Category Search and Retrieval
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: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).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 (MIT).Pass
- Actively maintained (last published 5 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability64
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 938 tokens (~312/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 Coverage95
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 82% of tool parameters carry a description.Partial
- 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
- 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 supported MCP spec version (2025-11-25); the latest is 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.

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 →
find_tags Find how a tag is spelled ~124
Find how rule34.xxx spells a tag, and how many posts carry it. The site matches from the start of a name, so 'kimagure' finds 'kimagure_orange_road' while 'orange road' finds nothing. It offers at most ten names. Use this before searching when a name might be spelled differently, and after a search that found nothing because a tag does not exist.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | The start of a tag name, such as 'kimagure' or 'prince of tennis'. Spaces are joined with underscores. |
| Name | Type | Req | Description |
|---|---|---|---|
| notes | array | yes | – |
| query | string | yes | The text as rule34.xxx would spell it. |
| source | string | yes | – |
| tags | array | yes | – |
No examples provided.
get_post Read one post ~170
Read one rule34.xxx post, named by its id or by a link to its page. Returns every tag the post carries, each with its kind (character, copyright, artist, general or metadata) and how many posts share it, alongside the image or video, the dimensions, the score, the rating, the uploader, the number of comments, the credited source and the date the site took the post in. Use this after a search, whose rows show only the first few tags of each post.
| Name | Type | Req | Description |
|---|---|---|---|
| id | integer | – | The post's numeric id, as a search returns it. |
| url | string | – | A link to the post's page, such as https://rule34.xxx/index.php?page=post&s=view&id=2195419. The link is read rather than followed. |
| Name | Type | Req | Description |
|---|---|---|---|
| changed_at | string|null | yes | When the post last changed, ISO 8601. |
| comment_count | – | yes | – |
| created_at | string|null | yes | When the post was added to rule34.xxx, ISO 8601. The site imported much of its older catalogue in bulk, so thousands of posts share one day. |
| file_url | string | yes | – |
| has_notes | boolean | yes | – |
| height | integer | yes | – |
| id | integer | yes | – |
| md5 | string | yes | – |

search_posts Search posts by tag ~399
Search rule34.xxx for posts carrying a tag, or several tags at once. Tags are written as one token, so a name said as words is joined by underscores: 'asuka langley sohryu' and 'ranma 1/2' are single tags, and this tool joins them for you. Returns each post's page, its image or video URL, dimensions, score and rating, alongside the number of posts the whole search matches. A row shows the first 12 of a post's tags and says how many it has; call get_post for the whole list with a kind for every tag. Use 'media_type' to ask for still images, animations or video; the site classifies these itself. When a search finds nothing, the answer names the tags rule34.xxx does not hold, or says how many posts the tags match once the restrictions are dropped.
| Name | Type | Req | Description |
|---|---|---|---|
| any_of | array | – | Tags a post must carry at least one of. |
| exclude | array | – | Tags a post must not carry, such as ['monochrome'] to leave out black and white. |
| limit | integer | – | – |
| media_type | string | – | 'image' for stills, 'animated' for GIFs, 'video' for MP4. The site states this in its own tags, so the classification is as good as the tagging. |
| page | integer | – | – |
| rating | string | – | The two ratings rule34.xxx holds. Leave unset to search both. |
| sort | string | – | 'score' is the site's own tally of votes, recomputed once a day. 'id' is newest first. 'updated' is by when a post last changed, which retagging moves. 'random' draws a different set on each call. |
| tags | array | yes | Tags a post must all carry, such as ['asuka langley sohryu', 'black hair']. |
| Name | Type | Req | Description |
|---|---|---|---|
| any_of | array | yes | The alternatives, as rule34.xxx spells them. |
| exclude | array | yes | The excluded tags, as rule34.xxx spells them. |
| has_more | boolean | yes | – |
| next_page | – | yes | – |
| notes | array | yes | – |
| page | integer | yes | – |
| posts | array | yes | – |
| query | string | yes | The search as it was sent, in the site's own language. |
| source | string | yes | – |
| tags | array | yes | The required tags, as rule34.xxx spells them. |
| total | integer | yes | Posts the whole search matches, as counted by the site. |

How do I install the io.github.smeet666/mcp-rule34 server?
io.github.smeet666/mcp-rule34 ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 975341252eaee8f7e4f47a1e80c4afeec4eb50c72da70e4251b41ce44a1f1309; the commands to do that are on this page. If it does not match, do not open it.
