Class BowireMcpProtocol

Namespace

Kuestenlogik.Bowire.Protocol.Mcp

Assembly

Kuestenlogik.Bowire.Protocol.Mcp.dll

Bowire protocol plugin for the Model Context Protocol (MCP). Connects to a remote MCP server, discovers its tools / resources / prompts, and lets the user invoke them — analogous to the gRPC and REST plugins.

Remarks

Built on the official ModelContextProtocol C# SDK (ModelContextProtocol.Client.McpClient + ModelContextProtocol.Client.HttpClientTransport) — the previous hand-rolled JSON-RPC client predates the SDK's client surface. The SDK handles spec-version negotiation, Streamable-HTTP- vs-SSE auto-detection, session resumption, and the JSON-RPC wire envelope.

The companion MapBowireMcpAdapter(IEndpointRouteBuilder, string) extension lives in the same assembly but is unrelated to discovery: it is an opt-in development feature that goes the other direction (Bowire's services exposed as MCP tools so AI agents can call them). The adapter is hand-rolled because it sits on Bowire's own BowireProtocolRegistry rather than ASP.NET MCP middleware.

Properties

Description

One-line description shown next to the plugin's display name in Settings → Plugins. Optional; defaults to empty so the row falls back to "DisplayName + version" without the description line. Keep it short (≤ 100 characters) — the row truncates anything wider than the manage panel.

public string Description { get; }

Property Value

string

IconSvg

SVG icon for the protocol tab.

public string IconSvg { get; }

Property Value

string

Id

Short identifier (e.g., "grpc", "signalr").

public string Id { get; }

Property Value

string

Name

Protocol name shown in UI tabs.

public string Name { get; }

Property Value

string
