Took me a few hours to get it fully configured. Docs are okay but skip over some setup steps that tripped me up. Once it was going, pretty…

This is one of those tools where you're not sure what you were doing before it existed. Just works, every time.

03SECURITYWHAT WE CHECKED

Security flags foundOur static scan found signals worth reviewing before you trust this with an agent. See exactly what, per check, below.

Telemetry disclosureUndisclosed egress detected.Static checks found network calls the docs do not mention. Disclosed telemetry is common and fine, silent telemetry is the finding.

Security tierTier 1, Contained.No network access and no credentials. Runs entirely on its own. What tiers mean

Install-time hooks & dependencies1 finding

HIGHtest/resources/repos/svelte/test_repo/package.json — npm 'prepare' lifecycle hook: install hook runs a command that fetches from the network, pipes to a shell, or runs an encoded/inline-interpreter command: the arbitrary-code-on-install supply-chain vector.

Runs code / shell commands87 findings

MEDIUMrepo_dir_sync.py:57 — Code-execution surface: a os.system() call site. The server can run commands on the host; review what it executes and whether any input reaches it.

MEDIUMrepo_dir_sync.py:176 — Code-execution surface: a os.system() call site. The server can run commands on the host; review what it executes and whether any input reaches it.

MEDIUMrepo_dir_sync.py:294 — Code-execution surface: a os.system() call site. The server can run commands on the host; review what it executes and whether any input reaches it.

MEDIUMrepo_dir_sync.py:298 — Code-execution surface: a os.system() call site. The server can run commands on the host; review what it executes and whether any input reaches it.

Secrets & credentials2 findings

INFOsrc/solidlsp/language_servers/intelephense.py:139 — Reads a secret-shaped environment variable. Ordinary for a credentialed server; recorded for completeness.

INFOsrc/solidlsp/language_servers/pascal_server.py:250 — Reads a secret-shaped environment variable. Ordinary for a credentialed server; recorded for completeness.

Network calls out120 findings

MEDIUMtest/solidlsp/svelte/test_svelte_symbols.py:3 — Hardcoded external endpoint 'github.com'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

MEDIUMtest/solidlsp/systemverilog/test_systemverilog_detection.py:192 — Hardcoded external endpoint 'github.com'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

MEDIUMtest/solidlsp/util/test_ls_utils.py:29 — Hardcoded external endpoint 'marketplace.visualstudio.com'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

MEDIUMtest/solidlsp/rust/test_rust_analyzer_detection.py:46 — Hardcoded external endpoint 'github.com'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

Prompt-injection passthrough1 finding

INFOsrc/solidlsp/ls.py — HEURISTIC: this file both fetches external content and returns content as tool output, with no obvious sanitization. External text returned into tool output can carry instructions an agent obeys (prompt-injection passthrough). Confirm manually; this is a hint, not proof.

Permission scope breadth6 findings

INFOtest/conftest.py — HEURISTIC: broad capability surface in one file (filesystem, network, subprocess). A scope-breadth hint: the more distinct host capabilities a server touches, the more a buyer is granting. Confirm it matches the stated function.

INFOtest/solidlsp/php/test_php_basic.py — HEURISTIC: broad capability surface in one file (filesystem, network, subprocess). A scope-breadth hint: the more distinct host capabilities a server touches, the more a buyer is granting. Confirm it matches the stated function.

INFOsrc/solidlsp/ls_utils.py — HEURISTIC: broad capability surface in one file (filesystem, network, subprocess). A scope-breadth hint: the more distinct host capabilities a server touches, the more a buyer is granting. Confirm it matches the stated function.

INFOsrc/solidlsp/language_servers/julia_server.py — HEURISTIC: broad capability surface in one file (filesystem, network, subprocess). A scope-breadth hint: the more distinct host capabilities a server touches, the more a buyer is granting. Confirm it matches the stated function.

INFOsrc/serena/dashboard.py — HEURISTIC: broad capability surface in one file (filesystem, network, subprocess). A scope-breadth hint: the more distinct host capabilities a server touches, the more a buyer is granting. Confirm it matches the stated function.

INFOsrc/serena/util/dotnet.py — HEURISTIC: broad capability surface in one file (filesystem, network, subprocess). A scope-breadth hint: the more distinct host capabilities a server touches, the more a buyer is granting. Confirm it matches the stated function.

How to read this: these are static checks over the source at a point in time. They catch the patterns above, not everything. Absence of a flag is not absence of danger, and a tool that runs cleanly can still behave differently once installed. We do not call any tool simply "safe". Runtime-behavior checks are the next layer we are adding.
