## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.

## Common questions

### What is the Bcb Br MCP server?

Bcb Br is an MCP server listed in the public MCP registry as io.github.pipeworx-io/bcb-br. Banco Central do Brasil (Brazil's central bank) MCP. Keyless public APIs: SGS time series + Olinda… This page covers its npm package (@pipeworx/mcp-bcb-br).

### Is the Bcb Br MCP server safe to use?

Bcb Br scores 84 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 Bcb Br MCP server expose?

Bcb Br exposes 5 tools: sgs_series, indicator, list_indicators, ptax_usd, focus_expectations. Their descriptions and schemas cost roughly 611 tokens of context every time the server is loaded.

### Is the Bcb Br MCP server still maintained?

Bcb Br 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 Bcb Br MCP server under?

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

### What did VerifyMCP test on the Bcb Br MCP server?

VerifyMCP ran 16 checks on Bcb Br, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
