MCP server

The server speaks MCP over Streamable HTTP at https://www.upgrow.com/mcp. It is stateless: every request is one JSON-RPC message answered with one JSON response. No key is needed.

Add it to an MCP client as a remote server. For clients that read a JSON config:

{
  "mcpServers": {
    "upgrow": {
      "type": "http",
      "url": "https://www.upgrow.com/mcp"
    }
  }
}

With the Claude Code command line:

claude mcp add --transport http upgrow https://www.upgrow.com/mcp

Tool	What it returns
`list_plans`	Basic, Pro and Turbo with the first-month price, what each includes and the sign-up link
`list_products`	The one-time shop products with tiers, starting prices and product page links (optional `platform`: `instagram` or `tiktok`)
`list_free_tools`	The free Instagram tools with a link and one-line description
`search_blog`	Blog posts matching `q` (2 to 100 characters), up to `limit` results (1 to 10)
`get_company_facts`	What UpGrow is, how it works, guarantees and support contacts
`get_signup_link`	The link where a user starts, plus the pricing and shop pages

Each tool returns readable text and structuredContent. Try it from a terminal:

curl -s https://www.upgrow.com/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"list_plans","arguments":{}}}'

The server card describes the endpoint. A GET request to /mcp returns 405 because the server opens no event stream.

A2A agent

The agent card is at https://www.upgrow.com/.well-known/agent-card.json. Send JSON-RPC to https://www.upgrow.com/a2a. The agent answers at once with a message that holds a text part and a data part.

It handles five kinds of questions: plans and pricing, the one-time shop, free tools, blog articles, and getting started. It accepts SendMessage (A2A 1.0) and message/send (A2A 0.3).

curl -s https://www.upgrow.com/a2a \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"SendMessage","params":{"message":{"messageId":"m-1","role":"ROLE_USER","parts":[{"text":"What does UpGrow cost?"}]}}}'

REST API

Base address: https://www.upgrow.com/api/public/v1. Responses are JSON, allow any origin (CORS) and are cacheable, except /health. The full description is in openapi.json.

Request	Returns
`GET /plans`	Basic, Pro and Turbo: first-month price, what each includes, sign-up link
`GET /products`	One-time shop products with tiers, starting prices and product page links
`GET /free-tools`	Free Instagram tools: name, link, one-line description
`GET /blog/search?q=&limit=`	Blog posts matching `q` (2 to 100 characters); `limit` 1 to 10, default 5; a bad value returns 400
`GET /health`	`{"status":"ok"}`, never cached

curl -s https://www.upgrow.com/api/public/v1/plans

curl -s 'https://www.upgrow.com/api/public/v1/blog/search?q=instagram%20reels&limit=3'

curl -s https://www.upgrow.com/api/public/v1/products
curl -s https://www.upgrow.com/api/public/v1/free-tools
curl -s https://www.upgrow.com/api/public/v1/health

In the browser (WebMCP)

In browsers that support WebMCP, UpGrow pages register tools an agent can call while the user watches: get_plans, list_products, search_blog, list_free_tools, open_signup and open_page (pages on www.upgrow.com only). Other browsers download nothing extra.

Discovery files

Agents and crawlers can find all of the above without reading this page:

https://www.upgrow.com/.well-known/api-catalog: API catalog (RFC 9727)
https://www.upgrow.com/.well-known/ai-catalog.json: catalog of the MCP server, A2A agent, OpenAPI document and skills
https://www.upgrow.com/.well-known/mcp/server-card.json: MCP server card
https://www.upgrow.com/.well-known/agent-card.json: A2A agent card
https://www.upgrow.com/.well-known/agent-skills/index.json: agent skills index
https://www.upgrow.com/.well-known/poppy.json: organization discovery file
https://www.upgrow.com/openapi.json: OpenAPI 3.1 description
https://www.upgrow.com/llms.txt: plain-text site map for language models

The home page also sends a Link header that points to the API catalog, the OpenAPI document, this page, llms.txt and the health endpoint.
