# Context4 > Context4 connects AI clients to authorized business services through MCP and a public HTTP API. Documentation describes the implemented contract; availability still depends on the tenant, connection and permissions. Never infer successful authorization or execution from these docs. ## Deployment addresses - Documentation: https://ctx4.me/docs.md - Agent index: https://ctx4.me/docs/agent-index.json - Console and connections: https://console.ctx4.me/integrations - MCP: https://ctx4.me/mcp - HTTP API: https://ctx4.me/v1 - Composio base URL: https://ctx4.me/compat/context4/v1 - OpenAPI: https://ctx4.me/docs/openapi.json - HTTP/MCP inventory: https://ctx4.me/docs/api-index.json - Composio routes: https://ctx4.me/docs/compat-routes.json - Connectors: https://ctx4.me/docs/connectors.json ## Start here - [Agent bootstrap](https://ctx4.me/docs/agent-setup.md): Read first for client detection, MCP and skill installation, provider consent and first read. - [Skills](https://ctx4.me/docs/skills-index.json): Versioned files, archives and installation guides. - [Documentation](https://ctx4.me/docs): Product guides and technical reference. - [Documentation in Markdown](https://ctx4.me/docs.md): Documentation overview with links to every chapter as Markdown. - [Machine-readable index](https://ctx4.me/docs/agent-index.json): Every public chapter, its Markdown URL and description. - [Full documentation](https://ctx4.me/llms-full.txt): All chapters in one plain-text response. - [OpenAPI](https://ctx4.me/docs/openapi.json): Public HTTP operations and schemas.
