# Coral

> Coral is the trusted execution layer for AI agents: one MCP server for every service they use, with your credentials and your rules. Agents act across more of your systems with precise controls.

Coral is open source (Apache 2.0) and local-first: credentials, data and run history stay on your machine or your own servers.

## Key capabilities

- Any OpenAPI document or MCP server becomes a provider
- Agents write short TypeScript programs that call providers; Coral runs each program in a sandbox, adds the credentials, and checks every call against your policy
- Per-operation policy: allow, require approval, or disable
- Workspaces: connect providers to groups of employees and agents, each with its own rules
- Approvals: people approve gated actions in the agent's own UI (such as Claude or Codex), and every approval is logged in Coral
- Saved workflows: agents reuse programs that already work instead of writing them again, and every agent can use and add to the shared library
- Smaller context: agents search for the operations they need instead of loading them all up front
- Every run is recorded, so you can review each program and the calls it made
- Agents connect to one MCP server over HTTP

## Models

Coral Sailfish is a family of open-weights models post-trained on Coral trace and workflow data for enterprise tool calls. On 34 enterprise tool-call tasks, Sailfish 1 beat an equivalent-size model, Qwen 3.6 35B A3B, by +300% accuracy and +15% speed (speed depends on the self-hosting architecture), at 75% lower cost (at high scale and utilization).

## Benchmarks

Opus quality at Haiku pricing: in blind benchmarks of 100 enterprise tasks (run 15 October 2026 with the same agents and data sources: GitHub, Slack, Linear, Notion), Claude Haiku 5.5 with Coral matched the accuracy of Claude Opus 5.5 with direct MCPs (99%) at about 2% of the average token cost per task ($0.006 vs $0.28).

- Claude Opus 5.5 with Coral: 100% accuracy at $0.24 per task, vs 99% at $0.28 with direct MCPs
- Against MCP gateways, Claude Opus 5.5 with Coral reached 100% accuracy at $0.25 per task; with Microsoft's gateway it reached 98% at $0.32, with Kong 98.9% at $0.34 and with Composio 98% at $0.40
