# NousResearch/hermes-agent · MCP tool name normalization and dispatch failures

## Open now

- Nothing open on GitHub.

These issues and fixes center on tool dispatch failures caused by naming mismatches—including stripped or added \`mcp_\` prefixes, CamelCase/PascalCase drift, and \`_tool\` suffix variations—between how tools are registered and how Anthropic/Claude models emit tool names. Several fixes address normalization at dispatch, registry, and OAuth round-trip layers.

## TL;DR
