Example outputs
Illustrative - representative of the model's voice and quality, not literal recordings.
@PayChasers list all unpaid chases and show me which clients have the oldest outstanding invoices
Found 14 unpaid chases across 9 clients. The three oldest outstanding invoices belong to: Acme Corp (Invoice #2401, 47 days overdue, $3,200), BlueSky Media (Invoice #2389, 38 days overdue, $1,850), and Vertex Solutions (Invoice #2395, 31 days overdue, $4,100). All three chases are in 'active' status with automated reminders running. The remaining 11 chases range from 3 to 28 days overdue, totaling $18,450 in outstanding receivables.
This example demonstrates read-only filtering and AI synthesis of chase data. The list operation has no pagination, so accounts with hundreds of chases may hit truncation limits. The AI can rank and summarize, but the underlying data reflects a point-in-time snapshot with no continuation token for large result sets.
@PayChasers create a new chase for client 'Horizon Design' with invoice #INV-5523 for $2,400 due last Friday, and send the first reminder now
Created chase #CH-8821 for Horizon Design (client auto-created with billing email horizon@example.com). Invoice INV-5523 for $2,400.00 USD is marked 5 days overdue. Initial reminder sent immediately in the default 'polite' tone to horizon@example.com. Automated follow-ups will continue every 3 days until marked paid. Note: Neither the chase nor the client record can be deleted via API if created in error.
This example shows the create-and-send workflow that establishes both a persistent client and an active chase. The immediate send is irreversible, and the client record becomes permanent in your PayChasers account. Always verify recipient details before running this prompt, as there's no undo for the outbound email or the database entries.
@PayChasers mark chase #CH-8804 as paid and draft a thank-you note I can send to the client acknowledging their payment
Chase #CH-8804 (Invoice #2456, $1,750) marked as paid. Automated follow-ups stopped. Here's a draft thank-you note: 'Hi [Client Name], thank you for your prompt payment of Invoice #2456 ($1,750). We've updated our records and truly appreciate your continued partnership. Looking forward to working together on future projects. Best regards, [Your Name]' Feel free to personalize the greeting and closing before sending.
This example pairs a destructive action (marking paid is permanent with no API reversal) with AI drafting assistance. The mark-paid operation immediately halts all reminders, so confirm the payment actually cleared before running this. The AI-generated note is a starting point; always review tone and details for your client relationship context.
Use-case deep-dives
When PayChasers beats manual invoice chasing for solo consultants
A freelance designer working with 8-12 clients per month needs to chase late payments without burning relationship capital. PayChasers wins here because the Create Chase tool sends the first reminder immediately and queues automated follow-ups, removing the mental load of tracking who owes what. The Mark Chase Paid tool stops reminders the moment payment lands, preventing the embarrassing double-ping. The constraint: you can't delete clients or chases through the API, so test your reminder tone carefully before connecting real client emails. If you're chasing more than 10 invoices in a single hour, the Send Follow-Up rate limit will block you—but most freelancers don't hit that threshold. For solo operators who want invoice follow-up off their plate without hiring a bookkeeper, this MCP delivers.
Why PayChasers falls short for multi-client agency billing
A 6-person creative agency managing 30 retainer clients needs visibility into who's current and who's overdue at the start of each week. The List Chases tool returns all chases but offers no pagination or continuation token—if you have 200+ open chases across projects, the API truncates results and you lose visibility. The List Clients tool has the same limitation, making it unreliable for agencies with large rosters. The lack of a delete operation means test chases and duplicate client records accumulate forever, cluttering your workspace. If your agency keeps retainer counts under 50 and you're comfortable with a truncated view, PayChasers can automate the initial reminder. Beyond that scale, you'll need a billing system with proper list pagination and record management.
When PayChasers helps customer success confirm payment status
A 3-person customer success team at a SaaS company fields 'did my payment go through?' tickets daily and needs to check chase status without opening the PayChasers dashboard. The Get Current User tool confirms the connected account, and List Chases filtered by status lets the team verify whether a customer's invoice is marked paid or still in follow-up. The Mark Chase Paid tool gives support reps a one-click way to stop reminders when a customer reports payment outside the system. The trade-off: marking paid is irreversible through the API, so train your team to double-check before clicking. This works for teams handling under 100 chases at a time; beyond that, the truncating list becomes a liability. For small support teams who need quick payment-status lookups during live customer conversations, this MCP closes the loop.
Frequently asked
What does the PayChasers MCP do in Switchy?
It automates payment follow-ups by creating chases, managing client records, and sending reminders through PayChasers. Your AI agents can check which invoices are unpaid, fire off follow-ups in different tones, and mark payments received—all without leaving the conversation. Useful for freelancers and small teams chasing overdue invoices.
Do I need a specific PayChasers plan to connect the MCP?
You need a PayChasers API key, which typically requires a paid plan. The MCP calls Get Current User to verify your account tier and default currency on connection. Check PayChasers' pricing page to confirm API access is included in your subscription before connecting.
Can the MCP delete chases or clients I create by mistake?
No. PayChasers provides no API endpoint to delete chases or clients, so anything your agent creates is permanent in your PayChasers account. Mark Chase Paid is also irreversible—you can't undo it through the API. Double-check prompts before letting agents create records.
How does this compare to logging into PayChasers directly?
The MCP is faster for bulk operations—listing all overdue chases or sending follow-ups to multiple clients in one prompt. But you lose the PayChasers dashboard's filtering and analytics. Use the MCP for routine chasing; use the web app for reporting and manual edits.
Who on the team should connect the PayChasers MCP?
Whoever owns your PayChasers account and handles invoice follow-ups. The API key grants full access to create chases, send emails to clients, and mark payments received. Don't share the connection with team members who shouldn't be sending payment reminders on your behalf.
