Full-text search across the user's MindBase wiki — matches page titles, one-liners, and slugs. Returns ranked list with snippets.

Search the user's wiki across EVERY project (not just the current one). Returns ranked matches with their owning project id, suitable for citing as [[<project>/<slug>]] cross-project wikilinks. Use this when answering open-ended "have I seen this before" questions or proposing cross-project bridges during ingest.

Read the full content (markdown body + frontmatter + incoming/outgoing wikilinks) of a wiki page by its slug.

List wiki pages added or updated within the past N days, newest first.

Find pages connected to a given page via wikilinks, shared tags, or shared sources. Returns a ranked list with the connection reason.

Embedding-based semantic search across the wiki. Falls back to keyword search if embeddings are unavailable.

Search the wiki, restricted to pages tagged with a specific project (uses the project frontmatter field).

Ask a natural-language question against the user's wiki. Performs graph-aware retrieval (search → top hits + their 1-hop wikilinks) and returns a cited answer using the configured LLM. Best tool for "what do I know about X?" questions. The answer text contains [N] citation markers — match each N to the corresponding entry in the citations array and render as a clickable link to mindbase_uri.

Ingest a new source into the wiki: saves the raw text, runs LLM compile to create/update wiki pages, applies cross-linking. Returns a summary of changes.

Conversational ingest, step 1 of 2. Reads the source, returns the LLM's narrative takeaways and a structured plan of proposed actions — without writing anything yet. The user reviews the takeaways + plan, decides which actions to approve, and then calls ingest_execute(planId, approvals) to commit the approved subset.

Conversational ingest, step 2 of 2. Commits the user-approved subset of a plan returned by ingest_plan. approvals is a map of action id → boolean; omitted ids default to approved (true). Returns the per-action results plus a summary of what got created / updated.

Save content to the inbox for later batch processing (NOT a direct wiki note). Use this for "save this for later, I will categorize it myself in the MindBase UI". To create a wiki note directly, use create_note instead.

Save a fragment of the current AI conversation as a wiki page. LLM auto-titles it if no suggested_title. Marks created_via: mcp for audit.

Append content to a section of an existing wiki page. Creates the section if missing. Refuses to modify human-edited pages unless force: true.

Replace the content under a section heading on an existing page. Refuses to modify human-edited pages unless force: true.

Add or replace tags on a wiki page. mode: "add" merges with existing tags (default); "replace" overwrites.

Set the visibility level of a wiki page. "internal" and "pii" pages are excluded from semantic search and Q&A by default.

List recent chat sessions saved in MindBase, newest first.

Search past saved chat conversations by content. Returns matching chats with previews.

Compute graph insights for the wiki: top hubs, orphans, broken links, fragmented tag clusters.

List wiki pages with no incoming links (orphans).

Suggest wikilinks that should be added to a specific page (review mode — does NOT modify the page).

Run the full Wiki Health pipeline: build graph → generate insights → auto cross-link → L2 lint. Writes _insights.md and applies improvements.

Export a page + its connected neighbors (up to N hops) as a self-contained markdown bundle.

Generate a morning brief summarizing recent wiki activity with [N] citations. Default 24h lookback. Does not email — for that use the web UI Settings → Daily Brief → Send Now.

Subscribe MindBase to a new RSS feed. New entries are auto-fetched every 60 minutes and compiled into wiki pages. Use this when the user says things like "subscribe me to ", "follow this blog", "add this to my feeds", or shares a feed URL.

List all RSS feeds the user is subscribed to, with stats (last poll time, items ingested, errors). Use this when the user asks "what feeds am I subscribed to?" or wants to check their RSS subscriptions.

List spaced-repetition review cards. By default returns cards due now (due_only=true). Use this to conduct an interactive review session: list due cards, present each Q to the user, wait for their answer, call answer_card, repeat.

Submit an answer to a review card. Use ratings as: forgot (didn't know), hard (struggled), good (right answer with effort), easy (instant recall). After answering, the card is rescheduled according to SM-2.

Create a new review card manually. Use this when you and the user have just discussed a fact worth remembering long-term, e.g. "add this to my reviews". The card will be scheduled for review immediately.

Create a new wiki note. Use for: capturing a thought, starting a research page, or building a meeting/person/project page from a template. At least one of title or content is recommended. If template is given, it is filled with standard vars (date, time, slug, yesterday_slug, tomorrow_slug, title) plus any custom variables. Existing slugs cause an error — use append_to_page or update_note_section to extend.

Open or create the daily note for today (or a specific date). Daily notes follow the slug pattern daily-YYYY-MM-DD and are auto-linked to yesterday/tomorrow. Returns the existing page if already created, marking created: false.

Overlay a schema template onto an existing project. Appends template prose to README.md and seeds template-specific sections in context.md. Idempotent — re-running with same template is a no-op marker.

Synthesize what the user's wiki collectively knows about a topic. Returns structured threads with row-level citations, contradictions, and gaps. Cached; pass force_refresh: true to regenerate.

Get today's (or a specific date's) wiki pulse: weekly writes, new connections, contradictions, stale notes, SRS due count. Use to give the user a daily situational awareness of their knowledge base.

Find self-contradictions in the wiki on a given topic. Returns only contradictions, no full synthesis. Useful when the user wants to reconcile evolving views.

Find gaps in the wiki's coverage of a topic. Returns LLM-suggested missing pieces (e.g., "you mention X but never document Y").

Scaffold a new MindBase project with the v2 layout: README.md, context.md, index.yaml, sources/contributors/, sources/research/, sources/raw/, state/, logs/, artifacts/. Idempotent — refuses to overwrite existing project.

Load the README + context + index.yaml for a project (defaults to currentProjectId in config.json). Returns the three file bodies for context injection. Read-only by default; pass persist=true to also update config.json currentProjectId (i.e. switch the active project).

Append a contributor entry to the current project. Writes to sources/contributors//.md (append-only) plus log entry. Route mode forces routing: auto (LLM decides), daily (only contributor file), concept (also flag for /mb:build to extract concept), daily+concept (both).

Validate that a project conforms to the v2 layout. Returns list of missing required files/dirs. Used as a precondition guard by /mb:build and /mb:migrate.

Append a structured entry to logs/.md. Format: ## [YYYY-MM-DD HH:MM] {operation} | {topic} | {details}

List contributor + research files modified since the last build (or since a given ISO date). Returns paths + sizes + mtimes. Used by /mb:build to know what to synthesize.

Write new content into context.md atomically. Steps: (1) snapshot current context.md → state/builder/snapshots/.md, (2) tmpwrite + rename, (3) append log entry. Enforces 400-line cap by truncating overflow to sources/research/.md.

Regenerate index.yaml by scanning the project tree. Always overwrites; never partial-merges. Output schema: { project, files, contributors, sources, last_build }.

Project dashboard: last build time, line counts, contributor stats, recent operations, file counts. Read-only.

Migrate one or all projects from legacy wiki/ layout to v2 layout. Snapshots to archive/-/ first; idempotent on re-run.

Ingest a file (PDF, .md, or .txt) into a project: archives the original into sources/raw//, extracts text locally (pdfjs for PDFs — no API call), writes an .extracted.md sidecar for PDFs, and returns the text. Accepts a local absolute path OR an http(s) URL that points directly at a file (e.g. an arXiv PDF link) — URLs are downloaded first. After calling this, discuss the key takeaways with the user and file a summary via mindbase_contribute.

Save research findings to sources/research/.md. Appends if file exists; otherwise creates. Always appends a log entry.

Export a project to a portable artifact. markdown-bundle: copies project tree to artifacts/exports/-/. zip-archive: same plus zips (uses zip if available).
