Struct McpMonitor 

pub struct McpMonitor { /* private fields */ }

MCP Protocol Security Monitor.

Tracks registered MCP servers and their tools, validates server trust, detects injection in tool schemas and responses, and flags exfiltration attempts.

Implementations

impl McpMonitor

pub fn new(config: McpMonitorConfig) -> Self

Create a new monitor from the given configuration.

pub fn with_defaults() -> Self

Create a monitor with sensible defaults.

pub fn register_server( &mut self, uri: &str, name: &str, tools: HashMap<String, String>, ) -> Result<(), Vec<McpSecurityViolation>>

Register an MCP server and its tools.

Returns an error if the server is not on the allowlist, or if any tool triggers a security violation (shadowing, schema injection, etc.).

pub fn validate_server(&self, uri: &str) -> ServerValidation

Validate whether a server URI is on the allowlist.

pub fn validate_tool_schema( &self, _tool_name: &str, description: &str, param_descriptions: &[&str], ) -> SchemaValidation

Scan a tool’s description and parameter descriptions for injection patterns.

pub fn detect_tool_shadowing( &self, tool_name: &str, server_uri: &str, ) -> Option<ShadowingAlert>

Detect if a tool name is already registered by a different server.

pub fn validate_tool_response( &self, _tool_name: &str, response_content: &str, ) -> ResponseValidation

Validate a tool’s response content for injection and exfiltration.

pub fn scan_for_injection(&self, text: &str) -> Vec<InjectionIndicator>

Scan arbitrary text for instruction-like injection patterns.

pub fn check_exfiltration_indicators( &self, content: &str, ) -> Vec<ExfiltrationIndicator>

Check text for data-exfiltration indicators (URLs, base64 blocks, etc.).

pub fn to_security_findings( &self, violations: &[McpSecurityViolation], ) -> Vec<SecurityFinding>

Convert a list of MCP violations into SecurityFinding values for the LLMTrace pipeline.

pub fn server_count(&self) -> usize

Number of registered servers.

pub fn tool_count(&self) -> usize

Number of tracked tool-to-server ownership entries.
