Getting Started
Set Up Environment Variables
Create a .env file at the root of your project:
touch .env
Add the following to .env:
LANGSMITH_API_KEY=lsv2_... OPENAI_API_KEY=sk-...
Next, navigate to the agent folder and create another .env file:
cd agent touch .env
Add the following inside agent/.env:
OPENAI_API_KEY=sk-... LANGSMITH_API_KEY=lsv2_...
Set Up Poetry:
Poetry manages dependencies for the agent service. Install it with:
pip install poetry
Verify the installation by running:
poetry --version
Development
For easier debugging, run the frontend and agent in separate terminals:
# Terminal 1 - Frontend pnpm run dev-frontend # Terminal 2 - Agent pnpm run dev-agent
Alternatively, launch both services together:
pnpm run dev
Visit http://localhost:3000 in your browser to view the application.
Architecture
The codebase is organized into two primary components:
- Frontend - Handles the user interface.
- Agent - Manages the core functionality.

Questions
What is the Open Mcp Client MCP server?
None
What tools does Open Mcp Client expose?
5 in total: 4 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Open Mcp Client safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Open Mcp Client need?
It reads LANGSMITH_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does Open Mcp Client run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as whiteboard-canvas at 0.1.0.
How current is this page?
The grade is for one exact copy of the source (918b6788787b), read on 2026-09-24. The repository is watched and re-audited when it changes.
