Enum McpErrorKind 

pub enum McpErrorKind {
    InvalidParams,
    Retryable {
        code: i32,
        data: Value,
    },
    Internal,
}

JSON-RPC error-code classification for an Error, returned by Error::mcp_error_kind.

mcpls-core has no dependency on the MCP transport crate, so this carries only plain data; crate::mcp is responsible for turning it into the actual wire-level error type.

Examples

use mcpls_core::error::{Error, McpErrorKind};

let err = Error::InvalidToolParams("missing `file_path`".to_string());
assert_eq!(err.mcp_error_kind(), McpErrorKind::InvalidParams);

Variants

InvalidParams

Caller-fault: the request itself was invalid. Maps to JSON-RPC -32602 (INVALID_PARAMS).

Retryable

A transient, retryable server-side condition, distinct from a crash. Maps to a bespoke JSON-RPC code with a structured data payload a caller can act on mechanically, rather than the generic INTERNAL_ERROR.

Fields

code: i32

Bespoke JSON-RPC error code.

data: Value

Structured details about the retryable condition.

Internal

An unexpected server-side failure. Maps to JSON-RPC -32603 (INTERNAL_ERROR).
