Features
Add an MCP server to any website with a single webmcp.js script tag
No backend or transport code — the page itself is the server
registerTool defines callable actions with a JSON schema for arguments
Example weather tool returns data for a supplied location
registerPrompt ships reusable prompt templates with required arguments
Git commit message prompt template that accepts a diff as a required argument
Code Explanation and Text Summarization prompt templates included
registerResource exposes page content or DOM elements by URI
registerResourceTemplate supports dynamic URIs such as element://{elementId}
Sampling requests LLM completions through the client via a user-approval modal
Blue corner widget shows connection state and accepts a pasted MCP token
Customize widget color, position, size and padding via constructor options
Works with any MCP client; setup documented for Claude Desktop
Connection flow: generate a webmcp token in your client, paste it into the widget
Dynamic tool registration after page load (client restart often required)
Durable execution captures Workflow state at every step with no checkpointing or recovery code
Native SDKs for Go, Java, Python, TypeScript, .NET, PHP, Ruby, and Rust
Activities retry automatically with backoff, four timeout classes, and heartbeating
Signals, Queries, and Updates read and mutate running Workflows mid-flight
Workflow Streams for real-time interactivity with running executions
Durable AI agents via OpenAI Agents SDK and Google ADK running LLM and tool calls as Activities
Serverless Workers host durable AI agents on Amazon Bedrock AgentCore
Serverless Workers on AWS Lambda (public preview) and GCP Cloud Run (pre-release)
Standalone Activities as a durable job-queue pattern, GA across six SDKs (2026-09-15)
Native Task Queue priority and fair distribution without a custom queueing layer
Durable Timers sleep for months; cron Schedules support backfill and Continue-As-New
Saga pattern via compensating transactions that read like try/catch
Worker Versioning pins Workflows to a version so deploys don't corrupt in-flight runs
Cloud UI Strict Session Mode enforces 15-min inactivity timeout and 12-hour max session (GA 2026-09-18)
Replay tests validate against real histories; time-skipping tests fast-forward long timers in CI

What real users say: WebMCP vs Temporal AI

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

WebMCP

72 mentions across 5 sources · 74% positive (weighted across 5 sources)

Hacker News, YouTube, Product Hunt, GitHub, Lemmy

What users praise

  • • One script tag turns any page into an MCP server with no backend or transport code
  • • Community consensus calls it simpler and more useful than full MCP for web apps
  • • Works with any MCP client, including Claude Desktop, via a pasted token
  • • Supports the full MCP surface: tools, prompts, resources, and sampling

What frustrates them

  • • Open GitHub issue reports auth tokens expire immediately after a single call
  • • Not battle-tested; docs themselves position it for demos rather than production traffic
  • • Docs recommend registering tools immediately, creating friction for dynamic single-page apps
  • • Community questions whether it beats Claude Code search or Playwright for browser automation
