InsightSentry

MCP server and CLI for the InsightSentry financial data API.

Install

npm install -g @insightsentry/mcp

Commands:

Command	Purpose
insight	CLI for terminal use and scripts
insight-mcp	MCP server for AI clients
mcp	Alias for insight-mcp

Authentication

Set an API key for the current shell:

export INSIGHTSENTRY_API_KEY="your-api-key"

Or save one locally for the CLI:

insight login --key "your-api-key"
insight whoami
insight logout

whoami parses the configured JWT locally and prints uuid, falling back to email then sub.

MCP Setup

Use npx in your MCP config:

{
  "mcpServers": {
    "insightsentry": {
      "command": "npx",
      "args": ["-y", "@insightsentry/mcp"],
      "env": {
        "INSIGHTSENTRY_API_KEY": "your-api-key"
      }
    }
  }
}

The MCP server also falls back to the key saved by insight login when INSIGHTSENTRY_API_KEY is not set. Set INSIGHTSENTRY_CONFIG_DIR to force the CLI and MCP server to read the same saved-login directory when they run with different home directories.
