Use Comma with LM Studio

Running the model locally keeps the reasoning on your machine; the report it writes still has to reach people. LM Studio supports remote MCP servers, so a local model with tool use can publish its output to Comma and hand back a link — the report is the only thing that leaves.

Add Comma to LM Studio

In LM Studio, open the Program tab in the right sidebar → InstallEdit mcp.json.

{
  "mcpServers": {
    "comma": {
      "url": "https://commareports.com/api/mcp",
      "headers": {
        "Authorization": "Bearer comma_sk_…"
      }
    }
  }
}

Replace comma_sk_… with a token from Settings → API tokens → New token on Comma (or export it as COMMA_API_TOKEN where the snippet reads an env var). The default scopes — reports:write, comments:read, comments:write — cover publishing and review.

LM Studio gotchas

  • Pick a model that does tool calling well. Small models call create_report with truncated HTML; give the model the full document in one message and ask it to publish that.
  • Keep tool-call confirmation on for update_report and set_report_sharing — those change what reviewers see.
  • Scope the token to reports:write only if the model never needs to read comments.

What the agent can do

Capability Tools
Publish a report create_report, update_report, create_report_from_url
Find existing reports list_reports, search_reports, get_report, read_report
Leave / reply to comments add_comment, reply_to_comment, set_comment_status, list_comments
Ask for review, share request_review, set_report_sharing, get_report_signoffs
Manage assets upload_report_asset, list_report_assets, delete_report_asset

Your local model picks the tool from the request — there are no LM Studio-specific commands to learn.

A workflow that sticks

  1. Ask your local model to write up the work as a self-contained HTML report and publish it to Comma. It calls create_report and returns a link.
  2. Send the link. Reviewers open a rendered page and leave comments anchored to the exact line, cell or chart they mean — no account needed to read a public link.
  3. Next session, ask your local model to address the comments. It reads the threads with list_comments, ships a revision with update_report (same URL), replies, and resolves them.

Reports belong to your workspace, not to the agent. A report published from LM Studio can be revised tomorrow from Claude Code or Cursor, and the link people bookmarked keeps working.

Token shape

  • Lives in LM Studio's mcp.json on your machine.
  • Scoped — you choose which actions it can take when you create it.
  • Revocable in one click from Settings → API tokens; revocation applies immediately to the REST API, the MCP server and any routines the token created.
  • Rate-limited per token.

Try it

Add the entry, generate a token, restart LM Studio, and ask for a report on something you worked on today. Then leave a comment on it and ask the agent what it sees.
