ContentItem

using @colmugx/mcp/protocol/types { type ContentItem }

Content item for MCP tool results

JsonRpcRequest

using @colmugx/mcp/protocol/types { type JsonRpcRequest }

JsonSchema

using @colmugx/mcp/protocol/core { type JsonSchema }

MCPError

using @colmugx/mcp/protocol/types { type MCPError }

MCP protocol-level errors These follow the JSON-RPC 2.0 error code conventions.

Error code allocation (per 2026-07-28 spec):

-32700, -32600..-32603: standard JSON-RPC 2.0
-32000..-32019: legacy/implementation-defined (no new allocations)
-32020..-32099: reserved for the MCP specification

ParamDef

using @colmugx/mcp/protocol/tool { type ParamDef }

Parameter definition for tool schema

Params

using @colmugx/mcp/protocol/core { trait Params }

ServerCapabilities

using @colmugx/mcp/protocol/types { type ServerCapabilities }

ServerInfo

using @colmugx/mcp/protocol/types { type ServerInfo }

Tool

using @colmugx/mcp/protocol/tool { trait Tool }

ToolDefinition

using @colmugx/mcp/protocol/types { type ToolDefinition }

ToolError

using @colmugx/mcp/protocol/core { type ToolError }

ToolResult

using @colmugx/mcp/protocol/tool { type ToolResult }

Tool execution result following MCP protocol format

TransportError

using @colmugx/mcp/protocol/types { type TransportError }

Transport-level errors These occur at the communication layer (network, IO, etc.)

ToolResult) -> @colmugx/mcp/protocol/core.ToolWrapper
ToolWrapper

tool_fn

fn[Args : @colmugx/mcp/protocol/core.Params
Params, Ret : @colmugx/mcp/protocol/core.ToToolResult
