Feature & Specification Comparison
Tools & Capabilities Breakdown
Vk MCP Server Tools (19)
vk_users_get
Look 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_search
Find 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_get
Read 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_post
Publish 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.
