Hedra MCP Server

What it does

Node MCP server for Hedra's generation API: lip-synced character video from an image plus audio (Character-3), text-to-speech, image generation, and asset/credit management. Its README also advertises third-party models reachable through Hedra Studio, though that list dates from the server's only release and has since drifted from Hedra's own roster.

Field notes

Use `hedra-official` (mcp.hedra.com, shipped 2026-08-31) by default — OAuth instead of a pasted key, the current model roster instead of a frozen one, and Hedra's own quickstart now points MCP clients there. This server has fallen a full API generation behind: Hedra has since launched a v3 API (api.hedra.com/v3, `Authorization: Key <key_id>:<secret>`, billed from a separate prepaid USD wallet), while this server's source still calls the legacy api.hedra.com/web-app/public endpoints with an X-API-Key header. Hedra's v2-to-v3 migration guide says the legacy API remains available for existing integrations with no announced shutdown date, but recommends v3 for anything new — so this works today on borrowed time, and a v3 key will not authenticate it. Billing trap: the legacy API draws on Studio credits plus a paid subscription, and Hedra warns that Studio credits do not fund v3, so do not mix the two up when topping up. Re-checked 2026-10-22: npm mcp-server-hedra is still the only release, 1.0.0 from 2026-02-08; the repo has had no push since that day, MIT, Node 18+, 2 stars — treat it as unmaintained. Its README's /api-profile key link is stale (the page is hedra.com/develop/api-keys) and its third-party model list dates from February. Character-3 itself is alive — it is a v3 model now (`hedra-character-3`), described as Hedra's longform avatar model.
