Overview

AI-generated overview

Slabline is a remote MCP server that lets an assistant search a catalogue of graded trading cards and look up their current values by grade.

What you can do
Search graded sports and TCG cards by player, set or year, returning up to 10 matches ordered by value with an id for each card. Fetch a single card by id to get its graded market value, raw/loose value and across-grades total. Look up a card's value from a slug or a free-text query, using the top match.
When to use it
Useful when you want an assistant to find a specific graded card and report what it is currently worth, or to compare values across several cards or grades without leaving the conversation.
Requirements
A remote streamable HTTP endpoint at slabline.ai; no packages, environment variables or headers are declared. No authentication is declared, so no account or API key is needed.
Before you install
Values are Slabline-derived estimates updated daily, not individual sale records, so treat them as indicative rather than authoritative pricing. The server is read-only and does not expose comparable-sale rows.

Installation

In SourceWeft

  1. Open Slabline 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/ai.slabline%2Fslabline/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
