hermes - 💡(How to fix) Fix feat(openviking): Add missing tools — grep, glob, forget, health [1 comments, 2 participants]

Feature Request: Align OpenViking plugin tools with OpenViking MCP v0.3.16 Context The OpenViking memory server (v0.3.16) now exposes 10 tools via its native MCP endpoint:

Current State The Hermes OpenViking plugin (plugins/memory/openviking/init.py) currently exposes 5 tools:

viking_search (covers both find and search) viking_read viking_browse (covers list) viking_remember viking_add_resource Missing Tools The following tools are not exposed by the Hermes plugin:

viking_grep — Search content using regex patterns. Useful for exact text matching across memories. viking_glob — Find files matching glob patterns (e.g., **/*.md). Useful for filename-based discovery. viking_forget — Delete a viking:// URI. Currently agents have no way to clean up obsolete memories. viking_health — Check server health. Useful for agents to self-diagnose connectivity issues. Impact Agents running Hermes with OpenViking cannot:

Delete stale or incorrect memories (no forget) Search for files by pattern (no grep/glob) Self-diagnose connectivity issues (no health) This creates a growing divergence between the MCP-native experience and the Hermes plugin experience as OpenViking evolves.

Suggested Implementation The OpenViking REST API endpoints already exist for all 4 missing tools:

POST /api/v1/search/grep (or equivalent) GET /api/v1/fs/glob DELETE /api/v1/fs GET /health Adding these as tool schemas + handlers in init.py would be straightforward, following the existing pattern of SEARCH_SCHEMA / _tool_search.
