Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Document Metadata Flattener.

  1. 01

    Flatten metadata

    This capability converts complex nested metadata objects into a flat dictionary using dot and bracket notation for keys.

  2. 02

    Get metadata summary

    This capability provides a statistical overview of how complex a specific metadata object is.

  3. 03

    Validate metadata schema

    This capability checks if a metadata object stays within your required depth or structural constraints.

Real work

What teams actually run

01

Vector Database Ingestion

Transforming raw document metadata into a flat format compatible with Chroma or FAISS.

02

RAG Pipeline Debugging

Checking if metadata objects are too deep or complex for your specific retrieval setup.

03

Data Cleaning

Standardizing inconsistent JSON structures into a uniform dot-notation format.

04

Schema Enforcement

Ensuring incoming metadata meets strict structural requirements before storage.

One connector, every AI

Document Metadata Flattener works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Document Metadata Flattener to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 3 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Document Metadata Flattener, so you can see the experience inside your AI.

It does not authenticate your account with Document Metadata Flattener. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work Document Metadata Flattener owners hand off.

This MCP is built for engineers working on retrieval-augmented generation and vector database management.

  • 01

    AI Engineers

    They hand off raw document metadata to the MCP to prepare it for vector indexing.

  • 02

    Data Engineers

    They use it to validate and transform JSON structures before they hit the database.

  • 03

    MLOps Specialists

    They use the summary and validation capabilities to monitor metadata complexity in production pipelines.

FAQ

Questions Document Metadata Flattener owners ask.

  • 01

    What does dot-notation mean in this context?

    It means nested keys are converted into a single string separated by dots, like parent.child, to make them readable by flat databases.

  • 02

    How does this MCP handle arrays?

    It uses bracket-notation, such as tags[0], to flatten array elements into individual keys.

  • 03

    Which vector databases is this compatible with?

    It is designed for any vector store that requires flat metadata for filtering, such as Chroma or FAISS.

  • 04

    Can I check if my metadata is too complex?

    Yes, you can use the get_metadata_summary capability to get a statistical overview of the object's complexity.

  • 05

    Do I need to host this myself?

    No, Vinkius hosts and manages the MCP for you. You just connect your client and it works.

  • 06

    Why do I need to flatten my metadata?

    Many vector databases, such as Chroma or FAISS, cannot filter based on nested JSON objects. Flattening converts these into a single level of keys, making them searchable.

  • 07

    How does the capability handle arrays?

    The capability uses bracket-notation for array elements. For example, an array at tags becomes tags[0], tags[1], etc.

  • 08

    What happens if there is a key collision?

    If two different paths result in the same flattened key, the capability detects the collision and prioritizes the first encountered value to prevent silent data loss.
