Waiting for input…
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.

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.
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.
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.
01-03
3 capabilities in this set.
Part of 3 available through Tool Output Truncator.
- 01
Validate truncation integrity
This capability checks if a truncated string is still valid. It confirms the text respects your byte limits and hasn't corrupted any characters.
- 02
Calculate exact byte size
This capability measures the precise UTF-8 byte size of any string. Use it to get an exact count before sending data to your AI client.
- 03
Truncate tool output
This capability shrinks a string to fit a specific byte limit. It is designed to cut data safely without breaking multi-byte characters like emojis.
Real work
What teams actually run
Large Log Analysis
The agent trims massive log files to fit the context window before summarizing errors.
API Response Management
Your agent shrinks oversized JSON responses to prevent hitting token limits.
Data Cleaning
The AI uses byte measurement to prepare text for downstream processing.
Emoji-Heavy Text Processing
The agent safely truncates strings containing complex symbols without breaking them.
One connector, every AI
Tool Output Truncator 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.

Le ChatBuilding your own app? The connector is yours to use.
You don't need a client to put Tool Output Truncator 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.

Connect your client
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 Tool Output Truncator, so you can see the experience inside your AI.
It does not authenticate your account with Tool Output Truncator. 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 Tool Output Truncator owners hand off.
This is for developers and power users building agents that interact with large external datasets.
- 01
AI Engineers
They use it to manage context window constraints during agentic workflows.
- 02
Data Analysts
They hand off large datasets to an AI client and need to trim them for processing.
- 03
Automation Developers
They build workflows where capability outputs must stay within specific technical limits.
FAQ
Questions Tool Output Truncator owners ask.
- 01
Will this break my emojis?
No. The truncation capability is specifically designed to handle multi-byte characters so emojis and special symbols remain intact.
- 02
How is this different from standard text cutting?
Standard cutting often splits characters in half, causing errors. This MCP uses UTF-8 aware logic to ensure byte limits are met without corrupting data.
- 03
Which AI clients can use this MCP?
You can use this with any MCP-compatible client, including Claude, Cursor, and Windsurf.
- 04
Do I need to host this myself?
No. Vinkius hosts and manages the MCP for you. You just connect and start using the capabilities.
- 05
Can I verify if the truncation worked correctly?
Yes. You can use the validate_truncation_integrity capability to confirm the output respects limits and preserves character integrity.
- 06
How does this prevent character corruption?
The truncate_tool_output capability identifies the exact byte boundaries of UTF-8 characters. If a truncation would split a multi-byte character, the capability backtracks to the start of that character sequence, ensuring the resulting string remains valid.
- 07
Why use byte size instead of character count?
LLM context windows are limited by tokens and bytes, not just character counts. Since a single character can occupy multiple bytes in UTF-8, using calculate_exact_byte_size provides the most accurate way to manage the actual data footprint.
- 08
Can I verify if a truncation was successful?
Yes, you can use the validate_truncation_integrity capability to check if the processed content respects the byte limit and maintains character integrity.
