OpenFile

MCP tool from Pulsar MCP by asiloisad-pulsar

Open an existing file in editor with optional position (create=true allows new files)

How to use it

Project documentation lists OpenFile for the Pulsar MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
