MCP servers for long-term memory and vector search: store notes, embeddings and facts so an AI assistant remembers across sessions. 799 servers in this category.
Gives AI agents semantic, episodic, and procedural memory that persists across sessions and learns from failed workflows.
$claude mcp add --transport http mengram https://mengram.io/mcp
Provides a Git-backed permanent memory for AI agents to share durable, human-readable Markdown memories across different clients.
$claude mcp add perenna -- uvx perenna
Provides persistent, local-first searchable memory for AI agents using hybrid vector and keyword retrieval.
$claude mcp add memo -- uvx mlx-memo
Provides fully local, air-gapped semantic memory for AI agents with deterministic storage and point-in-time fact retrieval.
$claude mcp add genome -- uvx genome-memory
Provides persistent memory for Claude Code by automatically saving and retrieving conversation context, decisions, and preferences across sessions.
$claude mcp add memory-mcp -- uvx chenxiaofie-memory-mcp
Provides a token-light local memory layer for AI agents using SQLite with hybrid BM25 and dense retrieval.

Provides a local-first persistent memory and knowledge graph for AI coding agents to store decisions, patterns, and indexed documentation.
$claude mcp add turbo-quant-memory -- uvx turbo-quant-memory
Provides persistent, evidence-backed memory for AI agents by linking claims to their original source events and review history.
$claude mcp add provena -- uvx provena-agent-memory
Provides an MCP interface to an existing Open Agent Memory deployment for cited memory recall and durable information retention.
$claude mcp add oam -- npx -y @rocke-dong/oam-mcp
Provides persistent, scoped memory for AI agents through four explicit stdio tools for searching, adding, updating, and deleting memories.
$claude mcp add qdrant-memory-mcp -- uvx qdrant-memory-mcp
Provides hosted memory for AI agents with provenance, contradiction surfacing, and snapshot rollback capabilities.
$claude mcp add bilinc -- uvx bilinc
Lets AI coding assistants run semantic code search, symbol graph navigation, and persistent memory queries over an indexed codebase.
Provides automatic local memory capture and recall for AI agents using a single SQLite file to maintain long-term context across sessions.
Gives AI agents persistent local memory with semantic recall, structured facts, and cross-agent context sharing.
Provides persistent, workspace-isolated codebase memory for IDEs using local vector indexing and tree-sitter parsing.
Provides a self-evolving Zettelkasten-style memory graph that allows AI agents to store, link, and evolve knowledge through semantic and structural search.
$claude mcp add a-mem-mcp -- uvx a-mem
Lets an AI client semantically search markdown vaults, trace multi-hop note connections, and find hub or orphaned notes.
Provides long-term Markdown-based memory for AI coding agents that runs locally and allows for explicit session handoffs.
$claude mcp add memtomem -- uvx memtomem
Provides persistent, AES-256-GCM encrypted memory infrastructure for AI agents to enable cross-session and cross-agent context recall.
$claude mcp add --transport http synapse-layer https://forge.synapselayer.org/api/mcpProvides persistent multimodal context storage for LLM agents with support for text, images, semantic search, and thread-based scoping.
