pub struct McpServer { /* private fields */ }Expand description
MCP server that exposes Harn tools, resources, and prompts over MCP JSON-RPC.
Implementations§
Source§impl McpServer
impl McpServer
pub fn new( server_name: String, tools: Vec<McpToolDef>, resources: Vec<McpResourceDef>, resource_templates: Vec<McpResourceTemplateDef>, prompts: Vec<McpPromptDef>, ) -> Self
Sourcepub fn with_server_card(self, card: Value) -> Self
pub fn with_server_card(self, card: Value) -> Self
Attach a Server Card to be advertised over initialize and via
the well-known://mcp-card resource. Call on a freshly-built
McpServer before run.
Sourcepub async fn run(&self, vm: &mut Vm) -> Result<(), VmError>
pub async fn run(&self, vm: &mut Vm) -> Result<(), VmError>
Run the MCP server loop, reading JSON-RPC from stdin and writing
to stdout. The transport is split across three concurrent halves:
a stdin reader that demuxes responses to in-flight elicitation
requests away from new client requests, a stdout writer task
that drains the outbound queue, and the main dispatch loop that
owns the VM and processes new requests one at a time. This shape
is what allows a tool handler to call mcp_elicit(...) mid-flight
— the handler awaits an inbound response while the writer keeps
emitting the elicitation request.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
