}

Configuration for native (in-process) tool implementations.

Native tools bypass MCP serialization for maximum performance. Each category can be independently enabled/disabled and security-scoped.

Fields

file_tools_enabled: bool

Enable file_read / file_write / file_patch (default: false — opt-in).

file_allowed_paths: Vec<String>

Directory prefix allowlist for file tools. Empty = deny all. Use ["*"] to allow all paths (not recommended in production).

file_max_size_kb: u64

Maximum file size in KB that file_read may return (default: 1024).

file_write_max_kb: u64

Maximum file size in KB that file_write may create/overwrite (default: 512).

web_fetch_enabled: bool

Enable the web_fetch native tool (default: false).

web_fetch_timeout_secs: u64

Request timeout for web_fetch in seconds (default: 30).

web_fetch_max_size_kb: u64

Maximum response body size in KB (default: 512).

web_fetch_allowed_domains: Vec<String>

Domain allowlist for web_fetch. Empty = allow all domains.

terminal_exec_enabled: bool

Enable terminal_exec (default: false; routes through sandbox when enabled).

terminal_shell: String

Shell binary for terminal_exec (default: “sh”).

terminal_timeout_secs: u64

Per-command timeout in seconds for terminal_exec (default: 30).

terminal_use_sandbox: bool

Route through the configured sandbox runner (default: true).

session_search_enabled: bool

Enable session_search (default: true when persistence is configured).

session_search_max_results: usize

Maximum results returned by session_search (default: 10).

Trait Implementations

impl Clone for NativeToolsConfig

fn clone(&self) -> NativeToolsConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NativeToolsConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NativeToolsConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NativeToolsConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for NativeToolsConfig

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for NativeToolsConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
