What your AI can do with Promise
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “connect_promise”: Return a Promise signup URL for users who want agent access to follow-up memory. Safety: Never collects provider credentials in the agent. S.”
“Use “get_today”: Return what currently deserves the user's attention. Safety: Return concise items and links back to Promise for sensitive action.”
“Use “list_commitments”: List what the user owes and what the user is waiting on. Safety: Do not infer more certainty than Promise returns.”
“Use “get_commitment”: Retrieve a structured Promise commitment or waiting-on item. Safety: Prefer structured status, due dates, people, and source links over raw.”
How secure is the Promise MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Promise holds up.
Official endpoint
Operated by Promise (usepromise.ai) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Promise adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Who runs the Promise MCP server?
The Promise MCP server at a glance
https://mcp.usepromise.ai/mcpQuestions, answered
Is there an official Promise MCP server?
Yes — Promise operates its own remote MCP server at mcp.usepromise.ai. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Promise to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Promise in the directory. No account or sign-in is needed. From then on, Promise's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Promise runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Promise MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Promise in minutes. No credit card required.
