Vanguard Memory Node tools (11, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • vmn_deletewrite action

    Delete a memory object from the local vault by its SHA-256 root hash. This is permanent.

  • vmn_index_status

    Return the current status of the BM25 inverted index. Indicates if a rebuild is needed.

  • vmn_ingest

    Ingest text into the local Vanguard Memory Vault. Returns a SHA-256 shard hash.

  • vmn_ingest_file

    Ingest new content from a file into the vault, tracking progress with a cursor so only new lines are ingested on each call. Safe to call repeatedly — only the delta since the last call is stored.

  • vmn_inspect

    Inspect the catalog metadata for a specific memory shard by its SHA-256 root hash.

  • vmn_list

    List all memory objects in the local vault. Optionally filter by namespace.

  • vmn_rebuild_index

    Rebuild the BM25 inverted index from existing vault objects. Safe to run at any time — objects are never modified.

  • vmn_recall

    Recall evidence from a local Vanguard Memory shard using deterministic xLMP lexical search.

  • vmn_search

    Search across all memory objects in the vault by keyword query. Returns candidate roots. Use vmn_recall with a specific root to retrieve full evidence.

  • vmn_stats

    Return statistics about the local Vanguard Memory Vault.

  • vmn_sync_vault

    Sync a local memory object to the ExergyNet LNES-17 vault. Requires EXERGYNET_API_KEY env var.

What the publisher says

From the Vanguard Memory Node repository's README, as published. We do not edit it. Read it on GitHub

Vanguard Memory Node (VMN)

Local deterministic memory for AI agents via the Model Context Protocol (MCP).

No cloud. No vector database. No semantic drift. Your data stays on your machine.

What it does

VMN gives any MCP-compatible AI agent a persistent, queryable memory vault stored entirely on local disk. Text is ingested once, content-addressed with SHA-256, segmented, and indexed with a sharded BM25 inverted index. Retrieval is deterministic: the same query always returns the same ranked result from the same data.

Optionally, vaults can be synced to the ExergyNet LNES-17 ledger for cross-device and cross-agent recall with cryptographic provenance.

Install

npm install -g @lnes/vanguard-memory-node

Or run without installing:

npx @lnes/vanguard-memory-node

Tools (11 total)

vmn_ingest

Stores text as a SHA-256 content-addressed shard. Segments it, indexes it, and updates the local catalog.

Returns: SHA-256 root hash + vault path + vault_synced flag.

vmn_recall

Retrieves a 900-character evidence window from a specific shard using lexical BM25 scoring.

Returns: best-matching evidence window, or a human-readable no-match message.

vmn_search

Full-vault keyword search across all ingested objects. Returns ranked results with snippets.

vmningestfile

Delta-ingests a growing file into the vault, tracking progress with a cursor so only new lines are ingested on each call. Designed for Stop hooks and continuous log pipelines — safe to call repeatedly with no duplicates.
