Supported methods are: create, update, delete\"); the other method-dispatch tools don't, so the behavior is inconsistent.\n\nSeparately, `pull_request_review_write` decodes arguments with `mapstructure.WeakDecode` (it does not use RequiredParam like the other tools), so omitting the required method produces \"unknown method: \"  with an empty value — instead of telling the caller that method is required.\n\nAffected tools: `pull_request_read`, `pull_request_review_write`, `issue_read`, sub-issue write, actions (list/get/run), projects (list/get/write), ui_get.\n\n### Affected version\n\nVersion: v1.3.0\nCommit: 34227037fc48771baea9af7163e28cb6556ef287\nBuild Date: 2026-06-11T14:16:55Z\n\n### Steps to reproduce the behavior\n\n1. Call `pull_request_review_write` with the required method omitted, e.g. `{ \"owner\": \"o\", \"repo\": \"r\", \"pullNumber\": 42 }`.\n2. View the output.\n3. Server returns (tool-result error, HTTP 200 `isError`): \n\n`unknown method: `\n(empty after the colon — method was never supplied, but the error doesn't say it's required or what the valid values are).\n\nOr, with an unrecognized value `{ \"method\": \"bogus\", ... }`:\n\n`unknown method: bogus`\nNo list of supported methods. The same bare error occurs on pull_request_read, issue_read, actions_*, projects_*, and ui_get for any unrecognized method.\n\n### Expected vs actual behavior\n\nExpected: the error names the supported methods (matching labels.go, e.g. unknown method: bogus. Supported methods are: create, submit_pending, delete_pending, resolve_thread, unresolve_thread), and an omitted required method reports method is required. Supported methods are: ....\n\nActual: a bare unknown method: \u003cvalue\u003e with no guidance; for pull_request_review_write an omitted method yields unknown method:  (empty), which reads like a routing bug rather than a missing required argument.\n\nLogs\nTool-result error text returned by the server:\n\nunknown method:\nunknown method: bogus","author":{"url":"https://github.com/gustavo-sec","@type":"Person","name":"gustavo-sec"},"datePublished":"2026-06-17T02:11:33.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/2712/github-mcp-server/issues/2712"}
