It keeps input schemas intact, validates calls before the upstream is invoked, and can recover an oversized result exactly without repeating that invocation. Choose a mode Mode What the host sees Best fit ------- ------------------------------------------------------------------------------------------------------------------ ---------------------------------------------------------------- Native Authorized original tool names and full schemas, plus read result Hosts that work well with a normal MCP catalog, including Codex Compact find tool , call tool , and read result ; discovery returns each match's full original schema A small, predictable host surface Extreme The Compact tool surface and schemas; only sufficiently large results receive a shorter recoverable first delivery Context-sensitive hosts where a smaller first result is valuable Compact is the default for start . Native is the default installation plan for Codex. Compact is the default for Claude Code; Claude Code supports Compact and Extreme installation plans, not Native. All modes apply the same allow/deny authorization. Compact and Extreme return at most three discovery matches, each with the original required fields, enums, and nested schema. A call is validated against that original schema before the upstream server is contacted. find tool rejects unknown fields and queries longer than 256 Unicode code points l","default_branch":null,"files":null,"tree":[],"storefront":"/r/lennney","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/lennney/mcp-slim-guard/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
