Crate sim_lib_mcp 

Library-only MCP surface projection for SIM.

This crate projects native browse Cards and optional SkillCard records into redacted McpSurfaceCard rows. Routing, transport, and callable execution are implemented by later MCP layers.

Structs

McpAnnotation

Key/value annotation attached to a surface row, with a visibility scope.

McpExportFacet

Describes how a native card subject is exported onto the MCP surface.

McpFunction

Runtime callable object that dispatches one MCP method.

McpLib

Loadable library that registers the MCP method functions in a runtime.

McpNativeCard

Native browse card describing one runtime subject and its MCP facets.

McpProfile

Allow/deny filter that decides which surface rows reach a client.

McpRouter

Dispatches MCP request/notification envelopes against a session.

McpSession

Mutable per-connection MCP session state.

McpSurfaceCard

A single redacted MCP surface row projected from a native or skill card.

Enums

McpAnnotationVisibility

Whether an McpAnnotation is exposed to clients or kept internal.

McpStreamPolicy

Streaming behavior a surface row advertises to clients.

McpSurfaceRole

MCP role that a projected surface row plays for a client.

McpSurfaceSource

Origin record that a projected McpSurfaceCard was derived from.

NativeFacet

A facet attached to an McpNativeCard.

Constants

MCP_LIB_ID

Stable identifier under which this library registers in the runtime.

Functions

Returns the mcp/get-prompt function symbol.

handle_symbol

Returns the mcp/handle function symbol.

health_symbol

Returns the mcp/health function symbol.

initialize_symbol

Returns the mcp/initialize function symbol.

install_mcp_lib

Installs McpLib into cx, loading it once if not already present.

manifest_name

Returns the symbol under which McpLib is registered.

mcp_export_facet_name

Returns the facet name used to mark MCP exports on native cards.

mcp_export_operation_symbol
