"Vault" matching MCP servers:

An MCP server that provides authorization middleware for AI agents using private data, enabling consent management on Aleo and local private inference with persistent policy storage.

BYOK vault and provider API key usage guidance for MCP-capable agents.

A local-first MCP server that gives AI coding agents persistent memory and controlled commands. Features a git-backed markdown knowledge vault with FTS5 search, surgical section edits, token-aware context budgeting, and a sandboxed command engine with human approval gates. Works with Claude Code, Cursor, Copilot, Gemini, and more.

engRAM provides encrypted, offline, RAM-resident memory for AI agents via MCP, enabling fast hybrid search, deterministic importance-based recall, and secure vault management with tools like memory_search, memory_store, and memory_forget.

An MCP bridge for ProphetKey, an offline-first encrypted API key vault for AI agents. Use one of the 5 prophetkey_* tools to inject real API keys through a local proxy — agents only ever see safe_key identifiers, never the real provider keys.

Provides on-chain trust verification for AI agents through the Vaultfire Protocol, enabling read-only trust checks and write operations like agent registration and partnership bonds across multiple blockchains.

Centralized encrypted gateway that routes requests to 11+ LLM providers (API keys and CLI subscriptions) through a single OpenAI-compatible endpoint, with MCP tools for vault operations, code search, and shared state.

Self-hosted MCP server exposing a brain's tool registry (vault search, vault access, and connector tools) to MCP clients like Claude Code, scoped to the box owner.

Enables voice captures from a smart ring to search and append notes in a local Obsidian vault and query an OpenAI-compatible AI agent, returning answers as phone notifications.

Enables forwarding Douyin or Bilibili video shares to Kimi for AI analysis and automatically writing the resulting Chinese notes into an Obsidian vault.

Enables a private, local-first AI agent that uses your Obsidian vault as memory, exposing an ask_seastar tool to any MCP host and consuming other MCP servers while running entirely on your machine with any OpenAI-compatible local model.

Enables AI agents from an MCP client to control Google Flow through a signed-in Chrome session, generating videos and images with Veo, Nano Banana, and Omni while managing projects, assets, scenes, characters, and shot lists with spending-approval guards and a sandboxed file vault.

Visibility-aware knowledge vault for AI agents with 20 MCP tools.

AI health checkups, token usage, LLM cost optimization, BYOK vault guidance, provider usage visibility, and read-only cleanup audits for MCP-capable agents.

Connect your AI tools to your prompt vault. Gildara gives agents structured operating contracts: prompts with roles, tools, stop conditions, and output schemas, fetched at runtime via API. 6 tools: list, get, resolve, run (with auto-repair), create prompts, and browse agent blueprints.

Remote MCP server for PII detection, de-identification, tokenization, and re-identification using a Skyflow Vault.
