VS Code Extension

The Travsr VS Code extension brings the code graph directly into your editor, status bar, code lenses, hover cards, and a full sidebar of panels.

Install

ext install travsr.travsr-vscode

Or search "Travsr" in the Extensions panel.

Also available on Open VSX for VSCodium and compatible editors.

Binary auto-install

If the travsr binary is not found on PATH, the extension shows a notification with a Download Binary button. Clicking it downloads the correct platform binary from GitHub Releases and places it on your PATH. No npm required.

To use a binary you already have at a custom path, set travsr.binaryPath in settings.

Status bar

The status bar item shows the current graph state. Click it to open the Graph Stats panel.

Indicator	Meaning
Travsr · connecting (spinning)	Extension is connecting to the daemon
Travsr · fresh · 18.4k nodes (green)	Graph is up to date
Travsr · indexing… (spinning)	Reindex in progress
Travsr · stale · 5m ago (amber)	Graph has not been updated since the last commit
Travsr · disconnected (red)	Daemon is unreachable

Sidebar panels

The Travsr activity bar icon opens the sidebar, which has two tree views, Travsr Graph and Repo Files. Every panel below is also reachable from the command palette.

Panel	Command	Description
Graph	Travsr: Show Graph	Visual Cytoscape.js graph for a symbol
Repo Files	(Repo Files view)	Hierarchical tree of every indexed file; see Repo Files Panel
Context Explorer	Travsr: Open Context Explorer	get_context results as a panel; see Context Explorer
Ask Symbol	Travsr: Ask Symbol	FTS search across all indexed symbols
Synonyms	Travsr: Manage Synonyms	Add and edit query-time synonym pairs
Languages	Travsr: Languages	Indexed languages and available language tools
Repos	Travsr: Registered Repos	All repos in the Travsr registry
Graph Stats	Travsr: Graph Stats	Node count, edge count, DB size, last indexed

Code lens

Every function, method, and class definition shows a blast radius code lens, the number of files that would be affected if that symbol changed. Click the lens to open the Blast Radius panel.

🩻 blast: 12 files
async charge(amount: number): Promise<Receipt> {

See Code Lens for full details.

Hover cards

Hover over any symbol to see its callers inline, with a one-click link to the full Callers panel and Blast Radius panel.

See Hover for full details.

Context Explorer

Travsr: Open Context Explorer (Cmd+Shift+K / Ctrl+Shift+K) opens a panel that runs the full get_context pipeline (PPR, knapsack, KNN, and trust signals) for the symbol under your cursor. It shows one of three states (strong, abstain, or degraded), per-node expandable snippets, a provenance legend, a token-saved bar, and a copy button. See Context Explorer.

Repo Files panel

The Repo Files view in the sidebar is a hierarchical tree of every indexed file, grouped package by package. Click a file to open its file graph. Travsr: Search Files opens a fuzzy QuickPick over all indexed files. See Repo Files Panel.

Editor code actions

Right-click a symbol in the editor, or use the lightbulb, for two context actions:

• Copy Graph Context for Chat (travsr.copyContextForChat): runs get_context for the symbol under the cursor and copies the result to the clipboard so you can paste it into any chat. Respects travsr.contextTokenBudget.
• Check Blast Radius Before Edit (travsr.blastBeforeEdit): runs get_blast_radius for the current file and lists the files that would be affected before you make a change.

Register the MCP server in an agent

Travsr: Register MCP Server in Agent writes the travsr mcp --stdio server entry into an external agent's config file. It supports Claude Desktop, Cursor (workspace .cursor/mcp.json), and Continue, and always shows a diff and asks for confirmation before writing.
