[Bug]: Inconsistent MCP tool availability with Ollama custom provider (tools discovered but not consistently available during chat)

[toddwmurray]

Bug Description

Bug Description
Environment
Hermes Agent: 0.19.0
OS: Ubuntu 24.04
Provider: custom
Endpoint: http://localhost:11434/v1
Model: qwen3:14b (Ollama)
Home Assistant MCP

Configuration is valid.

hermes mcp test homeassistant

passes successfully.

hermes tools list

shows:

Built-in toolsets:
...
homeassistant enabled

MCP servers:
homeassistant all tools enabled

The Hermes startup log reports:

MCP server 'homeassistant' (HTTP): registered 25 tool(s)

including tools such as

mcp__homeassistant__GetDateTime
mcp__homeassistant__GetLiveContext
HassTurnOn
...
Problem

The LLM never receives the MCP tools.

Example prompt:

Call the tool mcp__homeassistant__GetDateTime.
Do not use the terminal.

The model reasons:

Looking at the list of functions provided, I don't see a tool named mcp__homeassistant__GetDateTime.

It then replies:

The tool mcp__homeassistant__GetDateTime is not available in the provided list of functions.

Likewise, asking:

what time is it

causes the model to say:

Looking at the list of tools provided...

and it only sees:

terminal
browser
web search
weather

It never mentions any MCP functions and executes:

date

through the terminal instead.

Expected behavior

The registered MCP tools should be included in the tool/function list sent to the model so the model can invoke them.

Actual behavior

Hermes registers the MCP server successfully but the model reports that the MCP functions are not present in the available function list.

Steps to Reproduce

1. hermes
2. Call the tool mcp__homeassistant__GetDateTime. Do not use the terminal.

Expected Behavior

local time on HA.

Actual Behavior

From hermes, I want to query Home Assistant, but it's not working.

Inconsistent MCP tool availability

With no configuration changes, the same installation produces different model behavior:

hermes mcp test homeassistant consistently discovers 21 tools, including GetDateTime and GetLiveContext.
During chat, the model alternately reports:
the tool does not exist,
the tool exists but has unexpected required parameters (entity_id, attribute),
or that no Home Assistant integration tools are available.

This suggests the runtime tool list presented to the model is inconsistent with the tools discovered by the MCP subsystem.

Affected Component

Other, CLI (interactive chat)

Messaging Platform (if gateway-related)

No response

Root Cause

The Home Assistant MCP server was configured correctly and hermes mcp test homeassistant successfully discovered all Home Assistant tools. However, the built-in Home Assistant toolset remained unavailable because the availability check only tested for the HASS_TOKEN environment variable.

The Home Assistant MCP configuration used MCP_HOMEASSISTANT_API_KEY, so _check_ha_available() returned False, preventing the built-in Home Assistant tools from being registered.

Resolution

Loaded the Hermes .env file into the shell before starting Hermes and exported the expected Home Assistant environment variables:

set -a
source ~/.hermes/.env
set +a

export HASS_TOKEN="$MCP_HOMEASSISTANT_API_KEY"
export HASS_URL="http://192.168.1.92:8123"

After restarting Hermes:

Home Assistant tools were registered successfully.
ha_list_entities returned Home Assistant entities.
ha_get_state successfully queried individual entities.
ha_call_service successfully controlled Home Assistant devices (verified by turning a floodlight on).
Remaining Observation

The integration is functioning correctly. The remaining limitation is discoverability rather than connectivity: ha_get_state works when given an entity ID, but natural-language discovery of specific entities among hundreds of Home Assistant entities would benefit from an additional search tool (for example, ha_search_entities(query)).

I would not state that this is a Hermes bug, because we can't prove that from the evidence. The issue may simply be that the built-in Home Assistant tool expects HASS_TOKEN, while the MCP configuration uses MCP_HOMEASSISTANT_API_KEY. It's better to report exactly what you observed and how you resolved it.
