Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Augment your work with Liminal. Stop repeating yourself and build on what’s already solved.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.

Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.
Run this in your terminal
claude mcp add --transport http liminality https://liminality.physea.ai/mcp --header 'X-API-Key: your-value'Fill in the empty values before running it.
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

"headers": {
"X-API-Key": "your-value"
}

}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.0.6) reached the registry 29 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Liminal turns objectives into structured work by strategizing through an atomic, deterministic basis: setting guardrails around scope, compiling resources and constraints, uncovering gaps, and organizing research and next steps. All while carrying continuity and priorities forward so your AI builds on what’s already done.
Connect easily through MCP or use the desktop app.
Remote server, nothing to build or run locally. Get a key at https://physea.ai/signup, then add it to your client. Ready-to-copy files for each client are in examples/, with a first solve walkthrough.
Claude Code
claude mcp add liminal --transport http https://liminality.physea.ai/mcp --header "X-API-Key: YOUR_KEY"
Cursor
Add to ~/.cursor/mcp.json:
{
"mcpServers": { "liminal": { "url": "https://liminality.physea.ai/mcp", "headers": { "X-API-Key": "YOUR_KEY" } } } }
VS Code
Add to .vscode/mcp.json:
{
"servers": { "liminal": { "type": "http", "url": "https://liminality.physea.ai/mcp", "headers": { "X-API-Key": "YOUR_KEY" } } } }
Docker (stdio bridge)
For clients or directories that need a container, the Dockerfile wraps the remote endpoint with mcp-remote:
docker build -t liminal-mcp . && docker run -i --rm -e API_KEY=YOUR_KEY liminal-mcp

Instead of answering from memory, it works out the structure of the request first, then routes each piece to something real.
It runs on context-dependent determinism. Same question with the same known context routes the same way every time, so a result is reproducible and you can hand the route to someone else and get the same thing back. Change the context, and the route adapts to it. The determinism is in how it decides, not a frozen cache of canned answers.
research runs a deeper multi-source pass that pulls real information for a question.ask_form / apply_form: when the answer depends on your specifics, it hands back a short multiple-choice form. Relay it, then apply_form folds the answers into a sharper result.get_my_context: what's known about you and what you've connected.register_asset / set_preference: tell it about your material and how you like results.report_feedback / report_outcome: tell it how a result did, so routes improve with use.composio_connect: connect a tool so an action can run against it.https://liminality.physea.ai/.well-known/mcphttps://liminality.physea.ai/.well-known/agent.jsonhttps://liminality.physea.ai/llms.txt© 2026 Physea Labs.
