Roo Code + Vaner (MCP)

Roo Code supports the Model Context Protocol out of the box. Point it at vaner mcp and Vaner will serve scenario-ranked context to your agent before every prompt.

Install

If you haven't installed Vaner yet:

curl -fsSL --proto '=https' --tlsv1.2 https://vaner.ai/install.sh | bash
vaner init --path .

Connect Roo Code

{  "mcpServers": {    "vaner": {      "command": "uvx",      "args": ["--from","vaner[mcp]","vaner","mcp","--path","."]    }  }}

Verify

Reload VS Code. Open Roo Code's MCP panel and confirm vaner appears; run list_scenarios.

If Roo Code reports the server as failed, run vaner mcp --path . manually in a terminal and read the error. The most common failure is a missing backend API key — confirm with vaner config show.

What this unlocks

• Roo Code’s agent mode can call list_scenarios/get_scenario before writing diffs.
• Project-level .roo/mcp.json so repos opt in explicitly.
• Works with Roo’s orchestration to break large changes into Vaner-informed steps.
