Hosted GPU runs for MDEngine. Every tool except this handshake needs a credential: sign in through OAuth (paste your API key once) or send `Authorization: Bearer mde_...` (key from a credit pack at https://forcefieldsilicon.com/mdengine). Typical flow: account -> submit_job (inline deck) -> job_status/job_log until done -> job_results.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 12 tools

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

account auth-required 3h ago
Balance in USD, how jobs are priced (`pricing.mode` job = the deck's own work in atom-steps at per-class prices, capped at wall_limit_s x rate; metered = per second of pod time), the rate table, and the key id of the API key in use.

mcp-tool
{ "type": "object", "properties": {} }
arguments 4 lines

list_jobs auth-required 3h ago

Jobs of this API key, newest first. Compact rows (id, state, label, created, finished, gpu, cost_usd, error) unless full=true.

  }

arguments 13 lines

submit_job auth-required never probed

One call: create a hosted GPU job, upload the deck given INLINE as {relative_path: text}, and queue it. Total inline size <= 8 MB; for larger decks use create_job, PUT the tarball to upload_url, then start_job. Billing starts at the first heartbeat (state running) and stops at done/failed/cancelled. The deck is executed as a program on an isolated GPU pod.

cancel_job auth-required never probed
Cancel a job that is not finished. A running job is billed up to the cancel time; its pod is terminated.

mcp-tool
{ "type": "object", "required": [ "id" ], "properties": { "id": { "type": "string", "description": "Job id, e.g. MDJOB-20260907-3F200C" } } }
arguments 12 lines
start_job auth-required never probed
Step 2: queue a job whose deck tarball has been uploaded. A GPU pod is launched; billing starts when it reports running.

mcp-tool
{ "type": "object", "required": [ "id" ], "properties": { "id": { "type": "string", "description": "Job id, e.g. MDJOB-20260907-3F200C" } } }
arguments 12 lines
job_log auth-required never probed
The last <= 20 thermo/log lines the running pod reported (30 s heartbeat). Full log.lammps is in the results tarball.

mcp-tool
{ "type": "object", "required": [ "id" ], "properties": { "id": { "type": "string", "description": "Job id, e.g. MDJOB-20260907-3F200C" } } }
arguments 12 lines
capabilities auth-required 3h ago
Capability manifest of the hosted runners: LAMMPS version, installed packages, and every style by category with gpu=true (KOKKOS-accelerated) or gpu=false (exists, but runs on the pod's CPU cores at the GPU rate). Default = compact summary; runner=lammps&full=true returns the whole style table. Use preflight_deck to check a specific deck.

mcp-tool
{ "type": "object", "properties": { "full": { "type": "boolean", "description": "Include the full style table (large)" }, "runner": { "type": "string", "description": "lammps | openmm; omit for all" } } }
arguments 13 lines

create_job auth-required never probed

Step 1 of the two-step path for big decks: validates the spec, reserves a job id, returns a presigned upload_url. PUT the deck as a .tar.gz (<= 2 GB, relative paths, input at `input`) to upload_url, then call start_job.

mcp-tool

{
  "type": "object",
  "required": [
    "input"
  ],
  "properties": {
    "gpu": {
      "type": "string",

    },

    }
  }
}

arguments 36 lines

job_status auth-required never probed
State (created|uploaded|queued|launching|running|uploading|done|failed|cancelled), GPU, rate, billed seconds, cost so far, exit code, error, last thermo lines.

mcp-tool
{ "type": "object", "required": [ "id" ], "properties": { "id": { "type": "string", "description": "Job id, e.g. MDJOB-20260907-3F200C" } } }
arguments 12 lines
job_results auth-required never probed
For a done/failed job: a presigned download_url (valid ~7 days) for the results tarball (work/, log.lammps, exitcode). Results are deleted 30 days after the run.

mcp-tool
{ "type": "object", "required": [ "id" ], "properties": { "id": { "type": "string", "description": "Job id, e.g. MDJOB-20260907-3F200C" } } }
arguments 12 lines
delete_results auth-required never probed
For a finished job: delete its deck and results tarballs immediately instead of at the automatic 30-day purge. Metadata and billing records are kept; results can no longer be downloaded.

mcp-tool
{ "type": "object", "required": [ "id" ], "properties": { "id": { "type": "string", "description": "Job id, e.g. MDJOB-20260907-3F200C" } } }
arguments 12 lines
preflight_deck auth-required never probed
Dry run of the check submit_job performs: which styles the deck asks for are MISSING on every hosted LAMMPS image (the run would exit at startup), which are CPU-only, whether its pair style will use the GPU at all, and which image (`runner`) the job will be routed to — decks needing packages beyond the fast default image run on lammps-full automatically. Nothing is created or billed.

mcp-tool
{ "type": "object", "required": [ "input", "files" ], "properties": { "files": { "type": "object", "description": "Deck contents {path: text}, must include `input`", "additionalProperties": { "type": "string" } }, "input": { "type": "string", "description": "Relative path of the LAMMPS (or runner) input script inside the deck, e.g. in.lmp" } } }

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/9b665457e9936f44/badge.svg)](https://brick.blue/agent/9b665457e9936f44)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
