For developers and AI agents

Connect AI assistants to Calibrum's Delphi knowledge.

A free, read-only MCP server and REST API give AI agents the same Delphi guides and Surveylet Help Center answers that are published on this site. No account or API key is needed.

MCP server

The Model Context Protocol lets AI assistants such as Claude, ChatGPT, Cursor and VS Code use external tools. Add Calibrum's server to let an assistant search the Surveylet Help Center and read Calibrum's guides while it answers your questions.

Add it to an AI assistant

In assistants that support custom connectors, add a remote MCP server with this URL:

https://calibrum.com/mcp

For clients configured with a JSON file:

{
  "mcpServers": {
    "calibrum": {
      "type": "http",
      "url": "https://calibrum.com/mcp"
    }
  }
}

For Claude Code:

claude mcp add --transport http calibrum https://calibrum.com/mcp

What the server and API do not do

They cannot sign in to Surveylet or read any account, study, participant or response data.
They cannot create, change or delete anything.
They return only content that is already public on calibrum.com.

If you would like an integration that works with your own Surveylet studies, contact us.
