ASTRA — Unified Research Lab + MCP Server

Autonomous Sentient Thoughtful Reasoning Agent

Production-grade Model Context Protocol server exposing the ASTRA bio-hybrid neuromorphic simulation pipeline to AI assistants. Built with the official @modelcontextprotocol/sdk, it integrates a layered SNN LIF+STDP engine, consciousness proxy assessment, bio-computing platform telemetry, and an IRB ethics monitor — all queryable as MCP tools, resources, and prompts from Claude Desktop, Cursor, VS Code, and any MCP-compatible client.

🆕 v2.7 — Closed loop on a real LIF SNN

ASTRA v2.7 closes the active-inference actuation loop through a real spiking network: the chosen action injects sustained current into an SNNEngine whose firing rate (verified to respond monotonically to injection) becomes the grounded observation via adaptive normalisation. A temporal credit-assignment fix (B credits the action that caused each transition — corrected identically in TS and the NumPy reference, golden regenerated, equivalence preserved) plus annealed exploration let the controller learn to raise the substrate above the open-loop baseline (verified aggregate test). golden:check is now git-independent. Closed loop is functional-but-experimental: modest, noisy margin; actuation current[] not yet wired to the production SNN. See SECOND-ORDER-LOOP-INTEGRATION.md.

🆕 v2.2 — the_consciousness_ai (ACM) Integration

ASTRA v2.2 integrates tlcdv/the_consciousness_ai — the Artificial Consciousness Module research codebase — at two levels:

• Native TypeScript port (src/engine/tcai/): Global Neuronal Workspace with sigmoid ignition & reverberation, Kuramoto/AKOrN oscillatory binding, PAD emotional processing & reward shaping, attention-gated emotional memory, self-representation core + attention schema, and a metrics suite (GNW · Effective Information · Φ̃-RIIU) — all fed live from the SNN/world-model state and exposed as 8 new MCP tools (tcai_cycle, tcai_workspace_state, tcai_emotion_appraise, tcai_memory_store, tcai_memory_retrieve, tcai_self_model, tcai_metrics, tcai_reset).
• Full vendored Python codebase (python/the_consciousness_ai/, 215 files): the complete upstream ACM project for reference and PyTorch-based reproduction.

See TCAI-INTEGRATION.md for the complete Python → TypeScript mapping and architecture coupling. All consciousness-related metrics remain computational proxies, not measurements.

🆕 v2.2 — FinalSpark NeuroPlatform v2 Integration

ASTRA v2.2 also integrates the FinalSpark NeuroPlatform v2 wetware control API — the closed-loop interface to living neural organoids on a 128-electrode MEA — at two levels:

• Native TypeScript port + biophysical simulator (src/engine/neuroplatform.ts): faithful port of the NeuroPlatform controller surface (StimParam with charge-balance checking, IntanController, TriggerController, DatabaseController, CameraController) backed by a seeded OrganoidMEA model — exposed as 9 new MCP tools (np_status, np_configure_stim, np_send_trigger, np_count_spikes, np_query_spike_count, np_query_spike_events, np_query_triggers, np_camera_capture, np_closed_loop). The MEA's 128 electrodes couple one-to-one with the ASTRA SNN's 128 neurons.
• Live Python bridge (python/neuroplatform/astra_np_bridge.py): runs a homeostatic closed loop against the physical platform via the genuine neuroplatformv2 SDK, streaming couplings to ASTRA over JSON-RPC.
• Standalone dashboard (dashboard/ASTRA-NeuroPlatform-Dashboard.html): live MEA raster, spike scope, StimParam editor with charge-balance readout, trigger generator and closed-loop telemetry.

See NEUROPLATFORM-INTEGRATION.md for the complete API → TypeScript mapping. With no hardware attached the server runs in simulate mode (deterministic biophysical model), not living-tissue measurements.

Note on data mode: In the default sim mode, all bio-platform data is synthetically generated. The server is designed to connect to live platforms in live mode, but this requires hardware access and appropriate IRB approval.

What's New in v2

• Layered SNN architecture: Configurable feed-forward + recurrent topology (default: 32→64→16→16 = 128 neurons) replacing the flat random network
• Event-driven STDP: O(spikes × fan-out) instead of O(N²) per timestep
• Ring buffer: O(1) spike history eviction replacing O(n) Array.shift()
• Sparse weight storage: Adjacency lists instead of dense N×N matrix
• Honest ACM naming: Proxies clearly labelled as integrationProxy, broadcastProxy, arousalProxy with methodological basis strings — no false IIT/GWT/PAD claims
• Bounds-checked parameters: set_parameter rejects implausible values (NaN, Infinity, out-of-range)
• Mode-aware ethics: Reports distinguish simulated vs live data with explicit disclaimers
• CI pipeline: GitHub Actions for build, test, and Docker smoke-test
• Repo hygiene: dist/ excluded from VCS, .gitignore added, deployment script removed

Extracted to separate repositories: The v1 HTML dashboard (4 669 lines) and the legacy Node.js bridge config have been removed from this repo to keep it focused on the MCP server. See ASTRA-Unified-ResearchLab-MCP- for the original dashboard.

SNN Engine

Layered LIF+STDP — Configurable layered architecture. Default: 32 (input) → 64 (hidden_1) → 16 (hidden_2) → 16 (output) = 128 neurons.

Connectivity: feed-forward between adjacent layers (30%) + sparse recurrent within layers (10%). Weights stored as sparse adjacency lists, not dense matrices.

Biophysical parameters: τ_m = 20ms, V_th = −50mV, V_reset = −70mV, refractory = 2ms. Background noise range [10, 22] mV produces ~2 spikes/step at steady state with all neurons active. STDP: A+ = 0.01, A− = 0.012, τ± = 20ms, event-driven (processes only spiking neurons per timestep).

The SNN topology resource (astra://snn/topology) dynamically reports the actual engine configuration, including layer sizes, synapse count, connectivity parameters, and weight storage type (Map-indexed sparse adjacency lists).

ACM — Consciousness Proxy Module

⚠ Methodological disclaimer: The metrics below are computational proxies inspired by the referenced theories. They are not faithful implementations. See source code comments for full details.

Composite score: ACM = α·Φ̃ + β·GW̃ + γ·PAD̃ (default: α=0.40, β=0.35, γ=0.25)

Component	Basis	Inspired by	What it actually measures
integrationProxy (Φ̃)	Active fraction + mean firing rate + synaptic heterogeneity	IIT (Tononi)	Network participation and complexity proxy. True Φ is NP-hard to compute.
broadcastProxy (GW̃)	Cross-layer firing rate synchrony (CV-based)	GWT (Baars)	Uniform activation across layers. Does not model competitive coalitions or ignition.
arousalProxy (PAD̃)	Spike rate + bio coupling + energy	PAD (Mehrabian)	Arousal dimension only. Pleasure and Dominance are not computed.

Ethics IRB Monitor

IRB compliance level N3 (100K–1M neurons). Four biomarkers with three-state classification.

Mode-aware: In sim mode, reports include explicit disclaimers that data is synthetic and irbRequired is false. In live mode, DISTRESS triggers mandatory IRB notification.

Biomarker	Normal	Stress	Critical
Cell viability	≥ 90%	80–90%	< 80%
Firing rate	15–45 Hz	outside range	≤ 5 or ≥ 60 Hz
ATP/ADP	≥ 3.0	2.0–3.0	< 2.0
Calcium	< 100 nM	100–200 nM	≥ 200 nM

Parameter Bounds

The set_parameter tool validates all numeric inputs against a bounds registry to prevent injection of absurd values (negative percentages, Infinity, NaN). Bounds are defined per parameter path — see src/engine/state.ts for the complete registry.

Scaling Notes

The default 128-neuron configuration is designed for interactive demonstration. To scale toward the aspirational 256→512→256→128 (1 152 neurons) architecture:

1. Pass custom layers to SNNEngine: new SNNEngine({ layers: [{ name: 'input', size: 256 }, ...] })
2. Event-driven STDP scales as O(spikes × average fan-out), not O(N²)
3. Map-indexed adjacency lists provide O(1) weight lookup per synapse
4. Sparse storage keeps memory proportional to actual synapses (~18 KB at 128 neurons vs 64 KB dense)
5. Consider increasing intervalMs in the simulation loop for larger networks
6. For >10K neurons, a Rust/WASM or Lava SDK backend is recommended
