## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-03-26; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: list_documents (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_templates (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); send_for_signature (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 588 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 588 tokens to load them all
- tool set hash: 7201e075a4d662c75e9a65a970e881cd
- badge: [![protogrid quality](https://protogrid.dev/badge/app.signsimple/signsimple.svg)](https://protogrid.dev/servers/app.signsimple/signsimple)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `get_document_status`: Check the status of a document previously sent for signature: overall state (sent/completed/declined/expired/voided), per-recipient progress (pending/viewed/signed), and the signed PDF download URL once complete. Requires a SignSimple API key.
- `list_documents`: List the 25 most recent documents sent from the connected SignSimple account, with status and signed-PDF URLs where complete. Requires a SignSimple API key.
- `list_templates`: List SignSimple's free, professionally drafted document templates (NDA, lease, contractor agreement, liability waiver, bill of sale, promissory note). Returns each template's info page and direct PDF URL — pass the PDF URL to send_for_signature as document_url to send one. No API key needed.
- `send_for_signature`: Send a PDF document for legally binding electronic signature via SignSimple (free, unlimited). Provide the PDF as a fetchable URL or base64, plus recipient name(s) and email(s). Each recipient is emailed a secure signing link; signature and date fields are placed automatically unless custom fields are given. Works with the free templates from list_templates (pass their pdf URL as document_url). Requires a SignSimple API key (create one at https://signsimple.app/profile).
