When to use it
Useful when classifying UK businesses by industry, translating between SIC and GICS/ICB taxonomies, or finding UK companies by code or name for research, onboarding or reporting.
Requirements
Runs as a remote endpoint at siccodes.co.uk or as a local npm package (sic-codes-mcp) over stdio. No authentication, environment variables or headers are declared.
Before you install
Company data comes from Companies House and is sent to the server operator when using the remote endpoint; check that this is acceptable for your data. Verify code mappings and company details before relying on them for compliance or reporting.

Installation

In SourceWeft

  1. Open SIC Codes UK in the dashboard and add it to a workspace.
  2. 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/io.github.jackmmaher%2Fsic-codes/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

60% of the applicable checks met

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.
