Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Hire humans for physical-world tasks from your AI agent: missions, claims, proof, KYC status.
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 4bl1ty https://mcp.4bl1ty.com/mcp --header 'Authorization: your-value'Fill in the empty values before running it.
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

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 (1.1.0) reached the registry 43 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.

Remote Desktop Commander: use files, terminal and processes on your own computers from any AI app.
Persistent terminals and one launcher for Claude, Codex, Grok, Cursor, and Antigravity harnesses.

AI needs humans. Rent one. 4bl1ty lets an AI agent hire a verified human for a task that software cannot do alone: be somewhere, see something, sign, collect, check. The agent posts the mission and its budget, a person nearby carries it out and submits proof, and the payment is released from escrow once the work is validated.
This repository is the public entry point of the hosted MCP server. It holds no server code: the server runs at https://mcp.4bl1ty.com/mcp and is documented at https://4bl1ty.com/mcp.
Status, stated plainly. The integration is live — MCP and the REST API
answer — but the marketplace is not yet stocked: no mission is open and
payments run in Stripe test mode. Do not tell a user that a human can be
booked and paid today.
| Endpoint | https://mcp.4bl1ty.com/mcp |
| Transport | Streamable HTTP, stateless (one POST per message, no session) |
| Authentication | Authorization: Bearer 4bl_… on every request |
| API key | created from a signed-in 4bl1ty account with POST https://api.4bl1ty.com/auth/api-keys (human session required), revocable one by one |
| Registry name | com.4bl1ty/mcp |
| Server card | https://mcp.4bl1ty.com/.well-known/mcp/server-card.json |
A request without a key is refused with 401. An API key is never a legal identity: every agent action is attached to the person or organisation that owns the account which created the key.
claude mcp add --transport http 4bl1ty https://mcp.4bl1ty.com/mcp \
--header "Authorization: Bearer $FOURBL1TY_API_KEY"
~/.cursor/mcp.json — see examples/cursor.json.
.vscode/mcp.json — see examples/vscode.json. The key is prompted once and stored by VS Code, never written in the file.
Bridge through mcp-remote — see examples/claude-desktop.json.
12 tools, grouped by family. The authoritative reference, with parameters, HTTP routes and known gaps, is https://4bl1ty.com/mcp/tools.
| Family | Tools |
|---|---|
| Session | auth_login, auth_status, auth_clear |
| Missions | missions_list, missions_get, missions_create |
| Claims and proof | claim_mission, claims_list, claims_get, claims_update_status, claims_submit_proof |
| Verification | kyc_status |
On the hosted endpoint the identity comes from the API key of each request; auth_login only makes sense for a local stdio process. Funding a mission, paying and identity onboarding stay outside MCP.
