Available components
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 Security99
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
- 12 of 58 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- 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 (MIT).Pass
- Actively maintained (last published 166 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability80
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1710 tokens (~41/item across 41 items; 40 tools + 1 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: two runs of the same published version returned different tool surfaces, so we cannot tell a change in the package from a difference in our own sandbox run.Unverified
Tool Coverage98
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 92% of tool parameters carry a description.Partial
- Structured output schemas are declared (98% of tools); any adoption earns full credit.Pass
Tool Safety50
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "tube_send" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- Manipulation not yet verified: only 38 of 41 captured unit(s) of tool text has been judged so far, so we will not certify text no model has read as clean.Unverified
Capabilities100
- Implements a current MCP spec version (2026-07-28).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.
How do I install the io.github.daedalus/mcp-pwntools server?
io.github.daedalus/mcp-pwntools runs locally as a PyPI package, launched with uvx mcp-pwntools. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 →

What is the io.github.daedalus/mcp-pwntools server?
io.github.daedalus/mcp-pwntools is listed in the public MCP registry as io.github.daedalus/mcp-pwntools. MCP server exposing pwntools 4.15.0 functionality for binary exploitation. This page covers its PyPI package (mcp-pwntools).
Is the io.github.daedalus/mcp-pwntools server safe to use?
io.github.daedalus/mcp-pwntools scores 68 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. 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 io.github.daedalus/mcp-pwntools server expose?
io.github.daedalus/mcp-pwntools exposes 40 tools: p8, p16, p32, p64, u8, and 35 more. Their descriptions and schemas cost roughly 1,692 tokens of context every time the server is loaded.
Is the io.github.daedalus/mcp-pwntools server still maintained?
io.github.daedalus/mcp-pwntools is still listed as active in the MCP registry. We last reached this channel on 20 September 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 io.github.daedalus/mcp-pwntools server under?
io.github.daedalus/mcp-pwntools declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
