Description
Query Indian mutual fund NAV data, scheme info, and history via the free MFapi.in REST API.
Usage Guidance
This skill appears to do exactly what it says: query the public MFapi.in service for mutual fund NAVs. It requires curl and jq (or Python 3 to run the included script) and does not ask for any API keys. Things to consider before installing: (1) the included script will download and cache the full scheme list (~37k records) to /tmp/mfapi-schemes.json — this consumes bandwidth and disk space and the file may be world-readable on multi-user systems (the data itself is public). (2) There are no rate-limit guarantees from the API; avoid automated high-frequency polling to prevent abuse. (3) Ensure curl/jq/python are installed from trusted sources. Overall the components, instructions, and file access are coherent with the stated purpose.
Capability Analysis
Type: OpenClaw Skill
Name: mfapi
Version: 0.1.0
The skill bundle is benign. Both the `SKILL.md` documentation and the `scripts/get_nav.py` Python script align perfectly with the stated purpose of querying Indian mutual fund data from `api.mfapi.in`. The Python script safely performs network requests exclusively to the documented API endpoint and uses `/tmp/mfapi-schemes.json` for temporary caching, which is a standard practice. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, or prompt injection attempts against the AI agent.
Capability Assessment
Purpose & Capability
Name/description (query MFapi.in for NAVs/scheme info) match the requested binaries (curl, jq) and the included Python script. There are no unrelated credentials, binaries, or config paths requested; everything requested is proportionate to the stated functionality.
Instruction Scope
SKILL.md instructs the agent to call https://api.mfapi.in and to use curl/jq or the provided Python script. The Python script downloads the full scheme list (~37k entries) and caches it in /tmp/mfapi-schemes.json (auto-refresh after 24h or on cache-miss). This is within scope but note the large cached download and that the script writes to /tmp.
Install Mechanism
No install spec is provided (instruction-only). Examples use system packages (curl, jq) and the included Python script uses only the Python standard library. There are no external archive downloads or opaque install steps.
Credentials
No environment variables or credentials are required. The script only communicates with api.mfapi.in and does not request unrelated secrets or access to other services.
Persistence & Privilege
The skill is not always-enabled and uses normal autonomous invocation defaults. It creates a local cache at /tmp/mfapi-schemes.json which is ephemeral but world-readable on many systems; this is expected for caching public data but worth noting on multi-user systems.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install mfapi - After installation, invoke the skill by name or use
/mfapi - Provide required inputs per the skill's parameter spec and get structured output
