These examples configure a project-local STDIO server; they do not modify global client configuration. Agent 5 must pin the official Python MCP SDK at mcp==2.0.0 and provide python -m reglineage mcp using that SDK at the transport/schema boundary. The shared composition must inject the durable capability runtime, registered replay/tools, monitoring/ContextPatch services, separate approval store, and strict DataHub publisher/readback.
The server writes only newline-delimited JSON-RPC to stdout. Its client attribution is not authenticated identity. Until the commands below are exercised with the named clients, label the evidence CLIENT_NEUTRAL_STDIO_PROTOCOL_TEST.
Copy the mcpServers.reglineage entry from claude-code.json into the repository's reviewed project-scoped Claude configuration. Do not add it globally on a user's behalf.
Copy codex-config.toml into the repository's reviewed project configuration or merge its mcp_servers.reglineage table. Do not alter a user's global configuration.
Both clients must discover the same tool schemas, DataHub URNs, decision hashes, and durable state. Neither client may grant an approval or submit SQL.
