Struct PathfinderServer 

pub struct PathfinderServer { /* private fields */ }

The main Pathfinder MCP server.

Holds shared workspace state and dispatches MCP tool calls.

Implementations

impl PathfinderServer

pub async fn new( workspace_root: WorkspaceRoot, config: PathfinderConfig, ) -> Self

Create a new Pathfinder server backed by the real Ripgrep scout, Tree-sitter surgeon, and LspClient for LSP operations.

Zero-Config language detection (PRD §6.5) runs synchronously during construction. LSP processes are started lazily — only when the first LSP-dependent tool call is made for a given language.

If Zero-Config detection fails (e.g., unreadable workspace directory), the server falls back to NoOpLawyer and logs a warning. All tools remain functional in degraded mode.

pub fn with_engines( workspace_root: WorkspaceRoot, config: PathfinderConfig, sandbox: Sandbox, scout: Arc<dyn Scout>, surgeon: Arc<dyn Surgeon>, ) -> Self

Create a server with injected Scout and Surgeon engines (for testing).

Uses a NoOpLawyer for LSP operations — keeps existing tests unchanged.

pub fn with_all_engines( workspace_root: WorkspaceRoot, _config: PathfinderConfig, sandbox: Sandbox, scout: Arc<dyn Scout>, surgeon: Arc<dyn Surgeon>, lawyer: Arc<dyn Lawyer>, ) -> Self

Create a server with all three engines injected (for testing with a MockLawyer).
