Install

How do I install the MockHero MCP server?

MockHero is a hosted endpoint at https://mockhero.dev/mcp/agent, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 9 exposed · ~810 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
check_agent_checkout_status ~39

Poll a Polar checkout created by create_agent_checkout using the returned claim_token.

NameTypeReqDescription
tokenstringyesclaim_token returned by create_agent_checkout.

Structured output declared, but exposes no named fields.

No examples provided.

claim_agent_api_key ~47

Claim the MockHero API key after Polar marks the loginless agent checkout as paid. The key is returned once.

NameTypeReqDescription
tokenstringyesclaim_token returned by create_agent_checkout.

Structured output declared, but exposes no named fields.

No examples provided.

create_agent_checkout ~101

Create a loginless Polar Checkout URL for MockHero's metered agent plan. Polar is the Merchant of Record for checkout, tax collection, and remittance. The card payment step needs a human: present the returned url to your operator together with the estimate_agent_usage cost, keep the claim_token private, then poll check_agent_checkout_status and call claim_agent_api_key once paid.

NameTypeReqDescription
emailstringyesBilling email for the agent or the agent operator.

Structured output declared, but exposes no named fields.

No examples provided.

detect_schema ~61

Convert SQL CREATE TABLE statements or one sample JSON object into a MockHero schema that can be passed to generate_test_data.

NameTypeReqDescription
sample_jsonobjectSingle example JSON object to infer fields from.
sqlstringSQL CREATE TABLE statement or statements.

Structured output declared, but exposes no named fields.

No examples provided.

estimate_agent_usage ~210

Estimate MockHero agent-plan cost before generating data. No login or API key is required; include an API key only when you want the estimate to use actual daily usage.

NameTypeReqDescription
api_keystringOptional MockHero API key for no-auth MCP clients. Prefer the Authorization header when the client supports it.
daily_used_beforeintegerOptional assumption when no API key is supplied.
estimated_recordsintegerRequired for prompt estimates because this tool does not run prompt-to-schema conversion.
formatstring
localestringDefault locale such as en, de, fr, es, or ja.
promptstringPlain-English data request. Example: 50 users and 200 orders linked to them.
scalenumberMultiplier for template record counts.

Structured output declared, but exposes no named fields.

No examples provided.

generate_from_template ~126

Generate realistic test data from a pre-built MockHero template: ecommerce, blog, saas, or social. Small template previews up to 100 records can run free; larger or production usage requires a MockHero API key.

generate_test_data ~172

Generate realistic JSON, CSV, or SQL test data from structured tables or a plain-English prompt. Explicit table schemas up to 100 records can run free as a proof-of-work preview; plain-English prompt generation, larger requests, and production usage require a MockHero API key.

Common questions

What is the MockHero MCP server?

MockHero is an MCP server listed in the public MCP registry as io.github.dinosaur24/mockhero. Generate realistic relational test data, 156 field types, 22 locales, JSON/CSV/SQL, free previews. This page covers its hosted endpoint (https://mockhero.dev/mcp/agent).

Is the MockHero MCP server safe to use?

MockHero scores 25 out of 100 on VerifyMCP. 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 MockHero MCP server expose?

MockHero exposes 9 tools: estimate_agent_usage, create_agent_checkout, check_agent_checkout_status, claim_agent_api_key, generate_test_data, and 4 more. Their descriptions and schemas cost roughly 810 tokens of context every time the server is loaded.

Does the MockHero MCP server require authentication?

No. We connected to MockHero without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the MockHero MCP server still maintained?

MockHero is still listed as active in the MCP registry. We last reached this channel on 22 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
