MCP tools

Connect a compatible client to https://mcp.atlaswork.ai/mcp. The client lists the typed schemas and calls tools through MCP; these are not REST endpoints.

​

Sending

​

send_contract_for_review

Creates a review-first envelope. Supply parties[] and exactly one intake:

• document_text for a contract drafted in chat
• document_url for a public PDF or DOCX
• document_id to reuse an existing Atlas envelope’s source document
• document_file for a host-provided attachment
• request_document_upload: true for a one-shot upload URL

Optional document_filename preserves the source filename and document_name sets the human-facing contract name. The result includes envelope_id, review_url, lifecycle/detection status, and the v2 envelope graph. A human approves the review before signing emails are sent.

​

complete_upload_session

After the user uploads to a needs_document.upload_url, pass its upload_session. Atlas verifies and hashes the bytes, anchors the original document, and starts field detection. Repeating completion is safe.

​

send_contract_from_template

Creates an envelope from a saved template’s pinned layout. Call get_template first, then supply template_id and one party for each parties_for_send.role_name. auto_send defaults to true; pass false for a review-first draft. prefill_map accepts keys advertised by the template.

​

Templates

​

list_templates

Lists reusable templates with readiness, status, subtitle, usage, and cursor pagination fields.

​

get_template

Returns parties_for_send, stored_signatures, template_roles, optional_prefill_keys, signer_field_count, do_not_include_in_parties, and an example_create payload.

​

Reading and status

​

get_envelope

Returns the full v2 envelope graph plus model-friendly snake_case lifecycle, party, field, document, and timestamp fields.

​

check_signing_status

Lightweight polling surface: status, signed count, next signer, terminal state, and upload receipt.

​

list_envelopes

Lists envelopes newest first. Filters accept v2 statuses and the familiar aliases pending → in_progress and signed → completed. Page size defaults to 20 and is capped at 100.

​

extract_contract_data

Returns not_extracted until the envelope is complete, then returns structured parties, lifecycle and semantic dates, governing law, and labeled field values.

​

Lifecycle

​

remind_signer

Emails the next unsigned signer after the envelope has been approved and sent. Atlas enforces reminder rate limits.

​

void_envelope

Cancels a non-terminal envelope so it can no longer be signed. This tool is marked destructive and accepts an optional reason.

​

Reliability

Mutating tools accept idempotency_key; reuse the same value when retrying the same intended operation. Atlas errors are returned as MCP tool errors with stable API codes and actionable messages.
