NetSendo for AI agents

Public, read-only access to NetSendo product facts, plans, releases, documentation and blog articles: an MCP server, a REST API and Markdown versions of every page. No registration, no API key. Only the optional release-alert tools need an OAuth sign-in.

MCP server

Streamable HTTP endpoint https://netsendo.com/mcp, stateless, tools only. Add it to an MCP client:

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

Tool	What it returns
get_product_facts	Key facts about NetSendo: what it is, license (source-available EULA, not OSI open source), deployment with Docker, current version, AI and SMS providers, integrations, links and company details.
list_plans	NetSendo license plans with prices in USD and features: SILVER (free) and GOLD (per month), plus the planned cloud hosting fee. Link users to the url field for current details.
list_releases	Most recent NetSendo releases from GitHub, newest first, with date, highlights and release notes URL.
search_blog	Search NetSendo blog articles about email marketing, deliverability, automation and product updates by words in the title or excerpt. Returns slug, title, excerpt and url, newest first. Omit q to list the latest articles.
get_blog_post	Full text of one blog article as Markdown, by slug from search_blog. Falls back to English when the article has no translation in the requested locale. Cite the url field.
list_docs	Documentation pages: installation, configuration, API, webhooks, AI providers, MCP and n8n. Use get_doc with an id to read one.
get_doc	One documentation page as Markdown, by id from list_docs (e.g. "docs-quickstart"). English.

Release alerts (OAuth 2.1)

Three MCP tools act for one person: they manage NetSendo release alerts (one email per release) for the user's own email address, verified with an emailed code. They need an OAuth 2.1 access token; all other tools stay public.

Tool	Scope	What it does
get_my_release_alerts	alerts:read	Whether the signed-in user's email address is subscribed to NetSendo release alerts (one email per release). Requires OAuth scope alerts:read.
subscribe_release_alerts	alerts:write	Subscribes the signed-in user's own verified email address to NetSendo release alerts. Idempotent. Requires OAuth scope alerts:write.
unsubscribe_release_alerts	alerts:write	Unsubscribes the signed-in user's email address from NetSendo release alerts. Requires OAuth scope alerts:write.

Scopes: alerts:read (see whether your email address is subscribed to netsendo release alerts); alerts:write (subscribe your email address to netsendo release alerts or unsubscribe it).
Apps: dynamic client registration and authorization code with PKCE (S256). Metadata: https://netsendo.com/.well-known/oauth-authorization-server.
Agents: auth.md registration (service_auth or verified_email) at https://netsendo.com/oauth/agent/identity; the user approves with an emailed code and the agent's 6-digit code. Details in auth.md.
Protected resource metadata: https://netsendo.com/.well-known/oauth-protected-resource/mcp

REST API

Base URL https://netsendo.com/api/v1, JSON, CORS open, no authentication. Described in OpenAPI 3.1. This is the API of netsendo.com, not of a NetSendo installation; that one is documented in the API reference.

GET	Returns
/product	Product facts: license, deployment, current version, providers, integrations, links
/plans	Plans and prices in USD
/releases?limit=5	Latest releases from GitHub
/blog?q=deliverability&locale=en	Search blog articles (locale: en, pl, de, es)
/blog/{slug}	One blog article as Markdown
/docs	Documentation pages
/status	API status

Markdown versions of pages

Request any page with the header Accept: text/markdown to get its content as Markdown with front matter (title, URL, description, language). Browsers keep getting HTML.

curl -H "Accept: text/markdown" https://netsendo.com/en/docs/quickstart

In the browser (WebMCP)

Pages register read-only WebMCP tools (netsendo_product_facts, netsendo_plans, netsendo_search_blog) for agents running in a browser that supports document.modelContext.
