How to use the Readwise MCP tools — access highlights, documents, and your entire reading library via MCP
What this skill does
# Readwise MCP
Use the Readwise MCP tools to access the user's Readwise highlights and Reader documents. Readwise has two products:
- **Readwise** — highlights from books, articles, podcasts, and more. Includes daily review and spaced repetition.
- **Reader** — a read-later app for saving and reading articles, PDFs, EPUBs, RSS feeds, emails, tweets, and videos.
## Setup
Add the Readwise MCP server to your client's configuration:
```json
{
"readwise": {
"type": "http",
"url": "https://mcp2.readwise.io/mcp"
}
}
```
The server handles authentication via OAuth — the user will be prompted to authorize on first use.
## Tool Reference
All tools are prefixed with `mcp__readwise__`. Each tool name maps directly to a Readwise or Reader API action.
## Reader Tools
### Searching documents
```
reader_search_documents(query="spaced repetition")
```
Hybrid search (semantic + keyword) across all saved documents. Combine with filters to narrow results:
```
# Search articles saved for later
reader_search_documents(query="machine learning", category_in=["article"], location_in=["later", "shortlist"])
# Search by author
reader_search_documents(query="AI agents", author_search="Simon Willison")
# Search within a date range
reader_search_documents(query="transformers", published_date_gt="2024-01-01")
# Search by tags
reader_search_documents(query="productivity", tags_in=["research"])
```
Other filters: `title_search`, `summary_search`, `note_search`, `url_search`, `source_search`, `document_id`, `limit` (default 20, max 100).
### Browsing documents
```
# List 10 most recent inbox items with minimal fields
reader_list_documents(location="new", limit=10, response_fields=["title", "author", "summary", "word_count", "category", "saved_at"])
# Archived articles with a specific tag
reader_list_documents(location="archive", tag=["research"], category="article")
# Unseen inbox items
reader_list_documents(location="new", seen=false)
# RSS feed items
reader_list_documents(location="feed", limit=20, response_fields=["title", "author", "summary", "site_name"])
# Get a specific document by ID
reader_list_documents(id="<document_id>")
# Paginate through results
reader_list_documents(location="later", limit=10, page_cursor="<cursor_from_previous_response>")
```
Locations: `new` (inbox), `later`, `shortlist`, `archive`, `feed`. When the user says "inbox", use `new`. Only use `feed` when the user explicitly asks about RSS/feeds.
Use `response_fields` to limit returned data and save tokens. The `id` field is always included. Available fields: `url`, `title`, `author`, `source`, `category`, `location`, `tags`, `site_name`, `word_count`, `reading_time`, `created_at`, `updated_at`, `published_date`, `summary`, `image_url`, `content`, `source_url`, `notes`, `parent_id`, `reading_progress`, `first_opened_at`, `last_opened_at`, `saved_at`, `last_moved_at`, `html_content`, `is_deleted`.
Tip: unseen documents have `first_opened_at=null`. Mark as seen via `reader_bulk_edit_document_metadata`.
### Reading and highlighting
```
# Get full document details including Markdown content
reader_get_document_details(document_id="<id>")
# Get all highlights on a document
reader_get_document_highlights(document_id="<id>")
# Create a highlight — html_content must match the document's HTML exactly
# Get the HTML via reader_list_documents with response_fields=["html_content"]
reader_create_highlight(document_id="<id>", html_content="<p>The exact passage to highlight</p>")
# Highlight with a note and tags
reader_create_highlight(document_id="<id>", html_content="<p>Key insight</p>", note="Connects to spaced repetition", tags=["review", "concept"])
```
### Saving documents
```
# Save a URL — Reader scrapes it automatically
reader_create_document(url="https://example.com/article")
# Save with metadata and tags
reader_create_document(url="https://example.com", title="Great Article", tags=["research", "ai"], notes="Recommended by Alice")
# Save raw Markdown content (provide a unique URL as identifier)
reader_create_document(title="Meeting Notes", markdown="# Notes from today...", url="https://me.com#notes-march-2025")
```
### Organizing
```
# Move documents between locations (max 50 per call)
reader_move_documents(document_ids=["<id1>", "<id2>"], location="archive")
# Bulk mark documents as seen
reader_bulk_edit_document_metadata(documents=[{"document_id": "<id>", "seen": true}])
# Bulk update metadata
reader_bulk_edit_document_metadata(documents=[{"document_id": "<id>", "title": "Better Title", "tags": ["ai", "research"]}])
```
Note: `reader_move_documents` and `reader_bulk_edit_document_metadata` share a rate limit of 20 calls/minute. Batch document IDs into fewer calls.
### Tags
```
# List all tags
reader_list_tags()
# Add tags to a document
reader_add_tags_to_document(document_id="<id>", tag_names=["important", "research"])
# Remove tags from a document
reader_remove_tags_from_document(document_id="<id>", tag_names=["old-tag"])
# Add tags to a highlight
reader_add_tags_to_highlight(document_id="<id>", highlight_document_id="<hid>", tag_names=["concept"])
# Remove tags from a highlight
reader_remove_tags_from_highlight(document_id="<id>", highlight_document_id="<hid>", tag_names=["old-tag"])
# Set notes on a highlight (pass null to clear)
reader_set_highlight_notes(document_id="<id>", highlight_document_id="<hid>", notes="My updated note")
```
### Exporting
```
# Export all documents as a ZIP of Markdown files (async — returns export_id)
reader_export_documents()
# Delta export — only docs updated since last export
reader_export_documents(since_updated="2024-01-01T00:00:00Z")
# Poll for completion
reader_get_export_documents_status(export_id="<id>")
```
Poll `reader_get_export_documents_status` until `status` is `"completed"`, then use the `download_url`.
## Readwise Tools
### Searching highlights
```
# Semantic search across all highlights
readwise_search_highlights(vector_search_term="learning techniques")
# Search with full-text filter on a specific field
readwise_search_highlights(vector_search_term="memory", full_text_queries=[{"field_name": "document_title", "search_term": "psychology"}])
```
Full-text query fields: `document_author`, `document_title`, `highlight_note`, `highlight_plaintext`, `highlight_tags`.
### Browsing highlights
```
# List 20 most recent highlights
readwise_list_highlights(page_size=20)
# Highlights from a specific book
readwise_list_highlights(book_id=12345)
# Highlights from the last month
readwise_list_highlights(highlighted_at_gt="2025-02-01T00:00:00Z")
# Paginate
readwise_list_highlights(page_size=100, page=2)
```
### Creating and editing highlights
```
# Create a highlight (matched to a book by title/author, or goes into "Quotes")
readwise_create_highlights(highlights=[{"text": "The key insight here", "title": "Book Title", "author": "Author Name"}])
# Create multiple highlights at once
readwise_create_highlights(highlights=[{"text": "First quote", "title": "Book A"}, {"text": "Second quote", "title": "Book B", "note": "Great point"}])
# Update a highlight
readwise_update_highlight(highlight_id=12345, note="New note", add_tags=["concept", "review"], color="blue")
# Delete a highlight
readwise_delete_highlight(highlight_id=12345)
```
Colors: `yellow`, `blue`, `pink`, `orange`, `green`, `purple`.
### Daily review
```
# Get today's spaced repetition review
readwise_get_daily_review()
```
Returns highlights selected by the algorithm plus a URL for interactive review.
## Example Workflows
**Triage the inbox:** List recent saves, read each one, decide what's worth the user's time.
```
reader_list_documents(location="new", limit=10, response_fields=["title", "author", "summary", "word_count", "category", "saved_at"])
reader_get_document_details(document_id="<id>")
reader_move_documents(document_ids=["<id>"], location="later") # worth reading
reader_move_documents(document_ids=["<id>"], location="aRelated in AI Agents
skill-development
IncludedComprehensive meta-skill for creating, managing, validating, auditing, and distributing Claude Code skills and slash commands (unified in v2.1.3+). Provides skill templates, creation workflows, validation patterns, audit checklists, naming conventions, YAML frontmatter guidance, progressive disclosure examples, and best practices lookup. Use when creating new skills, validating existing skills, auditing skill quality, understanding skill architecture, needing skill templates, learning about YAML frontmatter requirements, progressive disclosure patterns, tool restrictions (allowed-tools), skill composition, skill naming conventions, troubleshooting skill activation issues, creating custom slash commands, configuring command frontmatter, using command arguments ($ARGUMENTS, $1, $2), bash execution in commands, file references in commands, command namespacing, plugin commands, MCP slash commands, Skill tool configuration, or deciding between skills vs slash commands. Delegates to docs-management skill for official documentation.
reprompter
IncludedTransform messy prompts into well-structured, effective prompts — single or multi-agent. Use when: "reprompt", "reprompt this", "clean up this prompt", "structure my prompt", rough text needing XML tags and best practices, "reprompter teams", "repromptception", "run with quality", "smart run", "smart agents", multi-agent tasks, audits, parallel work, anything going to agent teams. Don't use when: simple Q&A, pure chat, immediate execution-only tasks. See "Don't Use When" section for details. Outputs: Structured XML/Markdown prompt, quality score (before/after), optional team brief + per-agent sub-prompts, agent team output files. Success criteria: Single mode quality score ≥ 7/10; Repromptception per-agent prompt quality score 8+/10; all required sections present, actionable and specific.
adaptive-compaction
IncludedAdaptive add-on policy and recovery layer that decides WHEN to compact, prune, snapshot, or fork -- replacing fixed-percent auto-compaction across Claude Code, Codex, and MCP-capable hosts. Trigger on auto-compact timing or damage: "when should I compact", "is it safe to compact now or start a fresh session", "auto-compact fires too early/mid-task", "switching to an unrelated task but the window still has space", "context rot", "answers get worse the longer the session runs", "the agent forgot the plan or my decisions after it summarized", "add a layer on top that manages context without changing the agent", raising autoCompactWindow to give the policy room, or installing/tuning a cross-tool compaction policy or PreCompact hook -- even when "compaction" is never said but the problem is context-window pressure or post-summarization memory loss. Do NOT use to summarize a conversation, build RAG, write a summarization prompt (decides WHEN not HOW), or answer max-context-length trivia.
agent-skill-creator
IncludedCreate cross-platform agent skills from workflow descriptions. Activates when users ask to create an agent, automate a repetitive workflow, create a custom skill, or need advanced agent creation. Triggers on phrases like create agent for, automate workflow, create skill for, every day I have to, daily I need to, turn process into agent, need to automate, create a cross-platform skill, validate this skill, export this skill, migrate this skill. Supports single skills, multi-agent suites, transcript processing, template-based creation, interactive configuration, cross-platform export, and spec validation.
llm-wiki
IncludedUse when building or maintaining a persistent personal knowledge base (second brain) in Obsidian where an LLM incrementally ingests sources, updates entity/concept pages, maintains cross-references, and keeps a synthesis current. Triggers include "second brain", "Obsidian wiki", "personal knowledge management", "ingest this paper/article/book", "build a research wiki", "compound knowledge", "Memex", or whenever the user wants knowledge to accumulate across sessions instead of being re-derived by RAG on every query.
skill-master
IncludedAgent Skills authoring, evaluation, and optimization. Create, edit, validate, benchmark, and improve skills following the agentskills.io specification. Use when designing SKILL.md files, structuring skill folders (references, scripts, assets), ingesting external documentation into skills, running trigger evals, benchmarking skill quality, optimizing descriptions, or performing blind A/B comparisons. Keywords: agentskills.io, SKILL.md, skill authoring, eval, benchmark, trigger optimization.
