@tesseron/core

Protocol types and action builder for Tesseron.

Transport-agnostic, validator-agnostic. Defines the JSON-RPC 2.0 wire protocol (version 1.0.0) between the SDK and the MCP gateway, the action/resource builder API, the handler context (ctx.confirm, ctx.elicit, ctx.sample, ctx.progress, ctx.log), subscribable resources, and the typed error hierarchy (SamplingNotAvailableError, ElicitationNotAvailableError, TimeoutError, CancelledError, TesseronError).

Zero runtime dependencies beyond @standard-schema/spec (types-only).
