Which MCP Server Should You Choose?
Choose Mrmarket.ai when:
You need dedicated capabilities in the Finance & Fintech domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Analytical engine for US-listed equities: screens, rankings, and event studies in plain English.
Keyless, non-custodial crypto payments. Create crypto payment links and tip jars with just a wallet address, no API key, no signup. Funds settle directly to the merchant’s wallet. Remote at https://shieldz.cash/mcp or npx @shieldz/mcp.
The workhorse. A natural-language financial question in; structured rows and columns out. Screens, rankings, comparisons, time-series, cohort studies, and event studies are all single calls.
fetch_page
The continuation. When a `query_data` result is too large for one response, page 1 comes back with a `pagination.next_cursor`; pass that cursor to `fetch_page` to retrieve the rest. It runs no new query, so it never costs credits — the original `query_data` is charged once.
describe_data
The data catalog. Browse categories and fields, or search for a specific metric, before composing a question.
get_symbols
Fast ticker, sector, and industry resolution. Name to ticker, sector membership, or the full universe in under 50ms.
getting_started
A structured orientation tour with verified example prompts, grouped by use case.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Mrmarket.ai is categorized under Finance & Fintech and uses a remote streaming HTTP/SSE transport. In contrast, Shieldz MCP belongs to Finance & Fintech using local stdio subprocess. Select Mrmarket.ai when you need capabilities focused on finance & fintech and Shieldz MCP when you require tools for finance & fintech.
Connected account, plan tier, credit balance, and rate limits. A useful first call in any new session.
report_issue
Flag a result that looks wrong or a feature that is missing. Pass the `query_id` from the response so the trace can be investigated.
Shieldz MCP Tools (3)
create_payment_link
Create a one-time crypto payment link with ZERO setup, no account, no API key. Give a destination wallet address and an amount; get back a shareable pay_url, an embeddable button, and a manage_url. Non-custodial: funds settle directly to the address you provide. Optionally pass an email so the owner can claim a full dashboard later.
create_tip_jar
Create a reusable 'pay what you want' tip jar with ZERO setup, no account, no API key. The payer chooses the amount. Returns a shareable /tip url, an embeddable button, and a manage_url. Idempotent per wallet address: calling again updates the same tip jar. Non-custodial: funds settle directly to the address you provide.
get_account_status
Look up a keyless Shieldz account by its manage_token (returned when you create a payment link or tip jar). Returns settlement details, tip jars, totals (paid/pending), and the full invoice list as structured JSON.
