MCP server that lets AI agents search the substreams.dev package registry.

Tool: `search_substreams`

Parameter	Type	Default	Description
`query`	string (required)	—	Search term, e.g. `"solana dex"` or `"uniswap"`
`sort`	string	`"most_downloaded"`	`most_downloaded`, `alphabetical`, `most_used`, `last_uploaded`
`network`	string	—	Filter by chain: `ethereum`, `solana`, `arbitrum-one`, etc.

Returns JSON with package name, URL, creator, network, version, published date, and download count.

Quick Start (npx)

No installation needed:

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "substreams-search": {
      "command": "npx",
      "args": ["substreams-search-mcp"]
    }
  }
}

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "substreams-search": {
      "command": "npx",
      "args": ["substreams-search-mcp"]
    }
  }
}

Claude Code

Add to ~/.claude/mcp.json:

{
  "mcpServers": {
    "substreams-search": {
      "command": "npx",
      "args": ["substreams-search-mcp"]
    }
  }
}

How it works

The substreams.dev registry has no public API. This server scrapes the package listing pages, paginates through all results, deduplicates, and returns structured JSON. Multi-word queries search for the first word server-side and filter the rest client-side.
