What this server can do

8 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

authorize(workflow, operations, principal_arn)
Pre-flight authorization check for an AWS operation. Resolves the IAM actions the operation requires, then asks AWS's own policy simulator (SimulatePrincipalPolicy) whether the current role (or a given principal) allows them. Returns resolution (exact|partial|unresolved) and evaluation (allowed|denied|unknown) as separate fields. Requires AWS credentials; without them evaluation=unknown with the reason.
list_methods(service)
List all methods for a given library or service. Use after list_services to drill into a specific one. Required: service.
list_services
List all libraries and services that have verified method contracts. Use this first to discover what's available, then query for specific methods.
list_workflows
List the curated named workflows that can generate least-privilege IAM policies.
policy(workflow, operations, description)
Generate a least-privilege IAM policy for an AWS workflow. Pass a named workflow, explicit IAM actions, or a description. Returns the exact policy with confidence tier and any unresolved operations.
query(sig, limit, query, packages, error_type)
Search for verified method contracts for any library. Pass any text -- library name, method, what you're building, or an error you hit.
register(env, fix, error, action, symbol, library, version, error_class, receipt_sig)
Register a fix. Three actions: confirm (it worked), append_thread (variant worked), new_receipt (nothing matched, I fixed it). Required: action, library, symbol.
verify(policy, workflow, operations)
Feed a generated policy back to AWS's own policy evaluation engine (SimulateCustomPolicy) and confirm it grants exactly the intended operations and nothing extra. Returns verified (True|False|unknown), grants_all, grants_extra. Requires AWS credentials; without them verified=unknown with the reason. Wildcarded operations are expanded to concrete actions first.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
