Md Log Mcp

Review the report, not the diff. An MCP server that lets your AI coding agent — Claude Code, Claude Desktop, Codex, Cursor — save its work and analysis as immutable, versioned Markdown reports into md-log, a human-in-the-loop review & archive layer for "vibe coding." You then read and stylus-annotate (S-Pen / Apple Pencil) those reports on web, phone, and tablet — every save a new immutable version.

A Model Context Protocol server — two transports, one tool set — that lets Claude Code (and other agents) save .md files — text and embedded screenshots together — straight into md-log, a human-in-the-loop review & archive layer for vibe coding. The recommended way to connect is the hosted remote endpoint (https://mcp.md-log.com/mcp, a URL + your key — no install); a local stdio (npx -y md-log-mcp) transport is the alternative. The agent writes a report by path (my-project/2026-07-07-error-report.md); missing folders are auto-created, images are uploaded and their references rewritten to asset:// links, and every save becomes an immutable new version. The same report is then readable, editable, and stylus-annotatable (S-Pen / Apple Pencil where supported) on a phone or tablet, and on the web.

md-log is a hosted service at https://app.md-log.com — you don't run any server yourself. This package is just the connector: a thin authenticated HTTP client that validates POSIX paths, orchestrates asset uploads, maps errors to stable agent codes, and forwards everything to the hosted md-log service — the single authority for auth, storage, versioning and quota. All you need is a Personal Access Token from the web app.

Stack

• @modelcontextprotocol/sdk (TypeScript) — one McpServer (17 tools), two transports.
• stdio transport (md-log-mcp) — JSON-RPC over stdin/stdout; the default local mode (so stdout is reserved for the protocol; logs go to stderr). PAT from env.
• Streamable HTTP transport (md-log-mcp-http) — the remote mode: agents connect by URL with no local install; the PAT is taken per request from the Authorization header. See Remote (Streamable HTTP) mode.
• TypeScript, bundled with tsup to ESM dist/server.js (stdio) + dist/http.js (HTTP). Runtime deps: the MCP SDK and zod (input schemas). Node's built-in fetch/http are the only network layers — no web framework.
• PAT auth — a md-log Personal Access Token sent to the backend as Authorization: Bearer.

Requirements

• Node 22+
• A Personal Access Token (PAT) minted in the md-log web app (Settings → Tokens; shown once)

That's it — the md-log service itself is hosted at https://app.md-log.com; there is nothing to install or self-host.

Tools (17)

Every tool returns dual output — a human-readable content[].text and a machine-readable structuredContent — and validates the POSIX path (NFC-normalize; reject ../., control chars, empty/whitespace segments, backslashes, reserved names; enforce 255-byte name / 1024-byte path limits; require .md for files) before any backend call. All requests hit the base URL in MDLOG_API_BASE_URL (which already includes /api/v1).
