Lr Labs MCP server

Lr Labs is a remote MCP server that gives an AI agent 5 tools, among them analyze_cross_border_tax, list_compiled_corridors, lookup_compiled_rule. It answers at https://lrlabs.ai/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 21 October 2026, succeeded.

Deterministic cross-border tax engine: PE, GAAR, Indian TP, rule-level lookup. Compiled law, no LLM.

Description as the publisher wrote it.

The 5 tools Lr Labs offers

Tool	What it does
`analyze_cross_border_tax`	Compute the tax position of a cross-border arrangement between a treaty pair (permanent-establishment exposure and Indian tax liability) from structured facts. Returns a determinate legal position: the answer, the condition tree it stands o Inputs: treaty, facts, question, posture, detail
`list_compiled_corridors`	List which treaty pairs, PE families, and compiled-rule counts the LR Labs engine covers, plus the structured-fact schema. Call this to decide whether analyze_cross_border_tax can answer a question; outside the compiled corridors the engine
`lookup_compiled_rule`	Answer a RULE-LEVEL question directly from compiled law: thresholds and day counts, WITHHOLDING TAX rates on royalty and fees for technical services (treaty and domestic), the 1961→2025 Income-tax Act section renumbering (s.195→s.393(2), s. Inputs: query, treaty
`screen_transfer_pricing`	Screen an Indian transfer-pricing position deterministically: safe-harbour eligibility against the Rule 10TD floors (17%/18% software-ITES, 18-24% KPO), documentation obligations under Rule 10D, which transfer-pricing METHODS are eligible o Inputs: transactionType, transactionValueCr, serviceMarkupPct, alrPercentile, hasInternalCup, hasExternalCup
`verify_tax_research_note`	Deterministically verify a piece of tax analysis (yours or anyone's): every citation is resolved against the compiled corpus, quotes and thresholds are checked against compiled law, temporal claims against validity windows — INCLUDING claim Inputs: text, as_of
