Query receipts

Every query can be deposited to an append-only, hash-chained JSONL log by openalex_mcp.ledger. It is off unless MCP_RECEIPT_LOG is set, and a logging failure is swallowed rather than raised — a search matters more than the record of it. Secrets are redacted before a line is composed.

MCP_RECEIPT_LOG=C:\path\to\receipts.jsonl
MCP_RECEIPT_SESSION=project-or-article-slug
MCP_RECEIPT_STRICT=1        # optional: make logging failure raise

Verify a deposited log's hash chain:

python ledger.py verify receipts.jsonl

MCP SDK compatibility

Runs on both mcp 1.x and 2.x. Version 2.0.0 of the SDK removed mcp.server.fastmcp; this server imports FastMCP where it exists and falls back to MCPServer where it does not.
