Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"polardbx-zero-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# PolarDB-X Cloud Zero MCP Server Give any AI agent persistent MySQL databases through the Model Context Protocol. Supports **multiple simultaneous instances** — create, manage, and query several databases at once. ## How It Works ``` ┌──────────────┐ MCP (stdio/http) ┌──────────────────┐ │ AI Agent │ ◄──────────────────────────► │ MCP Server │ │ (Qoder, etc) │ │ (this project) │ └──────────────┘ └────────┬─────────┘ │ MySQL protocol │ Zero API (HTTP) (pymysql + SSL) │ (on-demand creation) │ ┌────────▼─────────┐ │ PolarDB-X Cloud │ │ Zero │ └──────────────────┘ ``` 1. Agent calls `create_instance()` to create one or more databases (or provide credentials via env vars) 2. Server registers instances in a local registry (`~/.polardbx-zero-mcp/instances.json`) 3. All tools require an explicit `instance_id` — use `list_instances()` to discover them 4. SQL is executed over the **MySQL wire protocol** (pymysql + SSL) ## Installation ```bash pip install polardbx-zero-mcp ``` ### IDE / MCP Client Configuration **Claude Code:** ```bash claude mcp add polardbx -- polardbx-zero-mcp ``` **Qoder / Cursor / Windsurf / Claude Desktop** — add to mcp.json: ```json { "mcpServers": { "polardbx": { "command": "polardbx-zero-mcp" } } } ``` ### From source ```bash git clone https://github.com/polardb/polardbx-zero-mcp.git cd polardbx-zero-mcp pip install -e . polardbx-zero-mcp ``` > HTTP transport: `polardbx-zero-mcp --transport http` (default `http://localhost:8000/mcp`) ## Configu…
