Travsr for VS Code
Graph-native code intelligence. Live call graph, blast radius, and callers - powered by a local daemon over MCP.
Travsr replaces vector RAG with a deterministic graph. Every function call, import, and type reference becomes a graph edge. Ask "what calls this?", "what breaks if I change this?", or "show me the execution path" - and get exact, always-fresh answers.
Features
- Live call graph - sidebar panel showing the call graph for the active file
- Blast radius - instantly see every file and function that depends on the current symbol
- Callers view - find all call sites for any function across the entire repo
- MCP integration - exposes
get_dependencies, get_callers, get_blast_radius, get_context to Claude and other MCP-capable AI agents
- Always fresh - the graph updates on every git commit via hooks; no stale context
- Zero cloud dependency - the graph daemon runs locally; your code never leaves your machine
Requirements
- VS Code 1.85 or later
- Travsr daemon - the extension auto-installs it on first use
Getting Started
- Install the extension
- Open a git repository in VS Code
- The Travsr daemon starts automatically and indexes your repo
- Open the Travsr panel in the Activity Bar to see your live call graph
- Use
Travsr: Show Callers or Travsr: Show Blast Radius from the command palette
Configuration
| Setting |
Default |
Description |
travsr.binaryPath |
(auto) |
Path to the travsr binary. Leave empty for auto-detect. |
travsr.statusBarPosition |
left |
Which side of the status bar the Travsr indicator appears on. |
travsr.cloudEndpoint |
(empty) |
Remote SSE endpoint URL. Leave empty to use the local daemon. |
travsr.telemetry.enabled |
false |
Send anonymous usage events (opt-in). |
Using with Claude / AI Agents
When the Travsr daemon is running, it exposes an MCP server. Claude Desktop and Claude Code can connect to it automatically. See docs.travsr.com for setup instructions.
Privacy
Telemetry is off by default. When enabled, only anonymous usage events are sent (tool names, connection failures). No file paths, symbol names, or code content is ever sent.
