Which one, for what

Render MCP Server B

Good for Agents that deploy and debug applications on Render, reading logs and metrics and querying Postgres.

Also in its favour

  • A hosted endpoint, with nothing to install
  • No incidents deducted, where Terraform MCP Server loses 3 points for them

Watch for

No scopes and no read-only mode. An API key reaches every workspace its owner belongs to, and a read-only toolset request has been open since 8 October 2025.

Terraform MCP Server BB

Good for Agents writing or reviewing Terraform that need the real provider schema, and for teams on HCP Terraform who want plan and run inspection from chat.

  • Security & auth, 65 against 58
  • Payments & pricing, 60 against 40
  • Maintenance & community, 78 against 56

Also in its favour

  • Agent-ready, a grade of BB or better

Watch for

Workspace updates, variable writes, team membership and access grants run without the operations flag

Verdicts

Render MCP Server

A hosted server with 26 typed and annotated tools, OAuth or API key access and Apache-2.0 source. It cannot delete resources and wraps SQL in a read-only transaction. There are no scopes and no read-only mode, a key reaches every workspace its owner belongs to, and Render's status page recorded several major incidents in 90 days.

Terraform MCP Server

Nine registry tools load by default and need no credentials. Workspace updates, variable writes, team membership and access grants run without the operations flag.

Before you call either

Render MCP Server

  1. Pass workspaceId on every resource tool call. Session-based workspace selection through select_workspace is deprecated and scheduled for removal.
  2. Do not call trigger_deploy after pushing to a service with autoDeploy on. The push already starts a deploy.
  3. Use an API key in the Authorization header for CI. OAuth grants expire and need a person to approve the browser flow again.
  4. update_environment_variables merges by default. Set replace to true only to overwrite the whole set.
  5. Expect 429 from the Render API at 20 service creations an hour and 10 deploys a minute per service. Back off with jitter.

Terraform MCP Server

  1. Call search_providers first to get a provider_doc_id, then get_provider_details for that one document
  2. Pass the token in the Authorization header in HTTP mode. A TFE_TOKEN query parameter gets a 400
  3. Run whoami or get_token_permissions before writes to see what the token can do
  4. Check the workspace lock before create_run. A locked workspace returns an error naming force_unlock_workspace
  5. Pin the image tag (1.3.0), not latest, in scheduled jobs

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.
