Overview

AI-generated overview

Remote MCP server that lists published Clearbar verdicts on the cheapest LLM that still passes a quality bar for a given task, with cost per successful task.

What you can do
  • List published verdicts, optionally filtered by task type, showing the task, pass bar, cheapest passing model, cost per successful task and the page to check it
  • Fetch the full verdict for one task by slug: pass rate, cost per successful task in US dollars, the baseline model, every candidate's status, and links to the verdict page, run file and re-run script
  • Report measured figures from public datasets with retries and failures counted, including a dated price snapshot
When to use it
Useful when choosing which model to run for a specific task and wanting a cost-versus-quality comparison rather than raw benchmark scores, or when checking whether a cheaper model clears an existing quality bar.
Requirements
A remote streamable HTTP endpoint; no packages, environment variables or headers are declared, and no authentication is declared.
Before you install
Verdicts are published measurements on public datasets with a dated price snapshot, so costs may not match current pricing or your own data; the server only reads published verdicts and does not run evaluations on your examples.

Installation

In SourceWeft

  1. Open Clearbar model verdicts 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.grain64.clearbar%2Fverdicts/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

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
