Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• list_humor_types open 2h ago

  Return the closed vocabulary of `humor_type` tags used in the index. Useful when you want to filter or reason about candidates by humor mode rather than topic — e.g. a document about endless committees might call for `tech_culture_critique`, while one about feeling outdated might call for `interpersonal_awkwardness`.

• pick_xkcd_for unknown never probed

  Pick the xkcd that best illustrates a document. **Call this first.** The server runs hybrid retrieval (BM25 + vector) over the enriched index and hands back the candidate slate plus the picker brief — same philosophy whatxkcd.com uses on its own LLM. Then **you** (the host LLM) read the brief, reason through the candidates in your own context, and either: - call `render_comic(...)` to draw the rich Prefab UI card (only available on hosts that support the MCP Apps UI extension), or - reply directly with the comic image and your reasoning, using the `image_url` and `page_url` already in the candidate slate. The picker_brief in the response tells you which path to take, based on what your host advertised at MCP `initialize` time.

• search_comics unknown never probed

  Hybrid (BM25 + vector) search over the enriched xkcd index. Returns up to `k` candidate comics ranked by a fusion of keyword and semantic similarity to the query. Each row contains: - num, title, alt, image_url, page_url - applicability: an LLM-written "you'd cite this when..." description - humor_type: a closed-vocab tag (e.g. 'engineer_relatability') - themes: short topical tags - one_line_summary: short prose description Use this as the retrieval step when your agent picks a comic for a document. Construct a query that captures the document's themes, cultural references, or specific topics. Examples: - "the futility of design-by-committee, yet another standard" - "regex parsing edge cases, ISO 8601, time zones" - "feeling old when others don't recognize cultural references" The text channel matches Randall's exact words (titles, alt text, transcripts) for literal-keyword recall; the vector channel matches abstract themes via the LLM-written applicability prose. Both are fused so you get topical and thematic hits in one slate.

• get_comic unknown never probed

  Fetch full details for one xkcd comic by its number. Includes everything search_comics returns plus `transcript` and `explanation` (community-written, from explainxkcd). Use this when you want richer context on a specific candidate before deciding to pick it. Always includes the required CC BY-NC attribution. The image_url is safe to hotlink — that's what xkcd's license explicitly permits.
