Tool list

Not read: It requires a setting the publisher marks as required (for example a URL part or a configuration value) that has no default, so we did not start it. So there is no tool-list size and no result from the three APIs.

Worth knowing before you connect it

Its package is signed and carries a build record naming its source.

Dead or stale signals

None found in the records we hold

Looked for and not found: deprecated in the registry; listed version cannot be installed or is withdrawn; repository link does not open; repository archived; no push in over 365 days. Each line is a dated fact from a public record. It does not say whether the server still works, and a record can change after the date shown.

Changes since the last refresh

Version 0.1.8 (published 2026-11-02) → 0.1.9 (published 2026-11-02), between the registry lists of 2026-11-02 and 2026-11-03.

The publisher published no GitHub release note for this version: its repository publishes no GitHub releases.

The MCP Inspector lists the server's tools, resources and prompts; a tool you call there runs for real.

Built from the server's registry entry with each client's documented format (checked 2026-10-14; the Cursor link and the VS Code command 2026-10-19; the MCP Inspector command 2026-10-21; Cline, Gemini CLI, OpenAI Codex and Zed 2026-10-26). Values in < > are yours to fill in; this page never contains a key. Where the server needs a setting the entry does not declare, it can still fail to start.

Does the registry listing match what we found?

Feature #6

The registry checks an entry when it is published (each new version), and nothing re-checks it on a schedule. A difference below is about the listing, not a judgement of the publisher.

Common questions about network.luca/spr-mcp

Answered from the data above

Who publishes network.luca/spr-mcp?

The registry ties the namespace network.luca to the domain luca.network; only its owner can publish under it. Its linked repository is github.com/luca-network/spr; GitHub reports its owner as luca-network, an organization. These are facts from the registry and GitHub, not a rating.

Is network.luca/spr-mcp safe to install?

We do not rate servers as safe or unsafe. 9 of its 9 applicable record checks are met (facts from public records, each listed on this page). What the records show: Its npm package carries a build-provenance attestation that names its source repository and build workflow. Its source repository opens publicly. Its repository had a push in the last 90 days. The listed version is the latest stable release. The package itself has no known vulnerability (OSV.dev). Its full dependency tree has no known advisory. These are facts with their sources on this page, not a safety guarantee, and we did not run its tools.

Has network.luca/spr-mcp been security tested?

No. It requires a setting the publisher marks as required (for example a URL part or a configuration value) that has no default, so we did not start it.

Does network.luca/spr-mcp publish a security policy?

Yes: its repository has a public security policy (github.com/luca-network/spr/blob/HEAD/SECURITY.md). That is the publisher's statement, not permission for us to test the server, and we call none of its tools.

Is the listed version current?

Yes. The registry lists 0.1.9, the latest stable release on npm.

Where is the source code of network.luca/spr-mcp?

In github.com/luca-network/spr, which opens publicly.
