Overview

Description from the maker (original English)

Read Click2Mail credit, jobs, costs and tracking; upload documents, create and submit mail jobs.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 22 things (tools) click2mail_get_credit, click2mail_list_return_addresses, click2mail_get_product_options, click2mail_estimate_cost …
  • The registry lists no key to fill in.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • click2mail_estimate_cost

  • click2mail_list_documents

    List the documents uploaded to the account (id, name, class, pages), most recent first. Use a document id when creating a job. GET /molpro/documents.

  • click2mail_get_address_list

    Status of an uploaded address list: processing state (3 = CASS-standardized and ready for a job), name and counts. GET /molpro/addressLists/{id}.

  • click2mail_check_addresses

    Validate and standardize up to 100 US postal addresses (USPS/CASS correction) before mailing. Read-only: nothing is saved or sent. POST /molpro/addressCorrection.

  • click2mail_create_address_list

    WRITE: upload a recipient address list (up to 500 addresses) to the account. The list is standardized (CASS) by Click2Mail; poll click2mail_get_address_list until status 3, then use its id in click2mail_create_job. Creates data only; nothing is mailed or charged. POST /molpro/add

  • click2mail_upload_document_from_url

    WRITE: have Click2Mail fetch a PDF (or other supported file) from a public http(s) URL and store it as a document on the account. Returns the document id for click2mail_create_job. Creates data only; nothing is mailed or charged. POST /molpro/documents/url.

  • click2mail_list_projects

    List the account's projects (jobs are grouped by project; jobs without one are grouped by month, e.g. "March 2022"), most recently updated first. Use a project name with click2mail_list_project_jobs. GET /molpro/projects.

  • click2mail_list_project_jobs

    List the mailing jobs of one project (id, status, description). This is how to see the account's jobs: pick a project from click2mail_list_projects. GET /molpro/projects/jobs.

  • click2mail_list_jobs_by_app_signature

    Full details of a job: print options, document, address list, dates, cost and payment. GET /molpro/jobs/info/{id}.

  • click2mail_get_job_tracking

    USPS tracking for a submitted job: per mail piece barcode, address, status, date and location. Tracking updates once a day, so one call per day is enough; nothing is tracked on staging. GET /molpro/jobs/{id}/tracking.

  • click2mail_get_job_cost

    The exact cost of a created job (postage, printing, fees) for a payment type. Read it before click2mail_submit_job. GET /molpro/jobs/{id}/cost.

  • click2mail_create_job

    WRITE: create a mailing job from an uploaded document and an address list. The job stays a draft (status Editing): nothing is printed, mailed or charged until click2mail_submit_job. Use the exact option strings from click2mail_get_product_options. Returns the job id. POST /molpro

  • click2mail_request_job_proof

  • click2mail_submit_job

    WRITE, SPENDS MONEY, NOT REVERSIBLE: submit a draft job for printing and USPS mailing. This charges postage and printing to the account (User Credit = prepaid balance, or Invoice) and the physical mail is sent to every recipient. Before calling: read click2mail_get_job_cost and c

  • click2mail_cancel_job

    WRITE: cancel a SUBMITTED job. The vendor documents this only for jobs paid by invoice and only before processing for mailing has started; otherwise it fails. The mailing is stopped for good, so get the user's explicit go-ahead first; `confirm` must be true. To remove a draft use

  • click2mail_delete_job

    WRITE: delete a job that has not been submitted (status Editing or PendingProofAcceptence). Submitted jobs cannot be deleted; use click2mail_cancel_job. POST /molpro/jobs/{id}/delete.

Common questions

Is Click2Mail MCP by usefulapi safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.14.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, LickityClick
