Production-ready multi-project MCP server for coding agents
Strong foundation with 33 well-named tools, comprehensive schemas, and consistent descriptions. All tools have input schemas with typed parameters and descriptions. Tool names follow verb_noun convention (run_build, git_status, list_directory). Descriptions average ~80 chars, meeting baseline. However, parameter descriptions are often minimal (10-30 chars), lacking context on constraints, formats, and when to use each tool. Output schemas are not documented in visible code. Error handling guidance is absent, tools return raw errors without recovery hints. No tool annotations (readOnlyHint, destructiveHint) despite clear risk classifications. Missing idempotency guarantees for git operations and file writes.
Apply unified diff or structured edits
Create file safely
Delete file or directory
Get project metadata by project_id
Get normalized project tree
Stage files with git add
List git branches for a project
Parameter descriptions are minimal (10-30 chars) and lack actionable constraints. E.g., 'Project identifier' does not explain format, length, or how to obtain one. LLMs cannot infer valid values.
Output schemas are not documented in visible code. Tools return structured objects (exit_code, stdout, stderr, etc.) but LLMs cannot see the schema to plan downstream calls or extract fields reliably.
No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear risk classifications (READ_ONLY, WRITE, DESTRUCTIVE, REVERSIBLE). LLMs cannot reason about safety or retry semantics.

Error handling lacks recovery guidance. Tools throw ValidationError and SecurityError but responses do not suggest next steps (e.g., 'Try search_users() first' or 'Use allowlisted commands only'). Agents cannot self-correct.
Git operations (git_commit, git_push, git_add) lack idempotency guarantees. Agents retrying on transient failures risk duplicate commits or pushes. No dry-run or confirmation pattern for irreversible operations.
