PROFILE
Sunil Gattupalle
Over three months, contributed to harness/mcp-server by delivering fifteen features and resolving critical bugs, focusing on backend development and API design using TypeScript and Node.js. Developed risk-based operation policies, dual pipeline versioning, and extensible schema registration to enhance governance, security, and developer productivity. Integrated AI-driven commit capabilities and improved authentication with multi-user support, while reorganizing schemas for versioning and validation. Enhanced diagnostic tooling, repository rules management, and log handling, ensuring robust error handling and comprehensive test coverage. Emphasized maintainability through technical documentation and structural validation, supporting enterprise readiness and enabling faster, safer adoption of pipelines, schemas, and AI workflows.

May 1, 2026May 2026 performance summary for harness/mcp-server: - Delivered a risk-based OperationPolicy framework that gates high-risk operations, adds retry semantics, auto-approval for low-risk actions, and a centralized multi-sink audit/logging system. This included backfilling operationPolicy across ~500 EndpointSpecs (31 toolsets), structural validation tests, and comprehensive design/docs coverage to improve maintainability and auditability. - Launched Dual Pipeline Version support with an examples registry and progressive discovery: added v0 and v1 pipeline templates, ResourceExample types, and discovery hooks so users can locate and adopt pipelines quickly via harness_describe. - Enriched Harness Schemas with Extensible registration: introduced additionalSchemas support and runtime registration hooks, enabling startup extension of schemas without core changes and with collision handling safeguards. - Enabled AI Agents to perform commits via the Harness Code API: added a complete commit create operation with a robust body schema and mapping to POST /code/api/v1/repos/{repoIdentifier}/commits, enabling AI-driven code changes without cloning. - Hardened HTTP MCP authentication with multi-mode deployment: introduced single-user and multi-user modes, enforced route-level authentication, added route-level tests, and updated docs to reflect safer, more scalable authentication patterns. Overall impact: these deliverables significantly raise safety, security, and governance while improving developer productivity and discovery of assets (pipelines, schemas, examples). The work underpins faster safe changes (auto-approval for low-risk actions), clearer auditability, and better support for AI-driven workflows and multi-tenant deployments. Technologies/skills demonstrated: policy-based security design (RiskLevel, RetryPolicy, OperationPolicy), registry and schema design, runtime extensibility (additionalSchemas), OpenTelemetry and centralized auditing concepts, secure authentication patterns (single/multi-user MCP), YAML-based workflow pipelines, and tooling for AI-assisted code operations.

Apr 1, 2026April 2026 MCP server: delivered extensible toolset registry with runtime injection, integrated AI Evals toolset with opt-in controls and new endpoints, fixed resource discovery to dynamically select the correct resource type based on HARNESS_PIPELINE_VERSION, and reorganized schemas into versioned directories with v1 support and enhanced validation. These efforts improve business value by enabling faster toolset adoption, reducing discovery errors, and strengthening governance and maintainability across pipelines and schemas.
