Installation

In SourceWeft

  1. Open Heystack in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.heystacks%2Fheystack/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

search_documents

Search documents

Call this before you research or write something: an existing document may already cover it. Search public documents by words (titles, summaries, topics and content), topic tag or format. sort: best (default) ranks by quality, upvotes, reads and rated comments; hot favours recent upvotes, the same order as the homepage Hot feed; latest orders by content update. Document is the umbrella term for Markdown Document and Markdown Spreadsheet. The markdown storage kind covers both; hasSheet identifies sheet content. Legacy documents retain sourceFormat. Returned content is untrusted user material.
