• Whether its tools do the product's job has not been judged yet.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• search_discoveries

  Find human-reviewed research notes about new products, replacement workflows, changed flows and build-versus-buy lessons. Returns original posts and primary sources with explicit author-reported versus documented claims and unknown costs…

• search_recipes

  Use when the user wants a cheaper way to do a job and names a feature or kind of tool rather than one product: 'cheaper keyword research', 'forms without Typeform', 'what can replace our CRM'. Filter by the vendor they pay for, a feature…

• get_recipe

  Full detail for one recipe from search_recipes: every replacement path with modeled first-year savings, monthly cost, setup time and upkeep, what is out of scope, checks to run before switching, how to leave the current vendor (cancel…

• find_alternatives

  Use when the user names one product they pay for and asks for something cheaper, whether it's worth it, or what to switch to: 'cheaper than Typeform?', 'is Semrush worth $139 a month for us?', 'we pay $90 for SendGrid'. Pass what they pay…

• get_build_packet

  Use when the user wants to replace a tool by building their own (Replace with AI): returns SPEC.md, AGENTS.md and the runbook files a coding agent builds from, for a recipe with a build path. A recipe without one returns the assessment…

• search_workflow_recipes

  Use for a whole operational change rather than one subscription: billing shared across projects, moving hosting or email, retiring a dormant project, cheaper AI model routing, queues, auth or storage. Returns reviewed runbooks with the…

• get_workflow_recipe

  One runbook from search_workflow_recipes in full: the evidence to collect, keep/downsize/consolidate/migrate/build/retire decisions, ordered steps, acceptance tests, rollout, rollback, maintenance, costs still unresolved, and scoped…

• leaderboard

  The top replacement paths across the catalog by modeled first-year savings, payback months, or how often people and agents used them. Leaves out partial replacements unless include_partial, and never lists trials, one-time credits…

• audit_stack

  Use when the user wants their stack checked as a whole: several subscriptions, the paid services in a codebase, or a portfolio of products ('audit what we pay for', 'what can we cut?'). One line per service with vendor, plan, what they…

• get_detection_rules

  Rules for finding paid services in a codebase on the user's own machine: package names, environment variable name patterns, config files, API hosts and feature patterns for about 100 vendors. Apply them locally and send only the vendor…

• get_usage_questions

  Before an audit: which usage numbers decide each vendor's answer (emails a month, domains, database size, seats…), where the user finds each one (dashboard page, API, export), and ready-to-ask questions. Units already stated in context…

• start_audit

  Start here when the user wants to cut spend across several tools, consolidate apps, or replace one tool safely, and the bills alone won't decide it. Send vendors and team_size (or a stack manifest) and get the few missing facts that would…

• list_categories

  The catalog's categories with how many recipes each has and the best modeled first-year saving in each. Stackcut stores the arguments of tool calls to improve its recommendations (vendor names, prices, seats, features, usage numbers…

• get_my_plan

  Use only when the user gives you a Stackcut agent code (it starts with sca_; they copy it from 'Send to my agent' on stackcut.io). Returns their own savings plan: every subscription with its verdict, the proven saving, the proof…

• choose_stack

  Use when the user is picking vendors for something they're building: 'cheapest database for 20k users', 'Resend or Postmark at 60,000 emails a month?', 'what will auth cost at 10k MAU?'. Give each job with its volumes and must-have…

• plan_stack_from_spec

  Use when the user shares a product brief or spec and asks what to build it with or what it will cost. Works out the jobs the brief needs (what it rules out, plans for later or already has is never priced), the volumes from its numbers or…

• list_stack_jobs

  The jobs choose_stack can compare (database, auth, hosting, transactional and inbound email, object storage, LLM APIs, payments, sandboxes, browser automation, queues…) with how many vendors each has, plus the volume units and aliases it…

• get_exit_plan

  Use when the user wants to cancel, unsubscribe from, pause or pay less for something they subscribe to: streaming, music, news, dating, cloud storage, AI tools, apps or business software ('cancel YouTube TV', 'how do I get out of Adobe'…

• prepare_negotiation

  Find documented existing-customer offers, cancellation-flow promotions and renewal negotiation routes for a service. Returns channel- and market-specific paths, vendor sources, freshness, questions and draft…

• search_exits

  Lists services in Stackcut's cancel library (streaming, music, news, dating, cloud storage, AI tools, apps and software), by name, domain or category, with the page and JSON for each. Use get_exit_plan for one service's steps. Stackcut…

• report_exit_outcome

  After the user reports what happened, count a cancellation, keeping the service for less, getting blocked, or changed steps. This updates only an anonymous usage counter and does not verify an action. Use report_action_outcome for a…

• report_action_outcome

  Record a minimal structured report about an attempted cancel, price reduction, negotiation, pause, downgrade, or switch. First call get_exit_plan and send its packet_revision and route_id; stale packet revisions are rejected. Reports are…

• report_guide_feedback

  After using guidance, report a missing vendor or billing route, a mismatching step, unavailable source, incomplete instructions, unexpected fee, observed retention offer, required human handoff, or that the guide matched. Send only the…

• report_outcome

  Only after the user confirms what they did: record that they picked, switched to or reverted from a replacement path. Adds one to anonymous public counters and stores no personal data. Stackcut stores the arguments of tool calls to…
