## 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)

Scored 2026-08-03.

- **Supply Chain Security**: 50/100
  - Malware scan not yet available for this package.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised native-build step with no shell scripting around it.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: the license (BSD License) isn't a recognized OSI-approved license.
  - Actively maintained (last published 0 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 74/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 443 tokens (~147/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

**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 (3)

### `perplexity_agent` (~196 tokens)

Perplexity Agent Research

Run a research query through Perplexity's Agent API (multi-step web research with citations). Use for deep or multi-hop questions where a single synthesized, sourced answer is wanted. With wait=true (default) this blocks until the answer is ready; if it takes too long you get a response_id to collect later with perplexity_agent_result.

Input parameters:

- `domains` (array): Restrict sources to these domains. Prefix with '-' to exclude. Allowlist or denylist, not both.
- `preset` (string): Research depth: fast, low, medium, high, xhigh, wide-research. Deeper takes longer.
- `query` (string, required): The research question.
- `recency` (string): Only use sources published within this window.
- `wait` (boolean): Block until the answer is ready. Set false to get a response_id immediately — useful for running several deep queries in parallel while you do other work.

### `perplexity_agent_result` (~114 tokens)

Collect Perplexity Research

Retrieve the result of a research run started by perplexity_agent. If it is still running, reports what it has done so far and how to check again.

Input parameters:

- `response_id` (string, required): The response_id from perplexity_agent.
- `wait_seconds` (integer): Block up to this many seconds waiting for completion. 0 checks once. A larger value is silently CLAMPED to this server's configured wait budget (55s here; set PERPLEXITY_AGENT_WAIT_SECONDS to raise i…

### `perplexity_agent_cancel` (~62 tokens)

Cancel Perplexity Research

Ask Perplexity to stop a research run that is no longer needed. Perplexity does not report usage for cancelled runs, so this cannot tell you whether it changed your bill.

Input parameters:

- `response_id` (string, required): The response_id from perplexity_agent.
