Docs

Mostly Tiny products are independent tools that share three things: one account, one bill, and one agent surface (MCP). This is how those cross-product systems work. For a specific tool's API, see that product's own docs.

One login — Sign in with Mostly Tiny

Every product uses a single identity. Create a Mostly Tiny account once and Sign in with Mostly Tiny works across MostlyQR, MostlyPDF, MostlyRender, MostlyPrivacy and MostlySign — no separate account per tool.

Identity is issued by MostlyID (id.mostlytiny.io). Each product still keeps your data in its own project, so a product can be used — or exported — on its own.

One bill — the shared wallet

Billing is shared across the suite: one payment method and one prepaid balance cover whatever mix of tools you use, instead of a subscription per product.

Metered and agent usage draws on the shared wallet — add a card once at id.mostlytiny.io/billing and every metered tool across all products works. It is prepaid with optional auto-recharge, so spend is hard-capped — an agent can never run up a surprise bill. Free-tier allowances apply first.

The MCP — Mostly Tiny for AI agents

One MCP server fronts the whole suite: install it once and an AI agent can render images and PDFs, mint dynamic QR codes, generate privacy documents and more. Tools are generated from each product’s published OpenAPI, so they never drift from the real API.

Endpoint

https://mcp.mostlytiny.io — hosted, OAuth 2.1. Add it by URL and sign in with your Mostly Tiny account in the browser; no API key to manage.

Install

Claude Code

code
claude mcp add --transport http mostly-tiny https://mcp.mostlytiny.io

Claude (app + desktop) — add a Connector by URL (https://mcp.mostlytiny.io) and sign in.

ChatGPT — add it as an app/connector (Apps SDK) by the same URL.

OpenAI Codex — in ~/.codex/config.toml:

code
[mcp_servers.mostly-tiny]
command = "npx"
args = ["-y", "mostlytiny-mcp"]

Tools

  • mostlytiny_catalog — discover every product and whether it is enabled.
  • search / fetch — find a capability, then pull its detail.
  • <product>_<operation> — e.g. mostlyrender_render, generated per product.

Billing

Metered tools charge the shared wallet (see One bill). The catalog advertises each product’s per-call price so an agent (or you) can predict spend.

Per-product APIs & docs

Each product also ships its own REST API and documentation — the MCP builds its tools from these same specs. For endpoints, parameters and examples, see the product docs:
