May 2026 delivered impactful platform improvements in harness/mcp-server, focusing on global templates, API routing, and build stability. The team implemented global templates access with correct organization context, improved request routing with a routingId parameter, and stabilized the codebase by isolating schema types from auto-sync churn. These changes reduce misrouted requests, ensure correct template scoping, and enhance long-term maintainability while preserving existing test guarantees.

April 2026 (2026-04) MCP Server maintenance focused on configuration modernization and stability. Delivered Harness Configuration Constants Modernization by replacing deprecated HARNESS_DEFAULT_ORG_ID and HARNESS_DEFAULT_PROJECT_ID with canonical HARNESS_ORG and HARNESS_PROJECT, aligning with updated configuration schemas and improving code clarity. Included test updates to validate new field names and maintain compatibility. This change reduces misconfiguration risk and supports smoother deployments. Commit ef98f364927b92d9c0029d96a6c1d3b49700032d and subsequent test fixes (da3470, 28818e). Overall impact: improved stability, readability, and future-proofing of configuration handling.

March 2026 (2026-03): Focused on business value through stability fixes, incremental authentication improvements, and enhanced developer onboarding. JWT-based authentication work was reverted to maintain compatibility, but the groundwork, tests, and architectural groundwork informed future secure auth paths. Implemented per-request account ID resolution in HarnessClient, improved header handling to avoid downstream conflicts, and refreshed documentation. Security hardening and robust testing now underpin ongoing improvements.

December 2025 (harness/mcp-server): Delivered a bug fix and governance improvement with clear business value. Replaced config.AccountID with scope.AccountID in GetDatabaseInfo and SCS tool calls to ensure correct account identification in database and artifact source operations; updated CODEOWNERS to include an additional owner to strengthen code-review accountability. Impact: improved data accuracy, governance, and collaboration, with traceable changes across tool calls and ownership.

November 2025 (2025-11) delivered a focused set of enhancements to harness/mcp-server that improve modularity, developer experience, and reliability. Key work includes cross-module prompt registration for the HTTP MCP server, streamlined local development with a ready-to-use setup and logging defaults, comprehensive documentation for setup and configuration, and strengthened chatbot reliability through source-link enforcement. Targeted local deployment fixes further stabilized Kubernetes workflows. The work aligns with business goals of faster onboarding, improved traceability, and higher production reliability.

October 2025 MCP Server — concise monthly summary highlighting delivered features, major fixes, impact, and tech skills demonstrated. Focused on strengthening security, observability, configurability, and maintainability across the HTTP MCP server with a performance-conscious approach.

September 2025 monthly summary for harness/mcp-server focused on security, reliability, and developer experience. Delivered internal server mode with authentication for isolated testing and modular config management. Fixed critical initialization and data mapping issues to ensure robust startup and correct data serialization. Implemented backend stability and tooling enhancements including a license client factory, toolset mapping, IDP toolset logging/registration, improved HTTP auth middleware, and VS Code debugging support to streamline development and CI. These changes reduce deployment risk, accelerate issue resolution, and improve security posture and maintainability.

August 2025 MCP-server delivery focused on expanding tooling, improving testability and logging, and fixing API surface issues. The month delivered a cohesive set of enhancements that enable better connector management, observability, and module extensibility while keeping code quality high through automated testing and formatting discipline.

July 2025 monthly summary focused on improving developer onboarding, governance, and reliability for MCP-related tooling and services. Key outcomes include establishing governance with CODEOWNERS and standardized PR templates, correcting MCP server clone instructions to ensure reliable onboarding, and fixing pipeline log downloads when deployed behind gateways. These changes reduce onboarding time, improve code quality and collaboration, and enhance operational resilience for MCP tooling.

Month: 2025-06. This period delivered a major MCP Server API overhaul for Infrastructure, Services, and Environments, introducing new capabilities for managing services, environments, and infrastructure within the MCP server. The refactor removes legacy policy and GitOps functionality and adds new data types and APIs for GitOps, infrastructure, policy, services, and environments, while updating client configurations and dependencies. In addition, code formatting tooling was integrated into the build process (goimports and gci) via Makefile to improve code consistency and maintainability across the Go project. No explicit bug fixes are documented in the data; however, architectural changes and tooling updates reduce defect surface and improve stability. The combination of API modernization and build hygiene establishes a foundation for faster feature delivery and easier maintenance going forward.

Month 2025-03: Streamlined Custom Stage Deployment Options in harness-schema to expose only supported deployment strategies, reducing configuration confusion and preventing errors. Removed unsupported steps (ASG, SAM/Serverless, Google Cloud Run, Azure Functions) from the custom stage configuration.

February 2025 (2025-02) highlights the delivery of robust error reporting and comprehensive validation utilities for AI-driven pipeline generation in harness/harness. The work improves observability, reliability, and safety of automated pipeline creation by propagating LLM and AI generation errors into stage/step generation responses and by introducing validation utilities that prevent invalid pipeline configurations. These changes reduce debugging time, enable faster issue diagnosis, and establish a solid foundation for scalable AI-assisted pipeline orchestration.

January 2025 performance summary for harness/harness focused on delivering AI-enabled DevOps capabilities and strengthening data integrity for automated pipelines. Key work centered on enabling AI-driven, conversation-aware updates to pipeline steps, and stabilizing data formats and labeling to prevent processing errors across stages.

December 2024 summary for harness/harness focused on API stability, pipeline automation, and maintainability improvements within Harness Intelligence.
