Coral is an open-source SQL query layer built to help AI agents and developers retrieve data from many systems without custom integration work. The platform connects to APIs, databases, and file systems, then exposes each source as a readonly schema that can be queried like a table. Teams can use Coral to combine information from tools such as GitHub, GitLab, Slack, Linear, Datadog, Sentry, OpenTelemetry, ClickUp, Incident.io, Intercom, Stripe, and PagerDuty. This makes it possible to answer complex operational questions with joins across engineering, communication, observability, workflow, and payment data. Coral is designed to work with both the CLI and MCP, allowing agents such as Claude Code or Codex to access one shared runtime. The platform manages authentication, pagination, rate limits, schema discovery, and source-specific execution details behind the scenes. Its readonly design helps agents gather context without mutating upstream systems or creating unnecessary safety risks. Coral also improves over time by learning schema hints, relationships, recommended joins, and query patterns from real usage. Features such as query pushdown, caching, and efficient pagination help reduce unnecessary API calls and lower token-heavy agent workflows. Teams can use Coral for coding assistance, AI SRE workflows, security and compliance investigations, customer escalations, and internal operations support. Coral helps organizations turn fragmented data sources into a unified query environment that makes agents more accurate, cost-efficient, and production-ready.
