HaloPSA MCP Server

A Model Context Protocol (MCP) server for interacting with HaloPSA, featuring a decision tree architecture for efficient tool loading.

One-Click Deployment

Architecture

This MCP server uses a hierarchical tool loading approach instead of exposing all tools upfront:

1. Navigation Phase: Initially exposes only a navigation tool (halopsa_navigate)

2. Domain Selection: User selects a domain (tickets, clients, assets, agents, invoices)

3. Domain Tools: Server exposes domain-specific tools after selection

4. Lazy Loading: Domain handlers and the HaloPSA client are loaded on-demand

This architecture provides:

• Reduced cognitive load (fewer tools to choose from)

• Faster initial load times

• Better organization of related operations

• Clear navigation state

Installation

This package is published to the GitHub Packages npm registry, which requires a token even for public packages. Authenticate once, then install:

# Authenticate npm to GitHub Packages (token needs the read:packages scope)
export NODE_AUTH_TOKEN=$(gh auth token)   # or a PAT with read:packages

npm install @wyre-technology/halopsa-mcp

The repo's .npmrc already points the @wyre-technology scope at GitHub Packages and reads the token from NODE_AUTH_TOKEN, so no further config is needed.

Configuration

Set the following environment variables:

Usage

Running Standalone

# Set credentials
export HALOPSA_CLIENT_ID="your-client-id"
export HALOPSA_CLIENT_SECRET="your-client-secret"
export HALOPSA_TENANT="yourcompany"

# Run the server
npx @wyre-technology/halopsa-mcp

User: Check my tickets
Claude: [calls halopsa_navigate with domain="tickets"]
       -> Navigated to tickets domain. Available tools: ...

User: List open tickets
Claude: [calls halopsa_tickets_list with open_only=true]
       -> [ticket list results]

User: Now show me clients
Claude: [calls halopsa_back]
       -> Navigated back to main menu.
       [calls halopsa_navigate with domain="clients"]
       -> Navigated to clients domain.

Rate Limiting

HaloPSA has a rate limit of 500 requests per 3-minute window. The underlying @asachs01/node-halopsa client handles this automatically with request throttling.
