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 Security50
- Malware scan not yet available for this package.Unverified
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to zalez/perplexity-agent-mcp). View diagnostics → Pass
- Clear OSI-approved license (classified as BSD License).Pass
- Actively maintained (last published 94 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability79
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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 →
perplexity_agent Perplexity Agent Research ~196
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | 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. |
No output schema declared.
No examples provided.
perplexity_agent_cancel Cancel Perplexity Research ~62
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.
| Name | Type | Req | Description |
|---|---|---|---|
| response_id | string | yes | The response_id from perplexity_agent. |
No output schema declared.
No examples provided.
perplexity_agent_result Collect Perplexity Research ~114
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.
| Name | Type | Req | Description |
|---|---|---|---|
| response_id | string | yes | 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… |
