* fix(pdf-server): stub DOMMatrix/ImageData/Path2D for npx without @napi-rs/canvas
pdfjs-dist/legacy/build/pdf.mjs does `new DOMMatrix()` at module scope.
Its own polyfill loads @napi-rs/canvas (an optionalDependency), but npx
frequently misses the platform-native binary (npm/cli#4828), so the
server crashed on `npx @modelcontextprotocol/server-pdf --stdio`:
ReferenceError: DOMMatrix is not defined
at pdfjs-dist/legacy/build/pdf.mjs:17078
The server only uses pdfjs for text/metadata/form-field extraction —
never canvas rendering — so no-op stubs suffice and avoid shipping
~130MB of native binaries.
The polyfill is a separate ESM module kept --external in the bun bundle
so it executes before pdfjs's hoisted static import; inlined body code
would run too late.
Broken since 1.3.0 (#506). Thanks to Bryan Thompson for the analysis
and fix shape from the npm-to-mcpb pipeline.
* fix(pdf-server): MCPB bundle missing runtime deps + display_name with spaces
`mcpb pack` zips whatever is on disk; in this monorepo all runtime deps
are hoisted to root node_modules, so the published .mcpb shipped without
pdfjs-dist/ajv/express/etc. and crashed on import in Claude Desktop.
build-mcpb.mjs stages dist/ + manifest into a clean temp dir, runs a
non-workspace `npm install --omit=dev --omit=optional` (the new
DOMMatrix polyfill makes @napi-rs/canvas's ~130MB of native binaries
unnecessary), syncs manifest.version to package.json, then packs.
Result: 12.3MB / 38.8MB unpacked, full MCP handshake + tools/list pass.
Also rename display_name "PDF (By Anthropic)" → "pdf-viewer" — spaces
in display_name break MCP App UI rendering for MCPBs in Claude Desktop.
CI now smoke-tests the extracted bundle starts (`dist/index.js --stdio`
prints "Ready") so a deps-less bundle can't ship again.
* fix(pdf-server): list interact in MCPB manifest tools (was stale since #491)
* Add MCPB packaging and Claude Code plugin for pdf-server
Two distribution paths for the pdf-server:
1. **MCPB bundle** (Claude Desktop MCP Directory):
- manifest.json: v0.3 manifest with tools, compatibility, privacy
- .mcpbignore: excludes source/tests from bundle
- icon.png: 64x64 PDF document icon
2. **Claude Code plugin** (plugin/):
- .mcp.json: declares local stdio server via npx
- commands: /pdf-research:read, /pdf-research:summarize
- skills: pdf-reading skill for document navigation
- Tested end-to-end: MCP server connects, all tools available
The plugin uses a local stdio MCP server pattern — the first known
instance in a knowledge-work plugin (all existing plugins use remote
HTTP connectors).
