LLM-based Chat Assistant

LLM-based Chat Assistant

Experimental LLM-based chat assistant bot available in the OSGeo Matrix space.

The bot connects Matrix chat to an LLM agent and local MCP tools for OSGeo-specific search, wiki lookup, document search, and web/time/weather utilities.

Access

The bot is available in the Matrix room:

#lounge:osgeo.org
#library:osgeo.org

Matrix identifier:

@llm-assitant:matrix.org

The bot responds when mentioned, or when a line starts with:

!oc
bot

Example:

!oc search the OSGeo wiki for board elections
bot what is GeoNode?
@llm-assitant:matrix.org find OSGeo documents about map projections

Usage notes

The assistant is experimental. It may make mistakes, especially for operational or infrastructure-critical questions. Verify important answers before acting on them.

Do not send secrets, passwords, API keys, private tokens, or sensitive credentials to the bot.

Tool calls may be visible in chat logs. This is normal. Example:

> query=spam, limit=10 [osgeo-knowledge_search_content]
> query=spam, limit=10 [osgeo-knowledge_search_wiki]

The prefix identifies the MCP server, and the suffix identifies the tool.
