🧠 NeuroForge — Live AI Bridge for Luau Runtime Instrumentation

Think of NeuroForge as a radio antenna bolted onto a running Roblox experience. Instead of shouting commands into the void and waiting for a rebuild cycle, you tune into the frequency of a live session — AI assistants on one side, an instrumented Luau runtime on the other — and the conversation flows in both directions, in real time, under strict identity and permission rules.

NeuroForge is a Model Context Protocol (MCP) server that gives AI coding companions (Claude, Cursor, or any MCP-compatible client) a structured, auditable doorway into a running Roblox Luau environment. It pairs with a whitelist-oriented execution platform so that every code submission, every inspection request, and every returned value is bound to a verified participant and a scoped capability grant.

No guesswork. No blind pasting. Just a disciplined, observable bridge between the model that thinks and the runtime that runs.

🚀 What NeuroForge Actually Is

Most developer tooling treats a game session as a black box: you write code, you deploy, you hope, you squint at logs. NeuroForge flips that posture. It turns the live Luau session into a queryable, scriptable surface — but only through the narrow pipe the operator has deliberately opened.

Under the hood, NeuroForge is three cooperating layers:

1. The MCP Face — a protocol-compliant server that exposes tools, resources, and prompts to AI assistants. This is the part your assistant "sees."
2. The Relay Spine — a transport-agnostic message channel that ferries requests from the server to enrolled runtime agents and returns structured results. It is designed to be resilient to latency spikes and partial failures.
3. The Runtime Instrumentation Kit — a Luau-side library that loads into a permitted session, registers handlers, enforces the local policy, and reports back with typed payloads.

Each layer is replaceable. Each layer is observable. Each layer can be locked down.

📦 Getting the Project Onto Your Machine

Because distribution happens through a curated release channel, the binary and its companion Luau instrumentation bundle are pulled together. Verify the integrity manifest before first launch — NeuroForge refuses to attach to a runtime if the manifest does not match.

After acquisition, the expected layout on disk is:

• /app — the MCP server entry point and its adapter modules
• /runtime — the Luau instrumentation kit to be staged into the target environment
• /policy — default capability matrices and identity descriptors
• /logs — rolling structured event journals

Configuration lives in a single neuroforge.toml file at the repository root. Sensitive values are referenced by environment indirection rather than inlined — never commit raw credentials to this file.

💡 Why This Exists

Writing Luau for a live product is a peculiar craft. The language is expressive, the runtime is generous, but the loop between "I have an idea" and "the idea is validated against a real session" is historically long and lossy. Developers improvise: they sprinkle print statements, they rebuild, they lose the thread of what they were testing.

NeuroForge compresses that loop without collapsing the safety net. It assumes two truths simultaneously:

• The assistant is a powerful collaborator and deserves direct, structured access to the runtime.
• The runtime is a production surface that must never be treated casually.

The result is a tool that feels like a probe in one hand and a leash in the other.

🛰️ Feature Constellation

• Session-Aware Tool Surface — tools exposed to the AI client are generated from the live capability manifest, so unavailable actions are never suggestible.

• Identity-Bound Execution — every submitted snippet carries the identity of the requester; the runtime validates the identity before evaluating a single token.

• Structured Result Contracts — returned values are typed and versioned, so the assistant never has to guess whether a payload is a table, a function handle, or a serialized trace.

• Deterministic Replay Hooks — capture a sequence of operations and replay them against a prepared bench session for regression work.

• Composable Capability Sets — grants are additive tokens that can be nested, revoked, or time-boxed without restarting the server.

• Graceful Degradation — if the runtime link drops, NeuroForge surfaces a clear status to the assistant rather than hanging or fabricating output.

• Multi-Client Multiplexing — several assistants can share a single enrolled runtime, each isolated by their own capability set.

• Language-Neutral Payloads — the wire format is compact and language-independent, so adapters for additional AI frontends are straightforward to add.

• Audit-Ready Journals — every accepted and rejected operation is logged with a correlation identifier.

• Zero-Surprise Defaults — the out-of-the-box policy grants inspection only; execution privileges must be explicitly enabled.

🏗️ Architecture Walkthrough

The MCP face speaks a well-known protocol to the assistant. When the assistant asks to run something, the request is normalised into an internal operation envelope. That envelope carries:

• a correlation identifier,
• the originating identity,
• the requested capability,
• the payload,
• and an expiry.

The relay spine then hands the envelope to the matching runtime agent, which performs local policy checks, evaluates against the sandbox, and returns another envelope. Errors are first-class: they are encoded as structured results rather than thrown across the boundary.

If you imagine a river with locks and gates, the relay spine is the lockkeeper. It does not decide what boats may pass — that is the policy engine's role — but it does decide when and how they pass.

🔐 The Permission Model

NeuroForge embraces a principle we like to call earned reach. Nothing happens because the assistant guessed it could happen. Everything happens because an operator granted it, an identity proved it, and the runtime confirmed it.

The model has three tiers:

1. Enrollment — an identity is registered with the server and assigned a baseline capability set.
2. Grant — additional capabilities are attached, optionally with a validity window and an attached purpose label.
3. Revocation — capabilities can be withdrawn at any moment; the next operation from that identity will simply fail closed.

This is not a padlock bolted on afterward. It is the frame the whole structure is built around.

🧩 Capability Scopes Explained

• inspect.environment — read structural facts about the live environment without touching state.
• inspect.values — retrieve the current value of named references, subject to privacy filters.
• execute.dry — evaluate expressions that are guaranteed side-effect free.
• execute.scoped — evaluate statements within a designated namespace.
• execute.extended — a broader grant intended for benches and pre-release environments.
• subscribe.events — receive a stream of runtime events as they occur.
• replay.capture — record a sequence for later reproduction.

Capabilities compose. execute.scoped without inspect.values, for instance, lets a script change things but not observe them — a combination useful for stress exercises.

🌍 Multilingual & Accessibility Posture

The MCP face renders human-readable strings in multiple languages, with English as the fallback. Localization bundles are plain text so they can be reviewed and revised without touching logic.

The interface layer leans on semantic structure rather than visual trickery: labels are associated with their controls, contrast is generous, and animations are optional. Assistants are not the only readers of these surfaces — humans occasionally want to look over the shoulder too.

To add a language, drop a bundle into the localization directory. The server negotiates the best match from the client's declared preferences.
