Which one, for what

Massed Compute E

Good for Agents that rent whole GPU VMs by the hour for training, fine-tuning or a model server and want a small MCP tool set with a read-only mode.

Ahead on

  • Agent ergonomics, 56 against 48
  • Security & auth, 61 against 51

Watch for

No status page, incident history or security.txt was found on any of the vendor's hosts

Thunder Compute C

Good for Agents in coding tools that rent a single persistent GPU machine for development, fine-tuning or a model server, at low hourly prices and over MCP.

Ahead on

  • Reliability, 65 against 20
  • Maintenance & community, 79 against 51

Also in its favour

  • No incidents deducted, where Massed Compute loses 5 points for them

Watch for

No rate limits, 429 guidance or SLA were found in the reviewed documentation, and the terms disclaim availability

Verdicts

Massed Compute

The hosted MCP server and REST API accept OAuth grants or API tokens in read-only and full-access tiers, and all 17 tools carry typed schemas and safety annotations in a public server card. No status page, rate limit figures or API changelog were found, a launch has no idempotency key, and the governing terms could not be read.

Thunder Compute

The hosted MCP server signs in with OAuth and separate read and write scopes, and the REST API has a public OpenAPI 3.1 document with keyless price and availability endpoints. No rate limits, SLA or API changelog were found, instance creation has no idempotency key, and instances cannot be stopped, only deleted.

Before you call either

Massed Compute

  1. Use https://vm.massedcompute.com/api/v1. The older docs at api-docs.massedcompute.com describe a separate marketplace API on api.massedcompute.com whose keys come from support.
  2. Ask the owner for a read-only token unless the task must launch or terminate. Read-only credentials cannot call launch, restart, terminate or SSH key changes.
  3. Call gpu_inventory_list and images_list before instances_launch. Product names and image IDs are free values, and SXM-only images do not run on PCIe cards.
  4. Expect 402 on launch until the owner has added credit and set a recharge amount and threshold. List instances before retrying a launch.
  5. Terminate to end billing. Stopping keeps the full hourly charge, and termination deletes the instance data.

Thunder Compute

  1. Call GET /v2/status or the get_availability tool before creating an instance. Availability can change before launch, and creation fails when a type is sold out.
  2. List instances before retrying a failed create, because the call has no idempotency key.
  3. Pass public_key on create. If omitted, the response carries a generated private key that is returned once.
  4. To pause work, create a snapshot, delete the instance and later create a new instance from the snapshot. Snapshot storage keeps billing until deleted.
  5. For headless use set TNR_API_TOKEN to a token from the console. The MCP server needs a browser sign-in on first connection.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
