Instavar MCP server

Which MCP servers are Instavar's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.instavar/mcp-serververified in the MCP registry

The registry name sits under instavar.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

  • Stateanswerschecked 2026-10-27
  • Tools20
  • Server calls itselfinstavar-remotion
  • Server version1.6.0
  • Protocol version2025-06-18

On 2026-10-27 the server answered initialize and tools/list without a sign-in. First answer in 412 ms.

Should an agent connect itNot proven either way yet
  • Whether its tools do the product's job has not been judged yet.
  • Checked on 1 of the 7 days it takes to judge reliability.

Once connected

  • For "turn an answer or set of notes into a short video", the likely first call is propose_video_storyboard.
  • create_video_brief change data without a sign-in: anyone with the address can call them.
  • Parameters are untyped or undescribed in 13 of 20 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

What an agent can do with it

  • not sure · choose which content idea is worth testing next
  • can do · turn an answer or set of notes into a short video
  • not sure · render videos locally from code with an open-source template

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

  • Tools that change data, on a server that answers without a sign-in: create_video_brief

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "instavar": {
      "type": "http",
      "url": "https://instavar.com/api/mcp/templates"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http instavar https://instavar.com/api/mcp/templates

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://instavar.com/api/mcp/templates as a custom connector in the settings.

Also shipped through: npm

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
