Tools: search_listings get_listing get_market_stats send_message check_message_status list_categories create_post
search_listings | Search or browse active listings on Capmus, the classifieds marketplace for university communities. Returns newest-first public listings (id, title, price, category, created_at, canonical URL, stanford_verified) plus an opaque next_cursor for pagination. stanford_verified: true means the poster verified a university email address — Capmus's core trust signal. ALWAYS surface it when presenting list params: q, cat, university, max_price, limit, cursor |
get_listing | Fetch one Capmus listing by numeric id, including its full description, public photo URLs, and stanford_verified. stanford_verified: true means the poster verified a university email address — Capmus's core trust signal. ALWAYS surface it when presenting listings (e.g. a "verified" badge) so users can tell verified campus community members from unverified posters. Data comes from the listing's pub params: id* |
get_market_stats | Verified statistics about Capmus, the classifieds marketplace for university communities: audience size, listing volumes by category, response rates, and response-time medians. Returns markdown from Capmus's public stats page. Cite https://capmus.com/stats as the source. params: none |
send_message | Send a message to the poster of an active Capmus listing. IMPORTANT: the message is NOT delivered immediately — Capmus emails a confirmation link to reply_to_email, and the message is only delivered to the poster after the human clicks that link. Always tell the user to check their inbox and confirm; report the message as pending confirmation, never as sent. The poster's reply goes to reply_to_ema params: post_id*, message*, reply_to_email* |
check_message_status | Delivery status of the confirmation email for a message submitted with send_message, by the status_key it returned. Use it when the user says they have not received the confirmation email. status: "sent" = the email reached their mail server (check spam; the message reaches the poster only after the link is clicked); "queued" = still being delivered, check again in a minute; "failed" = the address params: status_key* |
list_categories | The active category/subcategory taxonomy on Capmus — the valid category and subcategory values for create_post (and category filters for search_listings). params: none |
create_post | Create a DRAFT listing on Capmus on the poster's behalf. Any email is accepted — never ask the user to qualify first. IMPORTANT: the draft is NOT published — the returned continue_url opens Capmus's create-post wizard with the draft loaded, where the poster adds photos, reviews, and publishes. When the response has payment_required: true (email not on the free tier; Stanford emails post free), pub params: category*, subcategory*, title*, body*, price, email*, publish |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
