README

From the repo.

opensrc

Give coding agents access to any package's source code.

Quick Start

npm install -g opensrc

# Search a package's source
rg "parse" $(opensrc path zod)

# Read a specific file
cat $(opensrc path zod)/src/types.ts

# Works with any registry
find $(opensrc path pypi:requests) -name "*.py"

opensrc path fetches on first use, then returns the cached path instantly. See the CLI readme for full usage.

Config for your environment

Replace {MCP_ENDPOINT_URL} with this MCP’s endpoint URL (from its repo or docs above). No API key — you connect directly.

Tool

OS

Config file: ~/.cursor/mcp.json

{
  "mcpServers": {
    "mcp-server": {
      "url": "{MCP_ENDPOINT_URL}"
    }
  }
}

Paste into mcpServers in the config file. Restart Cursor after saving.

If this MCP is also published on mcpchannel.ai, you can subscribe from Browse and use the gateway config there instead.
