Set up your connector(s)
Paste an API key or sign in with OAuth — HaloPSA, NinjaRMM, CIPP, whatever you run. Credentials go straight to the vault.
Connect your AI
Add our MCP URL — mcp.stackjack.io — to Claude, ChatGPT, or any MCP client. Sign in. Done.
Start asking
Questions that used to mean an afternoon of tab-hopping across three platforms are now one prompt.
Want that to happen every night without asking? Agent Runners run it on a schedule — automation between systems, zero code.
Claude, ChatGPT, Copilot, Cursor + any remote-MCP client. See everything we work with
Plug in once.
Work the whole stack.
StackJack is a remote MCP proxy. Your AI client connects to one endpoint; StackJack brokers every request to the right connector with your credentials and your per-user policy.
Pick a connector, paste credentials
Start free. Paste an API key, Client ID/Secret, or sign in with OAuth PKCE. Credentials sit in a dedicated secrets vault — never in app storage, never logged.
- Encrypted at rest, encrypted in transit
- Rotate or revoke anytime — live
- Works with self-hosted & SaaS deploys
Each teammate signs in as themselves
Invite your team. Every plan — including Free — includes OAuth PKCE and per-user tool restrictions. Sarah gets full access, CI/CD gets create-ticket only, the intern gets search.
Bring your own AI — one endpoint for all of them
Add mcp.stackjack.io to any AI harness that speaks remote (HTTP) MCP. The AI discovers every tool it’s allowed to use — across every connector — and gets back typed, validated responses.
- Any client that supports remote MCP over HTTP/SSE — no SDK lock-in
- Streaming responses, typed errors, retry metadata
- Tool-chain hints so the agent makes fewer mistakes
Every call logged. Nothing retained.
Full audit trail — who called what, when, from where, with what result. But business data passes through, never lands. You see every request; we see none of your clients’ data.
One endpoint. every seat
gets exactly what they need.
Every plan gives your whole team per-user access with custom tool restrictions. The difference between Free, Pro, and Business is scale, not capability.
See the whole business in one query.
Cross-platform visibility without another dashboard. “Which clients are over SLA? Show me backup compliance vs. ticket volume by client.” Claude answers using Halo, Ninja, and CIPP in one pass.
Stop tab-hopping. Start resolving.
Ask “What’s open for Acme?” and Claude pulls tickets from your PSA, recent alerts from your RMM, and the relevant runbook from Hudu. Reply to the ticket straight from the chat.

Explicit tool allow-lists, dry-run mode, max runtime, per-run credit caps — server-enforced.
Visible run history
Status, summary, tokens, tool calls, credits, duration — plus full transcripts on demand.
Credit-based billing
No platform fee. Reserve-then-finalize ledger. Credits never expire. BYOK path for enterprise.
Enterprise-grade security,
MSP-grade simplicity.
StackJack is a proxy — your business data passes through and is never stored, cached, or retained. Credentials live in a dedicated secrets vault.
Common questions.
What’s actually free?
Every connector has a free tier that never expires. In total, 3,847 tools across 34 connectors and the built-in platform tool set are free for life. You can use read-only and basic write tools on any platform without ever paying.
How is my team billed — per user?
No. StackJack bills per connector, not per seat. A Pro subscription to HaloPSA covers your whole team with per-user OAuth PKCE authentication and custom tool restrictions per teammate. Business tier adds 10x volume (50K calls/mo) and Business-tier tools.
Does StackJack store any of my MSP data?
No. We’re a proxy — business data flows through and is never persisted, cached, or indexed. We log metadata (who called what tool, when, duration, result) for your audit trail, but never the payload. Credentials live in a dedicated secrets vault encrypted at rest.
Which AI clients work with StackJack?
Anything that speaks MCP: Claude Desktop, Cursor, Continue, and custom agents using the Anthropic SDK or any MCP-compatible runtime. Add mcp.stackjack.io as a remote server and sign in with OAuth PKCE.
How are Agent Runners billed differently?
Agent Runners are free to create for any StackJack user. You only pay for execution via credit packs — $5 to $200, never expire. Credits reserve before a run and refund the difference after. Enterprise can BYOK their own Anthropic key and skip credits entirely.
What if I need a connector that isn’t listed?
We ship connectors regularly. If you’re an app builder or vendor embedding StackJack, Enterprise plans include custom tool development. Contact us with your stack.
Who lives in the stack.
StackJack is built by Ceej — one of the most experienced HaloPSA implementation specialists on the planet, the MSP Automator behind mspautomator.com, and the creator of BillingBot and QuantumOps. This isn’t built by someone who read the docs last week.
