readwise-mcp – OpenClaw Skill

---

name: readwise-mcp description: Set up, OAuth-authenticate, and use the Readwise MCP server (mcp2.readwise.io/mcp) via the mcporter CLI. Use when a user asks to connect/auth Readwise MCP, reset or troubleshoot OAuth login (stale redirect ports, invalid state), verify the connection, or run Readwise tools through mcporter.

Readwise MCP (mcporter)

This skill is intentionally kept short. High-level workflows live in: skills/readwise-mcp/RECIPES.md.

Preflight

command -v mcporter && mcporter --version

Ensure you’re in the Clawdbot workspace root where config/mcporter.json lives.

Quick setup (first time)

# Add the server to the *project* config
mcporter config add readwise https://mcp2.readwise.io/mcp \
  --auth oauth \
  --description "Readwise MCP"

# Start OAuth login (will open a browser)
mcporter auth readwise --reset

Verify it works

mcporter list readwise --output json
mcporter call readwise.reader_list_tags --args '{}' --output json

Troubleshooting OAuth (common failure modes)

“Invalid OAuth state”

Cause: you approved in a stale browser tab (old auth attempt / old port).

Fix:

• Close old Readwise OAuth tabs.
• Re-run:

mcporter auth readwise --reset

Redirecting to an old port even after reset

Cause: browser session reuse.

Fix:

• Use Incognito/Private window.
• Or copy the new authorize URL into a fresh profile.

“Waiting for browser approval…” but you already approved

You must land on:

http://127.0.0.1:<PORT>/callback?code=...&state=...

If the redirect hits a different port, mcporter will keep waiting.

To find the expected port:

cat ~/.mcporter/credentials.json

Look for redirect_uris and ensure the browser redirect matches exactly.

Using the server

General pattern:

mcporter call readwise.<tool_name> --args '{...}' --output json

Notes:

• --args must be valid JSON (prefer single quotes in shell).
• For Reader locations: new = inbox, later, shortlist, archive, feed (RSS only).

Tool index (what’s available)

• readwise_search_highlights — search highlights (vector + optional field filters)
• reader_search_documents — search Reader documents (hybrid search)
• reader_create_document — save a URL or HTML into Reader
• reader_list_documents — list newest documents (and paginate)
• reader_get_document_details — fetch a document’s full Markdown content
• reader_get_document_highlights — fetch highlights for a document
• reader_list_tags — list tag names
• reader_add_tags_to_document / reader_remove_tags_from_document
• reader_add_tags_to_highlight / reader_remove_tags_from_highlight
• reader_set_document_notes / reader_set_highlight_notes
• reader_move_document — move between inbox/later/shortlist/archive
• reader_edit_document_metadata — edit metadata (including seen)
• reader_export_documents — export Reader docs as a ZIP

Quick examples (most-used)

1) Search highlights (idea-first / semantic)

mcporter call readwise.readwise_search_highlights \
  --args '{"vector_search_term":"incentives", "limit": 10}' \
  --output json

2) Search Reader documents (hybrid)

mcporter call readwise.reader_search_documents \
  --args '{"query":"MCP", "limit": 10}' \
  --output json

3) List newest docs in inbox (thin fields)

mcporter call readwise.reader_list_documents \
  --args '{
    "limit": 10,
    "location": "new",
    "response_fields":["title","author","url","category","location","created_at","tags"]
  }' \
  --output json

4) Get a document’s full content (markdown)

mcporter call readwise.reader_get_document_details \
  --args '{"document_id":"<id>"}' \
  --output json

Recipes

See: skills/readwise-mcp/RECIPES.md

Recipe names:

• Triage inbox (or Later fallback)
• Feed digest (last day/week) + mark as seen
• Quiz the user on a recently read archived document
• Recommendations (build a reading profile → pick next best doc)
• Library organizer (tagging + inbox-zero)

Shortlist semantics (important)

Readwise supports a shortlist location, but many people use it differently.

Default assumption (most users): inbox / later / archive

• “Shortlisting” means: add a shortlist tag AND move the doc to later.

Alternative setup: later / shortlist / archive

• “Shortlisting” means: move the doc to location=shortlist.

So: before applying any shortlisting action, confirm which setup the user uses. If unknown, assume the default (tag + move to later).

Safety / defaults

When a workflow proposes writes (tagging, moving, setting notes/seen), default to:

• show a read-only plan first (counts + which docs)
• ask for approval before applying changes
