MCP Server

Connect AI assistants to the Contact API. Works with Cursor, VS Code, Claude Desktop, and any MCP-compatible client.

Endpoint: https://app.tendrl.com/contact/mcp

Copy this config into your MCP client:

json


{
  "mcpServers": {
    "contact": {
      "type": "http",
      "url": "https://app.tendrl.com/contact/mcp",
      "headers": {
        "Authorization": "Bearer <CONTACT_API_KEY>"
      }
    }
  }
}

Create API keys in the Contact dashboard under Access Control → API Keys. The MCP tools call IAM- and account-gated endpoints, so connect with an account API key whose role grants those actions (the built-in Admin role is the simplest choice). An entity-bound key with the DefaultEntity role will connect but 403 on most tools.

Claude Code Skills

When you add the Contact MCP server to Claude Code, skills are served automatically, no plugins needed. Just add the MCP config above and Claude discovers contact-devices and contact-admin skills via the server's resources endpoint.

Local Dev Server

Flash firmware, upload code, and debug MicroPython devices from an AI assistant over USB serial.

Install with one command — it detects your platform, verifies checksums, and puts tendrl-dev-mcp on your PATH (which is exactly the bare command the MCP config above launches):

bash


# macOS / Linux
curl -fsSL https://app.tendrl.com/api/public/tools/dev-mcp/v1/latest/install.sh | sh

powershell


# Windows
powershell -c "irm https://app.tendrl.com/api/public/tools/dev-mcp/v1/latest/install.ps1 | iex"

The installer downloads with curl, so macOS Gatekeeper and Windows SmartScreen never flag the binary. Prefer a raw artifact? Direct downloads:

Platform	Download
macOS (Apple Silicon)	tendrl-dev-mcp-darwin-arm64
macOS (Intel)	tendrl-dev-mcp-darwin-amd64
Linux (x86_64)	tendrl-dev-mcp-linux-amd64
Linux (ARM64)	tendrl-dev-mcp-linux-arm64
Windows	tendrl-dev-mcp-windows-amd64.exe

Verify a direct download against SHA256SUMS.txt, then chmod +x it and rename it onto your PATH (browser downloads of unsigned binaries also get flagged by Gatekeeper/SmartScreen — the install command avoids that). To pin a specific build, swap latest for a version tag; the current release and its checksums are listed at /api/public/tools/dev-mcp/v1/meta.

Claude Code skills: When added to your MCP config, the dev server automatically serves dev-provision, dev-files, dev-debug, and tendrl-orchestrate skills.
