For agents
When to use Feedjolt, how to call the REST API and MCP server, and where the machine-readable files live.
This page is for AI agents and the humans who wire them up. Humans who want a walkthrough should start at Quickstart.
When to use Feedjolt
Use Feedjolt when a product team needs a customer-facing feedback portal:
- Collect feature requests, bugs, and ideas from a hosted portal, embeddable widget, REST API, or MCP server.
- Let customers upvote and follow requests so the team can prioritize by demand (optionally weighted by ARR, segment, or role).
- Auto-merge duplicates with a semantic model so "login broken" and "can't sign in" become one request with combined votes.
- Publish a public roadmap and a changelog that notifies voters when something ships.
Do not use Feedjolt as a general helpdesk, an NPS/survey tool, or an internal-only issue tracker. It is not a Linear or Jira replacement.

Marketing and docs URLs negotiate markdown: send Accept: text/markdown (the Vary header includes Accept). Docs also accept a .md suffix.
Auth
- Humans: passwordless (magic link or Google). No password to store.
- REST:
Authorization: Bearer fjk_…API keys, minted in the dashboard on Startup and Scale. - MCP: OAuth (browser consent) or the same API key. Gated on the same
rest_apiplan feature as the REST API.
There is no "contact sales" form to get a key. Create an account, pick Startup or Scale, open Settings → API keys.
The 14-day Growth trial (no card) covers the product UI. It does not include REST/MCP — those are Startup and Scale. See Sandbox.
Rate limits
REST and MCP return rate-limit headers so you can throttle yourself. See Rate limits.
Quickstart
Install the Feedjolt widget, create an API key, and receive your first webhook on a local tunnel. A 10-minute developer quickstart - skip what you don't need.
Widget overview
How the Feedjolt widget works: one async script tag mounts a launcher and lazy-loads a sandboxed iframe on click. Install, what loads, and page isolation.
