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":"grpcurl-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# grpcurl MCP Server MCP server that wraps [`grpcurl`](https://github.com/fullstorydev/grpcurl) for calling gRPC APIs. ## Tools - **`grpc_invoke`** — Execute a gRPC method. Parameters: `url` (required, e.g. `host:443`), `endpoint` (required, e.g. `ProductService.GetProducts`), `payload` (required, JSON request body). - **`grpc_list_services`** — List services available on a gRPC server. Parameters: `url` (required). ## Requirements - Python 3.11+ - [uv](https://docs.astral.sh/uv/) - [`grpcurl`](https://github.com/fullstorydev/grpcurl) on PATH Install `grpcurl`: **macOS (Homebrew)** ```bash brew install grpcurl ``` **Linux** ```bash # Debian/Ubuntu sudo apt install grpcurl # Or download the latest binary from GitHub releases curl -sSL https://github.com/fullstorydev/grpcurl/releases/latest/download/grpcurl_linux_x86_64.tar.gz | tar -xz sudo mv grpcurl /usr/local/bin/ ``` **Windows (Scoop)** ```powershell scoop install grpcurl ``` **Go (any platform)** ```bash go install github.com/fullstorydev/grpcurl/cmd/grpcurl@latest ``` Verify the install: ```bash grpcurl --version ``` ## Install The recommended way is via `uvx` — no separate install step needed: ```json { "mcpServers": { "grpcurl": { "command": "uvx", "args": ["grpcurl-mcp"] } } } ``` `uvx` fetches and runs the package from [PyPI](https://pypi.org/project/grpcurl-mcp/) automatically. Or install explicitly with pip: ```bash pip install grpcurl-mcp ``` ## Claude Code setup Run this command to register the server (one-time setup): ```bash claude mcp add grpcurl -- uvx grpcurl-mcp ``` Or add it manually to your Claude Code MCP config (`~/.claude/settings.json` or project `.claude/settings.json`): ```json { "mcpServers": { "grpcurl": { "command": "uvx", "args": ["grpcurl-mcp"] } } } ``` ## Cursor setup Edit `~/.cursor/mcp.json` (global) or `.cursor/mcp.json` (project-level) and add: ```json { "mcpServers": { "grpcurl": { "command":…
