Model Context Protocol
Bring Constans into the
AI tools you already use.
Constans speaks the Model Context Protocol, the open standard for connecting AI assistants to external systems. Connect it once and your assistant can work with your organisation's governed memory - its scopes, settled decisions, canon and governance alerts - without leaving Claude, ChatGPT or Cursor.
What the skill does
Your assistant, taught to work the way Constans works.
Connecting Constans gives your AI tool the ability to read and record organisational knowledge. The skill teaches it to use that ability well: to search settled canon before answering, to ground new proposals in real events, to respect who can confirm what, and to keep a human in the loop for anything that becomes standing policy.
Setup is two steps: connect the Constans server, then load the guidance.
1. Connect the server
Add the hosted Constans endpoint to your AI tool as a connector and sign in. You authenticate as yourself, so every request stays inside your own memberships and permissions.
2. Load the guidance
Download the skill below and drop it into your tool. It is authored once for Claude and exported for ChatGPT, Cursor and any other assistant, so the behaviour is the same everywhere.
Setup
Connect in a few minutes.
Every AI tool uses the same hosted endpoint. Add it as a connector, then load the matching guidance.
Constans MCP endpoint
https://mcp.constans.appClaude
Connect
In Claude Desktop or claude.ai, open Settings, then Connectors, and add a custom connector using the endpoint above. In Claude Code, run:
claude mcp add --transport http \
constans https://mcp.constans.appLoad the skill
Unzip the download into your skills folder, or upload the zip under Settings, then Capabilities, then Skills on claude.ai. Claude loads it automatically when it is relevant.
ChatGPT
Connect
Enable connectors, add the endpoint above as an MCP connector, and sign in. Availability of custom connectors depends on your ChatGPT plan.
Load the skill
Create a Custom GPT and paste the included system prompt into its instructions. The reference files can be uploaded as knowledge for deeper lookups.
Cursor
Connect
Add the server to your Cursor MCP config, then complete sign-in on first use:
{
"mcpServers": {
"constans": {
"url": "https://mcp.constans.app"
}
}
}Load the skill
Copy the included Cursor rule into your project's rules folder.
Using a different assistant? Any MCP client can connect to the same endpoint. Paste the host-neutral system prompt from the download as your custom instructions. Full per-tool steps are included in the package README.
The package
One download, every assistant.
The zip contains the Claude skill plus host-neutral exports and a setup README. It carries no credentials - you sign in to Constans through your own connector.
The skill
A Claude skill and a full reference: how each capability works, the domain model, and worked examples for common tasks.
Portable exports
A host-neutral system prompt for ChatGPT and other assistants, plus a ready-made Cursor rule.
Setup README
Step-by-step connection instructions for Claude, ChatGPT, Cursor and any generic MCP client.
