"Memory" matching MCP servers:

Persistent encrypted memory for AI agents. E2E encrypted private vaults, shared knowledge commons, topic channels, and agent-to-agent DMs. 23 MCP tools, free, no API key needed.

Enables AI assistants to keep and retrieve private context locally, with verifiable receipts and optional Solana anchoring for public proofs.

Enables agents and MCP clients to retain, recall, screen, quarantine, approve, supersede, and verify durable memories with session-level provenance. Every write passes a poisoning gate, so suspicious or secret-bearing entries are held for human review rather than silently trusted in later sessions.

Gives AI agents a shared, encrypted memory store accessible over MCP, with per-agent keys, per-namespace permissions, history and revert, attachments, and semantic search that handles Czech as well as English. Memories, agents, network access, and HTTPS can be managed through a self-hosted admin web on the same port, with backups being simply copies of the encrypted data file.

Enables MCP clients to save, semantically recall, and delete long-term facts and decisions entirely offline, with encrypted storage, automatic secret redaction, and multilingual local embeddings.

Enables capturing a tamper-evident, hash-chained local record of every AI agent tool call — both the decision before a tool runs and its outcome — so you can review what the agent actually did in order, detect edits, deletions, or reordering at the exact index, and export a signed evidence pack any third party can verify with no installs.

Enables AI tools and agents to share a persistent memory space, so a decision, task, or encrypted secret saved in one client can be searched, recalled, and handed off from another. It also tracks goals day by day, moves unfinished work between sessions, and keeps exports, trash recovery, and per-account isolation under the user's control.

Guardrails for AI coding agents that enforces rules via compliance receipts, blocking destructive actions and syncing rules across all AI tools.

Enables security analysts to carry structured investigation state across sessions by storing typed observations, hypotheses, tasks, evidence and versioned decisions in a local SQLite graph with full-text search. It also enforces authorized scope and request controls, redacted and content-hashed evidence, duplicate-test signatures and validation gates that leave findings in draft until reproducibly confirmed, then produces technical and executive reports for Antigravity, Codex and other stdio MCP clients.

Enables devices and agents to share a self-hosted memory store over a remote Streamable HTTP MCP endpoint, with hybrid retrieval, scoped access tokens, and encrypted vault references for sensitive data.

Enables MCP-compatible AI agents to save encrypted, DID-signed session checkpoints and resume the latest state across sessions, while keeping secrets and credentials in a local vault.

A tool for detecting and cleaning Java memory shells via local or SSH remote execution. It enables AI agents to scan Java processes, analyze suspicious class code, and safely remove memory shells after user confirmation.

Enables agents to store and retrieve hierarchical memory in cryptographically partitioned namespaces, with HMAC-based isolation and Ebbinghaus time-decay so recall fades realistically over time. Runs as a zero-dependency Python STDIO MCP server that returns deterministic JSON results.

AI-powered memory dump analysis using Volatility 3 for digital forensics investigations. Enables process analysis, malware detection, network forensics, timeline generation, and anomaly detection with support for Claude, Llama, and other LLMs.

Enables AI agents to query and record SOC analyst reasoning via a knowledge graph, allowing access to institutional memory from Splunk.

Stamp and verify Bitcoin-anchored OpenTimestamps memory receipts for AI agents (stamp_memory / verify_receipt).

An MCP server that provides a guarded interface to the mem9 persistent memory backend, protecting AI agents against prompt injection, secret leakage, and memory poisoning.

Multi-tier memory forensics MCP server combining a fast Rust engine with Volatility3 coverage for analyzing memory dumps.

Lets multiple AI agents and parallel coding sessions share one memory and task ledger, so they can claim work instead of duplicating it, resume each other's handoffs and reasoning, and use credentials without ever seeing the keys. Connects assistants such as Claude Code, Codex, Cursor, Gemini, ChatGPT and custom agents over MCP, backed by a single local SQLite file or a self-hosted Postgres hub.

Enables Nest applications to expose decorated provider methods as MCP tools, resources, and prompts over Streamable HTTP or stdio, with Nest guards, interceptors, pipes, filters, OAuth 2.1 resource-server support, and an in-memory test client.

Encrypted memory for Claude, on a server you deploy to your own Cloudflare account.

Enables AI agents to perform read-only low-level disk forensics and data recovery by opening physical drives or disk images, scanning filesystem structures, testing in-memory patches, and extracting recovered files.

Enables local, privacy-mode incident handoffs with four fixed questions, pattern-guarded redaction, human-review drafts, and optional in-memory data clearing.

Enables MCP clients to triage SOC alerts while enforcing a trust firewall across retrieval, memory, and privileged actions. It exposes tools for alerts, logs, memory, and alert actions, with defenses that refuse risky operations in the presence of attacker-controllable content.

Enables AI agents to analyze memory dumps for forensic investigation, leveraging a fast Rust engine and full Volatility3 plugin coverage via the Model Context Protocol.

Provides persistent memory, cryptographic audit trail, and HMAC-verified skill admission for Claude Code, running locally on PostgreSQL with zero cloud sync.

Access control, conflict resolution, and audit for shared agent memory. Policy-gated memory tools over Postgres + pgvector, exposed via MCP.

Exposes Colber's five integrated services (Reputation, Memory, Observability, Negotiation, Insurance) as 27 MCP tools for AI agents, enabling trust, coordination, and continuity.

A local-first memory vault MCP server for Windows that exposes an encrypted user memory store to agents via a permission-brokered protocol, ensuring user ownership and control over browsing data.

An MCP server that enables conversational Windows memory forensics through Volatility 3, letting an assistant inspect processes, network connections, registry artifacts, kernel objects, and other evidence artifacts from a memory image using natural-language questions. It also provides cross-plugin correlation tools for triage and anomaly detection, plus image-integrity verification, all against a single session-bound evidence image.
