# Damngoodsales > The MCP library for AI agents. An agent connects once to the Damngoodsales MCP gateway (OAuth 2.1). Every app the user owns adds its tools to that connection. Apps can be bought by people on the website or acquired by the agent over MCP; both land on the same account. Free apps unlock instantly, paid apps require the human to approve the payment. The source repo is available on request for customisation. ## For agents - MCP endpoint: https://damngoodsales.com/mcp - Auth: OAuth 2.1 with dynamic client registration and PKCE - Store tools: whoami, search_catalog, get_product, acquire, check_acquisition, my_packages, request_repo - First app ($29 USD one-time): Damngood CRM Lite (tools: crm_list_leads, crm_get_lead, crm_create_lead, crm_import_leads, crm_update_lead, crm_move_lead, crm_add_note, crm_set_next_step, crm_due_followups, crm_pipeline_summary, crm_export_leads, crm_delete_lead; resource dgs://apps/crm-lite/guide; prompt crm_daily_review) - Library context: resource dgs://library (what the user owns) ## Pages - [Home](https://damngoodsales.com/): what Damngoodsales is and how agents acquire apps - [How it works](https://damngoodsales.com/how-it-works): connect, discover, acquire, use, customise - [Catalog](https://damngoodsales.com/catalog): the library of apps for agents - [Damngood CRM Lite](https://damngoodsales.com/catalog/crm-lite): the first app: 12 management tools, an agent guide, data and license - [Agent access](https://damngoodsales.com/agent-access): MCP setup, OAuth flow, full tool reference, security - [FAQ](https://damngoodsales.com/faq): buying, approvals, connections, data and source code
