Integration
Connect PostHog to Harness.io
When Action Performed fires in PostHog, your agent runs Create Project in Harness.io. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.
What do you want PostHog and Harness.io to do together?
Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.
Set it up in your client
Claude Code
Run this in the directory you want to work in.
claude mcp add --transport http -s project apiant-ai https://mcp.apiant.aiStart Claude Code there, approve the server, and sign in in the browser page it opens.
Claude Code guide (opens in a new tab)Claude, web and desktop
Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first.
Setup guide (opens in a new tab)Cursor
Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser.

Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server.
Setup guide (opens in a new tab)Codex and the ChatGPT desktop app
Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.
Setup guide (opens in a new tab)Any other MCP client
Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.
Setup guide (opens in a new tab)PostHog tells you what people do in your product; Harness.io runs the pipelines that ship it. Connecting them lets a product action in PostHog check a person, a cohort or a feature flag and then act in Harness.io — run a pipeline, look up an execution's status, or add an environment or secret — and write the result back as a PostHog annotation.

Questions
PostHog and Harness.io, answered
Which side starts the workflow?
PostHog starts it, through the Action Performed trigger, since Harness.io has no triggers listed here. Harness.io is the acting side: executing a pipeline, fetching a pipeline or execution, listing executions, or creating a project, environment, secret or connector.
Can I run a Harness.io pipeline only for certain users or flag states?
Yes. After the PostHog action fires you can get the person or evaluate their feature flags in PostHog, and execute the pipeline in Harness.io only when the condition you set holds.
What can start an automation from PostHog?
Any of PostHog's 1 trigger in the catalog, including Action Performed. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Harness.io when something happens in PostHog?
Any of Harness.io's 11 actions, including Add Environment, Add Secret, List Pipeline Executions and Create Project. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Harness.io to PostHog?
Harness.io has no triggers in the catalog today, so automations start in PostHog. If you need the other direction, ask: your agent reads Harness.io's API documentation and adds it.
Do I have to build a connector for PostHog or Harness.io?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use PostHog and Harness.io without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
