Terraform

Tool Selection

• MCP tools (mcp__terraform): workspace listing, run management, provider/module registry lookups
• curl: plan and apply log retrieval — the MCP server does not expose these endpoints

Run Monitoring

Use MCP tools to find and inspect runs:

1. list_workspaces to find the workspace by name
2. list_runs with the workspace ID to see recent runs
3. get_run_details with the run ID for status, relationships, and timestamps

Run details include relationships.plan.data.id and relationships.apply.data.id — use these to fetch logs.

Fetching Plan/Apply Logs

The MCP server does not expose log retrieval; use the TFC API directly.

# Get the apply details (includes log-read-url)
curl -s \
  -H "Authorization: Bearer $TFE_TOKEN" \
  -H "Content-Type: application/vnd.api+json" \
  https://app.terraform.io/api/v2/applies/{apply-id} | jq -r '.data.attributes."log-read-url"'

Then fetch the raw logs from the archivist URL (no auth needed — pre-signed):

curl -s "$(archivist_url)"

The same pattern works for plans via /api/v2/plans/{plan-id}.

See [references/api.md](references/api.md).

Authentication

$TFE_TOKEN is sourced from:

• terraform login (stored at ~/.terraform.d/credentials.tfrc.json)
• Or set directly as an environment variable

The MCP server reads TFE_TOKEN from the environment. For curl calls, use it as a Bearer token.

Registry

Provider and module searches use MCP tools (search_providers, search_modules, provider_details, module_details). No curl needed.
