Trust breakdown (7 categories)

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. How we score → Why this is hard to score →

Supply Chain Security0
  • No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
  • Known CVEs could not be checked: this image's dependency list comes from an SBOM its publisher attached, which nothing verifies, so we will not report it as a clean result.Unverified
  • Install-script risk not yet assessed.Unverified
  • Dependency health could not be checked: this image's dependency list comes from an SBOM its publisher attached. It names packages and versions but not whether each is deprecated, still maintained or linked to its source, so there is nothing we can fairly grade.Unverified
Provenance & Transparency48
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
  • Clear OSI-approved license (Apache-2.0).Pass

  • Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability69
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 3872 tokens (~129/item across 30 items; 30 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 Management53
  • Stability observed for 16 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • 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
  • All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
  • An AI judge read all 30 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

MCP tools · 30 exposed · ~3,872 tokens

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 →

Tool Tokens
account_settings ~72

Read the account's quota windows, or set the output language when output_language is given. The language setting slot is not live-verified (the call is sent, but Google may ignore or reject it).

chat_ask ~241

Ask a question about a notebook's sources. Streams partial text as progress notifications. Returns the answer, citations (source, cited text, UTF-16 offsets) and the conversation id. save_as_note also saves the answer as a note (note_id, or note_error when it could not be saved). wait=false returns a job_id; poll with chat_status. Not retried after sending.

chat_configure ~125

job_idstringyesjob id returned by chat_ask with wait=false

Structured output declared, but exposes no named fields.

No examples provided.

delete ~223

Delete notebooks, sources, notes, artifacts, chat history, labels or collections. Without confirm:true it only returns a preview of what would be deleted and changes nothing. Items are matched strictly (exact id, unique id prefix or exact title) against a fresh list. source, note and chat_history need notebook; chat_history deletes the whole history of the given conversations; it reaches only the newest 20 conversations of a notebook, and its preview shows their created and updated times and, when the whole history can be read, the first question. Kinds artifact, label and collection are not available yet and return UNSUPPORTED_BY_TRANSPORT.

Widening access or removing people requires confirm:true; without it a preview is returned and nothing is sent. The link setting and the user changes are sent as two calls; if only one applies, status is partial and parts says which applied and which failed.

studio_generate ~448

Generate a Studio artifact: audio, video, report, interactive_report, slide_deck, mind_map, quiz, flashcards, infographic or data_table. Each kind takes only the option values a live capture has proven (the enums); other values the web app offers return UNSUPPORTED_BY_TRANSPORT naming the option, before any call. Omitted options take the web app's defaults. instructions is optional for audio, video, slide_deck and quiz, required for report, mind_map, flashcards and data_table, and refused by infographic and interactive_report (each as captured). video.generate_later asks for deferred generation (cinematic format only). report needs report.title and report.description plus instructions as the prompt (suggest surface report returns ready-made triples). Checks the account quota first and returns a QUOTA error when it is used up. Artifacts are built from the notebook's sources only, not notes (the web app can add notes; that is not supported). Returns the new artifact as pending; poll studio_list for its status. Not retried after sending.

Install

How do I install the sourcebolt MCP server?

sourcebolt runs locally as a container image, launched with docker run --rm -i ghcr.io/candidloom-hub/sourcebolt:0.3.3. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

Common questions

What is the sourcebolt MCP server?

sourcebolt is an MCP server listed in the public MCP registry as io.github.candidloom-hub/sourcebolt. Fast MCP server for Google NotebookLM: notebooks, sources, cited chat, research. Unofficial. This page covers its container image (ghcr.io/candidloom-hub/sourcebolt).

Is the sourcebolt MCP server safe to use?

sourcebolt scores 47 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 sourcebolt MCP server expose?

sourcebolt exposes 30 tools: account_settings, auth_login, auth_logout, chat_ask, chat_configure, and 25 more. Their descriptions and schemas cost roughly 3,872 tokens of context every time the server is loaded.

Is the sourcebolt MCP server still maintained?

sourcebolt 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 sourcebolt MCP server under?

sourcebolt declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
