IDA Fast MCP demonstrates strong naming conventions and clear intent across all 18 tools. All tools have descriptions and explicit input schemas with typed parameters. Tool names follow verb_noun patterns (list_*, get_*, set_*) and are highly specific. Descriptions are adequate but many fall short of the 50-200 char LLM-optimized range established in production baselines. Several parameter descriptions lack format/constraint guidance. Output schemas are not explicitly documented in the code, only implied by implementation. Error handling is minimal; no guidance on recovery strategies or classification (retryable vs fatal). No tool annotations (readOnlyHint/destructiveHint/idempotentHint) despite clear risk profiles (READ_ONLY, WRITE, DESTRUCTIVE). Security model is robust (loopback-only default, Host header validation, no secrets in params), but no per-tool scope declarations.

• Add tool annotations to all tools: readOnlyHint: true for all list_*/get_* tools; destructiveHint: true for set_*/run_python; idempotentHint: true for read-only operations. This enables agents to plan more safely and understand blast radius.
• Expand parameter descriptions for polymorphic inputs (e.g., 'address' parameter): 'Address as hex string (e.g., 0x401000) or symbol name (e.g., main). Symbol names are resolved to their address in the current database.'
• Document output schemas inline in tool descriptions or as a separate schema field. Example: 'Returns list of {address: hex string, size: int, name: string}' or formalize as JSON Schema.
• Enhance error messages with recovery guidance. Instead of returning a bare error, include: 'Symbol not found: main. Available functions: [list of top 5]. Call list_functions() with a substring to search.'
• Expand tool descriptions to 100-150 chars and include WHEN to use the tool. Example for get_bytes: 'Read up to N bytes from a given address or symbol name. Use this to inspect memory contents, extract shellcode, or verify byte patterns. Address can be hex (0x401000) or a symbol name (malloc).'
• Add dry-run parameter to run_python: code_only (bool, default true) to preview what code will execute without committing side effects. This prevents accidental database modifications.
• Document per-tool permission requirements in descriptions. Example: 'Requires write permission on the IDA database. Modifies symbol tables and is irreversible.'
• Add pagination/limit guidance to all list_* tools. Specify that results are capped at limit (e.g., 'Limited to 30 results; call list_functions(query=..., limit=...) again with an offset if needed.').
