A setup guide for connecting Gecko's hosted MCP service to an agent client and checking it with a real read-only call. MCP is a standard way for an agent to use external tools.

Use it when installing Gecko in Claude, Cursor, VS Code, or another client that supports MCP configuration.

It avoids configuration mistakes by using Gecko's canonical client settings and verifies that the connection actually works.

gecko-setup — Skill for Claude Code by GeckoVision

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add GeckoVision/gecko-surf --skill gecko-setup

Clone the repo

git clone --depth 1 https://github.com/GeckoVision/gecko-surf

Made for: Claude Code.

Or install gecko-surf, the plugin that ships this one along with the rest of its 6 skills, 2 commands, 2 agents.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00071	$0.00619
Opus 5	$0.00036	$0.00309
Sonnet 5	$0.00014	$0.00124
Haiku 4.5	$0.00007	$0.00062

Security

Grade A, and why

gecko-setup 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 6d 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.

What it actually says

gecko-setup — install the hosted Gecko surface and prove it works

Your goal: wire the hosted MCP surface into the client you are running in and verify with one real call. Gecko turns APIs and Solana programs into first-call-correct tools; it never holds a key and never signs.

Step 1: Fetch the canonical config

One file carries every client's exact wiring — always start from it rather than hand-typing URLs:

curl -s https://geckovision.tech/mcp-config.json

Step 2: Install for THIS client

Claude Code:

claude mcp add --transport http gecko https://mcp.geckovision.tech/orquestra/mcp

Claude web / desktop: Settings -> Connectors -> Add custom connector with the clients.claude_web.connector_url from the config (the web UI takes only the URL — no JSON there).
Cursor: merge clients.cursor.json into ~/.cursor/mcp.json.
VS Code: merge clients.vscode.json into .vscode/mcp.json.
Anything else that reads mcp.json: clients.generic_mcp_json.

No account and no API key for the open surfaces. Gated surfaces answer 401 with a self-serve mint path — https://geckovision.tech/auth.md.

Step 3: Verify with a real call

List the new server's tools, then make one read-only call: list_stores (browses real Solana storefronts, free) or search_capabilities with a question. Setup is DONE when that call answers — a config edit alone is not done.

Step 4 (optional): local comprehension of the user's own API

npx @geckovision/gecko add https://api.example.com/openapi.json

or the Claude Code plugin: /plugin marketplace add GeckoVision/gecko-surf.

Refusals you may meet, and what they mean

Gecko refuses loudly instead of failing silently. signer-required means a money path needs a wallet (the refusal carries the signer runbook — follow it). store-unknown means absence, never a fallback to another store. Every refusal names its next step; read it before improvising.

Changes

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.
