OTInstaller MCP server

Which MCP servers are OTInstaller'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.otinstaller/registryverified in the MCP registry

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

On 2026-10-28 the server answered initialize and tools/list without a sign-in. First answer in 210 ms.

  • Its tools do none of the product's use cases we checked: store API keys for OSINT tools in one file; review saved tool results sorted by time.
  • Checked on 6 of the 7 days it takes to judge reliability.

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.

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

None of the five warning signs in these definitions.

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 →

  • search_tools

    Search the registry's OSINT tools by words, the input type they take, the entity type they find, or category. passive_only keeps the tools ot runs without asking the person.

  • get_tool

    A tool's inputs, outputs, API keys, network access and ethics flags, the consent class `ot mcp` will put a run in, what a run does in plain words, and how to install and run it with ot.

  • list_types

    The input types tools take, the entity types they find, the categories, and which input types each entity type can feed (the pivot map).

  • suggest_pivots

    For entity types found so far (a subdomain, an account, an email ...), the tools that take them as input, best first.

  • search_guides

    Search the registry's investigation guides (methods, checklists, references) by words, target type or level.

  • read_guide

    One page of a guide, as Markdown, with the list of its pages and the tools it uses.

How to connect

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

{
  "mcpServers": {
    "registry": {
      "type": "http",
      "url": "https://api.otinstaller.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

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

Add to CursorAdd to VS Code

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

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.
