### Description (declared)

# ParaView MCP Server

Control ParaView with AI assistants through the Model Context Protocol (MCP).

`paraview-mcp-python` provides an MCP server and a ParaView-side bridge. MCP clients such as Codex CLI and Claude Desktop can use it to inspect a ParaView session, open datasets, apply filters, color data, run ParaView Python, and export screenshots.

The MCP server command is:

```bash
paraview-mcp-server
```

## Architecture

The GUI workflow has four components:

| Component | Runs in | Purpose |
|---|---|---|
| MCP client | Codex CLI, Claude Desktop, or another MCP host | Starts the MCP server and calls its tools. |
| MCP server | Standard Python environment | Communicates over MCP stdio and forwards calls to ParaView over TCP. |
| ParaView bridge | `pvpython` process | Receives JSON commands over TCP and executes `paraview.simple` operations. |
| ParaView runtime | `pvserver` and a ParaView GUI client | Owns the shared session used by the GUI and bridge. |

ParaView Python plugins and VTK timer callbacks are pipeline-extension mechanisms, not a general-purpose remote-control interface for a live GUI process. This project therefore uses ParaView's client/server model.

`paraview-mcp-launch` starts a local `pvserver`, connects the ParaView GUI as the first client, and then connects a `pvpython` bridge to the same session.
