Scorecard AI helps developers evaluate and improve AI agents and LLM applications by creating test datasets, defining evaluation metrics, running automated evaluations, analyzing scores, managing system versions, and reviewing annotations.
Claude is Anthropic's AI assistant, available as a desktop app and in Cowork. It supports custom connectors, so it can call MCP servers directly from a chat.
This guide connects Scorecard MCP to Claude Desktop through MewCP, so Claude Desktop can use Scorecard MCP's 2 tools, like execute and search_docs, without your Scorecard MCP credentials ever reaching the app.
Scorecard MCP signs in through managed OAuth. MewCP stores the token encrypted, refreshes it before it expires and injects it only at call time. Your agent never holds it, so it can never leak it.

Other clients
Scorecard MCP works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Scorecard MCP tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
In Claude, open Settings → Connectors, then choose Add custom connector.
Name it "mewcp" and paste the URL.
A browser window opens the first time the client connects. Sign in and approve access. No API key needed.
Start a new chat and ask: "List the tools you can use from MewCP." You should see your connected apps.
Runs JavaScript code to interact with the Scorecard API. You are a skilled TypeScript programmer writing code to interface with the service. Define an async function named "run" that takes a single parameter of an initialized SDK client and it will be run. For example: ``` async function run(client) { const run = await client.runs.create('314', { metricIds: ['789', '101'], testsetId: '246' }); console.log(run.id); } ``` You will be returned anything that your function returns, plus the results of any console.log statements. Do not add try-catch blocks for single API calls. The tool will handle errors for you. Do not add comments unless necessary for generating better code. Code will run in a container, and cannot interact with the network outside of the given SDK client. Variables will not persist between calls, so make sure to return or log any data you might need later. Remember that you are writing TypeScript code, so you need to be careful with your types. Always type dynamic key-value stores explicitly as Record<string, YourValueType> instead of {}.
Search SDK documentation to find methods, parameters, and usage examples for interacting with the API. Use this before writing code when you need to discover the right approach.
