fix(fetch): handle malformed input without crashing Changes `raise_exceptions=True` to `raise_exceptions=False` in the fetch server's `Server.run()` call, preventing the server from crashing on malformed JSON-RPC input. This aligns with the SDK's intended default behavior and is consistent with other reference servers. Fixes #3359
feat(sequential-thinking): add tool annotations Adds MCP ToolAnnotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to the sequential-thinking tool, bringing it in line with the annotation pattern established by the filesystem server. Fixes #3403
…te_branch, git_log, and git_branch (#3545) fix(git): add missing argument injection guards Extends existing startswith("-") input validation to git_show, git_create_branch, git_log, and git_branch, preventing user-supplied values from being interpreted as CLI flags by GitPython's subprocess calls to git.
feat(git): add tool annotations Adds MCP ToolAnnotations to all 12 git server tools, marking read-only operations (status, diff, log, show, branch) and distinguishing destructive (reset) from non-destructive write operations (add, commit, create_branch, checkout). Fixes #3573
…3533) fix(sequential-thinking): use z.coerce for number and safe preprocess for boolean params Uses z.coerce.number() for number fields and a z.preprocess() helper for boolean fields to handle string-typed parameters from LLM clients. The preprocess approach correctly handles "false" → false, avoiding the z.coerce.boolean() footgun where Boolean("false") === true. Fixes #3428
