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 5.1 | $0.00155 | $0.01203 |
| Opus 5 | $0.00077 | $0.00602 |
| Sonnet 5 | $0.00031 | $0.00241 |
| Haiku 4.5 | $0.00015 | $0.00120 |
Grade A, and why
reddit-mcp-post 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
r/mcp Post
r/mcp is the subreddit for the Model Context Protocol — readers are agent developers, tool builders, and integrators who care about MCP servers, clients, and spec details. Reddit's post composer accepts markdown directly, so the script just splits the YAML frontmatter from the body and pipes the body to pbcopy.
Quick start
- Gather from the user: project / topic, key technical points, repo URL, which MCP clients have been tested (Claude Desktop, Cline, Continue, Cursor, Zed, etc.), transport (stdio / Streamable HTTP / SSE), and post type (Show & Tell vs Discussion / Help).
- Pick a template — templates/show-and-tell.md.tmpl for project announcements, templates/discussion.md.tmpl for spec / design questions or troubleshooting.
- Draft to
/tmp/reddit-mcp-post.md. Frontmatter must includetitle:; optionallyflair:. - Run
bash .claude/skills/reddit-mcp-post/scripts/copy.sh /tmp/reddit-mcp-post.md— body markdown lands on the clipboard; title and flair print to stderr. - Tell the user to paste the title into Reddit's title field, select the flair from the dropdown, switch the editor to Markdown mode, and paste the body.
Post shape
| Mode | Word target | Use for |
|---|---|---|
| Show & Tell | 200–600 words | "I built an MCP server / client for X" |
| Discussion / Help | 100–400 words | Spec questions, transport debugging, design opinions |
Always include: which MCP client(s) you tested with, which transport, which spec version (2024-11-05 / 2025-03-26 / 2025-06-18). r/mcp readers ask these in the comments anyway — pre-empt them.
Frontmatter format
---
title: "Show & Tell: file-search-on — content-type-aware file search as an MCP server"
flair: Show & Tell
---
title:is required. Keep under 300 chars (Reddit's hard cap); under ~120 chars reads better in the feed.flair:is optional. Common r/mcp flairs include Show & Tell / Showcase, Discussion, Question / Help, Tutorial, News, Server, Client.- Quote the title (handles colons cleanly).
What ships with it
4 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.

reddit-mcp-post is a skill published in the GitHub repository richardwooding/file-search-on (5 stars, last pushed 2d ago), licensed MIT. It adds 155 tokens to every session and 1,203 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
