What is kiro-web-search AGENTS.md?

Project-specific instructions for Kiro Web Search, a small server that connects coding agents to Kiro's web-search service. It explains the project structure, architecture, configuration, and conventions.

It is for guiding work on the Python MCP server, its plugin files, authentication setup, and related documentation.

It gives coding agents the context needed to change this repository without misunderstanding how its adapter works.

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	$0.01017	$0.01017
Opus 5.5	$0.00407	$0.00407
Sonnet 5.5	$0.00203	$0.00203
Haiku 4.5	$0.00102	$0.00102

Security

Grade A, and why

kiro-web-search AGENTS.md 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

AGENTS.md

Agent-facing entry point. For user-facing info see README.md.

What this project is

A single-tool MCP server that wraps Kiro's backend web_search endpoint. The upstream is itself an MCP server reachable via AmazonCodeWhispererStreamingService.InvokeMCP on runtime.us-east-1.kiro.dev, so this project is fundamentally a transport adapter: stdio JSON-RPC ↔ HTTPS + Bearer auth.

Keep it thin. Any temptation to "enrich" or "post-process" results should be resisted — see docs/design-docs/features/web-search-mcp.md for the reasoning.

Architecture one-liner

Code map

src/kiro_web_search/server.py — everything lives here: config resolution, HTTP call to upstream, FastMCP tool definition, CLI entry point.
src/kiro_web_search/__main__.py — enables python -m kiro_web_search.
.claude-plugin/marketplace.json — makes this repo a Claude Code plugin marketplace. Users add via /plugin marketplace add vokako/kiro-web-search.
.claude-plugin/plugin.json — plugin manifest. Declares userConfig.api_key (prompted at install time, stored in the system keychain) and embeds the MCP server config inline. Substitution: KIRO_API_KEY=${user_config.api_key}.
.agents/plugins/marketplace.json — Codex plugin marketplace. Users add via codex plugin marketplace add vokako/kiro-web-search. Local plugin source must be a subdir (./plugins/...); Codex rejects "./", so the Codex plugin cannot live at the repo root like the Claude one does.
plugins/kiro-web-search/.codex-plugin/plugin.json — Codex plugin manifest. Unlike Claude, mcpServers is a path to a file, not an inline object, and there is no userConfig secret prompt.
plugins/kiro-web-search/.mcp.json — Codex MCP server file. The API key is inherited from the shell via env_vars: ["KIRO_API_KEY"] (Codex can't prompt for it). Format verified against openai/codex core-plugins/src/loader.rs.
tests/ — smoke tests for the handshake + a mocked tools/call.

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.
