Install

pipx install meshapi-code           # recommended
uv tool install meshapi-code        # if you use uv
pip install meshapi-code            # plain pip

PyPI package is meshapi-code; the command on your $PATH is meshapi (same split Claude Code uses: @anthropic-ai/claude-code → claude).

What it does

• Streaming completions with live markdown rendering (rich).
• Real cost per turn — Mesh returns cost in the SSE tail; we surface it after every reply and accumulate session $….
• Tool calling — the model can read files, write files, and run shell commands in the launch directory. Off by default behind an approval prompt; toggle with one key.
• Permission modes — approve each (default), bypass perms (auto-execute, for trusted prompts), or no access (chat only). Cycle live with Shift+Tab.
• Mid-session switching — /model openai/gpt-4o-mini, /route cheapest, /mode bypass.
• Smart routing — /route cheapest|fastest|balanced hands model selection to Mesh's gateway, so you don't have to.
• Persistent input history — up-arrow recalls past prompts across sessions.
• Config + env-var override — ~/.meshapi/config.json, MESHAPI_API_KEY.

Tool calling

When tools are enabled, the model can call:

Tool	What it does
read_file	Read a file from the working directory (or absolute path).
write_file	Create or overwrite a file. Parent dirs are created.
run_bash	Run a shell command in the working directory. 60s timeout, 8000-char output cap.

The launch CWD is baked into the system prompt, so relative paths the model produces resolve where you'd expect. Three permission modes, cycled live with Shift+Tab or set with --mode / /mode:

• ask (default) — every tool call requires a y/n confirmation. Safe.
• bypass — the model auto-executes. Fast, like Claude Code's --dangerously-skip-permissions. Use only when you trust the prompt.
• none — tools aren't sent to the model at all. Pure chat.

meshapi --mode bypass     # start in auto-execute mode
meshapi                   # default ask; press Shift+Tab to cycle

Slash commands

Command	What it does
/help	List commands
/model <name>	Switch model (e.g. anthropic/claude-sonnet-4.5, openai/gpt-4o-mini)
/route <mode>	cheapest, fastest, balanced, or default
/mode <perm>	ask, bypass, or none (Shift+Tab also cycles)
/file <path>	Inject a file into the conversation
/system <text>	Replace system prompt and reset chat
/cost	Show cumulative session spend
/clear	Reset conversation
/exit	Quit

Config

~/.meshapi/config.json:

{
  "base_url": "https://api.meshapi.ai/v1",
  "model": "anthropic/claude-sonnet-4.5",
  "system": "You are a helpful coding assistant. Be concise.",
  "route": null
}

The API key is read from MESHAPI_API_KEY (preferred) or stored in the same file. Input history lives at ~/.meshapi/history.

About Mesh API

Mesh API is a unified LLM gateway: one API key, 300+ models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, Alibaba, and more. It's OpenAI-compatible — change the model name in your request, leave everything else alone.

• Zero platform fees for 12 months. You only pay for tokens.
• Smart auto routing. route: cheapest|fastest|balanced and the gateway picks for you.
• Automatic failover. If a provider goes down, your request routes to another. Your users won't know.
• Highest rate limits. Capacity is pooled across providers, so you hit ceilings later than going direct.
• Zero data retention. Prompts and completions pass through; we don't store them.
• Multi-currency billing. USD and INR (for India-based teams) at launch.
• Ready-made workflows. Pre-built prompt templates you can plug into any model.
• Full observability. Every request, token, cost, error, and model usage tracked in real time. Per-key spending limits and usage controls.

Built by the founders of TagMango (YC W20) and AI Fiesta (1M+ users across India). We got tired of managing five different provider dashboards ourselves, so we built this.

Why this CLI exists

Any generic OpenAI-compatible chat CLI talks to Mesh. meshapi adds three things a generic CLI can't: (1) the gateway-only cost field shown after every turn, (2) /route controls that drive Mesh's gateway-side model selection, and (3) tool calling that resolves paths against the directory you launched from.

Roadmap

• ✅ v0.3 — tool calling, ask/bypass/none permission modes, CWD-aware system prompt
• v0.4 — repo-aware mode, diff apply, /cd to change working dir mid-session
• v0.5 — npm i -g meshapi-code (Node port using ink + chalk), Homebrew tap, curl|sh installer at meshapi.ai/install.sh
