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 5.1 | $0.00069 | $0.01782 |
| Opus 5 | $0.00034 | $0.00891 |
| Sonnet 5 | $0.00014 | $0.00356 |
| Haiku 4.5 | $0.00007 | $0.00178 |
Grade D, and why
install-sentry-mcp scanned grade D with 2 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 9d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
`~/.env.mcp-sentry` (chmod 600), and launches the MCP process through that protected file. Add Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Adds Sentry access to your agent: list/inspect issues and events, read stack traces and breadcrumbs, query traces, and trigger Seer AI root-cause analysis. Official repository: https://github.com/getsentry/sentry-mcp — hosted endpoint: https://mcp.sentry.dev/mcp
Two methods
| Method | Auth | Secret stored | When |
|---|---|---|---|
| remote (recommended) | browser OAuth to mcp.sentry.dev |
none | SaaS sentry.io; simplest, most tools, auto-updated |
| stdio | user auth token | ~/.env.mcp-sentry |
self-hosted Sentry, or when a local process is required |
Prefer remote unless the user is on self-hosted Sentry or explicitly needs the local process.
Arguments
All optional — anything not passed is asked in Step 1.
| Token | Meaning |
|---|---|
claude / copilot |
which agent to configure |
remote / stdio |
install method (remote OAuth recommended; stdio for self-hosted Sentry) |
The access token is never accepted as an argument. For Copilot stdio, VS Code asks for it in a password
prompt when the server starts. For Claude stdio, the installer collects it in the terminal.
Quick Start
Collect parameters, then run the bundled script. Never request or pass an access token through a chat or command-line argument.
What ships with it
1 file 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.

install-sentry-mcp is a skill published in the GitHub repository jamesyang124/agent-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 69 tokens to every session and 1,782 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
