Sonatype MCP Server

Exposes Nexus Repository Manager REST API endpoints through the Model Context Protocol, allowing LLM agents to query artifact repositories, browse component metadata, and retrieve dependency information without direct API knowledge. Implements MCP resource and tool abstractions that translate natural language requests into authenticated Nexus API calls, handling pagination and response marshaling automatically.

Exposes Sonatype Repository Firewall policy evaluation capabilities through MCP tools, allowing LLM agents to check components against security policies, retrieve policy violation details, and understand remediation requirements. Translates Firewall policy rules and threat intelligence into queryable MCP tools that agents can invoke to validate artifacts before deployment or integration.

Coordinates multi-step remediation workflows through MCP by combining artifact inventory queries, policy violation detection, and version analysis to recommend and execute dependency updates. Uses planning and reasoning patterns to decompose remediation tasks (e.g., 'update vulnerable log4j to safe version') into sequences of Nexus queries and Firewall checks, with agent-driven decision-making at each step.

Queries Nexus Repository Manager to reconstruct component dependency graphs and analyzes impact of policy violations or version updates across the dependency tree. Uses graph traversal patterns to identify transitive dependencies, calculate blast radius of security issues, and recommend updates that minimize compatibility risk. Exposes dependency relationships as queryable MCP resources for agent-driven analysis.

Manages authentication to Nexus Repository Manager through MCP, supporting multiple credential types (username/password, API tokens, certificate-based auth) with secure storage and rotation. Implements credential abstraction layer that handles token refresh, expiration detection, and fallback authentication methods, allowing agents to interact with Nexus without managing credentials directly.

Normalizes and enriches artifact metadata from Nexus Repository Manager by parsing component coordinates, extracting version information, and augmenting with additional context (e.g., license information, security scores). Implements metadata transformation pipeline that converts raw Nexus API responses into structured, agent-friendly formats with consistent field naming and type coercion.

Generates detailed audit trails and compliance reports for policy violations detected by Repository Firewall, including violation history, remediation actions, and policy change tracking. Implements structured logging and report generation that captures who/what/when/why for each policy evaluation and remediation decision, enabling compliance audits and forensic analysis.

Enables cross-repository artifact search through MCP by querying multiple Nexus repositories simultaneously and aggregating results with deduplication and relevance ranking. Implements search abstraction that supports multiple query types (by name, coordinate, checksum, license) and returns unified result sets with repository source tracking for disambiguation.
