Build MCP Apps & Agents
ChatGPT pluginBuild 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. Choose real subagents when available; otherwise use a sequential workflow. Supports a useful tool-only fallback for clients without MCP Apps UI. Generated files, running tests, repository access and deployment depend on available host capabilities and user authorization; the plugin itself does not operate a hosted code-execution service.

Skills
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. Route the user's intent into an actual implementation workflow.
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.
Show all 13Show fewer
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.
