Connect SignBolt to Claude Desktop, Cursor, Windsurf, or any MCP-compatible AI. Say the word — the agent creates the signing link. You approve every action before it runs.
The Model Context Protocol is Anthropic's open standard for connecting AI agents to external tools. When you add SignBolt's MCP server to Claude Desktop (or any compatible client), the AI can call our API directly during a conversation — with your explicit approval for every tool invocation.
No more copy-pasting emails into forms. No switching tabs. Just tell Claude what you need, approve the call, and the document is on its way.
User approval per call
MCP clients like Claude Desktop show a consent prompt before every tool invocation. Nothing runs automatically. You review what the agent is about to do, then approve or cancel. SignBolt never receives a request unless you click "Allow".
Three tools. Each is one JSON-RPC call. The agent picks the right one based on your instruction.
create_signing_linkBusiness planCreate a signing link for a recipient
Tell your AI: "Send an NDA to john@example.com". The agent calls this tool with the recipient's name, email, and document title. SignBolt generates a signing URL you can forward. Requires a Business-plan API key.
recipient_emailrecipient_namedocument_titlemessage (optional)expires_in_days (optional, default 30)get_signing_statusNo key neededCheck if a document has been signed
Ask: "Has John signed the contract yet?" Pass the audit ID (format: SB-XXXX-XXXX-XXXX from the signed PDF footer) and get back the current status — pending, viewed, signed, or expired — plus timestamps.
audit_idverify_signed_documentNo key neededVerify a signed document's authenticity
Ask: "Verify the NDA we signed last Tuesday." Returns the W3C Verifiable Credential, proof chain, and a public verification URL you can share with a bank, court, or auditor.
audit_idTakes about 60 seconds.
Get a Business-plan API key
The create_signing_link tool requires a Business plan API key. Status and verify tools work without one.
Open Claude Desktop settings
Go to Claude Desktop → Settings → Developer → MCP Servers and paste the configuration below. Replace YOUR_SIGNBOLT_API_KEY with the key from step 1.
{
"mcpServers": {
"signbolt": {
"url": "https://signbolt.au/api/mcp",
"headers": {
"Authorization": "Bearer YOUR_SIGNBOLT_API_KEY"
}
}
}
}The config file is at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS, or %APPDATA%\Claude\claude_desktop_config.json on Windows.
Restart Claude Desktop
Quit and reopen Claude Desktop. You should see a hammer icon (tools available) when starting a new conversation. Type something like "Create a signing link for John Smith at john@acme.com for the NDA" and Claude will invoke create_signing_link after showing you a consent prompt.
Any client that supports Streamable HTTP MCP transport works. The server URL is:
https://signbolt.au/api/mcp
Pass your API key as an Authorization: Bearer header. Check your client's documentation for how to configure custom headers on HTTP MCP servers.
Get a Business-plan API key from your dashboard, paste the config, and you're live in under a minute.
