MCP server

Use DocketLayer directly from Claude and other AI agents via the Model Context Protocol.

DocketLayer exposes a remote MCP server at POST /v2/mcp. Any MCP-compatible client — Claude Code, Claude Desktop, or any agent using the MCP Streamable HTTP transport — can connect directly. No package installation required.

Endpoint

POST https://api.docketlayer.ai/v2/mcp

Transport: MCP Streamable HTTP (protocol version 2025-11-25)

Claude Code setup

Add DocketLayer to your Claude Code MCP configuration (~/.claude/mcp.json or project-level .claude/mcp.json):

{
  "mcpServers": {
    "docketlayer": {
      "type": "http",
      "url": "https://api.docketlayer.ai/v2/mcp"
    }
  }
}

No API keys or private keys are required in the configuration. Payment for paid tools is passed per-call via the payment_tx argument (see Payment below).

Claude Desktop setup

In your Claude Desktop configuration file (claude_desktop_config.json):

{
  "mcpServers": {
    "docketlayer": {
      "type": "http",
      "url": "https://api.docketlayer.ai/v2/mcp"
    }
  }
}

Paid tools ($0.99 per call)

Each paid tool accepts a payment_tx argument — a base64-encoded signed Solana USDC transfer of $0.99 to the DocketLayer receiver address. Omit payment_tx to receive structured payment instructions instead of an error (see Payment).

docketlayer_case_query

Queries a case for current context and recent docket activity. Costs $0.99 per call.

Parameter	Type	Required	Description
case_id	string	Yes	Case identifier
court_code	string	Yes	Court identifier
payment_tx	string	No	Base64-encoded signed Solana USDC transfer. Omit to receive payment instructions.
last_checked	string	No	ISO-8601 timestamp. Includes delta block when supplied.
context	string	No	basic or full
language	string	No	en or fr
filing_types	string	No	Comma-separated filing types to filter delta

docketlayer_case_monitor

Checks whether a case has changed since a given timestamp. Slimmer than case_query for high-frequency loops. Costs $0.99 per call.

Parameter	Type	Required	Description
case_id	string	Yes	Case identifier
court_code	string	Yes	Court identifier
last_checked	string	Yes	ISO-8601 timestamp with timezone offset
payment_tx	string	No	Base64-encoded signed Solana USDC transfer. Omit to receive payment instructions.

docketlayer_case_batch

Queries up to 50 cases in a single call. Each successful case costs $0.99.

Parameter	Type	Description
queries	array	Array of query objects — same fields as case_query (excluding payment_tx)
payment_tx	string	Base64-encoded signed Solana USDC transfer. Omit to receive payment instructions.

docketlayer_wallet_info

Returns the configured wallet’s signing-key state and optionally recent callback delivery history.

Parameter	Type	Description
payment_tx_keys	string	Payment for the keys lookup ($0.99). Omit to receive payment instructions.
include_deliveries	boolean	Include callback delivery history. Default: false.
payment_tx_deliveries	string	Payment for delivery history ($0.99). Required when include_deliveries is true.
deliveries_limit	number	Max delivery records to return. Default: 50. Max: 200.

Payment

Paid tools do not require a pre-configured wallet. Instead, each call accepts a payment_tx argument.

If payment_tx is omitted, the tool returns structured payment instructions rather than an error:

{
  "payment_required": true,
  "amount_usdc": "0.99",
  "network": "Solana (mainnet)",
  "recipient": "<receiver_address>",
  "asset": "USDC",
  "next_step": "Create a Solana USDC transfer of 0.99 USDC to <receiver_address>, sign it, base64-encode the signed transaction, and call this tool again with that value as payment_tx."
}

To pay, construct a Solana USDC transfer of exactly $0.99 to the receiver address shown in the instructions, sign it with your wallet, base64-encode the signed transaction bytes, and call the tool again with that value as payment_tx.

See x402 payment protocol for details on constructing payment transactions.

Example usage in Claude

Once configured, you can ask Claude directly:

“Check DocketLayer for any new filings in case 1:24-cv-01234 in the Southern District of New York since January 1st.”

Claude will call docketlayer_case_query. If payment is required, it will relay the payment instructions so you can construct the payment_tx and retry. The three free tools (docketlayer_status, docketlayer_court_list, docketlayer_pricing) work without any payment.
