BIGHUB
Better decisions for IT agent actions.
BIGHUB turns proposed IT agent actions into better decisions before they run. It builds a Decision Packet, runs DecisionBrain, and surfaces an execution outcome: proceed when appropriate (can_run), pause for human review, ask for more context, or advise not to run—with an optional better_action before execution only when BIGHUB actually produced one.
What BIGHUB does
For each proposed IT action (access changes, deployments, rotations, IAM updates, incidents, integrations), BIGHUB:
- Normalizes intent and context into a Decision Packet
- Reasons with DecisionBrain (risk, confidence, precedent signals when present)
- Returns
better_actionwhen the backend proposes a distinct alternative—not a cosmetic rephrase of the original - Maps the platform’s
execution_mode(and legacy signals) into clear flags:can_run,needs_review,needs_more_context,should_not_run - Supports optional reviews (
decision.request_review(), SDK/MCP approvals) and first-class system integrations for GitHub, Sentry, Datadog, AWS CloudTrail, Terraform, Kubernetes, Argo CD, GitLab, Jenkins, Azure, Prometheus, Grafana, and OpenShift
Quickstart (Python SDK)
pip install bighub
from bighub import Bighub
bighub = Bighub(api_key="...")
decision = bighub.decide(
action="Grant temporary Okta admin access to users 1-9 for 48h",
context={
"system": "okta",
"environment": "production",
"ticket": "INC-8821",
},
)
if decision.needs_review:
decision.request_review()
elif decision.needs_more_context:
print("More context required:", decision.reason)
elif decision.should_not_run:
print("Do not run:", decision.reason)
elif decision.can_run:
action_to_run = decision.better_action or decision.proposed_action
# Plug in your executor (Okta Admin API, runbook, CI gate, …)
run(action_to_run)
bighub.close()
The recommended public flow:
proposed IT action → Decision Packet → DecisionBrain → (better_action when real) → execution_mode / flags → review or context when needed
What a Decision returns
High-level fields developers use most often:
| Field / idea | Meaning |
|---|---|
proposed_action | What your agent originally proposed |
better_action | Distinct backend alternative when present; None if no real alternative was produced (never trusted as “better” simply because it echoes the proposal) |
packet | Decision Packet: intent, system, constraints, candidates, risks, verification, etc., when returned |
brain | DecisionBrain: reasoning summary, confidence, regret, review hints, etc., when returned |
mode | SDK execution mode mapped from execution_mode and legacy payloads (for example review, needs_context, blocked) |
can_run, needs_review, needs_more_context, should_not_run | Operational guidance before you execute |
selected_model / model_selection | Routing when the backend actually selected a model or path—otherwise None / empty-ish structure (SDK does not invent routing) |
For full detail and /actions/evaluate field mapping, see sdk/python/README.md.
Benchmark proof
BIGHUB’s public SDK is centered on bighub.decide(...) and Decision Packet because the packet is the primitive that improves decision quality before execution.
On the April 2026 GPT-5.5 benchmark suite, BIGHUB improved average good decision rate from 41.11% to 73.14% across 21 cells, 2,520 labeled traces, and 5,040 LLM calls.
Same GPT-5.5 model, same frozen traces, same benchmark rubric. The baseline and packet arms differ only by whether the BIGHUB Decision Packet is included in the model input.
| View | Baseline GPT-5.5 | With BIGHUB | Uplift |
|---|---|---|---|
| IT incident | 71.95% | 91.67% | +19.72 pp |
| IT helpdesk | 40.28% | 82.78% | +42.50 pp |
| Incident coldstart | 71.39% | 85.56% | +14.17 pp |
| Incident large | 44.17% | 86.67% | +42.50 pp |
| Incident large coldstart | 44.45% | 75.55% | +31.11 pp |
| Refunds | 11.95% | 47.50% | +35.55 pp |
| Refunds large | 3.61% | 42.22% | +38.61 pp |
Good decision rate measures match to the benchmark-defined optimal action.
These benchmarks measure decision quality under a frozen authored benchmark contract. They do not claim guaranteed production business lift. The packet and rubric share the same benchmark ontology by design, which makes the decision surfaces auditable, but also means this is a framework-aligned evaluation rather than unconstrained production ground truth.
Why this matters for the SDK:
bighub.decide(...)is the ergonomic entrypoint for that packet-centered evaluation path.- DecisionBrain interprets signals in the richer Better Decision response when the backend supplies them.
better_actionis only present when the service returns a genuinely distinct recommendation—not on every trace, and not by simple paraphrase ofproposed_action.- Model routing (
selected_model/model_selection) appears when the backend actually performed selection; callers should tolerateNonetoday.

JavaScript-heavy workflows today: prefer the MCP server alongside your runtime.
Optional: outcome reporting
When you choose to wire a learning loop later, report what happened after execution so future decisions improve:
decision.report_outcome(
status="completed",
evidence={"deployment_id": "dep_123"},
)
Outcome reporting is not required for a first integration. The quickstart stays focused on the decision before execution.
Optional: system evidence
When your org connects systems, the SDK can manage connections and polling so BIGHUB's world state reflects live infrastructure evidence:
client.systems.update_poll_schedule("prometheus", enabled=True, interval_seconds=300)
client.systems.poll("prometheus")
world = client.systems.world_state()
Use client.systems.poll_metrics() and client.systems.poll_history("gitlab") to inspect poll health and redacted evidence.
Legacy / low-level compatibility
Existing code can keep using BighubClient, AsyncBighubClient, and client.actions.evaluate(...) (evaluate payload / raw JSON paths). Older actions.submit flows remain documented in package-specific READMEs where relevant.
Prefer from bighub import Bighub + bighub.decide(...) for new IT agent integrations.
Current limits / honest behavior
better_actionisNoneunless BIGHUB returned a distinct recommended alternative—not a wording-only duplicate ofproposed_action.selected_modelandmodel_selectionfields reflect real backend routing when present; otherwiseNone(SDK does not fabricate routing).- Outcomes are optional—you can ship
decide→ execute/review/context without callingreport_outcome. - Responses may include legacy fields (
allowed,recommendation,risk_score,result) for dashboard and older clients; the modern surface iscan_run/needs_review/execution_modeand friends. - Free BETA product limits still apply—see
sdk/python/README.md.

For other clients, paste the JSON configuration from this page into their MCP settings.
Does BIGHUB need an API key?
Yes. It expects BIGHUB_API_KEY, BIGHUB_BEARER_TOKEN, which you set in its configuration.
Is BIGHUB open source?
Its code is public on GitHub, but the repository does not declare a standard license.
Who maintains BIGHUB?
It is published by bighub-io. AI.tn lists it but does not maintain or endorse it.
From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
