social_topic_volumeSOCIAL MEDIA VOLUME as a TIME SERIES: how many posts mention a topic, bucketed by day or hour, so you can see the POST VOLUME TREND and whether SOCIAL CHATTER ABOUT A TOPIC is rising or fading. Answers "how much is X being discussed", "BUZZ OVER TIME for X", "is attention on X growing this week". Returns a per-bucket count broken out by network, running totals, engagement sums where the source exposes them, and an explicit window_actually_covered block. A bucket is a number only where that network was truly measured; where reach ran out it is null, so a measured zero is always distinguishable from an unobserved gap. Coverage is Bluesky, Mastodon, Reddit and Hacker News; X/Twitter is excluded (paid API), so results are a directional proxy over a partial slice of social media rather than total social volume. Examples: topic "bitcoin", days 7, bucket "day" for a week-long attention curve; topic "openai", days 2, bucket "hour", networks ["bluesky","hackernews"] for an intraday spike check.social_account_activityPOSTING CADENCE for one social media account as a TIME SERIES: posts per day over a window, plus average engagement per post and the timestamp of the most recent post. Answers "how often does this account post", "has this account gone quiet", "what is their POST VOLUME TREND", "how active is @someone on social media". The network is inferred from the handle shape (a dotted handle is Bluesky, "@user@instance.tld" is Mastodon, "u/name" is Reddit); when the shape is ambiguous the response lists every network tried in networks_tried. Days with a null count were outside the reach of the feed and stay distinguishable from days with a measured zero. Coverage is Bluesky, Mastodon, Reddit and Hacker News; X/Twitter is excluded (paid API), so results are a directional proxy over a partial slice of social media rather than total social volume. Examples: handle "bsky.app", days 30 for a month of posting cadence; handle "@Mastodon@mastodon.social", days 90 for a long-run activity check.
Vk MCP Server tools 19
vk_users_getLook up VK users by numeric ID or short name (e.g. durov). Use this to resolve a name to an ID before calling other tools, or to check whether a profile is closed.vk_users_searchFind VK users by name, optionally narrowed by city, country, sex or age. Returns matches with a total count; page through them with offset.vk_wall_getRead posts from a user or community wall, newest first. Pass domain for a short address (durov) or owner_id for a numeric one — negative for a community, positive for a person. Each post carries its likes, reposts, comments and views.vk_wall_postPublish a post on a wall. To post in a community, set owner_id to the community ID with a minus sign (-123) and from_group true, otherwise it appears as your personal post on the community wall. Attach media with the attachment string that vk_photos_upload_wall returns. Returns the new post_id.vk_wall_create_commentAdd a comment to a post. owner_id is negative for a community. Returns the new comment_id.vk_wall_get_by_idFetch particular posts by their full IDs in {owner_id}_{post_id} form, e.g. -1_340393. Use it to re-read a post you already know about, such as one you just published.vk_wall_editReplace the text or attachments of an existing post. owner_id is negative for a community. Editing overwrites the previous content, so pass the full new text rather than an addition.vk_wall_deleteDelete a post from a wall. owner_id is negative for a community. This cannot be undone.vk_photos_upload_wallUpload a photo so it can be attached to a post. Takes a URL or a local file path, runs VK's three-step upload, and returns an attachment string like photo-1_2 to pass to vk_wall_post or vk_wall_edit. group_id is positive here, without the minus sign.vk_groups_searchFind communities by keyword, optionally narrowed by type, country, city or sort order. Returns matches with a total count.vk_groups_get_membersList the members of a community. Returns bare user IDs unless you ask for fields, in which case it returns profiles. Many communities hide their member list, which comes back as an access error rather than an empty list.vk_groups_joinJoin a community as the token owner, or send a join request if it is closed. group_id is positive here, without the minus sign.- +7 more on the listing page
