Then ask your AI: use ESG Hub to get server info

Install ESG Hub — Open-Access ESG Encyclopedia

The server’s own address, for the clients that take one directly. Or connect ahel once and every client you use reads it from one address, with the account kept on ahel rather than in each client’s config.

  • Claude Code

    claude mcp add --transport http --scope user esg-hub-open-access-esg-encyclop 'https://esg-hub.ascent.partners/api/mcp'

    Run it once in your project, then open /mcp to approve any sign-in the server asks for.

  • Claude Desktop

    https://esg-hub.ascent.partners/api/mcp

    Add a custom connector in Settings, paste this address, and approve the sign-in.

  • Cursor

    cursor://anysphere.cursor-deeplink/mcp/install?name=esg-hub-open-access-esg-encyclop&config=eyJ1cmwiOiJodHRwczovL2VzZy1odWIuYXNjZW50LnBhcnRuZXJzL2FwaS9tY3AifQ==

    Open the link and Cursor adds the server at that address.

  • ChatGPT

    https://esg-hub.ascent.partners/api/mcp

    In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.

  • Codex

    codex mcp add esg-hub-open-access-esg-encyclop --url 'https://esg-hub.ascent.partners/api/mcp'

    Run it once, then sign in with codex mcp login esg-hub-open-access-esg-encyclop if the server asks for an account.

Quick start

git clone https://github.com/simonplmak-cloud/esg-hub.git
cd esg-hub
pnpm install        # note: requires sibling repo ../tool_package (private)
cp .env.example .env  # fill in your own values
pnpm dev

Useful commands: pnpm lint · npx tsc --noEmit · npx vitest run · pnpm verify:db

Note: the app renders content from a SurrealDB database — you need your own instance and content to run a full copy. The public site and API are freely accessible without running anything.

API & MCP

  • REST API: open, no auth — GET /api/v1/pages, /api/v1/search?q=..., /api/v1/resources, /api/v1/meta (docs)
  • MCP server: see mcp-server/ — gives AI agents tools to search and read the knowledge base
