Gap-fill: HTTP/SSE transport was not documented in the public docs.

Changes:

  • New "Transport modes" section explaining stdio (Claude Code/Cursor) vs HTTP/SSE (remote agents)
  • SSE heartbeat behaviour documented (data: null every 30s on idle)
  • MCP_SERVER_PORT and MOLECULE_API_KEY added to env vars table
  • Troubleshooting entry added for port-in-use

Gap-fill: the MCP server supports HTTP/SSE transport (controlled by
MCP_SERVER_PORT) but this was only mentioned in the server's internal
README, not in the public docs. This adds a "Transport modes" section
explaining stdio (default, for Claude Code/Cursor) and HTTP/SSE (for
remote agents and headless clients), including the SSE heartbeat
behaviour.

Also adds MOLECULE_API_KEY and MCP_SERVER_PORT to the env vars table
(gap identified in PR #42), and a troubleshooting entry for port-in-use.

[technical-writer-agent] Tech writer review — APPROVED.

Gap-fill: the MCP server supports HTTP/SSE transport (for remote agents and headless clients) but this was undocumented in the public docs site. The new Transport modes section explains the distinction between stdio (local AI clients) and HTTP/SSE (remote agents), documents the SSE heartbeat behaviour (data: null every 30s on idle), and covers how to start the server in HTTP/SSE mode. Also consolidates MCP_SERVER_PORT and MOLECULE_API_KEY into the env vars table.

LGTM — HTTP/SSE transport mode docs cover stdio vs HTTP/SSE distinction, SSE heartbeat behaviour, env vars table, and troubleshooting. Well-structured gap-fill.

[technical-writer-agent] Quality review: HTTP/SSE transport section is accurate and well-structured. Correct stdio vs HTTP/SSE distinction, SSE heartbeat documented (data: null every 30s), env vars table additions are correct. APPROVE. Note: small overlap with #42 on env vars table additions — merge #42 before #43 for clean sequencing.

PR Review: MCP HTTP/SSE transport docs (PR #43)

Scope: 29-line addition to content/docs/mcp-server.mdx.

Correctness

  • Transport modes section correctly distinguishes stdio (local clients like Claude Code/Cursor) from HTTP/SSE (remote/headless agents).
  • SSE heartbeat behaviour (data: null every 30s on idle) documented — critical for users behind proxies that close idle connections.
  • MCP_SERVER_PORT and MOLECULE_API_KEY added to the env vars table — fills a documented gap.
  • Troubleshooting entry for "Port already in use" with MCP_SERVER_PORT fix.

Completeness

  • Package version pinning (@1.0.0) with Callout warning matches the SEC-001 guidance from the G-01 audit (KI-001 / G-01 in known-issues.md).
  • Quick start example uses exact pin

Minor suggestion (non-blocking)

  • The MCP_SERVER_PORT default value in the env table could note "defaults to 3000" to match the description column format.
  • The HTTP/SSE agent card URL http://localhost:3000/agent/card assumes default port — worth noting in the prose that the port must match MCP_SERVER_PORT.

Recommendation: Approve. Clean gap-fill, accurate, well-structured.
