What Codepeg is for

A hand-curated code-breaking & feedback-guessing game reference — mechanics, strategy and real combinatorics.

What it does

Codepeg is a fully local, hand-curated reference for code-breaking and feedback-based guessing games. mechanic_info explains one generic named mechanic (exact/partial match feedback, duplicate-symbol handling, minimax strategy, hard-mode constraint, daily shared puzzle, and more). game_type_list lists the core game archetypes covered — peg-and-color deduction, digit-position deduction, fixed-length word guessing, and an unordered shared-letter word duel — with their default code length, pool size and player count. optimal_strategy_tip gives five concrete tips for playing one game type well. feedback_system_explainer explains exactly how a game type's feedback works, such as exact/partial peg counts or green/yellow/gray letter tiles. combinatorics_note runs a REAL calculation of how many possible codes exist for a given code length and symbol-pool size, with and without repeated symbols, plus the implied information-theoretic bit count. term_glossary defines terms like peg, codemaker, minimax strategy, entropy and answer list. variant_info explains one of 15+ named variants (mini/mega sizes, blank-peg, duel, team relay, speed, cooperative, hidden-length, accessible, daily/themed word puzzles, battle royale, digit relay). find_game_for_group suggests game types and variants that fit a given number of players. beginner_tips gives a ranked shortlist of the most useful tips for someone brand new to this game family. Keyless; fully local; zero upstream calls; nothing stored.

What it is not

Not an official product of, or affiliated with, any brand, league, publisher, or organization it may factually mention. Codepeg is a hand-curated reference and design tool, not a substitute for an official rulebook, certified instruction, or professional advice. Fully local, zero upstream calls, nothing stored.

Tools

Look Up

mechanic_info — Explains one generic named mechanic used across code-breaking and feedback-guessing games — feedback types, scoring rules, setup knobs, strategy techniques, rule variants and formats. Use for "what does minimax mean here", "how does duplicate-color scoring work". Args: name.

game_type_list — Every core game type this reference covers, with its default code length, symbol-pool size, whether repeats are allowed by default, typical player count and difficulty. Use for "what kinds of code-breaking games do you cover".

term_glossary — Definitions of common code-breaking / feedback-guessing terms — peg, code, codemaker, exact/partial match, minimax strategy, entropy, tile, answer list, worst-case guess bound, .... Use for "what's a partial match", "what does entropy mean here". Args: term.

variant_info — Full detail for one of 15+ named variants of these games — size variants, duel and battle-royale formats, party/team formats, accessible and daily-puzzle formats. Use for "what's speed mode", "what's a battle royale version of this". Args: name.

Play & Strategize

optimal_strategy_tip — Five concrete strategy tips for playing one game type well, covering opening guesses, reading feedback, and elimination technique. Use for "what's the best strategy for guessing", "how do I open a round". Args: game_type.

feedback_system_explainer — Explains exactly how one game type's feedback works after a guess — e.g. black/white (exact/partial) peg counts, or green/yellow/gray letter tiles — including how repeated symbols are scored without double-counting. Use for "how does the feedback work", "what do the colored tiles mean". Args: game_type.

beginner_tips — A curated, ranked shortlist of the most useful tips for someone brand new to this whole family of code-breaking and feedback-guessing games. Use for "I'm new to this, what should I know", "tips for a beginner". Args: count.

Math & Recommendations

combinatorics_note — A REAL combinatorics calculation: exactly how many possible codes exist for a given code length and symbol-pool size, computed both with and without repeated symbols allowed, plus the implied information-theoretic bit count. Use for "how many possible codes are there with 4 slots and 6 colors", "how big is the search space for a 5-letter word". Args: game_type, code_length, colors_or_letters, allow_repeats.

find_game_for_group — Suggests game types and variants suited to a given number of players — from solo word-guessing to large team-relay or battle-royale formats. Use for "what's a good code-breaking game for 6 people", "any version of this for one player". Args: player_count.

Conventions

• Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
• Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
• Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Codepeg — Privacy Policy

Effective 25 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Codepeg is. Codepeg is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for a hand-curated code-breaking & feedback-guessing game reference — mechanics, strategy and real combinatorics. You interact with your assistant; the assistant sends us only the arguments needed for that one lookup.

What we receive. The arguments of each tool call, the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Everything is answered from a bundled, hand-curated reference file and nothing is stored. No request is forwarded to any third party — there is no upstream call at all, live or otherwise — and no query is logged in request bodies, recorded, or used to train anything.

What we do not receive or store. We do not receive your conversation with the assistant or your name, and we do not build a profile from your queries: each request is answered independently and nothing carries over between requests. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. None — the entire dataset is bundled with the server and answered locally. Hosting: Vercel (United States regions).

Legal bases and your rights. Our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. Codepeg is a general-audience service operated by the adult using the assistant.

Changes. We will post changes here with a new effective date.
