Build MCP Apps from ideas
Design, implement, inspect and test MCP servers and interactive MCP Apps using focused skills for tool contracts, host-aware interfaces, secure integration, debugging, visual quality and release preparation. Start with an idea, API specification or repository; work through actual coding tools available in the host. More

Build from idea Build a complete MCP server or interactive MCP App from a natural-language idea or API brief, including source, real tests, and a runnable handoff where tools permit. Build mcp server Implement and test a real MCP server exposing tools and resources over a suitable transport, using current official SDKs and secure integration patterns. Build mcp ui Build a usable interactive MCP Apps UI with ui:// resources, host bridge, real tool interactions, accessible states and a useful text-only fallback. Debug mcp project Diagnose and fix a broken MCP server, UI bridge, authentication, transport, tools/list, tools/call or resource-rendering issue from errors, logs or code. Design mcp tools Design or improve useful MCP tools and resource contracts from a user's workflow, including schemas, authorization, side-effect hints, errors, pagination and tests. Get started Use MCP App Builder for a new MCP tool, interactive MCP App, API integration, or existing MCP project. Modernize mcp project Review, refactor or upgrade an existing MCP server or MCP App without breaking its API, user workflows or security boundaries. Orchestrate agents Coordinate genuine specialized coding, UX, security and verification subagents for a substantial MCP build when the host supports multi-agent delegation; fall back to one-agent execution otherwise. Plan mcp app Architect an MCP server or interactive MCP App from a user's idea, API concept, existing workflow, or product brief before writing implementation code. Prepare mcp release Prepare a generated MCP server or MCP App for user-approved deployment and review, including manifests, endpoint verification, security, test evidence and release notes. Review mcp design Review and improve the actual visual design, usability, accessibility and interaction states of an MCP App UI using the curated design reference library. Secure mcp server Threat-model and secure an MCP server or MCP App, including authentication, authorization, prompt injection, CORS, CSP, secrets and write confirmation. Test mcp project Validate an MCP server or MCP App with build checks, protocol-level tests, authorization negatives, UI lifecycle checks and honest evidence reporting.
