Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

## MCP tools (1)

### `build_launch_directory_list` (~495 tokens)

Build a list of places to launch a product

Build a ranked list of places to submit a product launch: startup directories, product launch sites, newsletters, communities, subreddits, marketplaces, press and review pages, and optionally curated GitHub lists. Describe the product and each row comes back with the submission link, price, dofollow or nofollow, audience, rules, and a fit score, checked live today (up, moved, parked, gone, login first, submit form, prices shown, newest date on the page) and ranked by Tranco popularity. The places come from the public domain awesome-submitlist catalog. A run that does not succeed is returned as an error with its run ID. Read-only; requires an APIFY_TOKEN and is billed per place row.

Input parameters:

- `categories` (array): Any of ai, analytics, business, community, design, developer-tools, ecommerce, indie, marketing, productivity, saas, social, software, startup.
- `check_live` (boolean|string): Check each place's submission page today. Default true.
- `dofollow_only` (boolean|string): Keep only places marked dofollow. Default false.
- `free_only` (boolean|string): Keep only places marked free. Default false.
- `include_rank` (boolean|string): Add the Tranco popularity rank. Default true.
- `keywords` (array): Extra words to score places by.
- `max_charge_usd` (string): Optional. The run stops before a charge that would pass this amount.
- `max_rows`: Place rows per run. Default 100.
- `min_fit_score`: Keep places scoring at least this, 0 to 100. Needs a description, keywords, or categories. Default 0.
- `only_new` (boolean|string): Skip places an earlier run with the same state_key returned (free). Default false.
- `product_description` (string): What you are launching and who it is for, for example AI meeting notes for B2B sales teams.
- `proxy_mode` (string): auto reads a site that refuses a direct request through the Apify proxy; direct never uses a proxy. A reliability setting; it does not change the price. Default auto.
- `state_key` (string): Optional name for the only new places memory.
- `types` (array): Any of directory, product-launch-site, newsletter, community, subreddit, marketplace, citation, github. Default: all but github.
