Setup
Setup guide
- 11. Open your Switchy workspace settings and navigate to the Integrations tab. 2. Search for Bread & Butter and click Connect. 3. You'll be prompted to paste an API key — generate one in your Bread & Butter dashboard under Settings > API Keys with read access to applications, events, and leads. 4. Paste the key into Switchy and click Authorize. 5. Switchy will verify the connection by fetching your application list. 6. Inside any Project, type '@Bread & Butter list applications' to confirm the integration works. 7. If the response shows your apps, you're ready to query attribution data, event logs, and lead profiles directly from chat.
What teammates see: by default, memories from Bread & Butter are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

@breadandbutter show me the attribution breakdown for last month's conversions by traffic source
Based on the attribution report for your connected application, last month saw 847 conversions across four primary sources: organic search drove 312 conversions (36.8%), paid social contributed 289 (34.1%), direct traffic accounted for 178 (21.0%), and email campaigns generated 68 (8.0%). The report also shows average time-to-conversion was 4.2 days for organic, 1.8 days for paid social, 2.1 days for direct, and 3.6 days for email traffic.
This example demonstrates read-only analytics retrieval. The MCP requires valid API credentials with read access to attribution data. Reporting periods and source granularity depend on your Bread & Butter plan tier; some accounts may see aggregated sources rather than channel-level detail.
@breadandbutter find all leads from the past week who visited our pricing page but haven't converted yet
The query returned 23 lead profiles matching your criteria. All visited /pricing between January 15-22, 2025, but show no conversion event. Notable patterns: 14 leads (60.9%) also viewed /features during the same session, 8 leads returned for a second visit within 48 hours, and 5 leads came from paid search campaigns. The list includes email addresses, first-touch source, and page-view counts for each profile.
This combines the List Leads and List Events tools to filter by behavior and date range. Results depend on your event-tracking configuration—if page views aren't instrumented as events, the MCP cannot filter by URL. Pagination applies; large result sets require multiple queries or cursor handling.
@breadandbutter compare user journey patterns between our top three traffic sources and draft a summary of where each group drops off
Analyzing user-journey insights across organic search, paid social, and direct traffic reveals distinct drop-off patterns. Organic visitors (avg. 5.3 pages/session) most commonly exit after viewing documentation, suggesting content depth meets initial research needs. Paid social users (avg. 2.1 pages/session) drop off at the signup form, indicating possible friction in the conversion flow. Direct traffic (avg. 3.8 pages/session) shows the highest return rate but often exits after the pricing page without proceeding to trial signup. Consider A/B testing the signup form for paid social cohorts and adding pricing FAQs for direct visitors.
This synthesis example pairs the Get User Insights tool with AI reasoning to surface actionable patterns. The MCP provides aggregate metrics; the AI interprets trends and suggests next steps. Insight granularity varies by plan—geography and top-page breakdowns may require a higher-tier subscription.
Use-case deep-dives
When this MCP makes sense for quarterly campaign post-mortems
A 3-person growth team running paid and organic campaigns needs to tie conversions back to sources every quarter. The Get Attribution Report and Get User Insights tools pull the metrics they already track in Bread & Butter—no spreadsheet exports, no manual pivot tables. If your team reviews attribution weekly or daily, this MCP becomes overkill; you'll spend more time prompting the AI than just opening the dashboard. But for quarterly or monthly deep-dives where you're comparing multiple reporting periods or cross-referencing top pages with geography, the MCP saves 20 minutes of tab-switching and lets you ask follow-up questions in plain English. Best fit: teams that treat attribution as a periodic analysis task, not a live monitoring dashboard.
Why this MCP works for one-off audience pulls
A solo founder or 2-person marketing team needs to pull a lead segment—say, all visitors from the last 30 days who hit the pricing page but didn't convert. The List Leads and List Events tools let you filter and cross-reference without writing SQL or waiting on a data analyst. The catch: if you're doing this daily or running complex multi-step funnels, you'll hit the pagination ceiling fast (the MCP returns one page at a time with a cursor). For occasional segmentation—prepping a launch email, building a re-engagement list, auditing lead quality—this MCP turns a 10-minute CSV export into a 2-minute conversational query. Skip it if your CRM already handles segmentation or if you need real-time sync.
When this MCP speeds up implementation QA
A product manager or junior engineer is setting up Bread & Butter for the first time and needs to confirm that event definitions are firing correctly. The List Event Definitions and List Events tools let you inspect what's configured and spot-check recent activity without toggling between docs and the admin UI. This is a narrow window—once tracking is stable, you won't touch these tools again for months. But during the first week of integration, the MCP cuts the feedback loop from 5 minutes (open dashboard, filter, screenshot, Slack) to 30 seconds (ask the AI, get the answer inline). Only worth the API-key setup if you're onboarding multiple apps or doing frequent event-schema changes; otherwise, just use the web UI.
Frequently asked
What does the Bread & Butter MCP do in Switchy?
It pulls attribution data, event tracking, and lead profiles from your Bread & Butter account into Switchy's AI workspace. Your team can query conversion sources, visitor journeys, and lead lists without opening the Bread & Butter dashboard. Useful for marketing ops and growth teams who need to reference campaign performance or user behavior during planning sessions.
Do I need admin access to connect Bread & Butter?
You need an API key with read access to your Bread & Butter application. The MCP doesn't write data, so editor or viewer-level keys work fine. If your account restricts API key creation to admins, ask them to generate one for you. The key stays in Switchy; your team members don't see it.
Can the MCP create or edit events in Bread & Butter?
No. It only reads existing event definitions, attribution reports, and lead data. If you need to configure new events or update lead lists, do that in the Bread & Butter dashboard. The MCP is for analysis and reporting inside Switchy, not for campaign setup or data management.
How is this different from exporting CSV reports from Bread & Butter?
The MCP fetches live data on demand, so you're never working from a stale export. You can ask Switchy to compare attribution across date ranges or filter leads by criteria without manually downloading and merging files. It's faster for ad-hoc questions, but the Bread & Butter UI is still better for deep-dive segmentation.
Who on the team should connect this integration?
Whoever owns your Bread & Butter account and has API key access. Once connected, any Switchy workspace member can query the data through the AI assistant. The connection doesn't count as a separate user seat in Bread & Butter, and it doesn't affect your Switchy plan limits.
