# Pawrly documentation > Query APIs, files, MCP servers, and databases with SQL — one governed SQL surface for agents and data teams. This is the documentation index for LLMs. Every link points to the raw Markdown source of a page (the .md endpoints); their internal links also resolve to .md, so you can crawl the docs as Markdown. The human-readable docs live at https://pawrly.dev/docs. ## Start here - [Overview](https://pawrly.dev/docs/overview.md): What Pawrly is and how the pieces fit together. - [CLI](https://pawrly.dev/docs/cli.md): Every command: sql, schema, validate, serve, status, mcp-stdio. - [Configuration](https://pawrly.dev/docs/config.md): The pawrly.yaml schema — sources, secrets, caching, safety. ## Connect data - [Sources](https://pawrly.dev/docs/sources.md): Wire up APIs, files, databases, warehouses, lakehouses, and MCP servers. ## Model & serve - [Semantic layer](https://pawrly.dev/docs/semantic.md): Dimensions, measures, relationships, segments, RLS, and pre-aggregations. - [Materialized tables](https://pawrly.dev/docs/materialize.md): Pin a query, file, or URL as a self-backed table. ## For agents - [MCP server](https://pawrly.dev/docs/mcp.md): Run Pawrly as an MCP server and consume other MCP servers as sources. ## Operate - [Observability](https://pawrly.dev/docs/observability.md): Traces, metrics, and a queryable activity log. - [Architecture](https://pawrly.dev/docs/architecture.md): Engine internals and local vs daemon behavior. - [Console](https://pawrly.dev/docs/console.md): The web console for browsing sources and running queries. ## More - [Install guide](https://pawrly.dev/install.md): install + first query, copy-pasteable. - [Full machine-readable reference](https://pawrly.dev/llms-full.txt): overview, install, sources, features in one fetch. - [Site index](https://pawrly.dev/llms.txt): the whole site, not just docs. - [JSON Schema for pawrly.yaml](https://pawrly.dev/pawrly.schema.json): editor completion + validation.
