"Vault" matching MCP servers:

A self-hostable semantic skill registry for AI agents, providing searchable, versioned, and verified skills over a single MCP endpoint with per-agent private vaults and trust tiers.

Agent Vault is a local credential vault for AI agents. It enables agents to use secrets by name without ever seeing their values, with host allowlists, output scrubbing, and audit logging.

Enables AI coding agents to securely inject API keys and secrets into environment files, configs, or commands without the agent ever seeing the secret values.

Human-in-the-loop secret access for AI coding agents, enabling approval workflow for password manager secrets via MCP.

Governed, tamper-evident memory and audit trail for AI agents with 0G Merkle segment sealing. Records agent actions in append-only namespaces with hash chaining, seals segments to 0G Storage, and supports audits and retention enforcement.

MCP server for agent-native secrets management that stores encrypted secrets with AES-256-GCM, issues short-lived scoped tokens, and injects secrets into requests server-side so agents never handle plaintext credentials.

Enables secure credential storage for AI agents by encrypting secrets and providing agent-invisible references, ensuring sensitive data never leaks to the model.

Enables AI agents and MCP clients to securely store, retrieve, and manage encrypted credentials without hardcoding API keys.

An MCP server for using Bitwarden Secrets Manager as durable credential storage for agent workflows, enabling secure secret storage, retrieval, and injection into trusted executables.

A neutral authority layer for agent runtimes, providing sovereign verification and vault-governed custody tools via MCP.

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.

Multi-workspace Slack MCP server with draft+confirm safety, vault auto-export, and triple-mode auth.

Local explicit memory vault exposing MCP tools for storing, searching, and managing memories, providing a shared memory layer for agents like Codex and ChatGPT.

Enables AI agents to manage secrets and credentials from a secure vault via MCP tools over stdio.

Enables AI agents to execute vault payments under explicit human control via policy-gated tools (balance checks, deposits, redemptions, transfers) with human review escalation for risky actions.

Offline-first MCP proxy with policy engine and immutable audit trail for secure AI coding agents.

Enables autonomous bug bounty hunting with H1 auto-submit, profit tracking, and a live dashboard. Coordinates real-time state, credential vault, session management, and payload generation for MCP-compatible AI agents.

Enables Alexa+ to monitor budgets, check affordability, recommend Amazon deals within spending limits, and execute automated purchase plans through MCP tools.

Provides a zero-knowledge credential vault for AI agents, allowing secure storage, retrieval, and management of secrets with cross-agent delegation and tamper-evident audit.

Enables AI agents to register and discover marketplace services, search the web, retrieve weather and trends, contact the Bagira assistant, and access knowledge vault digests over MCP.
