How do I install the postwire mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `POSTWIRE_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

Tool	What it does
generate_posts	Smart Distribute. One prompt → a draft written for each platform: character limits, hashtag conventions, YouTube SEO title+tags, hook-first captions for TikTok,
post_to_social	Publishes. Takes one text for all, or per_platform drafts from generate_posts.
get_post_status	Publish state for platforms that report one back (TikTok and YouTube process asynchronously).
list_platforms	Every supported network and the fields it needs. Works without a key.
my_account	Plan, posts used this month, which accounts are connected.
