Add a list of todo items as individual blocks to today's daily page in Roam. Each item becomes its own actionable block with todo status. NOTE on Roam-flavored markdown: For direct linking: use [[link]] syntax. For aliased linking, use alias syntax. Do not concatenate words in links/hashtags - correct: #[[multiple words]] #self-esteem (for typically hyphenated words). IMPORTANT: Before using this tool, ensure that you have loaded into context the 'Roam Markdown Cheatsheet' resource.

Fetch page by title. Returns content in the specified format.

Create a new standalone page in Roam with optional content, including structured outlines and tables, using explicit nesting levels and headings (H1-H3). This is the preferred method for creating a new page with an outline in a single step. Best for:

• Creating foundational concept pages that other pages will link to/from

• Establishing new topic areas that need their own namespace

• Setting up reference materials or documentation

• Making permanent collections of information

• Creating pages with mixed text and table content in one call. Efficiency Tip: This tool batches page and content creation efficiently. For adding content to existing pages, use roam_process_batch_actions instead. IMPORTANT: Before using this tool, ensure that you have loaded into context the 'Roam Markdown Cheatsheet' resource.

Add a structured outline to an existing page or block (by title text or uid), with customizable nesting levels. To create a new page with an outline, use the roam_create_page tool instead. The outline parameter defines new blocks to be created. To nest content under an existing block, provide its UID or exact text in block_text_uid, and ensure the outline array contains only the child blocks with levels relative to that parent. Including the parent block's text in the outline array will create a duplicate block. Best for:

• Adding supplementary structured content to existing pages

• Creating temporary or working outlines (meeting notes, brainstorms)

• Organizing thoughts or research under a specific topic

• Breaking down subtopics or components of a larger concept Best for simpler, contiguous hierarchical content. For complex nesting (e.g., tables) or granular control over block placement, consider roam_process_batch_actions instead. API Usage Note: This tool performs verification queries after creation. For large outlines (10+ items) or when rate limits are a concern, consider using roam_process_batch_actions instead to minimize API calls. IMPORTANT: Before using this tool, ensure that you have loaded into context the 'Roam Markdown Cheatsheet' resource.

Import nested markdown content into Roam under a specific block. Can locate the parent block by UID (preferred) or by exact string match within a specific page. If a parent_string is provided and the block does not exist, it will be created. Returns a nested structure of the created blocks. API Usage Note: This tool fetches the full nested structure after import for verification. For large imports or when rate limits are a concern, consider using roam_process_batch_actions with pre-structured actions instead. IMPORTANT: Before using this tool, ensure that you have loaded into context the 'Roam Markdown Cheatsheet' resource.

Search for blocks containing a specific tag. Use primary_tag for the tag to find, and optionally page_title_uid to limit search to a specific page. Supports pagination via limit and offset. Use this tool to search for memories tagged with the ROAM_MEMORIES_TAG.

Search for blocks with a specific status (TODO/DONE) across all pages or within a specific page.

Search for block references within a page or across the entire graph. Can search for references to a specific block, a page title, or find all block references.

Search for parent or child blocks in the block hierarchy. Can search up or down the hierarchy from a given block.

Find pages that have been modified today (since midnight), with pagination and sorting options.

Search for blocks containing specific text across all pages or within a specific page. Use scope: "page_titles" to search for pages by namespace prefix (e.g., "Convention/" finds all pages starting with that prefix). This tool supports pagination via the limit and offset parameters.

Search for blocks or pages based on creation or modification dates. Not for daily pages with ordinal date titles.

Provides the comprehensive Roam syntax reference. Covers: formatting, links & references (page refs, block refs, embeds including embed-children and embed-path), tags, dates, tasks, attributes, queries (native and :q Datalog tables with built-in rules), tables, kanban, mermaid diagrams (with theme support), advanced components (dropdowns, tooltips, templates, document mode, word-count), CSS tags (#.rm-E, #.rm-hide, etc.), anti-patterns, tool selection guide, and API efficiency tips.

IMPORTANT: Always load this cheatsheet before creating or updating Roam content. It prevents common syntax errors and guides tool selection.

Add a memory or piece of information to remember, stored on the daily page with ROAM_MEMORIES_TAG tag and optional categories (unless include_memories_tag is false). NOTE on Roam-flavored markdown: For direct linking: use [[link]] syntax. For aliased linking, use alias syntax. Do not concatenate words in links/hashtags - correct: #[[multiple words]] #self-esteem (for typically hyphenated words). IMPORTANT: Before using this tool, ensure that you have loaded into context the 'Roam Markdown Cheatsheet' resource.

Retrieve all stored memories on page titled ROAM_MEMORIES_TAG, or tagged block content with the same name. Returns a combined, deduplicated list of memories. Optionally filter blocks with a specific tag and sort by creation date.

Execute a custom Datomic query on the Roam graph for advanced data retrieval beyond the available search tools. This provides direct access to Roam's query engine. Note: Roam graph is case-sensitive.

Optimal Use Cases for roam_datomic_query:

• Advanced Filtering (including Regex): Use for scenarios requiring complex filtering, including regex matching on results post-query, which Datalog does not natively support for all data types. It can fetch broader results for client-side post-processing.

• Highly Complex Boolean Logic: Ideal for intricate combinations of "AND", "OR", and "NOT" conditions across multiple terms or attributes.

• Arbitrary Sorting Criteria: The go-to for highly customized sorting needs beyond default options.

• Proximity Search: For advanced search capabilities involving proximity, which are difficult to implement efficiently with simpler tools.

List of some of Roam's data model Namespaces and Attributes: ancestor (descendants), attrs (lookup), block (children, heading, open, order, page, parents, props, refs, string, text-align, uid), children (view-type), create (email, time), descendant (ancestors), edit (email, seen-by, time), entity (attrs), log (id), node (title), page (uid, title), refs (text). Predicates (clojure.string/includes?, clojure.string/starts-with?, clojure.string/ends-with?, <, >, <=, >=, =, not=, !=). Aggregates (distinct, count, sum, max, min, avg, limit). Tips: Use :block/parents for all ancestor levels, :block/children for direct descendants only; combine clojure.string for complex matching, use distinct to deduplicate, leverage Pull patterns for hierarchies, handle case-sensitivity carefully, and chain ancestry rules for multi-level queries.

RATE LIMIT EFFICIENT: This is the most API-efficient tool for multiple block operations. Combine all create/update/delete operations into a single call whenever possible. For intensive page updates or revisions, prefer this tool over multiple sequential calls.

Executes a sequence of low-level block actions (create, update, move, delete) in a single, non-transactional batch. Actions are executed in the provided order.

UID Placeholders for Nested Blocks: Use {{uid:name}} syntax for parent-child references within the same batch. The server generates proper random UIDs and returns a uid_map showing placeholder→UID mappings. Example: { uid: "{{uid:parent1}}", string: "Parent" } then { location: { "parent-uid": "{{uid:parent1}}" }, string: "Child" }. Response includes { success: true, uid_map: { "parent1": "Xk7mN2pQ9" } }.

For actions on existing blocks, a valid block UID is required. Note: Roam-flavored markdown, including block embedding with ((UID)) syntax, is supported within the string property for create-block and update-block actions. For actions on existing blocks or within a specific page context, it is often necessary to first obtain valid page or block UIDs. Tools like roam_fetch_page_by_title or other search tools can be used to retrieve these UIDs before executing batch actions. For simpler, sequential outlines, roam_create_outline is often more suitable. IMPORTANT: Before using this tool, ensure that you have loaded into context the 'Roam Markdown Cheatsheet' resource.

Fetch a block by its UID with optional children (down to a specified depth) and/or ancestors (up to page root). Returns the block's UID, text, order, children array, and optionally an ancestors array with the chain to the page root.

Create a table in Roam with specified headers and rows. This tool abstracts the complex nested structure that Roam tables require, making it much easier to create properly formatted tables.

Why use this tool:

• Roam tables require precise nested block structures that are error-prone to create manually

• Automatically handles the {{[[table]]}} container and nested column structure

• Validates row/column consistency before execution

• Converts empty cells to spaces (required by Roam)

Example: A table with headers ["", "Column A", "Column B"] and rows [{label: "Row 1", cells: ["A1", "B1"]}] creates a 2x3 table. IMPORTANT: Before using this tool, ensure that you have loaded into context the 'Roam Markdown Cheatsheet' resource.

Move a block to a new location (different parent or position). This is a convenience wrapper around roam_process_batch_actions for single block moves.

Update an existing page with new markdown content using smart diff. Preserves block UIDs where possible and generates minimal changes. This is ideal for:

• Syncing external markdown files to Roam

• AI-assisted content updates that preserve references

• Batch content modifications without losing block references

How it works:

1. Fetches existing page blocks

2. Matches new content to existing blocks by text similarity

3. Generates minimal create/update/move/delete operations

4. Preserves UIDs for matched blocks (keeping references intact)

IMPORTANT: Before using this tool, ensure that you have loaded into context the 'Roam Markdown Cheatsheet' resource.

Fetch a complete page view that mirrors what Roam Research shows in its UI: the page's own content, plus all linked references (backlinks) grouped by source page, each with their ancestor breadcrumb context and children expanded to the specified depth. Use this when you need the full picture of a page — both what is written on it and everything else in the graph that references it.

Fetch all sub-pages (namespace children) of a given page prefix. Matches by page title prefix — pages titled "Prefix/Something" are sub-pages of "Prefix" and appear in the Hierarchy section of that page. This is namespace/title-prefix matching, distinct from roam_search_hierarchy which traverses block parent/child relationships. Optionally filter to only sub-pages containing a specific tag (e.g. filter active projects with filter_tag="active"), and optionally include each sub-page's full block content.

Rename a page by changing its title. Identifies the page by current title or UID.
