Luther Systems
Luther Systems is a London- and Campbell, CA-based enterprise software company (Luther Systems Limited and Luther Systems US Incorporated) whose Luther Platform automates end-to-end enterprise processes — "Deep Process Automation" — for customers such as Allianz and DLA Piper's TOKO, running business logic (ELPS "phyla") on the Substrate runtime over Hyperledger Fabric with ConnectorHub integrations, a shiroclient JSON-RPC gateway, LutherAuth identity and Buf-managed Protobuf contracts. Its public, agent-native surface is two products: AgentSearch (agentsearch.luthersystems.com) — a free, no-auth, daily-scored index of ~4,300 AI agents and MCP servers exposed as an OpenAPI 3.1 HTTP API, a hosted Streamable HTTP MCP server (5 tools) plus an npm stdio package, and an A2A 0.3.0 agent card with a live JSON-RPC endpoint — and InsideOut (Riley) — an agentic cloud architect that designs, prices, generates Terraform for, deploys and inspects AWS/GCP infrastructure through a hosted MCP server at app.luthersystems.com (24 tools, session-scoped, no keys for design), an A2A 0.3 card, provider-published Agent Skills, Claude Code / Kiro / Cursor plugins and a Docker image. The enterprise platform ships Go SDKs, the shirotester CLI (with a local MCP server), the mars infrastructure CLI and a public docs repository with dated release notes.
Luther Systems publishes 11 API contracts indexed on the APIs.io network, including Agent API, Browse API, Found Agent API, and 8 more. Tagged areas include Agents, Agent Discovery, MCP, A2A, and Agent-Native.
Luther Systems’ developer surface includes pricing, documentation, API reference, getting-started guide, support, engineering blog, changelog, and 36 more developer resources.
