Tools & capabilities

SpeedContent Social tools 5

generate_social_postWrite a social media post from scratch for a given platform and topic. Use this when you do not already have a draft — for example to produce several variations at once, or for platforms whose conventions you are unsure of. If you have already written the post yourself, prefer score_text and humanize_text, which check and fix your own wording instead of replacing it. Returns a job id immediately — poll it with check_social_job, which usually completes in 20-90 seconds. Costs credits.
score_textCheck how machine-written a piece of text reads, using an external AI detector. Returns a score from 0 to 65 where 0 reads as human and anything above 30 is likely to be flagged. Use this on text you have already written to find out whether it will pass before it is published — it is a measurement you cannot make yourself. Costs 8 credits per call.
humanize_textRewrite text so it no longer reads as machine-written, using an external humanizing service. Use this on your own writing when score_text says it would be flagged. Brand names, domains and any lines listed in `preserve` are restored verbatim afterwards, because the humanizer rewrites whole sentences and splits names. Costs 1 credit per 20 words.
check_social_jobLook up a social post generation job by id. Returns the finished posts once the job completes, or its current progress while it runs. Costs nothing.
list_social_platformsList the platforms generate_social_post supports, with each one's default post length and emoji policy. Costs nothing and makes no network call.

Substack MCP tools 14

get_subscriber_countGet the current subscriber count for your Substack publication. Returns `precision`: 'exact' when the API reports a true count, 'approximate' when only Substack's rounded value is available (the real number is that or higher — render it hedged, e.g. '1,000+'), or 'unavailable' with count -1. Never treat an approximate value as exact.
list_published_postsList published posts with pagination. Returns title, date, slug, and URL for each post.
list_draftsList draft posts. Returns title, creation date, and audience for each draft.
get_postGet the full content of a published post by ID. Returns title, body HTML, metadata.
get_draftGet the full content of a draft post by ID. Returns title, body, metadata.
get_post_commentsGet comments on a published post. Returns commenter name, comment body, date, and reaction counts.
get_sectionsList your publication's sections (categories). Returns each section's id and name. Use a section id as `section_id` when creating or updating a draft to file it under that section.
get_post_analyticsGet performance stats (views, emails sent/delivered/opened, signups, subscribes, estimated value, comments, reactions) for a published post by ID. Substack has no per-post stats endpoint, so this searches your 500 most recent published posts for the ID; returns a not-found note if it isn't among them.
list_scheduled_postsList posts scheduled for future publication, soonest first. Read-only visibility into what's queued — scheduling itself is done in Substack's editor (this server does not schedule, publish, or delete long-form posts). Returns id, title, audience, and scheduled time (`trigger_at`).
create_draftCreate a new draft post. Accepts markdown body which is converted to Substack's format. Does NOT publish — creates a draft only.
update_draftUpdate an existing draft post. Only works on unpublished drafts. Accepts markdown body.
upload_imageUpload an image to Substack's CDN. Provide exactly one of `image_base64` (a base64 data URI) or `image_path` (a local file path). Returns a hosted image URL that is publicly fetchable by anyone with the link (an unlisted asset — not attributed to you or added to your feed).
