What is JSONPath Extractor?

It is an MCP that allows your AI client to navigate and select specific data from JSON structures using JSONPath expressions.

Which AI clients can use this MCP?

You can use this with any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.

Can I test my JSONPath before running it?

Yes, you can use the validate_expression_syntax capability to check if your path logic is correct without executing it against the data.

Does this MCP host the data?

No, this MCP provides the capabilities to process the data you provide to your agent. Vinkius hosts the MCP itself so it is ready to use immediately.

Can it handle large JSON files?

Yes, it is designed to navigate complex and deeply nested JSON structures using standard selection logic.

How do I verify if my JSONPath is correct?

You can use the validate_expression_syntax capability to check the syntax of your expression without needing to provide a JSON object.

Can I extract multiple values at once?

Yes, using evaluate_path with wildcards or slice notation will return an array of all matching elements found in the JSON object.

How can I check the nesting level of a specific path?

The get_path_metadata capability provides the depth and whether the path terminates at a leaf node or a container.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

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

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through JSONPath Extractor.

01
Evaluate path
This capability performs the actual data extraction using your JSONPath expression. It returns the specific values you targeted.
02
Get path metadata
This capability inspects the JSON object to show you the structure and complexity relative to a specific path. It helps your agent understand the depth of the data it's looking at.
03
Validate expression syntax
This capability checks your JSONPath expression for syntax errors. It verifies the logic is sound without actually running it against your data.

Real work

What teams actually run

API Response Parsing

Your agent pulls a specific user ID or token from a large, nested API response.

Log Analysis

The agent extracts error codes or timestamps from structured JSON log files.

Data Transformation

You use the MCP to grab specific subsets of data to prepare for a database upload.

Configuration Auditing

The agent checks specific settings within a large JSON configuration file to ensure they meet requirements.

One connector, every AI

JSONPath Extractor 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 JSONPath Extractor 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.

Preview access · not provider authentication

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

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