Searching for free tiers is the obvious half. The half worth connecting is the change history: check_vendor_risk grades a vendor on what it has actually done to its pricing, and get_deal_changes lists the removals and reductions behind the grade. Put next to a stack recommendation, a cost estimate at a chosen scale and an audit of what you already run, it answers the question before the commitment rather than after the invoice.
An index of developer-infrastructure offers — free tiers, credits and discounts — searchable by keyword, category and eligibility, with tools that track how vendors have changed their pricing, compare two of them, and audit a stack you already run.
- list_categories browses the categories — databases, cloud hosting, CI/CD, monitoring, auth, search and more — and search_offers finds offers by keyword, category or eligibility type, sorted and paginated
- get_offer_details returns one vendor's full free-tier or deal terms, and can bring up to five comparable vendors in the same category back alongside it
- compare_services puts two vendors side by side on free-tier limits, pricing tiers, key differences and their recent deal changes
- get_deal_changes tracks what vendors actually did — removals, limit reductions, limit increases, new free tiers and restorations — filtered by vendor or change type since a date you choose
- check_vendor_risk answers whether a free tier is safe to build on, returning stable, caution or risky along with the pricing-change history behind that verdict
- get_stack_recommendation takes a description of what you are building and returns a whole free-tier stack, instead of making you search category by category
- estimate_costs prices the vendors you already use at a given scale, and audit_stack reviews a current stack per service for savings, pricing risk and missing capabilities
- get_expiring_deals surfaces credits and tiers with a deadline approaching, while get_new_offers, get_newest_deals and get_weekly_digest cover what has changed recently
No credentials and nothing to configure. Run it locally over stdio with npx agentdeals, or point a client at the hosted Streamable HTTP endpoint at https://agentdeals.dev/mcp. It also installs as a Claude Code plugin or as a .mcpb bundle for Claude Desktop, and the same index is reachable over a REST API for use outside MCP.
One command — npx -y agentdeals
