Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

A line of code looks encrypted vite.config.ts:15

    "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJzdXBhYmFzZSIsInJlZiI6ImJ6eG1lanpzc3hqYXpzd2d3cXFzIiwicm9sZSI6ImFub24iLCJpYXQiOjE3NjA3MDI4NjcsImV4cCI6MjA3NjI3ODg2N30.U10RsJRxIm3zPWcJPHpHuKf0X6FGO6P1bj4c21PN42o",

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 39

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

bazaar

bazaar_discover_mcp_servers

Discover third-party MCP servers published in Coinbase CDP's Bazaar. Read-only. Filter by free-text q and/or network.

bazaar_discover_resources

Discover third-party x402-paid resources published in Coinbase CDP's Bazaar (docs, data feeds, AI inference, etc). Read-only. Filter by free-text q and/or network (e.g. 'base').

bazaar_pay_and_call

Pay and call any x402-paid HTTPS endpoint using the merchant agent's CDP MPC wallet (EIP-3009 exact scheme on Base USDC). Probes the URL for HTTP 402, picks a compatible requirement, signs TransferWithAuthorization via CDP, retries with X-PAYMENT header, and returns the paid response. Requires scope 'mint' and a pre-created CDP wallet. Safety cap: max_usdc (default 0.25, hard limit 10).

bazaar_probe_x402

GET a candidate x402 URL and, if it responds HTTP 402, return the parsed payment requirements (accepts[]) so the caller can decide whether to pay. HTTPS only. No signing performed.

program

get_program_analytics

Get analytics for your loyalty programs

get_program_workflow_status

Explain the next merchant action: current_step, required fields, and ordered next_actions (you provide all parameter values)

update_program_config

Update default cashback_rate and/or points_per_dollar for a program (same as merchant dashboard sliders)

update_program_status

Update program status in database after onchain activation/pause

gift

create_gift_certificate

Create a gift / welcome certificate (UDS-style) with a unique 6-character redemption code (LOYAL-XXXXXX). Customer redeems via QR or by entering the code; merchant then mints tokens on-chain. Use for welcome bonuses, promo campaigns, partnership gifts.

list_gift_certificates

List gift certificates issued by the agent's merchant (with status and redemption info).

loyalty

create_loyalty_program

Get factory calldata to deploy a new loyalty token on Base. Defaults to B20 (Base native ERC-20 superset, single tx, active immediately). Pass token_standard='erc20' for the legacy factory. For B20, MINT_ROLE is granted atomically to the merchant admin AND to the agent's CDP wallet (or explicit extra_minters) so autonomous agents can mint with no follow-up transaction.

list_loyalty_programs

List loyalty programs owned by the agent's merchant

platform

get_platform_info

Get info about Loyal Spark protocol on Base L2

get_platform_stats

Get global platform statistics across all merchants. Admin-only: requires agent owned by an admin wallet.

report

delete_report

Delete a report that is no longer relevant. Use to clean up outdated or irrelevant reports.

update_report_status

Update report status to 'reviewed' or 'done'. Use 'done' when the action items have been completed. Use 'reviewed' to acknowledge a report.

reward

create_reward

Create a new reward redeemable with loyalty tokens

update_reward_status

Activate or deactivate a reward in the catalog. Use to manage reward availability based on analytics.

activate

activate_loyalty_program

For legacy ERC-20 programs: returns unpauseUtility + enableMinting calldata. For B20 programs: no-op (already active).

cancel

cancel_stale_offers

Cancel marketplace offers that have been active for more than N days with no completions. Admin-only action tool.

confirm

confirm_mint_fee

Confirm that the protocol fee transaction for a previous mint/earn was broadcast on Base. Verifies the fee mint on-chain and clears the obligation. Unconfirmed fee obligations block future mints.

earn

earn_points

Calculate and mint loyalty tokens based on purchase amount and program's cashback rate. Returns a fee-first `calls[]` bundle (protocol fee mint first, then the customer mint) — submit in order, atomically via EIP-5792 if supported, then call confirm_mint_fee (or POST /agent-api/mint/confirm). Unconfirmed fee obligations block future mints.

export

export_customers

Export customer data for a specific loyalty program. Returns wallet addresses, voucher stats, balances, and tier info. Use for analytics, segmentation, and personalized offers.

generate

generate_program_defaults

Workflow planner: field catalog, required parameters, next_actions, and non-binding examples. External agents must choose their own name, symbol, and economics.

mark

mark_gift_certificate_minted

After the merchant submits the on-chain mint transaction for a claimed gift certificate, call this to mark it as minted (status pending_mint → redeemed) and store the mint tx hash.

marketplace

list_marketplace_offers

List active token trading offers on the marketplace

mint

mint_loyalty_tokens

Record mint intent and get a fee-first `calls[]` bundle: protocol fee mint FIRST, then the recipient mint. The protocol fee is charged in the merchant's own loyalty tokens (not USDC). Submit both calls in order (atomically via EIP-5792 send_calls if your wallet supports it), then call confirm_mint_fee (or POST /agent-api/mint/confirm) with the fee tx hash. Unconfirmed fee obligations block future mints.

personalized

create_personalized_offer

Create a personalized offer for a specific customer. Use when analytics reveal engagement patterns (e.g., inactive customers, high-value segments).

profile

get_my_profile

Get authenticated agent's profile

redeem

redeem_reward

Redeem a reward by providing a verified token transfer transaction hash. Creates a voucher for the customer.

register_loyalty_program

Register a deployed token as a loyalty program in the database. B20 tokens are registered as active; legacy ERC-20 as inactive (activate next).

reports

list_my_reports

List your previously submitted reports. Allows reviewing past reports, checking status (new/reviewed/done), and identifying what still needs attention.

revoke

revoke_gift_certificate

Revoke an active gift certificate (status active → revoked). Only the issuing merchant can revoke. Already-redeemed/minted certificates cannot be revoked.

rewards

list_rewards

List rewards for a loyalty program by token_address. Includes redemption metrics (total vouchers issued, redeemed, and last-30-day counts) for each reward.

send

send_report

Send a report to the developer/owner. Use this to submit SEO audits, growth ideas, data reports, anomalies, recommendations, or weekly summaries. The report will appear in the merchant's Agent Reports dashboard.

token

get_token_balance

Get loyalty token balance and tier info for a customer

transfer

transfer_loyalty_tokens

Get calldata to transfer loyalty tokens between wallets

use

use_voucher

Mark a voucher as used (redeemed by customer at merchant). Merchant-only operation.

voucher

check_voucher_status

Check voucher status by code or ID. Public endpoint — no API key or authentication required.

Loyal Spark — questions

Answers built from our own checks of this server.

What can Loyal Spark do?

It exposes 39 tools, read directly from the server on our last check. Among them: activate_loyalty_program, bazaar_discover_mcp_servers, bazaar_discover_resources, bazaar_pay_and_call, bazaar_probe_x402, cancel_stale_offers and 33 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Loyal Spark mostly used for?

Its tools cluster around program, bazaar and loyalty. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Loyal Spark working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 570 ms. The bar chart above shows every period we have measured.

How do I connect Loyal Spark?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Loyal Spark need an API key?

No. Loyal Spark completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 39 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Loyal Spark?

It answers our handshake in 570 ms on average, which is faster than 23% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Loyal Spark open source?

Yes — it is published under the MIT licence, written in TypeScript and 13 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
