Don't want to enter an API key? Bring the AI you already pay for. MCP (Model Context Protocol) is now the industry-wide open standard — governed by the Linux Foundation and adopted by Anthropic, OpenAI, Google, Microsoft, xAI, and more — so Claude, ChatGPT, Copilot, Grok, Gemini, and any other MCP-capable client can drive Just Signal directly. Your subscription's model does the research and writing; Just Signal supplies what it uniquely owns — live Day-0 price grounding, mechanical dollar-target math, transmission stamps, publishing to the public library, and The Chophouse's panel-graded menu. No API key is ever entered, and generation costs you nothing beyond the subscription you already have.
Web-based AI apps can't run local programs, so they connect to our hosted MCP endpoint. Add this URL wherever your AI app configures connectors:
| Your AI | Where to add it | Status |
|---|---|---|
| Claude (claude.ai / Desktop) | Settings → Connectors → Add custom connector → paste URL | ✅ Remote connectors (Pro/Max/Team/Enterprise) |
| ChatGPT | Settings → Connectors (enable Developer Mode) → New connector → paste URL | ✅ Plus / Pro / Business / Enterprise |
| Microsoft Copilot | Copilot Studio → your agent → Tools → Add MCP server → paste URL | ✅ Copilot Studio (consumer Copilot rolling out) |
| xAI Grok | grok.com → Connectors → add remote MCP → paste URL | ✅ Paid Grok accounts |
| Google Gemini | Gemini CLI: add an httpUrl MCP entry · Gemini Enterprise: admin connectors | ✅ CLI & Enterprise · consumer app in beta |
| Meta Llama | No MCP in the Meta AI app — use the paste-back publisher on app.html (generate, paste the JSON block, published), or run Llama in an MCP-capable client (LM Studio, Ollama + an MCP client) | ⚠ Paste-back / open clients |
| DeepSeek | No MCP in the chat app — use the paste-back publisher on app.html: generate there, paste the JSON block it returns, published | ⚠ Paste-back |
| Poe (Quora) | No MCP on poe.com — either the paste-back publisher on app.html, or the deepest cut: a key from poe.com/api_key on the app's api-key path, powered by your existing Poe points across 200+ models | ⚠ Paste-back / Poe points |
| Perplexity / Mistral / others | Their connector settings → paste URL; no connector offered? The paste-back publisher on app.html works for every chat | ✅ Where MCP connectors are offered |
| Any AI, no connector at all | The universal fallback: on app.html pick your provider, generate, then paste the JSON block your AI returns — one click publishes it through this same open endpoint (rate-limited) | ✅ Works everywhere |
The hosted endpoint exposes all five tools openly, including publish_report. Community publishing needs no key and no token: the server itself grounds every Day-0 price and renders every page, so the only thing anyone can add to the library is a genuine Just Signal report. To keep it fair, tokenless publishing is rate-limited (a few reports per connection per day, plus a global daily budget); read tools are never limited.
Clients that can launch local programs get the full experience, including publishing, from a tiny open-source package that runs on your machine. It is on npm, so for Claude Code there is nothing to download:
npx always pulls the latest published version, so there is nothing to install or update by hand.| Tool | What it does |
|---|---|
| get_stock_quote | Live price + % change via Just Signal's market-data relay; establishes a ticker's Day-0 baseline. |
| publish_report | The big one: grounds every ticker's Day-0 price, computes exact dollar targets from your model's percentage projections, renders the full report (with Go-Ahead / Over-&-Out / Time-Out stamps and Chophouse grading data), and publishes it to Past Transmissions. Returns the live URL. |
| list_reports | Browse the public library. |
| get_scorecard | Audit every signal: the whole ticker registry graded by the unified verdict cascade (projection, then direction, then return) against the daily snapshot, matching the site exactly, with the Chophouse doneness grade folded in. |
| get_panel_grade | The Investment Panel's read on any ticker: its Chophouse doneness grade (RAW to CHARRED) plus every seat's vote across 11 emulated investor lenses. The panel advises; the reader decides. |

Private companies or no ticker? Use (PRIVATE) and that trend honestly displays relative basis. Published reports are public — they join the same library, sitemap, and Chophouse as every other transmission.
