Cotlet is best for real estate investors who work leads in REsimpli and want their AI agent to update statuses, enroll drips and skip trace without running or fixing a server.
Go through the REsimpli leads I called today. Move the accepted offers to Under Contract with the price in a note, move "call me next week" sellers to Follow Up with a call-back task for Sam, and list the ones that should go to Dead Leads so I can pick the reason. Your agent calls list_pipelines, list_leads, get_lead, update_lead_status, add_lead_note and create_task.
Find Dead Leads from the last two quarters whose reason was not "property sold", skip anyone already in an automation, and enroll up to 50 of them in my Reactivation drip this week. Tag them Reactivation Q4. Your agent calls list_pipelines, list_leads, get_lead, list_automations, enroll_lead_in_automation and tag_lead.
Skip trace new leads Runs: Daily
Skip trace the 10 newest leads without a phone number and tell me who matched. Your agent calls list_leads, skip_trace_lead and get_skip_trace_results.
Assign leads and set call-back tasks Runs: Daily
Assign the new Facebook leads to Sam and set a call-back task for tomorrow at 10:00. Your agent calls list_leads, assign_lead and create_task.
Import leads and tag them Runs: Weekly
Add the sellers from driving.csv as leads and tag them D4D October. Your agent calls create_lead and tag_lead.
Endpoints
What is the REsimpli API?
Cotlet's REsimpli API exposes 15 endpoints for your own REsimpli account: list leads, get lead, list pipelines, list automations, get skip trace results, create lead, update lead status, add lead note, tag lead, assign lead, create task, skip trace lead, enroll lead in automation, remove lead from automation and send SMS. The list_leads endpoint returns leads with property address, pipeline, status, assignee and tags. Each endpoint takes simple JSON inputs like lead_id, pipeline_id or automation_id and works both as an MCP tool for agents and as a REST call for scripts.
Leads with property address, pipeline, status, assignee and tags.
read
Lists leads from your account, newest first. Filter by search text, pipeline, status IDs or tag. Pages hold up to 100 leads; raise page for the next one. Use lead_id from each item in the other tools.
Full lead: contacts, property, status, notes, tags, tasks and recent activity.
read
Returns one lead with contacts, property, current status, notes, tags, open tasks, the automations it is in and recent activity. Use it before changing a lead so your agent sees what your team already did.
Your pipelines and the statuses in each, with IDs, as set up in your account.
read
Returns your pipelines in the order set in your account, each with its statuses in order. Names and IDs are yours, not defaults. Use the IDs in list_leads and update_lead_status.
Returns the phone numbers and emails the skip traces on this lead found. A lead with no skip trace returns an empty list. It does not start a skip trace; skip_trace_lead does.
New seller lead with contact details and property address.
write
Creates a lead and returns its ID and the status it starts in. It reaches no one. It runs without asking by default, and delete the lead in REsimpli to undo it.
POST /api/v1/resimpli/create_lead
Input
Input: create_lead
Parameter
Type

POST
update_lead_status
Move a lead to another status, or to a status in another pipeline.
write
Moves one lead to another status and returns the new and previous status. Pass pipeline_id to move it to a status in another pipeline. It reaches no one directly and runs without asking by default; one more call moves the lead back.
Adds and removes tags on one lead in a single call and returns the lead's tags after the change. It runs without asking by default and one more call reverses it.
Assigns the lead to one team member and replaces the current assignee. The call fails if the user_id is not on your team. It runs without asking by default and one more call reassigns it.
Set up a task on a lead with a due time and assignee.
write
Creates a task on the lead with a title, due time and assignee, and returns its ID. The due time needs a time zone. The assignee is you unless you name someone else. It runs without asking by default.

How do I connect REsimpli to Claude Code, Codex or Cursor?
Connecting REsimpli takes three steps: request access, sign in to REsimpli once, then add one MCP server or call the REST API with the same key.
Connect REsimpli over MCP
1
Create an account
Sign up and add REsimpli in the console. Your API key is there too.
2
Sign in to REsimpli once
Open the connect page from the console and sign in to REsimpli the way you always do. We keep the session, never your password, and you can revoke it anytime.
Paste the snippet for your client. The same server and key serve every app you connect, so you do this once.
4
Ask your agent
Prompt
Go through the REsimpli leads I called today. Move the accepted offers to Under Contract with the price in a note, move "call me next week" sellers to Follow Up with a call-back task for Sam, and list the ones that should go to Dead Leads so I can pick the reason.
Ask in plain words. Your agent finds the REsimpli tools on the server and calls them for you; anything that reaches other people waits for your OK unless you switch that off for a tool.
Call REsimpli over REST
1
Export your API key
Shell
export COTLET_API_KEY="cotlet_..."
Your scripts use the same API key as your agent. Keep it in an environment variable, never in your code.
You get plain JSON back, ready for your script. A failed call costs nothing.

Alternatives
Is there a REsimpli MCP server on GitHub?
REsimpli's own Open API is included on every plan and reads records and creates leads, and Zapier covers lead intake. Neither updates a lead or starts an automation. Cotlet works in your signed-in REsimpli account, so it can do what you do in the app.

resimpli.txt
REsimpli has a limited Open API, included on every plan since REsimpli 6.0 (checked 11 Oct 2026). It reads leads, buyers, agents, vendors, call logs and appointments and can create or delete leads, but cannot update a lead's status, notes, tags, tasks or assignment.
Cotlet provides a hosted MCP server and REST API for REsimpli: 15 tools (5 read, 10 write).
Access Request access at https://cotlet.dev/app/signup?app=resimpli; we email the API key.
MCP server https://cotlet.dev/mcp/v1
REST base https://cotlet.dev/api/v1/resimpli
Auth Authorization: Bearer <COTLET_API_KEY>. Listing endpoints and schemas needs no key; calling an endpoint needs one.
Tools list_leads, get_lead, list_pipelines, list_automations, get_skip_trace_results, create_lead, update_lead_status, add_lead_note, tag_lead, assign_lead, create_task, skip_trace_lead, enroll_lead_in_automation, remove_lead_from_automation, send_sms
Confirm skip_trace_lead, enroll_lead_in_automation, send_sms (by default the user approves each call; the user can switch this off per tool, e.g. for scheduled automations)
Markdown https://cotlet.dev/integrations/resimpli-api-mcp-server.md
How access works:
1. The user requests access at https://cotlet.dev/app/signup?app=resimpli (REsimpli is pre-selected). Each request is reviewed and the API key is sent by email.
2. The user signs in to REsimpli once in a browser. An agent cannot do this step.
3. The API key goes into the MCP client or the REST call as a bearer token.
Fits: people who want a hosted REsimpli server that someone else maintains, including non-developers.
Policy: Cotlet never stores passwords, never solves CAPTCHAs, never bypasses MFA.
Company: legal details in the Terms of service at https://cotlet.dev/terms. Contact contact@cotlet.dev.
Session: the user signs in to REsimpli in a browser; Cotlet keeps only the session, AES-256 encrypted, revocable in the dashboard at any time.
Terms: the user stays responsible for following REsimpli's terms; Cotlet is not affiliated with REsimpli.
Can REsimpli automations run on a schedule in n8n, Make or Zapier?
Yes. Cotlet does not replace your automation platform: it gives it a REsimpli connection it does not have, with the same API key as your agent. Write actions ask for your OK by default; switch that off in your dashboard for the tools you choose, for example to update lead statuses and notes after a calling session, and the schedule runs on its own. Cotlet runs in the cloud, so it keeps going while your computer is off.

About Cotlet
How Cotlet holds your access
Cotlet hosts MCP servers and REST APIs for apps with no usable API. Your agent works in your own REsimpli account.
Company details
The legal name, address and registration numbers of the company behind Cotlet are in the Terms of service. Terms
Your session
You sign in to REsimpli yourself, in your browser. We keep only the session, never your password: encrypted with AES-256 in an EU vault, isolated to your account and used only when your agent calls a REsimpli tool you allowed. When it expires, your agent gives you a link to sign in again. Security
Revoking access
Disconnect REsimpli in your dashboard: the session is deleted and access ends at once. Actions that reach other people wait for your OK unless you switch that off per tool.
What we never do
Store passwords, solve CAPTCHAs or bypass MFA.
REsimpli's terms
You use your own REsimpli account and stay responsible for following REsimpli's terms. Cotlet is independent and not affiliated with REsimpli. Terms
Request access and pick REsimpli. Cotlet reviews each request and emails you your API key.
Do I need to be technical?
No. You sign in to REsimpli once in your browser and paste one command into your agent, or one URL into n8n. Your agent can walk you through it. There is no server to install, update or fix.
Is a hosted server safe? My REsimpli session would leave my computer.
Cotlet keeps your REsimpli session encrypted with AES-256 in an EU vault, isolated to your account and used only for the tools you allow: read only, or read and write. The AI model never sees it, and you revoke it in one click. A local server keeps the same session in a file on your computer, readable by any program you run, and needs a fresh sign-in whenever it expires.
Do I need a certain REsimpli plan?
The official Open API is included on every plan (checked 11 Oct 2026). Cotlet works in your own REsimpli account and does not use it; the features you use, such as automations, follow your plan in REsimpli.
Will the official API make Cotlet unnecessary?
It may cover more later. REsimpli lists updates to status, notes, tags, assignment and tasks as planned, and an MCP server as in development with no date. Until then they are not available.
Can my agent post or send messages in REsimpli without asking me?
No. Every call to skip_trace_lead, enroll_lead_in_automation or send_sms waits for your OK by default. For scheduled automations you can switch confirmation off per tool in your dashboard, for example only for approvals. create_lead, update_lead_status, add_lead_note, tag_lead, assign_lead, create_task, remove_lead_from_automation runs without asking, because it sends nothing to anyone and one call undoes it.
Can I use the REsimpli API in n8n?
Yes. Add https://cotlet.dev/mcp/v1 with your API key in n8n's MCP Client node, or call https://cotlet.dev/api/v1/resimpli/{tool} from the HTTP Request node.
