Tool Namespace Resolver and Fuzzy Matcher MCP Connector for Claude

Resolves tool name hallucinations and misspellings using hierarchical matching logic.

3 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides advanced tool resolution capabilities to prevent LLM hallucinations. It uses a strict hierarchy of matching: Exact Match, Case-Insensitive Match, Namespace Match, and finally Fuzzy Matching via Levenshtein distance. It is designed to fix 'tool not found' errors in frameworks like LangChain and CrewAI by mapping misspelled or partial names to valid identifiers. Use resolve_tool_name for single queries, get_matching_tools_bulk for batch processing, or validate_tool_namespace to verify functional groups.

Resolve the tool name 'pythn' from the list ['code_execution_python', 'search_web']

The tool name 'pythn' has been resolved to 'code_execution_python' with a fuzzy match.

Check if 'search' belongs to the 'web_' namespace in ['web_search', 'web_map', 'file_read']

Yes, 'search' matches the 'web_' namespace, which contains 2 tools.

Find all matches for ['search_web', 'pythn'] in ['search_web', 'code_execution_python']

Matches found: 'search_web' (exact) and 'code_execution_python' (fuzzy).

The engine follows a strict priority: it first looks for an exact match, then a case-insensitive match, then a namespace match, and finally a fuzzy match using Levenshtein distance. Once a higher-priority match is found, the search stops.
