It both reads and writes, but writing is deliberately narrow. The two authoring abilities can only ever produce drafts — there is no status parameter anywhere in the plugin — and only for post types on an explicit allowlist. Publishing stays a human act.

Key features

• Retrieve a single post by ID or slug, returned as both Markdown and raw block markup.
• List posts of any registered post type, with pagination, status filtering and field subsetting.
• Discover the registered public post types before querying them.
• Author new drafts, and revise existing ones, from Markdown or HTML — never publishing, never touching content that is already live.
• Search users by ID, email, or name, with priority-ranked matching.
• Discover and read MCP resource-typed abilities without a human attaching them by hand.

Install and setup

Network-activate the plugin. No configuration is required; abilities become available to any MCP connector whose authenticated account holds the required capability. LH MCP Block Transformer is an optional dependency used for content conversion — without it, post content can still be read raw but not rendered as Markdown, and the authoring abilities cannot accept content.

No admin UI, no front-end output — abilities only. Network-activated, so every ability is reachable via each site’s own MCP connector, not just the main site.

Key features

• Group membership queries: who’s in a group, their role, and (where permitted) their email
• Group listing and lookup, independent of any taxonomy
• Activity-stream queries, scoped to a group or a single user
• Member directory search, matching BuddyPress’s own directory tabs (active/newest/alphabetical/online/random)
• Seven read-only MCP abilities in total, deliberately excluding private messages and friend connections — a different risk category, out of scope here

Capability model

Abilities that never return an email address are gated to BuddyPress’s own bp_moderate capability. Abilities that return member email addresses (get-group-members, search-members) are gated to edit_users instead, matching the precedent set by lh-membership/list-members. Full per-ability detail is in the MCP abilities section below.

Install & setup

1. Upload/install the plugin as lh-mcp-buddypress-queries.
2. Activate on any site running BuddyPress. No configuration needed — abilities register automatically.
