| compress_tool_definitions | Shrink MCP tool descriptions and JSON schemas to cut context cost without changing how agents call them. Returns the compressed definitions plus exact token savings. |

| compare_automation_platform_costs | Compare real monthly cost on Zapier (per task) versus Make (per operation) for the same workflow volume, including the counting-model difference that makes the two quotes non-obvious. |
| detect_polling_cost_traps | Find the most common hidden cost in no-code automation: using polling where a webhook would do. Quantifies the wasted task/operation quota and the monthly dollars. |
| estimate_selfhosted_tco | Compare paying hosted CI overage against running self-hosted runners, including the maintenance hours people forget to cost. Reports the true break-even volume. |
| compare_ai_coding_tool_costs | Compare monthly and annual cost of AI coding subscriptions (GitHub Copilot, Cursor, Claude Code/Pro/Max, OpenAI Codex) for a given team size and usage intensity, then compare the winner against pay-as-you-go API pricing for the same workload. Prices verified 2026-09. |
| compare_llm_api_costs | Rank 18 LLM models by the real monthly cost of a given workload (input/output tokens per call × calls per month). Reports the cheapest and most expensive option, the cost spread, and which models can actually hold your prompt in their context window. |
| plan_context_window_budget | Given a set of MCP servers and their tool counts, show for every model context window (128K, 200K, 1M, 10M) how much of the window the tool definitions consume, how much is left for conversation, and whether the server set fits at all. Answers "how many servers can I attach on model X?". |
