Obscurify.ai

Obscurify.ai MCP server

Give your AI agent private access to 200+ other models. This Model Context Protocol server lets Claude Desktop, Claude Code, Cursor, VS Code, Codex, opencode and any other MCP client ask Claude, GPT, Gemini, Llama, DeepSeek, Qwen and more through Obscurify.ai.

Obscurify.ai is a privacy-focused, OpenAI-compatible AI platform. Text requests only use zero-data-retention routes, prompts and responses aren't stored on its servers, and accounts are a random 16-digit account number with no email, phone or password.

Tools

Tool	What it does
ask	One prompt to any model, with an optional system prompt, reasoning_effort, max_tokens and temperature. Returns the reply plus model, tokens and cost.
chat	Multi-turn: pass the whole messages history and get the next reply.
second_opinion	The same prompt to 2-5 models in parallel, every answer side by side. Good for checking a claim, reviewing code or a plan, or breaking a tie.
list_models	Model IDs with context window, price per million input/output tokens, tool support and the plan each needs. Filter by name, plan, price or tool support. Works without a key.
generate_image	Text-to-image with Stable Diffusion models (SDXL, SD 1.5, LCM). Returns the image. list: true shows the models and prices.
balance	Balance, plan, usage this billing period, and whether the account can use frontier and uncensored models.

Defaults are cheap and fast: ask and chat use deepseek/deepseek-v4-flash, and second_opinion asks deepseek/deepseek-v4-flash, meta-llama/llama-3.3-70b-instruct and qwen/qwen3.8-27b. Pass model / models to use anything else, e.g. anthropic/claude-sonnet-5.5 or openai/gpt-5.5.

Get an API key

1. Create an account at obscurify.ai. You get a random account number: no email, no password.
2. Add a balance (card, Monero, Bitcoin or Lightning). The API works on every plan with a positive balance. Frontier models need the Casual plan or higher, and uncensored models need Pro (pricing).
3. On obscurify.ai/account, click Show API Key and copy the sk-obs1_... key.

Calls cost money from your balance at each model's listed price (model cards). Every reply shows what it cost.

Setup

The server runs with npx -y @obscurify/mcp (Node.js 20 or newer) and reads the key from OBSCURIFY_API_KEY.

Claude Code

claude mcp add obscurify -e OBSCURIFY_API_KEY=sk-obs1_... -- npx -y @obscurify/mcp

Add -s user to make it available in every project.

Claude Desktop

Settings → Developer → Edit Config, then add to claude_desktop_config.json:

{
  "mcpServers": {
    "obscurify": {
      "command": "npx",
      "args": ["-y", "@obscurify/mcp"],
      "env": { "OBSCURIFY_API_KEY": "sk-obs1_..." }
    }
  }
}

Restart Claude Desktop.

Cursor

Add the same mcpServers block to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

{
  "mcpServers": {
    "obscurify": {
      "command": "npx",
      "args": ["-y", "@obscurify/mcp"],
      "env": { "OBSCURIFY_API_KEY": "sk-obs1_..." }
    }
  }
}

VS Code (GitHub Copilot agent mode)

Create .vscode/mcp.json. VS Code asks for the key once and stores it securely:

{
  "inputs": [
    { "type": "promptString", "id": "obscurify-key", "description": "Obscurify.ai API key", "password": true }
  ],
  "servers": {
    "obscurify": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@obscurify/mcp"],
      "env": { "OBSCURIFY_API_KEY": "${input:obscurify-key}" }
    }
  }
}

Codex CLI

codex mcp add obscurify --env OBSCURIFY_API_KEY=sk-obs1_... -- npx -y @obscurify/mcp

or in ~/.codex/config.toml:

[mcp_servers.obscurify]
command = "npx"
args = ["-y", "@obscurify/mcp"]
env = { OBSCURIFY_API_KEY = "sk-obs1_..." }
# Optional: don't ask before each paid call (ask, chat, second_opinion, generate_image)
default_tools_approval_mode = "approve"

The tools that spend from your balance are marked as not read-only, so Codex asks before running them unless you set default_tools_approval_mode.

opencode

opencode mcp add obscurify --env OBSCURIFY_API_KEY=sk-obs1_... -- npx -y @obscurify/mcp

That writes this to opencode.json (add --global for your global config):

{
  "mcp": {
    "servers": {
      "obscurify": {
        "type": "local",
        "command": ["npx", "-y", "@obscurify/mcp"],
        "environment": { "OBSCURIFY_API_KEY": "sk-obs1_..." }
      }
    }
  }
}

Windsurf, Cline, Zed and other clients

Use the command npx -y @obscurify/mcp with the environment variable OBSCURIFY_API_KEY in the client's MCP settings.

Docker

docker build -t obscurify-mcp https://github.com/Obscurify-ai/obscurify-mcp.git
docker run -i --rm -e OBSCURIFY_API_KEY=sk-obs1_... obscurify-mcp

Streamable HTTP

For clients that connect over HTTP, run the server yourself:

OBSCURIFY_API_KEY=sk-obs1_... npx -y @obscurify/mcp --http --port 3000
# MCP endpoint: http://127.0.0.1:3000/mcp   health: /health

It binds to 127.0.0.1 unless you pass --host. Each request may carry its own key as Authorization: Bearer sk-obs1_..., which takes precedence over OBSCURIFY_API_KEY, so one server can serve several accounts. The HTTP mode is stateless.

Configuration

Variable	Default
OBSCURIFY_API_KEY	(none)	Your sk-obs1_... key. Without it only list_models and generate_image list work.
OBSCURIFY_DEFAULT_MODEL	deepseek/deepseek-v4-flash	Model for ask and chat when none is given.
OBSCURIFY_SECOND_OPINION_MODELS	deepseek/deepseek-v4-flash,meta-llama/llama-3.3-70b-instruct,qwen/qwen3.8-27b	Comma-separated models for second_opinion.
OBSCURIFY_BASE_URL	https://obscurify.ai/v1	API base URL.
OBSCURIFY_TIMEOUT_MS	180000	Per-request timeout. second_opinion caps each model at 55 s so the answers that do arrive come back.

Example prompts

• "Ask Gemini and GPT what they think of this migration plan, then summarise where they disagree." (second_opinion)
• "Find the cheapest model with tool calling and a 1M context." (list_models)
• "Have Llama 3.3 70B rewrite this paragraph for a general audience." (ask)
• "How much have I spent on Obscurify this month?" (balance)

Privacy

The server is a thin client: it sends your prompts to https://obscurify.ai with your key and nothing else. No telemetry, no logging to disk, no file access. What Obscurify.ai keeps is described in its privacy policy: prompts and responses are not stored, and identities are scrambled before requests reach model providers. Providers still see the prompt text, so don't send secrets you wouldn't send to the model itself.

Tested

On 2026-10-28 with a Pay As You Go key, every tool was called from MCP Inspector 2.12 (CLI), Claude Code 2.1, Codex CLI 0.165 (both from the local build and from npx -y @obscurify/mcp), and the SDK client in scripts/e2e.mjs over stdio and Streamable HTTP. opencode 2.1 connects and lists the tools.

Development

npm install
npm run build
OBSCURIFY_API_KEY=sk-obs1_... node scripts/e2e.mjs stdio --image   # live end-to-end test, costs well under a cent
OBSCURIFY_API_KEY=sk-obs1_... node scripts/e2e.mjs http
npx @modelcontextprotocol/inspector node dist/index.js

Releases: bump the version in package.json and server.json, then push a vX.Y.Z tag. The workflow publishes to npm with provenance and to the MCP Registry.
