Docuprox

MCP (Model Context Protocol) server for the DocuProx document-processing API. Exposes DocuProx as tools that any MCP-compatible AI client can call — Claude Desktop, Claude Code, Cursor, Windsurf, and more.

---

Quickstart (npx — no install required)

DOCUPROX_API_KEY=your_key DOCUPROX_BASE_URL=https://api.docuprox.com/v1 npx docuprox-mcp

Requires Node.js ≥ 18.

Configuration

Variable	Required	Description
DOCUPROX_API_KEY	yes	Your DocuProx API key
DOCUPROX_BASE_URL	yes	Base URL of the DocuProx API (e.g. https://api.docuprox.com/v1)

Available Tools

process_job

Submit a document for asynchronous processing. Returns a job_id to track with poll_job or job_results.

Argument	Type	Required	Description
file_path	string	yes	Path to file on disk (jpg, png, pdf, zip)
template_id	string	no	UUID of a DocuProx template
document_type	string	no*	Document category — required when no template_id
prompt_json	object	no	Custom extraction schema
custom_instructions	string	no	Free-text guidance for the AI
static_values	object	no	Key-value overrides for STATIC template placeholders

Example: "Submit the invoice at /tmp/invoice.pdf using template 123e4567-e89b-12d3-a456-426614174000"

---

process_agent

Submit a document for synchronous extraction. Blocks until done and returns results directly — no polling needed. Credits are automatically refunded on failure.

Argument	Type	Required	Description
file_path	string	yes	Path to file on disk
prompt_json	object	yes	Extraction schema
document_type	string	yes	Document category
custom_instructions	string	no	Free-text guidance
static_values	object	no	Key-value STATIC overrides

Example: "Extract passport data from /home/user/passport.jpg. Use document_type='passport' and prompt_json { 'name': 'full name', 'dob': 'date of birth' }"

---

job_status

Check the status of an async job.

Argument	Type	Required	Description
job_id	string	yes	UUID from process_job

Returns: { job_id, status } where status is one of: NEW → UNZIP FILE → UNZIP FILE SUCCESS / UNZIP FILE FAILED → PROCESS IMAGE → PROCESS IMAGE SUCCESS / PROCESS IMAGE FAILED → SUCCESS / FAILED

---

poll_job

Block until a job finishes (or times out). Retries job_status internally on a timer.

Argument	Type	Required	Default	Description
job_id	string	yes	—	UUID from process_job
interval_ms	number	no	3000	Poll interval in ms
timeout_ms	number	no	300000	Max wait in ms (5 min)

Example: "Submit /tmp/batch.zip then wait for the result" — Claude will call process_job then poll_job automatically.

---

job_results

Fetch the extracted results of a completed async job.

Argument	Type	Required	Default	Description
job_id	string	yes	—	UUID from process_job
result_format	string	no	"json"	Output format: "json" or "csv"

Example: "Get the results for job 0869d5ec-5cfe-4960-878d-8b4ec1900726 in CSV format"

How File Uploads Work

Every tool that accepts a file_path:

1. Resolves it to an absolute path
2. Reads the file into a Buffer
3. Detects MIME type from the file extension
4. Sends it as multipart/form-data with field name actual_image

The AI never sees or handles base64 — just pass a local file path.

---

Error Handling

Error	Cause
File not found	file_path does not exist — a clear message with the resolved path is returned
API error	HTTP status + response body surfaced in the tool result
Invalid arguments	Zod validation fires before any API call
Credit failure	402/403 from /process-agent surfaced clearly
