nomad-mcp
Exposes a HashiCorp Nomad cluster as MCP tools for AI agents, enabling read-only inspection of jobs, allocations, nodes, and deployments, with optional write operations like stopping jobs, scaling task groups, restarting allocations, and registering jobs.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
list_jobsList Nomad jobs, optionally filtered by name prefix and namespace.
get_jobGet the full spec and status of a single Nomad job by ID.
get_job_allocationsList allocations belonging to a job.
get_job_deploymentsList deployments for a job.
get_job_evaluationsList evaluations for a job (useful for diagnosing why a job isn't placing).
get_allocationGet details of a single allocation, including task states and events.
get_allocation_logsFetch recent stdout/stderr log output for a task in an allocation.
list_nodesList client nodes in the Nomad cluster.
get_nodeGet details of a single Nomad client node, including allocations and resource usage.
list_deploymentsList recent deployments across the cluster.
get_deploymentGet details of a single deployment.
list_namespacesList Nomad namespaces.
stop_jobStop a Nomad job. Set purge=true to also remove it from Nomad's state entirely (cannot be undone via job history).
scale_task_groupScale a task group within a job to a specific count.
reschedule_allocationStop a single allocation, causing Nomad to reschedule it as a brand-new allocation (possibly on a different node). This is Nomad's DELETE-equivalent /stop call, not an in-place restart — use restart_allocation if you want the same allocation's tasks restarted in place.
restart_allocationRestart task(s) within a single allocation in place (same allocation ID, same node) — the direct equivalent of `nomad alloc restart`. Pass task to restart just one task, or omit it to restart all tasks in the allocation.
register_jobSubmit (create or update) a Nomad job. Accepts either a full Nomad job spec in HCL (jobHcl) or JSON (jobJson).

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
17/17 tools missing one or more hints — list_jobs (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_job (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_job_allocations (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +14 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
15/17 tool handlers declare input schemas (88%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/17 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 5 high severity in production deps — @modelcontextprotocol/sdk@1.0.4 (high), undici@6.19.8 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
