About Plain
Plain is a B2B customer-support platform built around threads, with an API for most of what the app does.
clariBI reaches your Plain workspace through the official Plain MCP server (generally available since March 2026): threads, customers, tenants, help-center articles, labels, and workspace data. Reads inherit the connected user's Plain permissions. Write tools (reply, assign, snooze, mark-done) are filtered out at the catalog layer; clariBI only reads.
Vendor site: plain.com
What clariBI can read
Plain exposes 30 granular tools across five domains. clariBI's planner gets the read surface only; write actions (reply, assign, snooze, mark done, upsert) are filtered out at the catalog layer before the planner ever sees them.
Threads (the support conversations)
Fetch and search support threads. Pull full details for a single thread including its replies, labels, assignee, status, and customer reference.
Reads enabled: fetch_thread, search_threads, get_thread_details
Customers (who's writing in)
Fetch customer profiles by email or ID, search by attributes, and list all threads associated with a customer for retention and concentration analysis.
Reads enabled: fetch_customer, search_customers, list_customer_threads
Tenants (the customer's company)
Fetch tenant records with the firm-level metadata Plain tracks (plan tier, ARR, contract value). Useful for tying support volume to revenue tier.
Reads enabled: fetch_tenant, search_tenants
Help Center & Workspace
Read help-center articles by ID or slug; surface workspace metadata and label definitions. Lets clariBI ground tickets against the published self-serve content.
Reads enabled: get_help_center_article, list_labels, get_workspace
Plain is one of 86 apps in the clariBI MCP catalog. See the catalog

How to connect Plain
Open Data Sources in clariBI
In clariBI, go to Data Sources > Add Data Source > MCP Servers tab. Find Plain in the catalog and click Connect.
Authorize with Plain (OAuth + PKCE)
A Plain OAuth popup opens with your Plain user's permissions inherited. No API keys to manage. Approve. clariBI stores credentials stored encrypted.
Ask questions, get dashboards
clariBI surfaces ticket volume, first-response time, customer-tier breakdowns, and theme mix. Ask "Which customer tiers drove the most tickets in November?" or "What's the median first-response time on bug-tagged threads?", and clariBI reads Plain alongside Stripe, HubSpot, and your other sources.
Questions you can ask
Asking in plain English uses AI credits. The AI decides which Plain tools to call, totals are computed from the rows they return, and the AI writes the explanation.
- "Which Stripe customers churned in Q3 had open bug-tagged threads in the 30 days before cancel?"
- "What's our support-cost-to-ARR ratio for each customer tier?"
- "Which support themes have spiked the most week-over-week and which features do they map to?"
About the Plain connector
Which Plain plan do I need?
Any Plan tier that exposes the public API. Plain's MCP server went generally available in March 2026; if you can reach the API today, the MCP server is enabled on your workspace.
Does clariBI inherit my Plain permissions?
Yes. Plain MCP uses OAuth 2.0 with PKCE and ties to your specific Plain user. Whatever threads, customers, tenants, and labels your account can see in Plain, clariBI can read. Whatever's hidden by Plain's role model stays hidden in clariBI.
Can clariBI reply to threads, assign tickets, or change status?
No. Plain exposes write tools (reply, assign, snooze, mark done, upsert) but clariBI's catalog layer filters them out before the planner ever sees them.
Are API keys involved anywhere?
No. Plain's OAuth + PKCE flow handles auth end-to-end. No tokens, secrets, or API keys are stored in clariBI by the user; DCR-style credentials are issued and managed automatically.
My Plain workspace is US-hosted. Does that matter?
No. The remote MCP endpoint at mcp.plain.com/mcp routes to the right region transparently. Both US-hosted and EU-hosted workspaces work without additional configuration.
Which clariBI plans include Plain?
Plain needs a Starter, Professional or Enterprise plan. MCP apps are not part of the Free or Lite plans. The 14-day trial does not include it.
Try Plain in clariBI
Plain needs the Starter plan ($99 a month) or above. The 14-day trial does not include it, but you can use the trial to try the rest of clariBI first.
