Tools & capabilities
Postlint MCP Server tools 3
check_postCheck a social post against one platform's real character limit and report whether it fits. Returns the counted length, the limit, and what drove the count (URLs billed at a fixed width, non-Latin characters billed double, emoji sequences collapsed to one grapheme). Use this before publishing anything with a hard limit — the counting rules are per-platform and are not text.length.check_post_allCheck one post against every platform at once and get a row per platform: counted length, limit, and whether it fits. Use this when deciding where a draft can go as-is. The per-platform arithmetic is included only for the platforms it fails, to keep the response small — call check_post for a single platform's full breakdown.platform_limitsList the platforms this server knows, with each one's limit, the unit it is measured in, why that unit is not a plain character count, and the source the number came from. Use it to explain a result or to see what is covered.
SocialCrawl tools 7
socialcrawl_findStart here: a task in plain words -> the best endpoints (3 by default) of 646, each with the params the task supplies (URLs and @handles resolved), the params still missing, the credit cost and the exact call. With no task it lists platforms, or one platform's endpoints. Free; no key needed.socialcrawl_endpointRead before calling: one endpoint's purpose, params, where the rows are and up to 25 response fields, cost rule, paging, latency, timeout, next endpoints and a sample link. id (or platform+resource, path), a platform slug (its endpoints) or a guide topic. Free.socialcrawl_estimateExact credits before you spend: one call (id, platform+resource or path, plus the params you will send; calls for a job total; items for a walk) or a plan of several calls. Uses the API's estimator when available, else the bundled pricing. A platform slug gives its price table; no id gives the pricing overview. Free.socialcrawl_requestCall one endpoint (platform+resource, or id, or path). Validated locally first (a bad call is free), quoted, refused above max_credits and confirmed above the threshold. A large page is cut at row boundaries; socialcrawl_collect result_id reads the rest. Spends credits; needs SOCIALCRAWL_API_KEY.socialcrawl_collectWalk a paged endpoint (id, platform+resource or path) to `items` unique rows, the last page or max_credits: cursors supplied, duplicates dropped, stops on a 402, refused free when one page exceeds max_credits. Small results come back whole. result_id (+offset, limit, format) reads a stored result, free. Spends credits.socialcrawl_accountFree checks: balance (with this session's spend), transactions (itemised ledger; the receipts for one request_id), status (platform health; read it before retrying a 502/503) and freshness (whether this server's bundled catalogue is behind the API).socialcrawl_manageStateful work by area + action: monitors (scheduled recipes, webhooks, alerts), cohorts (mention search over your own panel of accounts), web (scrape, search, crawl and agent jobs, change monitors, browser sessions) and jobs (Prism background jobs). A wrong field is refused free with the rules. Managing is free; scrapes, jobs, queries and monitor runs bill credits. dry_run: true validates and quotes a create/update and never creates it. rows_new alerts need track (id=monitors).
