API reference

Programmatic access, two surfaces

Everything ClosedLoop AI knows is reachable from code. Query product insights through the MCP's HTTP endpoint, the same tools your AI agents call, and push data in over authenticated webhooks. One workspace, documented tools, no surprise breaking changes.

  • MCP over HTTP
  • OAuth 2.1
  • Webhook ingestion

Your first connection

The read surface is the MCP endpoint. Point any MCP-capable client (or your own code speaking the protocol) at the base URL; auth is OAuth 2.1, auto-discovered:

bashConnect from Claude Code
# US workspace
claude mcp add --transport http closedloop-ai https://mcp.closedloop.sh

# EU workspace
claude mcp add --transport http closedloop-ai https://eu.mcp.closedloop.sh

Any other MCP client works with the same URL. Cursor, Windsurf, Zed, or your own script: add the endpoint, authorize once in the browser, and every tool below is callable.

Built for builders

An open protocol on the way out, authenticated webhooks on the way in. The pieces you check before you commit to an integration.

01 / Read

MCP over HTTP

The Model Context Protocol on standard HTTP transport. Every insight, customer, and opportunity, queryable by tool call.

02 / Auth

OAuth 2.1

Authorization-code flow with PKCE, auto-discovered from the endpoint. API keys authenticate webhook ingestion.

03 / Write

Webhooks in

Push surveys, reviews, and custom feedback into the pipeline over authenticated webhook endpoints provisioned in the app.

Keep keys secret

An API key carries your workspace access. Store it in a secret manager or an environment variable, never in client-side code or version control. Rotate a key the moment it may be exposed.

Referencetools

The tools you'll call first

Every MCP tool is callable from agents and scripts alike. A few of the workhorses, with the full reference in the docs:

ToolDescriptionDocs
get_overview Aggregate counts, trends, and the shape of your feedback over a time window. Docs
search_insights Hybrid search across every product insight, with semantic matching and filters. Docs
search_customers Find customers by name, industry, deal state, churn risk, or insight volume. Docs
search_opportunities Automatically discovered product problems, ranked by business impact and revenue. Docs
get_trends Time-series volume for any topic, category, or feature area. Docs
