MDEngine 0.6.3

Hosted GPU tier is now reachable over MCP from any HTTP-capable client, no install needed:

claude mcp add --transport http mdengine-cloud https://api.forcefieldsilicon.com/mcp --header "Authorization: Bearer mde_YOUR_KEY"

Tools: account, submit_job (deck inline), create_job/start_job, job_status, job_log, job_results, list_jobs, cancel_job. Discovery card at /.well-known/mcp/server-card.json. Registry listing com.forcefieldsilicon/mdengine now advertises the remote.

Local MCP bundle (macOS 14+, Apple silicon; Developer ID signed + notarized): mdengine-mcp-0.6.3-macos-arm64.mcpb, SHA-256 2f490de84f65ed553f6190ba55525daedec120490f9b1ff8549a8d5c7920ac06. Claude Desktop: open the file. Other clients: mcpb unpack and point at server/mdengine-mcp.

MDEngine 0.6.2

MCP server: tool titles + behaviour annotations; first MCP Bundle release and MCP Registry listing (com.forcefieldsilicon/mdengine).

Install the MCP server

• Claude Desktop: download mdengine-mcp-0.6.2-macos-arm64.mcpb and open it.
• Other clients: mcpb unpack mdengine-mcp-0.6.2-macos-arm64.mcpb dir then point the client at dir/server/mdengine-mcp (stdio), or use the tools tarball.
• SHA-256 of the .mcpb: d51e2ac7ce15c1f51060a5c5341e965426698933802fc23cd460e9ee1d20a72f

macOS 14+ (Apple silicon). Binaries are Developer ID signed (hardened runtime) and notarized.

Prebuilt lmp for the hosted GPU runner image. ADA89 = RTX 4090/L4/L40. Built on RunPod 2026-09-05 (GJOB-092). Consumed by docker/runner-gpu/Dockerfile.prebuilt via .github/workflows/runner-gpu.yml.

MDEngine 0.6.1

First notarized release — signed with Developer ID (Gitinama Inc.), notarized and stapled, so it opens on macOS 14+ without Gatekeeper warnings.

Asset	What it is
MDEngine-0.6.1.dmg	The app. Open, drag MDEngine to Applications. Signed, notarized, stapled.
mdengine-tools-0.6.1-macos-arm64.tar.gz	mdengine CLI + mdengine-mcp MCP server (Apple silicon). Signed + notarized (hardened runtime).

LAMMPS itself (brew install lammps) is needed only for running simulations, not for viewing trajectories.

What's new since 0.6.0

• Inspector ▸ Z-profile: numeric depth axis, labeled surface-plane marker, chart tooltip; Export CSV… / Export Excel… of the last frame
• Inspector toggle is now a full-size toolbar button
• MCP remote execution: declare hosts in ~/.mdengine/hosts.json, then submit_lammps host=…, list_hosts, fetch_job; explicit cancelled job state
• Release tooling: make_dmg.sh signs + notarizes + staples the DMG; new make_tools.sh packages the signed CLI + MCP server
