name: pub-search description: Search published writing across AT Protocol platforms (Leaflet, Whitewind, Pckt, Offprint, Greengale). Use when researching prior art, finding tutorials, looking up how others have built things, or discovering announcements and writeups in the atmosphere. user-invocable: true#

pub-search — search the atmosphere's published writing#

Indexes content from Leaflet, Whitewind, Pckt, Offprint, Greengale, and other standard.site publishers. Use it to find prior art when building on atproto.

MCP tools#

Available directly via the bundled MCP server:

tool	what it does
`search`	search writing; `mode` picks the strategy (see below)
`get_document`	fetch full text by AT-URI
`find_similar`	find documents semantically similar to a given URI
`get_tags`	list all tags with counts
`get_stats`	index statistics (document/publication counts)
`get_popular`	popular search queries others have run
`discover_focal_post`	surface notable posts right now (`sort`: trending/top, `window`)
`describe_cluster`	a focal document's semantic neighborhood + cross-platform observations
`recommended_by_top_authors`	what the most-recommended writers themselves endorse

search modes#

search takes a single mode argument (not separate tools):

keyword (default): fast exact match (~100ms), supports all filters
semantic: meaning-based vector search (~500ms), good for natural-language queries
hybrid: both combined via rank fusion — best default for research; results carry a source field

filters#

search args: query, mode, platform (leaflet/pckt/offprint/greengale/whitewind/other), author (DID or handle), limit (default 5, max 40). tag and since (ISO date) are keyword-mode only.

research workflow#

search with mode="hybrid" for the concept
get_document on the best results to read full text
find_similar to expand from a good result
