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 Language Proficiency Mapper.

  1. 01

    Check minimum requirements

    This capability checks if a specific CEFR level meets the language standards for a certain country or purpose. It returns a pass or fail status along with the required minimum level.

  2. 02

    Get cross exam equivalency

    This capability compares different language exams to find equivalent proficiency levels. Use it to see how a score on one test translates to another major exam based on a given CEFR level.

  3. 03

    Map exam score to cefr

    This capability converts a raw language exam score into its corresponding CEFR level from A1 to C2. It provides a direct mapping from specific test results to the standardized scale.

FAQ

Questions Language Proficiency Mapper owners ask.

  • 01

    Can I convert IELTS scores to CEFR?

    Yes. You can use the map_exam_score_to_cefr capability to turn an IELTS band score into a CEFR level.

  • 02

    How do I check if my score is enough for a visa?

    Once you have your CEFR level, you can use the check_minimum_requirements capability to see if it meets the standards for your target country.

  • 03

    Does this work with TOEFL and DELF?

    Yes, the MCP is designed to handle various exams including TOEFL, DELF, and others.

  • 04

    What is CEFR?

    CEFR is the Common European Framework of Reference for Languages, a standard used to describe language ability from A1 to C2.

  • 05

    Can I compare two different language exams?

    Yes, the get_cross_exam_equivalency capability allows you to see how different exam scores relate to one another.

  • 06

    What is the core function of this service?

    The primary function is to use the map_exam_score_to_cefr capability. You provide a raw score (e.g., IELTS band 7), and it converts that into the standardized CEFR level (B2). This mapping is critical for all subsequent checks.

  • 07

    How can I check if my score meets a university's minimum requirement?

    Use the check_minimum_requirements capability. Simply input your target country (e.g., Germany), the purpose (University Enrollment), and your current CEFR level. The system will tell you if you pass or fail against hardcoded policy rules.

  • 08

    I have a B2 score on IELTS; what does that mean for other exams?

    For cross-comparison, use the get_cross_exam_equivalency capability. You provide your primary exam and CEFR level (e.g., IELTS, B2), and it retrieves documented advisory equivalencies for other major tests like TOEFL or DELF.
