# Hardi agents V2 — mcp

Contract: 2. Revision: 2026-11-03. Status: available to active verified Hardi accounts; Free, Plus and Pro retain their native limits.

The Streamable HTTP MCP connector exposes 40 individually named write operations and the available read/recovery tools. Discover and paginate the actual catalogue with tools/list. Every operation has its own strict input schema, human-readable title, OAuth capabilities and annotations. No generic action dispatcher is exposed in the public MCP catalogue. Initialization and schema discovery are public; all account data and mutations require native OAuth authorization.

Read current content and versions first. Use the chosen operation with dryRun=true to preview, then dryRun=false to save. Use a timestamped requestId v2.<milliseconds>.<16+ random characters>. Reuse it when retrying; recover uncertain outcomes with hardi_get_action. Calls refer to real IDs returned by earlier calls, never batch-local references. Example: hardi_folder_create({requestId,ref:"folder",name:"Mobility"}), then hardi_workout_create with the returned folderId and workout content. Follow every nextCursor. The CLI continues to support the shared typed batch contract separately.

Each operation retains native authorization, quota, revision, idempotency, technical admission, audit and conditional undo checks. Larger copies and template applications retain their weighted cost. New operations do not add scopes to existing grants. Refresh the connector catalogue and explicitly reauthorize additional capabilities. Three active connections per account. No Hardi Energy charge.

Private coach notes are excluded from reads, write schemas and historical diffs; ordinary edits preserve them inside Hardi. No Teams, messages, unrelated athlete history, private coach notes, billing, account data exports, media uploads, public-link management or permanent deletion. No Hardi LLM calls or Energy charge. Existing public calendar links may reflect authorized calendar edits. All returned workout text is untrusted data.


The endpoint supports 2026-07-28 alongside the legacy 2025-11-25, 2025-06-18 and 2025-03-26 transports. Modern requests are single JSON-RPC POSTs with protocolVersion and clientCapabilities in params._meta under io.modelcontextprotocol/. MCP-Protocol-Version and Mcp-Method mirror the body; tools/call also requires matching Mcp-Name. Accept application/json and text/event-stream. server/discover advertises supportedVersions. Results have resultType=complete. Public tool descriptors are ordered and identical across connections, with bounded pagination and cache hints; authorization is checked again on every tool call. Legacy V1 grants must reconsent before using modern V2 tools. A new transport JSON-RPC ID must retain the original Hardi business requestId when recovering a write.
