MCP tools · 10 exposed · ~1,588 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
xsolana_check ~174

Check an economy spec: refusals (each with a code, what it means and its fix) stop it from going live; warnings are what the person must hear (chance that pays money, revenue paid to stakers, an unfunded prize, a grant without limits, a mint’s powers). Run it after every change. Give the spec inline (`spec`), a file, or an example.

NameTypeReqDescription
examplestring–A worked example by name, from xsolana_examples (coin-flip-arena, stud-farm, …).
filestring–A JSON file holding the spec, relative to the project folder (default: xsolana.json when it exists).
specobject–An economy spec (version 2) given inline. Takes precedence over file and example.

No output schema declared.

No examples provided.

xsolana_client ~79

How an app (a game, a site, a bot) uses a live economy: the program’s address and cluster, the npm package and IDL, and the calls a page makes with the player’s own wallet (open a box, buy, stake, craft, enter, claim). Use this instead of writing chain code from memory.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

xsolana_cost ~134

What going live costs (each account’s rent, the program’s fees, network fees, the seeds, the transactions and wallet approvals it takes) and what each action costs whoever signs it while it runs.

NameTypeReqDescription
examplestring–A worked example by name, from xsolana_examples (coin-flip-arena, stud-farm, …).

specobject–An economy spec (version 2) given inline. Takes precedence over file and example.

No output schema declared.

No examples provided.

xsolana_examples ~211

Find an economy to start from. With `query` (the person’s own words, as they said them), returns the closest worked examples (whole specs that check and go live in the tests), the closest of 112 real or trending economies rated against loot (great / some / a-lot / cannot, with what carries it or what is missing), and what loot can’t do exactly in the ask, each with the nearest versions it can. Call it again with the words of any part that looks impossible: the answer is a nearest version to offer, not a dead end. With `name`, returns that example’s whole spec to copy and change. With neither, lists every example.

NameTypeReqDescription
fitstring–Only ideas with this fit.
limitinteger–How many of each kind (default 6).
namestring–An example’s name, to get its whole spec.
querystring–What the person wants, in a few words.

No output schema declared.

No examples provided.

xsolana_explain ~158

The economy in plain words for the person: what players do and what it costs and is worth, how the pools fill and drain, what runs by itself, what the authority must sign, what going live costs, and what is flagged for the law. Tell them the essentials in a few lines, from this text.

NameTypeReqDescription

xsolana_guide ~209

Read this first whenever someone wants a web3 economy, game economy, token economy, NFT mechanic or onchain reward system: a shop, loot boxes or packs, gacha, a lottery or raffle, an auction (highest bid wins, the outbid refunded at once), staking or a farm, crafting or merging, seasons and emissions, a prediction pool or contest, quests and airdrops, holder-gated drops, using NFTs of any other collection in a game. loot is ONE shared Solana program (devnet until it is audited): the economy is a JSON spec, not a new smart contract, so never write Anchor/Rust for what it covers. Returns every part an economy can have (fields from the schema, who acts at play time, fees), how to write a spec, and what loot cannot do (with the nearest alternative). Pass `part` for one part with its nested shapes.

NameTypeReqDescription
partstring–One part, with its nested shapes.

No output schema declared.

No examples provided.

xsolana_publish ~199

When the person says to put it live: returns what going live does (every step, in order, and its cost) and the one command they run themselves to approve it in their own wallet (`npx -y @xgamesfun/solana@0.20.1 approve`, pinned to this exact version: give it as it is): it opens a local page where they connect a devnet wallet and approve each transaction. You never sign, never ask for a key, and never run the approval for them.

NameTypeReqDescription
examplestring–A worked example by name, from xsolana_examples (coin-flip-arena, stud-farm, …).
filestring–A JSON file holding the spec, relative to the project folder (default: xsolana.json when it exists).
specobject–An economy spec (version 2) given inline. Takes precedence over file and example.

No output schema declared.

No examples provided.

xsolana_save ~108

Save a spec into the project (default xsolana.json), only if it checks. A file that is already live keeps its program numbers and its live section. Never put a key in it: the checker refuses one.

NameTypeReqDescription
filestring–A JSON file holding the spec, relative to the project folder (default: xsolana.json when it exists).
specobjectyesAn economy spec (version 2) given inline. Takes precedence over file and example.

No output schema declared.

No examples provided.

xsolana_simulate ~239

The quick simulation (expected values from the spec, instant): what each box, ticket and craft gives back against its price, the house edge, each pool’s money in and out per day and whether it runs dry, settles or grows, farm rewards per unit staked, what players, the treasury and the platform get each day. `scenario` overrides the spec’s own ({"perDay": {"box:flip": 1000}, "days": 30, "staked": {"<farm>": 1000}}). Quote its numbers; never your own arithmetic.

NameTypeReqDescription
examplestring–A worked example by name, from xsolana_examples (coin-flip-arena, stud-farm, …).
filestring–A JSON file holding the spec, relative to the project folder (default: xsolana.json when it exists).

scenarioobject–What to assume instead of the spec’s scenario.
specobject–An economy spec (version 2) given inline. Takes precedence over file and example.

No output schema declared.

No examples provided.

xsolana_status ~77

A live economy as it is on chain: the project, every pool’s balance, every record the spec names (found or missing). Reads devnet (or XSOLANA_RPC_URL).

Is the xsolana MCP server safe to use?

xsolana scores 78 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the xsolana MCP server expose?

xsolana exposes 10 tools: xsolana_guide, xsolana_examples, xsolana_check, xsolana_simulate, xsolana_cost, and 5 more. Their descriptions and schemas cost roughly 1,588 tokens of context every time the server is loaded.

Is the xsolana MCP server still maintained?

xsolana is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the xsolana MCP server under?

xsolana declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
