

    Show project memory statistics.

  • memory_suggestSuggest Related Memoriesread-only

    Suggest memory entries related to a given context. Useful for gathering context before a task.

  • memory_summaryFile Summary

    Save or retrieve a summary of a large file to save tokens.

  • memory_tagBatch Tag Operations

    Batch add, remove, or set tags on one or more memory entries by key or id.

  • memory_unpinUnpin Entry

    Remove the pin from a memory entry so it returns to normal ranking.

  • memory_visualizeOpen Memory Graph Viewerread-only

    Open the interactive memory graph viewer (force-directed graph, stats, timeline, detail panel). Renders inline in MCP Apps-compatible hosts.
