stelaspace-mcp

stelaspace-mcp


A local MCP server for publishing HTML files to StelaSpace from coding agents that work with your local files — Claude Code and Codex.

It runs on your machine, so it reads HTML files directly from disk by path and uploads the bytes via the StelaSpace API. That's what lets it publish large (1 MB+) reports and dashboards — unlike passing file contents as a tool argument, which is capped by the model's output size.

Claude Desktop (chat) isn't supported for publishing: its sandbox can't share files with a local MCP server, so it can't upload local reports. Use Claude Code or Codex, where the agent generates the report to disk and publishes it directly.

Tools

• publish_file — { path, spaceSlug, title?, slug?, tags?, visibility? } → reads

the file and returns its permanent URL. Reusing a slug publishes a new version.

• list_spaces — list the spaces in your team.
• list_documents — { spaceSlug, query? } — list documents in a space.

Setup

Get an API key from StelaSpace → Settings → API Keys (starts with ss_sk_).

Claude Code

claude mcp add stelaspace --scope user \
  --env STELASPACE_API_KEY=ss_sk_your_key \
  -- npx -y stelaspace-mcp

Codex

~/.codex/config.toml:

[mcp_servers.stelaspace]
command = "npx"
args = ["-y", "stelaspace-mcp"]
env = { STELASPACE_API_KEY = "ss_sk_your_key" }

Then ask the agent to build and publish a report, e.g. "generate the sales dashboard and publish the HTML to my reports space as public."

Environment

• STELASPACE_API_KEY (required) — your ss_sk_ key.
• STELASPACE_API_URL (optional) — override the API endpoint. Defaults to

https://stelaspace.com; most users never need to set this.
