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 | $0.00033 | $0.00360 |
| Opus 5.5 | $0.00013 | $0.00144 |
| Sonnet 5.5 | $0.00007 | $0.00072 |
| Haiku 4.5 | $0.00003 | $0.00036 |
Grade A, and why
dir-mcp-config 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 1mo 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.
What it actually says
dir-mcp Configuration
When the user asks to configure dir-mcp — change the server address, set an auth token, switch auth mode, configure OIDC or TLS, or update the OASF schema URL — follow the configure-dir-mcp skill.
No config file
dir-mcp keeps no config file of its own. The MCP server reads DIRECTORY_CLIENT_* (and OASF_API_VALIDATION_SCHEMA_URL) environment variables directly, set in the agntcy-dir server's env block inside ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project).
The bundled dirctl binary additionally has its own, separate config with named contexts at ~/.config/dirctl/config.yaml — but that only affects direct dirctl invocations (e.g. dirctl auth login), never the MCP server's own tool calls. Don't conflate the two; see the configure-dir-mcp skill for the distinction.
Precedence
DIRECTORY_CLIENT_* env vars set in mcp.json's env block also override dirctl's selected context when dirctl is invoked directly, so keeping connection settings in that one place covers both.
After changes
Unlike the old config-file design, there's no watch-and-restart-on-change. After editing mcp.json's env block, reload the MCP server (Cursor's MCP panel, or restart Cursor) for the change to take effect.
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.

dir-mcp-config is a cursor rule published in the GitHub repository agntcy/dir-mcp (4 stars, last pushed 3d ago), licensed Apache-2.0. It adds 33 tokens to every session and 360 once invoked, about $0.0001 per session on Opus 5.5. 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.
