Compatible with every major AI agent and IDE
What is the Statistics Engine MCP Server?
Large Language Models often struggle with complex statistical aggregations and dataset analysis, leading to subtle analytical errors. The Statistics Engine MCP Server eliminates this risk by equipping your autonomous agents with a highly optimized, local JavaScript computational core.
The Superpowers
- Flawless Data Analysis: Calculate mean, median, mode, standard deviations, and percentiles with 100% mathematical certainty.
- Absolute Data Privacy: Your sensitive business metrics, financial datasets, or user telemetry never leave your local infrastructure. Zero API calls.
- Zero Latency Engine: Process data arrays instantaneously within the local environment without network overhead.
Stop trusting LLMs to do math on arrays. Equip your agent with a real, deterministic statistical engine.
Built-in capabilities (5)
Calculates the mathematical mean (average) of a dataset
Calculates the median (middle value) of a dataset
It returns an array of numbers. Calculates the mode (most frequent value) of a dataset
Calculates the k-th percentile of a dataset
Calculates the population standard deviation of a dataset
Why OpenAI Agents SDK?
The OpenAI Agents SDK auto-discovers all 5 tools from Statistics Engine through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries Statistics Engine, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

Statistics Engine in OpenAI Agents SDK
Statistics Engine and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Statistics Engine to OpenAI Agents SDK through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

| Infrastructure | Self-hosted | Sandboxed V8 isolates |
| Credential handling | Plaintext in config | Vault + runtime injection |
| Data loss prevention | None | Configurable DLP policies |
| Kill switch | None | Global instant shutdown |
| Financial circuit breakers | None | Per-server limits + alerts |
| Audit trail | None | Ed25519 signed logs |
| SIEM log streaming | None | Splunk, Datadog, Webhook |
| Honeytokens | None | Canary alerts on leak |

Why teams choose Vinkius for Statistics Engine in OpenAI Agents SDK
The Statistics Engine MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 5 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
Statistics Engine for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the Statistics Engine MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Why use this instead of asking the AI to analyze the dataset directly?
AIs hallucinate complex data calculations because they generate text, not numbers. This MCP provides the AI with a deterministic tool, forcing it to offload the actual number-crunching to a strict JavaScript engine.
Is my data sent to any external service?
No. The entire engine runs completely local in your local environment. It is "Privacy First" by design, requiring no external APIs or network access.
How does the percentile calculation work?
The tool sorts your dataset and uses a robust interpolation method to find the exact boundary value below which a given percentage of observations fall. Perfect for p95 or p99 SLA reporting.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
