Coala Client
Part of the coala ecosystem. CLI for chat with OpenAI-compatible LLMs (OpenAI, Gemini, Ollama) and MCP (Model Context Protocol) servers. Supports importing CWL toolsets as MCP servers, importing skills.
Config paths
- MCP config and toolsets:
~/.config/coala/mcps/
- mcp_servers.json — server definitions - <toolset>/ — per-toolset dirs with run_mcp.py and CWL files
- Skills:
~/.config/coala/skills/(one subfolder per imported source) - Env:
~/.config/coala/env(optional; key=value for providers and MCP env)
Quick start
- Init (first time)
coala init — creates ~/.config/coala/mcps/mcp_servers.json and env.
- Set API key
e.g. export OPENAI_API_KEY=... or export GEMINI_API_KEY=.... Ollama needs no key.
- Chat
coala or coala chat — interactive chat with MCP tools. coala ask "question" — single prompt with MCP.
- Options
-p, --provider (openai|gemini|ollama|custom), -m, --model, --no-mcp.
MCP: CWL toolsets
No API key needed for MCP import, list, or call — only for chat/ask with an LLM.
- Import (creates toolset under
~/.config/coala/mcps/<TOOLSET>/and registers server):
coala mcp-import <TOOLSET> <SOURCES...> or alias coala mcp ... SOURCES: local .cwl files, a .zip, or http(s) URLs to a .cwl or .zip. Requires the coala package where the MCP server runs (for run_mcp.py).
- List
coala mcp-list — list server names. coala mcp-list <SERVER_NAME> — print each tool’s schema (name, description, inputSchema).
- Call
coala mcp-call <SERVER>.<TOOL> --args '<JSON>' Example: coala mcp-call gene-variant.ncbi_datasets_gene --args '{"data": [{"gene": "TP53", "taxon": "human"}]}'
Skills
- Import (into
~/.config/coala/skills/, one subfolder per source):
coala skill <SOURCES...> SOURCES: GitHub tree URL (e.g. https://github.com/owner/repo/tree/main/skills), zip URL, or local zip/dir.
- In chat
/skill — list installed skills. /skill <name> — load skill from ~/.config/coala/skills/<name>/ (e.g. SKILL.md) into context.
Chat commands
/help,/exit,/quit,/clear/tools— list MCP tools/servers— list connected MCP servers/skill— list skills;/skill <name>— load a skill/model— show model info/switch <provider>— switch provider
MCP on/off
- All off:
coala --no-mcp(orcoala ask "..." --no-mcp). - One server off: remove its entry from
~/.config/coala/mcps/mcp_servers.json. - On: default when
--no-mcpis not used; add or restore servers inmcp_servers.json.
Providers and env
Set provider via -p or env PROVIDER. Set keys and URLs per provider (e.g. OPENAI_API_KEY, GEMINI_API_KEY, OLLAMA_BASE_URL). Optional: put vars in ~/.config/coala/env. coala config — print current config paths and provider/model info.
