MCPCore is a browser-based platform that collapses the full lifecycle of Model Context Protocol server development — writing, testing, deploying, and managing — into a single interface. You describe what you want your MCP server to do in plain English, and an AI generates the server code. One-click deploy pushes it to an instant subdomain. No Dockerfile, no Kubernetes, no infrastructure decision-making. The platform covers four authentication modes (Public, API Key, OAuth 2.0, Bearer Token), AES-256 encrypted secret management for API keys and credentials your server needs at runtime, and ready-made configuration exports for every major MCP client: Claude Desktop, Cursor, VS Code, Windsurf, and Cline. A usage dashboard tracks calls, errors, and latency. The free tier allows one server and 10,000 calls per month. As MCP adoption accelerates — with Anthropic, OpenAI, and the Linux Foundation all standardizing around the protocol — the bottleneck is shifting from "what can MCP do" to "who can actually build and host MCP servers." MCPCore is a direct answer to that bottleneck: it brings MCP server creation within reach of developers who can write JavaScript but have never configured a cloud deploy pipeline.

Tendril
An agent that writes, registers, and reuses its own tools — forever

Tendril is an open-source desktop agent built on a radically minimal architecture: instead of giving an AI model dozens of pre-built tools, it gives the model exactly three — search capabilities, register capabilities, and execute code. When you ask it to do something it can't yet do, it writes the tool, registers it, and runs it. The next time you ask for something similar, the tool already exists. Built with Tauri, React, and Node.js on the frontend, and AWS Bedrock (Claude) for inference, Tendril runs code in sandboxed Deno environments for safety. The capability registry grows organically across sessions, meaning the agent becomes measurably more capable the longer you use it — without any retraining or fine-tuning. The "too many tools" problem is a real issue in production agents: large tool lists degrade model reasoning and increase hallucination rates. Tendril's inversion of this pattern — grow tools from need, not configuration — is a genuine architectural contribution. It's MIT licensed and free to use, though AWS Bedrock access for Claude adds ongoing inference costs.
Reviewer scorecard
“Setting up a production MCP server with OAuth and encrypted secrets normally takes a day of DevOps work. MCPCore gets you there in 20 minutes with a browser. The auto-generated config exports for Claude Desktop and Cursor are a nice touch — it handles the part of MCP adoption that causes the most friction for non-infra engineers.”
“The bootstrap-three-tools architecture is elegant and addresses a real failure mode. Watching an agent build its own scraper and then reuse it 20 minutes later without being told to is genuinely impressive. The Deno sandbox makes it safe enough to experiment with seriously.”
“Vendor lock-in risk is real here. Your MCP servers live on MCPCore's infrastructure, which means if pricing changes or the service shuts down your integrations break. AI-generated server code is also a black box — when it fails at 3am you're debugging code you didn't write on infrastructure you don't control. For hobby projects it's fine; for production it needs scrutiny.”
“Self-written tools accumulate technical debt fast — a poorly written capability that gets reused across sessions can silently spread bad behavior. There's no audit trail or quality gate for registered tools, which is a serious concern in any shared environment.”
“MCP is becoming the HTTP of AI tool integrations — every LLM client will eventually speak it natively. The companies that win the MCP server hosting market will be analogous to early web hosts in the 90s. MCPCore is positioning early in a market that will be enormous once enterprise adoption kicks in.”
“This is a prototype of what persistent agent intelligence looks like: not a model that forgets between sessions, but one that accretes capability. The capability registry pattern will likely influence how production agent systems are architected in the next two years.”
“Content teams increasingly want to give their Claude or Cursor setups custom data sources — CMS access, brand asset libraries, analytics feeds. MCPCore makes that possible without needing a backend engineer. Describe your data source, deploy, paste the config into Claude Desktop — that's the abstraction level creators actually need.”
“Requires AWS Bedrock setup, a Tauri desktop build, and comfort with the idea that your agent is writing its own code. That's three friction points too many for most non-developers. The concept is brilliant; the UX isn't there yet.”
