get-datasource-docs
Get detailed documentation for a specific OpenTofu data source by provider namespace, provider name, and data source name.
LABSCO SUMMARY
Argument names come from the registry rather than from memory.
Resource and data-source documentation is fetched per version, so what gets written matches the provider you have pinned instead of whatever was current when the model was trained. Search takes the simple name — the 'terraform-provider-' prefix is dropped rather than required.
What it is
A client for the OpenTofu Registry: one search across providers, modules, resources and data sources, plus detail and documentation lookups for each of them.
What you get
- The registry searched by plain term, narrowed by type to providers, modules, resources or data sources
- Provider details by namespace and name
- Module details by namespace, name and target
- Documentation for a named resource under a provider, at a version you specify
- Documentation for a data source the same way
Requirements
npx on your PATH. No account and no key.
Setup effort
One command — npx -y @opentofu/opentofu-mcp-server
USE CASES
01
Writing a resource block for a provider you have not used before
Search by the plain name, then read the resource's documentation at the version you have pinned rather than the one the model remembers.
02
Choosing between modules that claim to do the same thing
Module details come back per namespace, name and target, which is what distinguishes two modules with the same short name.
03
Checking what a provider version actually offers
Provider details list what is there; data-source documentation covers the half of a provider that resource docs do not.
5 tools
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
get-module-details
Get detailed information about a specific OpenTofu module by namespace, name, and target. Use the simple module name, NOT the full repository name.
get-provider-details
Get detailed information about a specific OpenTofu provider by namespace and name. Do NOT include 'terraform-provider-' prefix in the name.
get-resource-docs
Get detailed documentation for a specific OpenTofu resource by provider namespace, provider name, and resource name.
search-opentofu-registry
Search the OpenTofu Registry to find providers, modules, resources, and data sources. Use simple terms without prefixes like 'terraform-provider-' or 'terraform-module-'.
