Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00122 | $0.03628 |
| Opus 5 | $0.00061 | $0.01814 |
| Sonnet 5 | $0.00024 | $0.00726 |
| Haiku 4.5 | $0.00012 | $0.00363 |
Grade A, and why
perplexity-web-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to perplexity-web-mcp — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 350 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Quick Reference
Run pwm --ai for comprehensive AI-optimized documentation covering all
commands, models, MCP tools, auth flows, and error recovery.
pwm --ai # Full AI reference (RECOMMENDED first step)
pwm --help # CLI help
pwm login --check # Check auth status
Critical Rules
- Authenticate first: Run
pwm loginbefore any queries - Tokens last ~30 days: Re-run
pwm loginon 403 errors - Default to
claude_opuswith--thinking --intent detailed-- always use the best model - Always output to file -- pipe to
/tmp/pwm-*.txt, never dump into conversation context - Never use Deep Research autonomously -- only when the user explicitly asks
Default Invocation
Every pwm ask call uses these flags -- no exceptions:
pwm ask "question" -m claude_opus --thinking --intent detailed > /tmp/pwm-TASKID.txt
-m claude_opus-- always explicit model, never barepwm askor auto/sonar--thinking-- always enabled--intent detailed-- always detailed (the standard research tier)- Output piped to
/tmp/pwm-*.txt-- never dump raw content into conversation context - No
-sflag by default -- no additional source focus unless the query specifically needs it - No
--jsonby default -- raw markdown is cleaner for file output. Add--jsononly when programmatic parsing is needed.
Rate Limiting and Parallelism
0.5 requests per second = 1 request every 2 seconds. When launching parallel requests, stagger by sleep 2 between each launch. Parallel execution is the default for independent queries.
# Parallel pattern with 2s stagger
pwm ask "Q1" -m claude_opus --thinking --intent detailed > /tmp/pwm-q1.txt &
sleep 2
pwm ask "Q2" -m claude_opus --thinking --intent detailed > /tmp/pwm-q2.txt &
sleep 2
pwm ask "Q3" -m claude_opus --thinking --intent detailed > /tmp/pwm-q3.txt &

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

perplexity-web-mcp is a skill published in the GitHub repository devdotbo/perplexity-web-mcp (15 stars, last pushed 4mo ago), licensed MIT. It adds 122 tokens to every session and 3,628 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to perplexity-web-mcp, differing in 0 lines, and is treated as a copy.
