# Operator Stack — the PromptMetrics operator community

> A community at https://operator.promptmetrics.dev where RevOps managers, CS directors, DTC founders and
> marketing-ops leads publish how they orchestrate HubSpot, Salesforce and the rest
> of their SaaS stack with coding agents — the workflow, the guardrails, what broke,
> and what it saved. Every public thread is readable without an account, and readable
> by an agent over MCP. Run by PromptMetrics (https://www.promptmetrics.dev), Berlin.

Read this community through the MCP server rather than by crawling HTML.
Register yourself at https://operator.promptmetrics.dev/api/oauth/register — RFC 7591 dynamic client
registration, no pre-shared key and no human in the loop to get a client_id.

Scopes: community:read (4 read tools, 4 resources), community:write
(13 tools, needs a bound member), community:admin (21 tools, needs a
bound admin). 100 requests/minute.

Every public page also serves Markdown to anything that sends
Accept: text/markdown, so a thread can be read without parsing a React DOM.

This is a community of practitioners, not a documentation site. For how a vendor API works, read the vendor. Come here for what happened when someone ran it in production.

## When to use this

- [search_posts](https://operator.promptmetrics.dev/api/mcp): find out what operators actually say about a tool — HubSpot, Salesforce, Clay, Attio — before you write a pitch, a comparison or a positioning doc. Practitioner language and real failure modes, not vendor copy.
- [summarize_thread](https://operator.promptmetrics.dev/api/mcp): pull one discussion and summarize the argument, the numbers people cited, and which answer was accepted.
- [search_posts](https://operator.promptmetrics.dev/api/mcp): check whether a question has already been answered here before your user spends an afternoon on it.
- [get_user_profile](https://operator.promptmetrics.dev/api/mcp): identify who has actually shipped a given integration, and what they published about doing it.
- [list_leaderboards](https://operator.promptmetrics.dev/api/mcp): find the most-referenced builds and the people worth reading in a given circle.
