Overview

AI-generated overview

Crimson Crawler gives an assistant typed tools to enrich, search, assess, and manage threat intelligence through a hosted remote endpoint.

What you can do
Crimson Crawler is a remote MCP server that exposes over 80 typed tools for threat intelligence work. According to its registry description, these tools let an assistant enrich indicators, search intelligence data, assess findings, and manage related records. The manifest does not list individual tool names, so the exact operations are not documented here.
When to use it
Consider it when an assistant needs to look up or enrich threat intelligence as part of security analysis, incident triage, or research. It is a hosted service, so it suits users who want threat data without running a local process.
Requirements
A remote MCP client that supports streamable HTTP, plus a Crimson Crawler account and API key. The key is supplied through the apikey header, and OAuth authentication is required. Network access to the provider endpoint is needed.
Before you install
The server requires an API key sent in the apikey header, so treat that credential as a secret and avoid exposing it in logs or shared configuration. The description mentions managing threat intelligence, which may include write or delete operations; confirm what the tools change before granting access. Data submitted for enrichment or search is sent to the third-party provider.

Installation

In SourceWeft

  1. Open Crimson Crawler in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.crimsoncrawler%2Fmcp-server/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
