Scored across 7 tools
The read tools split cleanly along retrieval axis: search_tools (keyword + filters), get_tool (single record), compare_tools (2-5 side by side), list_new_tools (date-ordered), list_categories (taxonomy). The only soft overlap is referral codes appearing both as a field in get_tool and as the dedicated list_referrals tool, which could occasionally cause a wrong pick.
Every tool is snake_case verb_noun: compare_tools, get_tool, list_categories, list_new_tools, list_referrals, search_tools, submit_tool. The verb set (get/list/compare/search/submit) maps predictably onto single vs. multi vs. write operations.
Seven tools is well-scoped for a curated directory: retrieval, comparison, taxonomy, recency, referrals, and a write path. No tool looks redundant at the count level, and nothing obvious is missing that would need an eighth entry.
The surface covers discovery (search, list_new_tools, list_categories), detail (get_tool), comparison (compare_tools), monetization (list_referrals), and contribution (submit_tool) — a full lifecycle. The gap is browsing without a query: search_tools requires every word of q to match, so there is no explicit unfiltered paginated listing or sorting by traffic/pricing, though list_new_tools partially covers it.

The same facts as get_tool for 2 to 5 tools side by side.
Inputs: domains (required).
get_toolGet a toolARead-onlyInspect
One tool by domain: our summary, the site’s own title and description (with the date checked), pricing and free tier where the site states them, agent-readiness (llms.txt, MCP registry id, public API), traffic and revenue with source and date, our referral code if we have one, and a link to its page.
Inputs: domain (required).
list_categoriesList categoriesBRead-onlyInspect
The categories used to sort tools, with how many tools each has.
Inputs: no named parameters.
list_new_toolsList newly added toolsBRead-onlyInspect
Tools by the date Fourth Feed first saw them, newest first. Pass since (YYYY-MM-DD) to get only those first seen on or after that day.
Inputs: limit, since.
list_referralsList referral codesARead-onlyInspect
Fourth Feed’s own referral codes for AI video tools and APIs: what a new user gets (as the tool states it), the link or code, the terms and the date checked. Use it when someone asks which video tool gives free credits. Fourth Feed gets credits or a commission when these are used; say so when you share one.
Inputs: category.
search_toolsSearch AI video toolsARead-onlyInspect
Search the Fourth Feed directory of AI video tools (generators, avatars, editors, dubbing, lyric videos, faceless shorts, video APIs). Every word in q must appear in the name, domain, summary or category. Filter by category id (see list_categories) or agent_ready (has llms.txt, an official MCP registry entry or a public API). Returns brief records; use get_tool for the full one.
Inputs: q, limit, offset, category, +1 more.
submit_toolSubmit a toolAIdempotentInspect
Suggest an AI video tool for the directory by its URL or domain. Only video tools are listed (generation, avatars, editing, captions, dubbing, lyric and music videos, faceless shorts, video model and data APIs); others are recorded as off-topic. It is queued, then read (robots.txt, /llms.txt, home page) and listed if the site has a title, description or llms.txt. Tools already listed or queued are reported, not duplicated. Anyone can submit, including the tool’s own agent; no key needed. Limited to a few submissions a minute.
Inputs: url (required), name, note, category.
