Lantern Works GPU Prices: daily GPU rental price comparison

Lantern Works — agent deals directory

Lantern Works publishes a curated directory of affiliate and public offers for AI agents (and humans directing them): compute and GPU rental, unblock/scrapers, email, search, hosting, and related work-stack tools. Results are ranked by customer value (price, free tier, fit), never by affiliate status.

• Browse: thelanternworks.com · About
• Agent feed (JSON, no auth): thelanternworks.com/api/v1/deals.json (same bytes as /deals.json) · mirror: gist
• GPU prices: api/v1/gpu-prices.json · Stack pricing: api/v1/stack-pricing.json
• Query CLI: python3 query_deals.py --category unblock --max-price 20 (filter contract: USAGE.md)

MCP server (v0.3.4, read-only, stdio)

Free, read-only, no API key. Package lantern-works-deals-mcp on PyPI; MCP Registry name io.github.connormatthewdouglas/lantern-works-deals. Built on the official Python MCP SDK.

Tools

Tool	What it does
search_deals	Search the deals feed by text, category, offer_type, max_price and tags; paginated summaries (limit 1-25, cursor).
compare_deals	Compare 2-5 deals by id side by side, best customer value first.
get_deal	Return the full public record for one deal id.
compare_gpu_prices	Hourly rental prices for a GPU model (e.g. H100, A100 SXM, RTX 4090) across tracked providers, cheapest first, each with source_url and checked_at. "Cheapest" means cheapest among tracked providers, not the whole market. include_history=true adds each rate's price history and recent price changes (daily snapshots).
optimize_stack	Given monthly usage (pages scraped, proxy GB, emails, search queries, GPU hours/model), pick the cheapest tracked plan per line and total the monthly cost, with the calculation, sources and alternatives; unpublished prices are reported as unknown.

Install

uvx lantern-works-deals-mcp

Claude Code:

claude mcp add lantern-works-deals -- uvx lantern-works-deals-mcp

Cursor (.cursor/mcp.json) and Cline (cline_mcp_settings.json, via MCP Servers → Configure) use the same entry:

{ "mcpServers": { "lantern-works-deals": { "command": "uvx", "args": ["lantern-works-deals-mcp"] } } }

Docker: docker build -t lantern-works-deals-mcp . && docker run -i --rm lantern-works-deals-mcp (the root Dockerfile installs the pinned PyPI release and runs the stdio server). Without uv: pip install lantern-works-deals-mcp, then use "command": "lantern-works-deals-mcp". Other clients: https://thelanternworks.com/install/ · Skill: npx skills add connormatthewdouglas/agent-work-stack-deals.

Telemetry is off by default. LANTERN_TELEMETRY=1 opts in to an anonymous daily count of tool calls: tool name, version, day and count only. No arguments, IDs or IPs are sent or stored. See PRIVACY.md.

Framework examples: LangGraph (cheapest H100), CrewAI (cheapest GPU for a described job), GPU price monitor (price-drop alerts from the history API). All examples: examples/. Some tool results include referral links (affiliate: true).

Arguments, errors, data sources and tests: mcp_server/README.md.

Feed contract, validation and deploy gate

• Schema: schema.json (JSON Schema 2020-12). deals.json carries schema_version; prices are nullable (null = unknown, 0 = free tier), with explicit currency, unit, billing_period, verified_at, updated_at.
• Stable feed: https://thelanternworks.com/api/v1/deals.json is byte-identical to /deals.json (both written by scripts/generate_seo_pages.py). The gist is a byte-identical mirror.
• Private data: commission, payout and compliance data live only in a private file outside this repo (path set by LANTERN_PRIVATE_FIELDS). The generator reads it only for local sanity checks and leak detection and fails the build if any private key or commission-like text reaches public output.
• Validation: pip install jsonschema && python3 scripts/validate_feed.py --gist --links checks schema, private-leak scan, api/v1 parity, sitemap host, old-host hardcodes, gist parity and redeem URLs (403/429/timeouts warn; 404/410/DNS/persistent 5xx fail, exit 1).
• Deploy gate: GitHub Actions runs schema validation, the test suite, a clean PyPI install check and a Docker build/stdio check; Pages deploys only after they pass, then live checks run.
• Migration test: python3 scripts/test_url_migration.py checks old GitHub Pages project URLs 301 to the new domain, key pages return 200, and the feeds match.
• Compliance gate: when the private registry (path set by LANTERN_COMPLIANCE_REGISTRY) is present, the generator publishes only deals whose status is approved; others move to a private held file and come back automatically once approved. Absent registry (CI) = feed published as-is.
• For agents: https://thelanternworks.com/for-agents/ documents endpoints, schema and offer types.
