Is @blockrun/llm safe?

No malicious indicators - review capabilities before installing
Notable — review in context (a capability is not a malicious indicator):
  • Node.js filesystem read
  • Node.js filesystem write/delete
  • Node.js network egress

What to do: Nothing here argues against installing it. Grant the capabilities it lists only if you expect the tool to need them.

@blockrun/llm is an npm package analyzed by SkillTotal's deterministic static scanner. The scan found no malicious indicators. It can: filesystem read, filesystem write and network egress — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).

Findings (3)

CapabilityNode.js filesystem readnot scored · severity mediumST-FS-NODE-READ

The component reads files from disk.

const content = fs.readFileSync(COST_LOG_FILE, "utf-8").trim();
const content = fs.readFileSync(COST_LOG_FILE, "utf-8").trim();

Why it matters: Usually legitimate, but worth confirming it can't be steered into reading sensitive files.

Fix: Confirm which files are read and that paths cannot be influenced by untrusted input to reach sensitive locations.

CapabilityNode.js filesystem write/deletenot scored · severity mediumST-FS-NODE-WRITE

The component writes or deletes files on disk.

fs.appendFileSync(COST_LOG_FILE, JSON.stringify(entry) + "\n");
fs.appendFileSync(COST_LOG_FILE, JSON.stringify(entry) + "\n");

Why it matters: Usually legitimate, but worth confirming the paths can't be controlled by untrusted input.

Fix: Confirm which files are written/deleted and that paths cannot be influenced by untrusted input.

CapabilityNode.js network egressnot scored · severity mediumST-NET-NODE

The component makes outbound network requests.

async fetch(input, init, raiseErrors = true) {
response = await globalThis.fetch(request ? new Request(url, request) : url, {
const res = await this.fetch(url, { signal: AbortSignal.timeout(remaining) });
const response = await fetch(rpc, {
const response = await fetch(rpcUrl, {
const response = await fetch(rpcUrl, {
const probe = await fetch(url, { method: "GET" });
const response = await fetch(this.rpcUrl, {
if (this.apiAuth) return await this.apiAuth.fetch(input, mergedInit, false);
let response = await globalThis.fetch(input, mergedInit);
response = await globalThis.fetch(input, {
async fetch(input, init, raiseErrors = true) {
response = await globalThis.fetch(request ? new Request(url, request) : url, {
const res = await this.fetch(url, { signal: AbortSignal.timeout(remaining) });
const response = await fetch(rpc, {
const response = await fetch(rpcUrl, {
const response = await fetch(rpcUrl, {
const probe = await fetch(url, { method: "GET" });
const response = await fetch(this.rpcUrl, {
if (this.apiAuth) return await this.apiAuth.fetch(input, mergedInit, false);
let response = await globalThis.fetch(input, mergedInit);
response = await globalThis.fetch(input, {

Why it matters: Usually legitimate, but confirm the destinations are expected and no sensitive data leaves.

Fix: Confirm the destination hosts are expected and that no sensitive data is sent off-host.

Check the next package before your agent installs it

The free Claude Code plugin scans each npm, PyPI or MCP package with this report's open-source engine before the install command runs. It runs on your machine and needs no account.
