Navigate to the definition of a symbol at the given position. Returns file path, line, and column of the definition.

Navigate to the type definition of a symbol. Useful for finding the class/interface that defines a variable's type.

Find all references to the symbol at the given position across the workspace.

Find all implementations of an interface or abstract method.

Get hover information (type info, documentation) for the symbol at the given position.

Get function/method signature information when inside a call expression.

Get all symbols (functions, classes, variables, etc.) defined in a document.

Search for symbols across the entire workspace by name.

Get cached diagnostics (errors, warnings) for a file. Diagnostics come from language server notifications.

Get code completion suggestions at the given position.

Rename a symbol across the workspace. By default performs a dry run showing changes without applying them.

Get available code actions (refactorings, quick fixes) at a position or range. Use for automated fixes, imports organization, and refactoring operations.

Get the call hierarchy for a function/method - who calls this function (incoming) and what functions this calls (outgoing). Essential for understanding code flow and impact analysis before refactoring.

Get the type hierarchy for a class/interface - supertypes (parents, interfaces) and subtypes (children, implementations). Use for understanding inheritance and planning refactoring that affects class hierarchies.

Format a document using the language server's formatting capabilities. Respects project-specific formatting settings.

Comprehensive symbol search combining multiple LSP operations in one call. Get definition, references, implementations, type info, and call hierarchy for a symbol. More efficient than calling multiple individual tools.

Get status of running language servers.

Manually start a language server for a specific workspace.

Stop a running language server.
