add-ollama-tool

add-ollama-tool is a skill for Claude Code from sliamh11/Deus. It costs 34 tokens per session (1,103 once invoked), scanned A, a copy of add-ollama-tool, MIT.

An integration that adds Ollama, a tool for running AI models locally, to the container agent through MCP, a standard way for software tools to communicate with an agent.

In plain words
What is it for?
Listing installed Ollama models and asking a selected local model to summarize, translate, answer general questions, or help with code.
Why use it?
It lets the agent send suitable tasks to local models instead of always using remote models, which can reduce cost and waiting time.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./container/build.sh.

Good fit Listing installed Ollama models and asking a selected local model to summarize, translate, answer general questions, or help with code.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-ollama-tool scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Add Ollama Integration

This skill adds a stdio-based MCP server that exposes local Ollama models as tools for the container agent. Claude remains the orchestrator but can offload work to local models.

Tools added:

  • ollama_list_models — lists installed Ollama models
  • ollama_generate — sends a prompt to a specified model and returns the response

Phase 1: Pre-flight

Check if already applied

Check if container/agent-runner/src/ollama-mcp-stdio.ts exists. If it does, skip to Phase 3 (Configure).

Check prerequisites

Verify Ollama is installed and running on the host:

ollama list

If Ollama is not installed, direct the user to https://ollama.com/download.

If no models are installed, suggest pulling one:

You need at least one model. I recommend:

ollama pull gemma3:1b    # Small, fast (1GB)
ollama pull llama3.2     # Good general purpose (2GB)
ollama pull qwen3-coder:30b  # Best for code tasks (18GB)

Phase 2: Apply Code Changes

Check if the Ollama MCP server files are already present:

test -f container/agent-runner/src/ollama-mcp-stdio.ts && echo "Already present" || echo "Not present"

If not present, the Ollama integration needs to be implemented locally. The following files are involved:

  • container/agent-runner/src/ollama-mcp-stdio.ts (Ollama MCP server)
  • scripts/ollama-watch.sh (macOS notification watcher)
  • Ollama MCP config in container/agent-runner/src/index.ts (allowedTools + mcpServers)
  • [OLLAMA] log surfacing in src/container-runner.ts
  • OLLAMA_HOST in .env.example

If the merge reports conflicts, resolve them by reading the conflicted files and understanding the intent of both sides.

Copy to per-group agent-runner

Existing groups have a cached copy of the agent-runner source. Copy the new files:

for dir in data/sessions/*/agent-runner-src; do
  cp container/agent-runner/src/ollama-mcp-stdio.ts "$dir/"
  cp container/agent-runner/src/index.ts "$dir/"
done

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
