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 | $0.08065 | $0.08065 |
| Opus 5.5 | $0.03226 | $0.03226 |
| Sonnet 5.5 | $0.01613 | $0.01613 |
| Haiku 4.5 | $0.00806 | $0.00806 |
Grade A, and why
imf-mcp-server AGENTS.md 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 3d 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.
This is a copy
80% identical to obsidian-mcp-server AGENTS.md — 404 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 455 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Developer Protocol
Server: imf-mcp-server
Version: 0.4.4
Framework: @cyanheads/mcp-ts-core ^0.13.15
Engines: Bun ≥1.4.0, Node ≥24.0.0
MCP SDK: @modelcontextprotocol/server ^2.3.1
Zod: ^4.6.7
Read the framework docs first:
node_modules/@cyanheads/mcp-ts-core/CLAUDE.mdcontains the full API reference — builders, Context, error codes, exports, patterns. This file covers server-specific conventions only.
Server Overview
imf-mcp-server wraps the IMF SDMX 3.0 public portal. No API key required.
Surface area: 6 tools, 1 resource, 0 prompts.
Workflow: imf_list_databases → imf_get_database → imf_query_dataset. Large result sets spill to DataCanvas — imf_dataframe_describe then imf_dataframe_query for SQL access.
Key constraints:
- Country codes are ISO 3-letter (USA, GBR, DEU — not US, GB, DE)
- Key format is dot-separated DSD dimension order (e.g.
USA.NGDP_RPCH.Afor WEO) - Canvas spill requires
CANVAS_PROVIDER_TYPE=duckdb
Core Rules
- Logic throws, framework catches. Tool/resource handlers are pure — throw on failure, no
try/catch. PlainErroris fine; the framework catches, classifies, and formats. Use error factories (notFound(),validationError(), etc.) when the error code matters. - Use
ctx.logfor request-scoped logging. Noconsolecalls. - Use
ctx.statefor tenant-scoped storage. Never access persistence directly. - Need input the caller didn't supply?
return ctx.requestInput(...)and readctx.inputswhen the handler is re-entered. Neverawaitfor user input mid-handler. - Secrets in env vars only — never hardcoded.
- Cut noise. Add only what earns its place: no speculative generality, no guards for states the framework already prevents (Zod-validated params, classified errors), no abstraction until a third caller proves it, no option nothing sets.
- Close the loop on issues. When implementing work tracked by a GitHub issue, comment on the issue with what landed and close it. Do both — a comment without a close leaves stale issues open; a close without a comment leaves no record of what shipped. The comment is for future readers — state the concrete changes, not the conversation that produced them.
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.
