Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security50

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
add_topic Add Topic ~109
Add a research topic for paper search.
| Name | Type | Req | Description |
|---|---|---|---|
| key | string | yes | Short identifier (e.g. "llm-reasoning", "rag-retrieval"), lowercase with hyphens |
| keywords | array | yes | Search keywords for this topic (3-5 recommended) |
| label | string | yes | Human-readable name (e.g. "LLM Reasoning") |
| weight | number | – | Priority weight 0.0-1.0 (default 1.0 = highest priority) |
Structured output declared, but exposes no named fields.
No examples provided.
collect Collect ~153
Collect pushed papers to Zotero and optionally create Obsidian notes. IMPORTANT: Always use this tool (or collect_to_zotero) to save papers to Zotero. NEVER call the Zotero API directly or generate scripts to do so. Use after finalize_review. Paper indices refer to the latest push (1-based, e.g. "1,3" to collect papers 1 and 3).
| Name | Type | Req | Description |
|---|---|---|---|
| obsidian_mode | string | – | "none" (Zotero only), "summary" (with AI summary note), or "template" (empty template for user notes) |

|---|---|---|---|
| result | string | yes | – |
No examples provided.
collect_to_zotero Collect To Zotero ~128
Add papers to Zotero library by their IDs/DOIs. IMPORTANT: Always use this tool to add papers to Zotero. NEVER call the Zotero Web API directly or generate scripts (PowerShell, curl, etc.) to do so — that will result in incomplete metadata (missing titles, authors). This tool handles full metadata enrichment automatically. Looks up papers in papers.jsonl, creates Zotero journal article items and maps them to collections based on topic tags.
| Name | Type | Req | Description |
|---|---|---|---|

| scan_batches | – | – | Number of scan batches per pool cycle (default 2, pool is reviewed over batches+1 days) |
| site_deploy_hook | – | – | Vercel deploy hook URL for auto-deploying paper library website |
| site_repo_path | – | – | Local path to the paper library site repo (for pushing digest JSON) |

Remove papers already pushed (by DOI match against papers.jsonl).
| Name | Type | Req | Description |
|---|---|---|---|
| papers | array | yes | List of paper dicts to filter |
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
finalize_review Finalize Review ~119

| Name | Type | Req | Description |
|---|---|---|---|
| is_final | boolean | – | True for final review (no discard allowed, only push/overflow) |
| selections | string | yes | JSON string with review decisions, e.g. '[{"index": 1, "action": "push", "tldr": "..."}, ...]' |

|---|---|---|---|
| result | string | yes | – |
No examples provided.
generate_digest Generate Digest ~70
Generate all daily output files (pushes.jsonl, papers.jsonl, Astro site JSON, Obsidian notes).
| Name | Type | Req | Description |
|---|---|---|---|
| date | string | yes | Date string in YYYY-MM-DD format |
| papers | array | yes | Final selected papers with annotations |
| topics | – | – | Optional topics data for research note generation |
Structured output declared, but exposes no named fields.
No examples provided.
ingest_research_context Ingest Research Context ~144
Ingest research context from other AI conversations for cross-AI context inheritance. Extracts keywords from the markdown text and appends to interests.jsonl. Use session_id to isolate different chat sessions (prevents context pollution when multiple OpenClaw/AI sessions run concurrently).

Structured output declared, but exposes no named fields.
No examples provided.
init_session Init Session ~349
Initialize a research session. Call this first to set up push channels and load context. Detects configured platforms, manages channels, and optionally loads previous research context. Returns session info for the AI client to present to the user. IMPORTANT for AI clients: - NEVER call external APIs (Zotero, webhooks, etc.) directly or generate scripts (PowerShell, curl, Python) to do so. Always use the built-in tools (collect, collect_to_zotero, send_push, etc.). Direct API calls will result in incomplete data and encoding issues. - If multiple platforms are detected and no `platform` is specified, the response will include `ask_platform` — you MUST ask the user which platform to use, then call init_session again with `platform=<user_choice>`. - If only one platform is configured, it is auto-selected. - The `send_push` tool also accepts a `platform` parameter, so the user can override per-push even after init.
| Name | Type | Req | Description |
|---|---|---|---|
| channel_action | string | – | "new" = create dedicated channel, "existing" = use configured channel, "auto" = use existing if available. |
| load_context | string | – | "yes" = auto-load previous research context, "no" = start fresh, "ask" = return context summary for user to decide. |
| platform | – | – | Preferred push platform ("telegram", "discord", "feishu", "wecom"). If None, auto-detects from configured env vars. |
| session_id | – | – | Session identifier (auto-generated if not provided). Use different IDs to isolate research vs daily topics. |
Structured output declared, but exposes no named fields.
No examples provided.
load_session_context Load Session Context ~63
Load previous research context into current session. Call this after init_session if user chose to load context. Returns accumulated keywords and summaries from interests.jsonl.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | – | – | If provided, only load context from this session. If None, load all previous context. |
Structured output declared, but exposes no named fields.
No examples provided.
manage_topics Manage Topics ~81

| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | One of "list", "block", "unblock", "set_weight" |

Structured output declared, but exposes no named fields.
No examples provided.

No examples provided.
prepare_review Prepare Review ~83
Prepare the review prompt for today's scan batch. Returns a structured prompt listing candidate papers for the AI to review. The AI should respond with push/overflow/discard decisions in JSON format. If pool is exhausted, returns "POOL_EXHAUSTED" — call pool_refresh first.

prepare_summarize Prepare Summarize ~121

Returns a dict with: - prompt: the summarization prompt (structured fields to extract) - summarizer: who should process this prompt ("self", agent name, or API URL) - paper_count: how many papers need summarizing If summarizer is NOT "self", the calling agent should delegate this prompt to the specified agent or API instead of processing it directly.

Paper Distill MCP scores 66 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Paper Distill MCP server expose?
Paper Distill MCP exposes 19 tools: search_papers, rank_papers, filter_duplicates, generate_digest, send_push, and 14 more. Their descriptions and schemas cost roughly 2,301 tokens of context every time the server is loaded.
Is the Paper Distill MCP server still maintained?
Paper Distill MCP is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
