  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.

    Public, no-auth HTTP API for AgentSearch, Luther Systems' daily-scored index of AI agents and MCP
    servers, at https://agentsearch.luthersystems.com. Six operations described by a provider-published
    OpenAPI 3.1.0 (POST /api/search, GET /api/agent/{name}, POST /api/found-agent, GET /api/browse,
    GET /api/stats, GET /.well-known/agent.json) that the spec itself says mirrors the
    @luthersystems/agentsearch MCP server; POST /api/submit-agent is documented on /api-docs but not in
    the spec. Read-only, best-effort ~60 requests/minute/IP, MIT-licensed surfaces on GitHub.

    Buf-managed Protocol Buffers published at github.com/luthersystems/protos (module
    buf.build/luthersystems/protos) that define API contracts and shared messages across the Luther
    Enterprise platform: the pdfserv.v1 PDFService gRPC service (rpc Generate), healthcheck.v1,
    common.v1 exceptions, a sensitive-field annotation, and 80 ConnectorHub connector configuration
    schemas (Salesforce, SAP S/4HANA, Stripe, Postgres, Kafka, DocuSign, Equifax, Anthropic Claude ...).
    The platform is customer-deployed (public cloud, private cloud or on-premise) and exposes business
    logic through the shiroclient JSON-RPC gateway and grpc-gateway-transcoded middleware, so no public
    base URL exists; the sandbox starter kit shows the pattern with a SandboxService and a generated
    Swagger 2.0. Complemented by Go SDKs, the shirotester CLI and the Substrate Agent Skill.
