Action1 MCP Server

MCP server for Action1 — endpoint inventory, patch visibility, and policy automation via the Model Context Protocol.

Read-only in v1. Deploy / automation surface is intentionally separated to a later release for blast-radius reasons (a bad policy push can brick endpoint fleets).

Tools

Tool	Description
action1_navigate	Discover available tools by domain (organizations / endpoints / policies / updates)
action1_list_organizations	List Action1 tenants accessible to the configured credentials
action1_list_endpoints	List managed devices in an organization
action1_get_endpoint	Get a single endpoint by id
action1_list_missing_updates	List missing OS/application patches across endpoints — Action1's headline value-prop
action1_list_policies	List automation / policy / remediation rules

API surface maps to PSAction1 (Action1's MIT-licensed PowerShell module). When the v1 surface earns its keep, write tools (deploy, requery, package upload) come in v2 behind separate review.

Interactive Device Card (MCP Apps)

action1_get_endpoint renders as an interactive device-summary card in MCP Apps hosts (Claude Desktop/web) — status, OS, user, IP, agent version, reboot-required, and missing-update counts at a glance; plain-JSON behavior is unchanged in other hosts. The card is read-only (matching the v1 tool surface), neutral by default, and brandable via window.__BRAND__ injection or MCP_BRAND_* env vars (MCP_BRAND_NAME, MCP_BRAND_LOGO_URL, MCP_BRAND_PRIMARY_COLOR, MCP_BRAND_ACCENT_COLOR, MCP_BRAND_BG, MCP_BRAND_TEXT) — no rebuild needed.

Usage

Claude Desktop (MCPB)

Install via the MCPB bundle from the latest release.

Required credentials (created in Action1 → Settings → API Credentials, non-recoverable on creation — copy immediately):

• API Key (Client ID)
• Secret
• Region (NorthAmerica default; also Europe, AsiaPacific, Australia)
• Optional default organization id (for single-tenant use)

Stdio (direct)

ACTION1_API_KEY=... \
ACTION1_SECRET=... \
ACTION1_REGION=NorthAmerica \
ACTION1_DEFAULT_ORG_ID=org-... \
npx -y github:wyre-technology/action1-mcp

HTTP (gateway mode)

MCP_TRANSPORT=http PORT=8080 AUTH_MODE=gateway \
  docker run -p 8080:8080 ghcr.io/wyre-technology/action1-mcp:latest

Per-request credentials via headers:

• X-Action1-API-Key
• X-Action1-Secret
• X-Action1-Region
• X-Action1-Default-Org-Id

Per-request credential isolation via AsyncLocalStorage — concurrent requests in HTTP mode never share credentials through process.env.
