LaunchDarkly
Add LaunchDarkly to your product for your customers, and give your AI agents governed access to it.
Embed a LaunchDarkly integration so your customers can see and change their own feature flags from inside your product rather than switching consoles. Each customer authenticates their own LaunchDarkly account, so reads and writes run under their permissions and every change is attributable. fastn handles per-customer credentials, rate limits, pagination and API upkeep, and events can be replayed after an outage so a webhook missed during downtime is not silently lost.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers connect their own LaunchDarkly project so your product reads which flags are on for them.
Create or update a flag and its targeting rules from your product once a customer approves the change.
Read projects, environments and flag states so your product shows what is enabled where.
React to a flag change so your product logs it or notifies the right team in real time.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent checks which flags are enabled for an environment before answering a support question.
An agent toggles a flag within governed permissions, with the change audited and attributable.
An agent reads the audit history to explain who changed a flag and when.
Example prompt
List the flags enabled in production for this project and show which ones changed in the last week.
Set up LaunchDarkly in 4 steps
- 01Open the LaunchDarkly connector from your fastn dashboard.
- 02Have each customer authenticate their own LaunchDarkly account with least-privilege scopes.
- 03Map the projects, environments and flags your product uses, then enable actions and triggers.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the LaunchDarkly integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a LaunchDarkly integration without building it. Your customers connect their own LaunchDarkly account inside your product and work their services, builds and deployments there, with no per-customer code on your side.
- Handle the part that actually costs time: these systems emit a lot of webhooks, and replay after downtime has to be handled. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a LaunchDarkly update is not your on-call problem.
- One integration serves your product and your agents. The same governed LaunchDarkly connection powers in-product features and gives AI agents scoped, audited access, so you connect engineering activity to the rest of the business without wiring it twice.

PostgreSQLLaunchDarkly integration FAQ
How do I add a LaunchDarkly integration to my product?
Enable the LaunchDarkly connector in your fastn dashboard, then let each customer authenticate their own LaunchDarkly account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no LaunchDarkly client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own LaunchDarkly account?
Yes. Every connection is scoped to the individual customer, so each authorises their own LaunchDarkly account and only ever sees their own services, builds and deployments. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this LaunchDarkly integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent checks which flags are enabled for an environment before answering a support question.
Who maintains the LaunchDarkly integration?
fastn does. When LaunchDarkly changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Can I react to LaunchDarkly events in real time?
Yes, through event triggers. Events are delivered per tenant and can be replayed after an outage, so a webhook missed during downtime is not silently lost.
Can an agent open or update items in LaunchDarkly?
Yes, within scoped permissions, and every action is audited so an agent's changes are attributable.
What can I build with the LaunchDarkly integration?
A common starting point: connect their own LaunchDarkly project so your product reads which flags are on for them. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the LaunchDarkly integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding LaunchDarkly does not change your per-connector cost. You can start free with 3 connected accounts.
Add LaunchDarkly to your product
Start free with 3 connected accounts. No sales call required, and no per-customer integration code.
