How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability51
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 556 tokens (~278/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management60
- Stability observed for 18 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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 →
prepare_interpretation_delta_purchase Compare human instruction and agent interpretation — $0.001 ~204
Machine-native checks from $0.001 USDC per successful execution. No subscription required for S0.1 primitives. Browse the $0.001 primitive catalog. Create a purchase intent and pay only when /market.primitive_entry.paid_execution_enabled is true; otherwise paid execution is unavailable. Prepare a machine-payable x402 request. Check whether an agent's current interpretation materially differs from the original human message. Bounded instruction comparison: exact text equality or explicit boolean and permission polarity mismatch. Binary 0/1 when decidable; abstains before billing otherwise. Current deterministic scope: exact normalized text equality returns 0; true/false, yes/no, enabled/disabled, present/absent, required/not required and allowed/not allowed return 1. Other inputs abstain before billing. This is not general language interpretation, diagnosis or a similarity score.

prepare_state_deviation_purchase Compare expected versus actual state — $0.001 ~183
Browse the $0.001 primitive catalog. Create a purchase intent and pay only when /market.primitive_entry.paid_execution_enabled is true; otherwise paid execution is unavailable. Prepare a machine-payable x402 request. Check whether an observed state materially differs from an expected state. Compare expected versus actual system state for exact text equality or explicit boolean and configuration polarity mismatch, such as enabled versus disabled. Binary 0/1 when decidable; abstains before billing otherwise. Current deterministic scope: exact normalized text equality returns 0; true/false, yes/no, enabled/disabled, present/absent, required/not required and allowed/not allowed return 1. Other inputs abstain before billing. This is not general language interpretation, diagnosis or a similarity score.

How do I install the BIG Machine Market MCP server?
BIG Machine Market is a hosted endpoint at https://market.bruengerinvestmentgroup.com/mcp, 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.

What is the BIG Machine Market MCP server?
BIG Machine Market is an MCP server listed in the public MCP registry as io.github.417properties/big-machine-market. AI-native $0.001 interpretation and state-deviation checks over x402. This page covers its hosted endpoint (https://market.bruengerinvestmentgroup.com/mcp).
Is the BIG Machine Market MCP server safe to use?
BIG Machine Market scores 75 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 BIG Machine Market MCP server expose?
BIG Machine Market exposes 2 tools: prepare_interpretation_delta_purchase, prepare_state_deviation_purchase. Their descriptions and schemas cost roughly 387 tokens of context every time the server is loaded.
Does the BIG Machine Market MCP server require authentication?
No. We connected to BIG Machine Market without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the BIG Machine Market MCP server still maintained?
BIG Machine Market is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
