Primary tools included: Lifecycle management of LocalStack runtime with authentication, Automatic detection and deployment of infrastructure as code projects, Natural language search of LocalStack documentation and guides.
Gateway between LLM agents and world data through eight tools and a bundled endpoint catalog.
A MCP server for LocalStack to manage local AWS environments, including lifecycle operations, infra deployments, log analysis, fault injection, and state management.
One-step: find best endpoint for a natural-language query and call it. Combines search + call in one round trip.
search_endpoints
Search the bundled endpoint catalog. Runtime search does not fetch `/openapi.json`.
describe_endpoint
Inspect an endpoint by `operation_id`, including path, method, parameters, required inputs, `agent_hints`, and `request_body_schema` for JSON-body POST operations.
call_endpoint
Call a Sugra API operation by `operation_id`. Arbitrary path calls are no longer supported.
list_toolsets
List catalog groups with endpoint counts and descriptions.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Sugra API is categorized under Cloud Platforms and uses a local stdio subprocess. In contrast, Localstack Mcp Server belongs to Cloud Platforms using local stdio subprocess. Select Sugra API when you need capabilities focused on cloud platforms and Localstack Mcp Server when you require tools for cloud platforms.
Screen a name against sanctions and watchlists (Sugra Entity).
sugra_entity_lookup
Composed entity lookup by identifier - `anchor` is `lei` or `vat`, plus the identifier `value`; returns registry identity + screening (Sugra Entity).
resolve_entity
Free text (ticker, company, indicator, coin, currency pair) to a canonical market or macro entity. Ambiguous matches return ranked candidates, never a silent pick.
get_snapshot
Entity plus a named recipe to one composed current view with freshness, provenance, coverage, and billing blocks. Composed calls charge a fixed recipe cost (1-2 requests) from the daily quota.
get_timeseries
Entity plus metric (`price`, `macro_series`, `etf_flows`) to a bounded series with an explicit downsampling flag.
