How to Use the Fastn MCP in VS Code Copilot

Q: How do we set up the Fastn MCP Server for our entire team in VS Code Copilot?

Create a .vscode/mcp.json file in your repository's root directory and commit it. Every team member using VS Code Copilot with Agent mode enabled will automatically inherit the MCP configuration.

Q: How does VS Code Copilot monitor our Fastn quota usage?

Copilot can call getquotadaily and getquotasummary to fetch real-time usage metrics. This helps your team monitor consumption trends directly from the chat panel.

Perplexity

Share Fastn workflow configurations across your team

Keeping your team's local environments in sync with your production workflows is easy when VS Code Copilot uses `list_workflows` to fetch active definitions. This shared setup means any developer can inspect active flow definitions without needing administrative access to a separate web console. You can quickly verify how triggers are structured, making collaboration on complex integrations completely straightforward. The agent calls `get_workflow` to verify schemas, keeping your team aligned on payload structures.

Track production executions using this MCP Server

Debugging enterprise automation pipelines requires clear visibility, which VS Code Copilot gets by calling `list_executions` to query your tenant's history. This allows your developers to spot patterns in failing integration steps without digging through external logs. If a specific run requires closer inspection, the agent invokes `get_execution` to pull the complete trace. Having this capability inside your primary editor speeds up incident response times for your entire engineering team.

Manage flow lifecycles and credentials securely

Deploying updates to your automation flows is simple when your editor handles the lifecycle via `update_workflow`. The agent pushes those changes live with `publish_workflow` to create a smooth path from local editing to production. Managing credentials across different environments is equally secure. Your team can use `store_credentials` and `rotate_credentials` to update API keys safely, ensuring that your automated steps always have the correct permissions to run.

Setup guide

Set up Fastn MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the Fastn MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the Fastn tools listed. Try asking: "List my recent Fastn transactions" and Copilot will invoke them automatically.

.vscode/mcp.json

{
  "mcpServers": {
    "fastn-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
