OPCFoundation.NetStandard.Opc.Ua.Mcp.Vision

OPC UA Model Context Protocol (MCP) tools that let a language model see through an OPC UA Vision server and act on what it sees, packaged so they can be embedded in any MCP server host rather than only run as the shipped opcua-mcp tool.

Use this package when an application wants an LLM agent to enumerate Vision sensors and pipelines, capture the current camera frame as MCP image content, run inference or submit off-server perception feedback, and compose poses between named coordinate frames.

The headline capability

vision_get_frame returns the encoded still image as an MCP ImageContentBlock with the correct MIME type, so the model actually sees pixels rather than reading a description of them. When the server cannot render — for example on CI without a graphics device — the tool returns an actionable text explanation instead of a broken image.

vision_run_inference accepts one structured request and returns the ResultId, result NodeId, authoritative result kind and provenance in the same call. Its default Summary detail includes a bounded detection, inspection or segmentation summary; use the corresponding vision_read_*_result tool for the complete result. Pipelines can be selected by NodeId or by an exact, unambiguous BrowseName/DisplayName:

{
  "request": {
    "pipeline": "BinPickingPipeline",
    "expectedKind": "Detection",
    "detail": "Summary",
    "maxItems": 20
  }
}

Tools (22)

  • Discovery (4) — vision_list_sensors, vision_list_pipelines, vision_list_frames, vision_list_calibrations.
  • Monitoring (6) — vision_read_sensor, vision_read_extrinsic_calibration, vision_read_pipeline, vision_read_detection_result, vision_read_inspection_result, vision_read_segmentation_result.
  • Seeing (2) — vision_get_frame (ImageContentBlock), vision_get_frame_metadata.
  • Inference (3) — vision_run_inference, vision_start_continuous_inference, vision_stop_inference.
  • Feedback (4) — vision_submit_detections, vision_submit_inspection_result, vision_submit_correction, vision_submit_image_reference.
  • Geometry (3) — vision_read_frame, vision_compose_pose, vision_compose_transform.

Server refusals are returned honestly with the exact StatusCode and message; the MCP layer does not retry and never acquires command authority as a side effect.

Usage

Standalone vision profile

Every Vision tool resolves a named OPC UA session, and only the connection tools can open one. The single-profile overload therefore carries ConnectionTools itself, so the bounded vision profile is usable end-to-end without composing with any other package:

using Microsoft.Extensions.DependencyInjection;
using Opc.Ua.Mcp;

builder.Services.AddOpcUaMcpCore();
builder.Services.AddOpcUaMcpVision();

builder.Services.AddMcpServer()
    .WithStdioServerTransport()
    .WithOpcUaMcpFilters()
    .WithOpcUaCoreTools(McpToolProfile.Vision)
    .WithOpcUaVisionTools(McpToolProfile.Vision);

Composed with robotics

Use the McpToolProfileSet overloads to combine Vision with Robotics — the composition the BinPickingClient sample runs. The core-tools overload owns and deduplicates ConnectionTools across every package that references the same MCP server:

using Opc.Ua.Mcp;

McpToolProfileSet profiles = new McpToolProfileSet(
    new[] { McpToolProfile.Vision, McpToolProfile.Robotics });

builder.Services.AddOpcUaMcpCore();
builder.Services.AddOpcUaMcpVision();
builder.Services.AddOpcUaMcpRobotics();

builder.Services.AddMcpServer()
    .WithStdioServerTransport()
    .WithOpcUaMcpFilters()
    .WithOpcUaCoreTools(profiles)
    .WithOpcUaVisionTools(profiles)
    .WithOpcUaRoboticsTools(profiles);

A profile that does not select Vision contributes no tools rather than failing, so the same profile value can be passed to every OPC UA tool package a host references.

Package Adds
OPCFoundation.NetStandard.Opc.Ua.Mcp.Core Part 4 service tools, session management, filters (required)
OPCFoundation.NetStandard.Opc.Ua.Vision.Client Vision discovery, sensors, frames, media, inference, feedback client API
OPCFoundation.NetStandard.Opc.Ua.Mcp.Robotics Robot Intent tools that pair with Vision for pick-and-pack scenarios
OPCFoundation.NetStandard.Opc.Ua.Mcp the ready-to-run opcua-mcp server composing all OPC UA MCP tool packages

See the Vision developer guide and the MCP Server guide for the profile table, composition rules and the bin-picking sample.
