ToolPiper

Streamable HTTP(zero config — loopback connections need no auth):

claude mcp add --transport http toolpiper http://127.0.0.1:9998/mcp

{ "mcpServers": { "toolpiper": { "type": "http", "url": "http://127.0.0.1:9998/mcp" } } }

stdio(the~/.toolpiper/mcpsymlink is created automatically on launch):

claude mcp add toolpiper -- ~/.toolpiper/mcp

{ "mcpServers": { "toolpiper": { "type": "stdio", "command": "/Users/<you>/.toolpiper/mcp" } } }

300+ tools, 5 resources, and 5 workflow prompts. Names follow<category>_<action>(vision_ocr,system_window_snap,browser_assert). The full catalog ships names-only on the wire (~24 KB), so it fits under Claude Code's per-server payload cap without trimming.

Resources:toolpiper://status,toolpiper://models,toolpiper://backends,toolpiper://tests,toolpiper://categoriesPrompts:setup-model,audit-page,create-test,voice-over,research-topic

Don't want all 300 tools in context? Filter at connect time — both the tool list and the server instructions trim to match:

ToolPiper never calls out. No telemetry, no analytics, no crash uploads, no account requirement. The only network traffic is the traffic you ask for (model downloads from HuggingFace, tools that explicitly target the web). This is a property you can check, not a policy you have to trust:

Is this the same as "ToolPipe"?No. ToolPiper (this page,modelpiper.com) is the macOS MCP server by ModelPiper. Unrelated projects with similar names exist in some directories.

What does the MIT license in this repo cover?The contents of this repository — the server manifest, setup guides, and recipes. The ToolPiper app itself is proprietary (free tier + Pro).

Does it work without an internet connection?Yes — inference, voice, vision, RAG, and system tools are all on-device. You only need the network to download models.

Can other machines connect?Loopback is zero-config. LAN/remote access goes through bearer-token auth.

This is a web browser that enables your coding agent, such as Claude Code, to visit websites on your behalf and assist you in identifying bugs or creating UI test cases.
