In-depth architectural comparison of the Doc Manager and Iai Personal Memory Engine MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Doc Manager
Knowledge & Memory · Remote HTTP/SSE
Quality: 53/100 (Good) | Auth: OAuth 2.0
Iai Personal Memory Engine
Knowledge & Memory · Local stdio
Quality: 67/100 (Great) | Auth: No auth required
Verdict Summary: Choose Doc Manager if you need specialized Knowledge & Memory tools running via a hosted cloud SSE transport. Choose Iai Personal Memory Engine if your workspace requires Knowledge & Memory integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Doc Manager when:
You need dedicated capabilities in the Knowledge & Memory domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: OAuth 2.0 (Free / Open Source).
You have access to required keys: AZURE_STORAGE_ACCOUNT, AZURE_STORAGE_ACCESS_KEY, RUST_ROCKET_EXACT_ORIGIN, OAUTH_PROVIDER, OAUTH_PUBLIC_BASE_URL, OAUTH_ALLOWED_USERS, MCP_READ_ONLY.
Personal document vault on Azure Blob Storage with a built-in MCP server. Client-side AES-256-GCM zero-knowledge encryption: encrypted docs stay opaque to Claude, plaintext docs are fully readable, writable, and searchable from chat.
Local memory daemon for any MCP-over-stdio client with three-tier storage (episodic/semantic/procedural). Own SQLite + hnswlib store (Hippo) with bge-small-en-v1.5, MIT-licensed community-detection reranking (MOSAIC), and sleep-cycle consolidation. AES-256-GCM encrypted at rest, no telemetry. Verbatim recall >=99% and post-contradiction Rescue@10 1.000 at honest scale. Ambient capture via shell hooks. Windows support in beta.
Tools & Capabilities Breakdown
Doc Manager Tools (9)
list_documents
List every doc with `id`, `title`, `encrypted` flag, attachment info, size
get_document
Fetch one plaintext document by id; refuses encrypted ones
search_documents
Case-insensitive substring search over titles (always) and plaintext content
get_attachment
Fetch the file attached to a doc (filename, bytes, base64, UTF-8 if applicable)
create_document
Create a new plaintext document; returns the new id
update_document
Replace content (and optionally title) of a plaintext document
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Doc Manager is categorized under Knowledge & Memory and uses a remote streaming HTTP/SSE transport. In contrast, Iai Personal Memory Engine belongs to Knowledge & Memory using local stdio subprocess. Select Doc Manager when you need capabilities focused on knowledge & memory and Iai Personal Memory Engine when you require tools for knowledge & memory.
Attach a file (text or base64-encoded binary) to a doc; replaces any existing
delete_document
Delete a document and all its blobs (main, title, attachment); irreversible
delete_attachment
Delete only the attachment of a document, leaving the document itself intact
Iai Personal Memory Engine Tools (9)
memory_recall
Cue-based recall — returns hits **and anti-hits**: memories that *contradict* the cue surface next to the ones that match, so a stale fact can't masquerade as current.
memory_temporal_recall
Time-anchored recall — *"what did I say about pricing in May?"*
memory_recall_structural
Retrieve by the *shape* of a memory (the HD substrate), not just its embedding.
memory_search
Plain text search over the store.
memory_capture
Write a memory explicitly (ambient capture normally does this for you).
memory_contradict
Record that a fact changed. The old version is archived, not erased — both stay retrievable. That's the Rescue@10 and historical-verbatim story in the [benchmarks](#benchmarks).
memory_reinforce
Strengthen a memory's recall pathways.
memory_consolidate
Run a consolidation pass now instead of waiting for idle.
profile_get_set
The eleven sealed procedural knobs the engine learns about you.
