Blocksize Cursor Plugins

This repository contains Cursor plugin packaging for Blocksize's hosted MCP market-data services. It is the marketplace source repo for Cursor-specific integrations that connect agents to mcp.blocksize.info.

The first plugin in this repo is blocksize-market-data, a Clerk-authenticated remote MCP connection for read-only live crypto, equity, FX, and metals data in Cursor.

What This Repo Publishes

• Cursor marketplace metadata in .cursor-plugin/marketplace.json.
• The installable blocksize-market-data plugin package.
• The MCP configuration that points Cursor at https://mcp.blocksize.info/cursor/mcp/.
• User-facing documentation for supported tools, data offerings, auth, and testing.

Plugin

blocksize-market-data gives Cursor agents access to Blocksize's hosted MCP server at mcp.blocksize.info. The Cursor integration is intentionally separate from Blocksize's public paid API and registry flows:

• Cursor uses Clerk OAuth sign-in and server-side daily credits.
• Public registry and payment integrations are handled outside this Cursor plugin.
• The plugin is read-only and cannot execute trades, wallet transfers, or other account-changing actions.

See plugins/blocksize-market-data/README.md for the full plugin documentation.

Blocksize MCP Server

Main server:

https://mcp.blocksize.info

Cursor MCP endpoint:

https://mcp.blocksize.info/cursor/mcp/

Public MCP endpoint:

https://mcp.blocksize.info/mcp/server/

The hosted server exposes discovery and market-data tools for crypto, equities, FX, and metals. Cursor users authenticate through Clerk, then consume daily server-side credits for live read-only data calls.
