MCP-native file vault

Give your AI assistant
a secure file vault

Vaulken connects your AI tools to S3 storage via the Model Context Protocol. Read, write, search, and organize files with scoped permissions and full audit control.

Everything your AI needs

Complete file management for your AI, from simple reads to semantic search and PDF extraction.

File operations

Read, write, append, patch, move, and delete files. Your AI can manage an entire knowledge base autonomously.

Full-text & semantic search

Exact substring search across all files, plus meaning-based vector search powered by embeddings.

Secure by default

OAuth 2.0 authorization with read-only or read-write scopes per client. Path-level access control included.

Bring your own bucket

Connect any S3-compatible storage: Scaleway, AWS, MinIO, Cloudflare R2. Your files stay in your infrastructure.

Markdown-native

Outline extraction, section-level editing, and frontmatter management. First-class support for Obsidian vaults.

PDF extraction

PDFs are automatically converted to text via OCR. Your AI reads the content, not the binary. Results are cached for instant access.

How it works

Three steps to connect your AI to your files.

1

Create a vault

Bring your own S3 bucket or let Vaulken provision managed storage. Set permissions and path scoping from the dashboard.

2

Get your MCP URL

Each vault comes with read-write and read-only MCP URLs. Copy the one you need from the dashboard.

3

Connect your AI

Point Claude Desktop, Cursor, or any MCP client to your Vaulken server. Your AI can now read, write, and search your files.

Security first

Your files never touch our servers. Only irreversible vector indexes are stored for semantic search.

Zero-knowledge storage

File contents stay in your S3 bucket. We never read, copy, or cache your files.

Encrypted credentials

S3 keys are encrypted at rest with a hardware key management service. Never stored in plaintext.

EU-hosted

All infrastructure runs in Paris, France. Your data never leaves the European Union.

No AI training

Your data is never used to train or improve any model. No exceptions.

Simple pricing

Free to start. One paid plan for everything else.
