CSR.plus integrations

Connect CSR.plus to any other app, or use it from your AI client over MCP. CSR.plus generates TLS certificate signing requests and their matching private keys over an API, without needing OpenSSL locally. A caller supplies the subject details — common name, organization, organizational unit, locality, state, country and any subject alternative names — plus the key type and size, and receives the PEM-encoded CSR and private key. It can also decode and inspect an existing CSR. No credentials required.

Questions

CSR.plus, answered

Is there a CSR.plus MCP server?

APIANT's MCP server at https://mcp.apiant.ai works with CSR.plus. Add that address to any AI client that takes a remote MCP server, sign in once in your browser, and your client can build, test and run automations that use CSR.plus. Nothing to install.

What can your agent do in CSR.plus?

Any of CSR.plus's 8 actions, including Check SSL, Decode CSR, Find certificate transparency logs and Generate CSR. Your agent maps the data both ways and tests every scenario before it ships.

Which apps can CSR.plus connect to?

Any app in the catalog; the list on this page pairs CSR.plus with each of them. If the other app is missing, point your agent at its API documentation and it builds the connector.

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.
