Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
MCP server for the Dropscan postal mail scanning API: read scanned letters, act on mailings.
These three are never merged into one score: opinions, measurements and popularity are different things.

It passed 1 of 1 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.

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

MCP (Model Context Protocol) server for the Dropscan postal-mail-to-email API. Dropscan receives your physical letters at a scanbox; this server lets your MCP client list mailings, download the scans (PDF / ZIP / envelope image / OCR text), and, when explicitly enabled, request actions (scan / forward / destroy) and manage recipients, forwarding addresses and webhook rules.
mcp-name: io.github.bitterdev/dropscan-mcp
Every request hits the real production account. Actions are irreversible: a destroyed letter is physically shredded and gone, a forward physically mails the letter and costs money.
Because of that, all write/action tools are gated twice:
1/true/yes, every non-GET tool refuses to run. It is disabled by default.confirm argument (default false) and refuses unless it is true.Read-only GET tools are always available and never change state.
| Tool | Endpoint |
|---|---|
list_scanboxes | GET /scanboxes |
list_mailings(scanbox_id, current_status?, older_than?) | GET /scanboxes/{id}/mailings |
get_mailing(scanbox_id, uuid) | GET /scanboxes/{id}/mailings/{uuid} |
get_mailing_pdf(scanbox_id, uuid, save_path?) | GET .../{uuid}/pdf |
get_mailing_zip(scanbox_id, uuid, save_path?) | GET .../{uuid}/zip |
get_mailing_envelope(scanbox_id, uuid, save_path?) | GET .../{uuid}/envelope |
get_mailing_plaintext(scanbox_id, uuid) | GET .../{uuid}/plaintext |
list_recipients(scanbox_id) | GET /scanboxes/{id}/recipients |
get_recipient(scanbox_id, recipient_id) | GET /scanboxes/{id}/recipients/{id} |
get_forwarding_address(address_id) | GET /forwarding_addresses/{id} |
get_shipment(shipment_id) | GET /shipments/{id} |
list_webhook_rules() | GET /webhook_rules |
get_webhook_rule(rule_id) | GET /webhook_rules/{id} |
The download tools save the asset to disk (default ~/Downloads, override with save_path or the DROPSCAN_DOWNLOAD_DIR env var) and return the saved path, byte size and content type.
DROPSCAN_ALLOW_WRITES=1 and confirm=true)| Tool | Endpoint |
|---|---|
request_mailing_action(scanbox_id, mailing_uuid, action_type, forwarding_address_id?, forwarding_date?, confirm) | POST .../{uuid}/action_requests |
cancel_mailing_action(scanbox_id, mailing_uuid, action_request_id, confirm) | DELETE .../{uuid}/action_requests/{id} |
set_mailing_recipient(scanbox_id, mailing_uuid, recipient_id, confirm) | PUT .../{uuid}/recipient |
create_recipient(scanbox_id, type, firstname?, lastname?, name?, confirm) | POST /scanboxes/{id}/recipients |
create_forwarding_address(firstname, lastname, street, number, zip_code, city, country_code, company?, info?, state?, confirm) | POST /forwarding_addresses |
create_webhook_rule(url, events, authorization_header?, confirm) | POST /webhook_rules |
update_webhook_rule(rule_id, url?, events?, authorization_header?, confirm) | PATCH /webhook_rules/{id} |
delete_webhook_rule(rule_id, confirm) | DELETE /webhook_rules/{id} |
`action_type` is one of scan, forward, destroy (exact enum from the API). For forward, both forwarding_address_id and forwarding_date (ISO YYYY-MM-DD) are required.
Webhook `events`: mailing_received, scan_requested, mailing_scanned, mailing_archived, mailing_trashed, mailing_shredded, mailing_added_to_shipment, mailing_removed_from_shipment, shipment_sent, package_tracking_updated.
From a local clone:
python3 -m venv .venv
./.venv/bin/pip install .
The token is read from the DROPSCAN_TOKEN environment variable and sent as Authorization: Bearer . It is never hardcoded.
claude mcp add dropscan -e DROPSCAN_TOKEN="dspat-..." -- dropscan-mcp
{
"mcpServers": { "dropscan": { "command": "/absolute/path/to/dropscan-mcp/.venv/bin/python", "args": ["-m", "dropscan_mcp.server"], "env": { "DROPSCAN_TOKEN": "dspat-..." } } } }
To enable the write/action tools, add "DROPSCAN_ALLOW_WRITES": "1" to env. Leave it out to keep the server strictly read-only.
The server runs over stdio.
| Variable | Description |
|---|---|
DROPSCAN_TOKEN | Required. Dropscan personal access token (Bearer). |
DROPSCAN_ALLOW_WRITES | Set to 1/true to enable write/action tools. Default: disabled. |
DROPSCAN_DOWNLOAD_DIR | Default directory for downloaded PDFs/ZIPs/images. Default: ~/Downloads. |
