@followed by the MCP server name and your instructions, e.g., "@NamingSignalname ideas for a fitness app with domain checks"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
NamingSignal
Evidence-first product naming for agents and founders. NamingSignal generates broad, diverse name fields, checks exact domain registry evidence (RDAP) and developer namespaces, and researches finalists with sources and timestamps instead of vibes. Registry not-found is reported as likely unregistered, never as a purchase guarantee.
This repository contains the open-source clients and the deterministic naming core:
Package | What it is | Install |
Stdio MCP server exposing five read-only naming tools backed by the hosted API |
| |
CLI with keyless local commands (RDAP checks, privacy-bounded briefs, deterministic generation, decision records) plus hosted research |

Remote MCP, no install
The fastest integration is the hosted Streamable HTTP MCP endpoint. Create a free API key at https://namingsignal.com/developers/keys, then:
claude mcp add --transport http naming-signal https://namingsignal.com/mcp \
--header "Authorization: Bearer YOUR_NAMINGSIGNAL_KEY"Codex ~/.codex/config.toml:
experimental_use_rmcp_client = true
[mcp_servers.naming_signal]
url = "https://namingsignal.com/mcp"
bearer_token_env_var = "NAMING_SIGNAL_API_KEY"Prefer a local process? Use the stdio package instead; see packages/mcp.

Scope of this repository
This repo contains the MCP and CLI clients plus the deterministic core they share: RDAP domain checking with calibration, exact namespace checks (npm, PyPI, GitHub, Apple), the brief compiler, import safety bounds, the transparent scoring rubric, and decision-record export. The hosted orchestration (model-led generation, editorial ranking, finalist research providers, accounts, and metering) runs at namingsignal.com and is not in this repo.
